The revised N63TU is actually quite good. Although it is still called N63, it's a completely different engine. In fact, so good that it's still used to this day on 50i vehicles, albeit with a few updates over the years for the turbos. All problems lay in the pre-14 OG N63, which is what the care package aimed to solve.
I've heard this. Apparently the best way to identify the newer version is it makes 450hp to the earlier engines 405hp But then, a seller could just say what they want if it's in a vehicle around the time of the change?
From my experience the revised TSI engines that came with the MK7 Golf have been pretty reliable. The older 1.8/2.0 and twin charged 1.4 are particularly crap though. I don’t even understand what the point even was with the turbo- and supercharged 1.4 in the end. They ended up making a turbo only 1.4 with pretty much the same power while being way more reliable and no, it wasn’t laggy either.
Yeah the EA888 has been revised a few times since the Golf MK5 and VW has pretty much solved just about every single major issue, still may be the odd problem or so but generally the modern ones handle power well and don’t give much trouble. The engine is found in quite a few VWs and Audis
@@zectorr9 I’m not talking about the 20V 1.8T. I’m talking about the 1.8L TSI engine that replaced it. Specifically the earlier ones that often used absurd oil unless you spend quite a lot of money to have some updated pistons fitted.

Timing chains was not that strong either, but that was a common theme on all the early TSI engines regardless of displacement.
I had a 1984 dodge Daytona turbo Z. It was fun. Got it for $100. My dad rebuilt the engine and put a new turbo center section in and i ran it for a few years until i sold it to my brother. He sold it when the K member rusted out and broke. A friend of my sisters bought it and fixed it and drove it another 3 years without issue. Not terribly unreliable!

Your info on the 2.2 isn't accurate at all. I've owned 3 of them: 86' 2.2 Turbo 1 88' 2.2 Turbo 1 89' 2.2 Shelby Turbo 2 T1's produce around 142hp, while the T2 produced 175hp. The T1 is a turbocharger, T2 adds an intercooler, T3 doubles the valves and is DOHC. Each variation has upgraded internals. Your claim that there is no difference to the turbo charged engines is 100% incorrect. All of this information is plainly available on their Wikipedia page, it isn't even that hard to find. Finally, the headgasket issues are mostly due to coolant flow issues, as these engines are restrictive to cylinder 4, where a lot of these failures occur. That said, in my experience they have been incredibly robust little engines. My 88' was the first one I got, bought the car for $100 and it probably hadn't been maintained since the 90's. Thing not only ran but still held boost, a quick tune up and a resell and it's still running today.
As a 2.7t owner they really aren't that bad considering there's alot of first time stuff on it even now alot of stuff can be replaced to oe+ solutions and they run solid

I’ve had a ‘17 550i GT for a couple years now with the N63TU and it’s been great through about 50k miles of driving so far even lightly modified to FBO making somewhere in the 500HP range and driven pretty hard. I plan on slapping in some better turbos next to push it further. Maybe it’s because of the technical update but it’s been pretty solid for me at least for now.
My No. 1. FSO Polonez 1500 Turbo. It was so bad that not a single car with this engine has survived to this day (although it was produced since 1986). Its rally versions were nicknamed "Iron Rain". The engine is 1.5l ohv with a carburetor (rally cars, of course, better camshaft, head porting, etc.). Road versions reached 95-106hp (n/a about 75hp), rally 190Hp. Both versions had a very large turbo for such a small engine capacity. It was a communist copy of the KKK K26 or even K27.
I have a 2004 A6 SLine 2.7 biturbo . Had some oil leaks but upgrades fixed them. It has 30 valves, 5 per cylinder. And many running around with 1,000 hp on stock bottom ends with no worries. All engines have quirks. Most of these are fixed when you replaced the factory parts. I'm replacing all the factory brittle stuff right now. Note: this brittle black plastic is on EVERY motor, GM included. The power far outweighs the maintenance. And I'm an ASE tech.
One would that would make a lesser known turbocharged engine would be the K23A1. Only manufactured for the 1st gen 2007 - 2012 Acura RDX. Standard FWD, but can get SH-AWD. Sadly only available in automatic, but it is a very reliable engine.
A lot of the time the problem is the turbo getting to hot.. this can be due to a number of reasons, many of which can be remedied with aftermarket support or by simply adding vents or otherwise venting out the heat.. so a car that would be a timebomb can cheaply made reliable. Keep this in mind before precluding any particular car.
Yes, the bi turbo can be helped with thicker seals, maybe some surfacing to smooth mating surfaces, and a better cooling system. Yes those are not cheap to do but it’s possibly cheaper than having to rebuild the whole engine
2015 Elantra GT with the 2.0 THETA motor failed and Hyundai replaced it free of charge. The replacement engine has been absolutely spectacular! Approximately 180 HP and 160 lb.ft. in a 2800 pound Hatch. It has proven to be exceptionally capable and fun for daily driving! The GT's are also kind of rare so they stand out more than your average Hyundai.
I actually have a 2011 Sonata 2.0t Limited and the engine seized. It had 180k miles on it, which is vastly over warranty and hyundai still honored the replacement forever free.
After about 57K miles, I had to replace the 2.0 TFSI engine on my 2016 Audi TT, because it started burning oil (about 1 quart every 500 miles) due to a "scored cylinder #2". Warranty only went to 55K miles.
I think you should do a little more research on the 2.2 engines from Chrysler you got a lot of information wrong. Had 170 HP and eventually came with an intercooler they would out perform the Camaros from the same year.
@@RthereNEusernames the ecoboosts are pure garbage, they claim better mpg when in fact all you get is more moving parts to go bad, restricted airflow from a tiny turbo, a terrible cooling system, a crammed engine bay and equivalent or worse horsepower, torque and mpg compared to what a larger I4 engine would have
I was "lucky" enough to own a 1987 Turbo Sprint (Suzuki made) three cylinder with a whopping 70 hp on massive 13 inch tires.....it's problem? The turbo would never come on anywhere near the same rev range even in similar conditions. I'm not talking just a few hundred revs difference but far higher. Bought it new, owned it for about a year and a half and sold it. Also being tall and narrow I spun it a couple of times when the turbo kicked in.......and to show you how intelligent I was I traded in my 1986 Honda CRX Si because we needed a back seat for podlings.....didn't put that little tidbit on my resume......
I blame ever stricter emissions regulations and customers demands for ever increasing unreliability. Engines need to make more power, less pollution, be quieter, go longer without a service, do more MPG etc etc etc than ever before. Sometimes it's all of the above things.
Engines are complicated machines consisting of hundreds of parts all working in conjunction. Hundreds of things that can go wrong. To make this system more complicated by adding a turbocharger adds to the list of things that can go wrong.
12:09 finally someone doesn’t talk so much smack about the cooper S. You just have to specific what engine and generation. You showed 3 different generations of Minis. I’m guessing you’re talking about the N14 turbocharged engine which is the most unreliable engine from the R56 mini. The N18 (found in later R56) and W11 (found in all R53) are decently reliable. I been owning an R53 for two years already and the only problem I had was a power steering leak and a coolant leak.
My brother had a Turbo Cooper S. It was constantly breaking down. The turbo went out before 40k miles, the timing chain tensioner had to be replaced twice and the hood scoop melted because it was just a fake piece of plastic.
Why does it seem as if many of today's modern engines are prone to premature failure? It could be due to car manufacturers propensity to use plastic, cheaper metallurgy processes, and smaller engines. A twin turbo four will be able to put out more HP and torque than a six cylinder, but it has to work harder to do so. It will not last as long or be as reliable in most cases.
I was with bmw as a tech with the customer care packages came out and a problem created by doing the injectors was if you didn’t use the special tool to remove them from the cylinder head it would wallow out a hole for the new injectors that would exasurbate the problem and car would come back with a check engine light for misfiring the only way to fix it replace the cylinder head.
I own a couple Audi's... One is a "full bolt on" E85 and methanol injection B5 A4 with the 1.8T. It's not done yet... The other is a 2014 A4 with a EA888 2.0T, big innercooler, intake and tune. Timing chain stretch is still a thing, the tensioner was what actually failed on the earlier one. I replaced all the chains and tensions at 80K along with getting rid of the plastic water pump. Then a few thousand miles later burnt through an exhaust valve because #2 injector was clogged. Easy fix but had to take the head off to do it.
I've had my A6 2.7T for 8 years now. Timing is SO EASY to do as long as you go on Amazon and buy the timing tools for $30 and follow torque specs. Buy OE and OEM parts and you won't touch timing in 75k. My car is the COP ignition version. But yes, the turbos blow, especially if tuned. Car is going on its 3rd set of turbos. I went k04s last time, now it's k04 hybrids pushing close to 500hp. I find the car easy to work on (minus the turbos) and the aftermarket is HUGE. If the car body becomes unusable I'm throwing that 2.7T into another body, VW makes it somewhat simple to swap it into another VAG car. Even a Porsche 911.
Looking at the bi turbo. I’m Shure some collector would hate me for wanting to make one reliable since it looks like the main issue is it needs a beefy cooling system and maybe some thicker seals.yes I know that you are talking about stock ones I’m just giving out advice that might help y’all. Also, when replacing your flywheel, replace your rear main seal
Just wanted to say, my father owned a Shelby omni glh with the 2.2 turbo and it was honestly one of the most beat on and reliable car i think he's ever owned.. Raced more v8s than I can count but then again he let it cool down between runs because he knew better. Probably just his mechanical knowledge that kept it reliable but nonetheless.. I wish he never got rid of it.
My e888 gen 3 in my mk7 gti has been bulletproof so far. 6 years and 68k miles....almost all of those tuned. Original water pump, although i'll probably have to replace it next year.
Thought this was going to be a Scotty Kilmer “provoke a reaction”type video. With a 130k road miles in one 310hp 2.7T and 20k 80% track miles in a different 520hp example. I can say it’s pretty on the money about the Audi twin turbo v6.
You could add navistar maxxforce 11 and 13 to that list. I wouldn't have a truck in my fleet with that engine if it was given to me for free. Yes they are that bad.
Your Chrysler 2.2 info is wrong. The original 2.2 turbo 1 produced 142 bhp in 1984 and had different pistons, in 1985 power went to 146 bhp. These were not slow, they were faster than the F body and Mustang. In 1987 Turbo II (intercooled) to 175bhp.
So glad I bought a first model year 2015 GTI with the EA888 instead of a Mk6 or Mk5 with the Problematic engine 😭😭 Like yeah we still have problems on the EA888 but at least our timing chains don't snap like that
9:15 I have to note that the Old chain drive 2.0T's still have the code EA888. The EA888 gen 1 and 2 motors are the shitty chain drive ones, I have a gen 2 and practically everything you listed has gone wrong, though some of the issues are gen 1 or 2 specific. I.e. oil consumption due to bad rings was a gen 2 problem, worn camshafts from the HPFP plunger was a gen 1 problem, most of the others occur in both motors. The 2014 revision is the EA888 gen 3.
Almost all of the information for the 80s Chrysler’s is wrong… You didn’t research them at all before posting this did you? lmao 2.2 carb 107hp 2.2 turbo 1 makes 146hp 2.2 turbo 2 makes 175hp 2.2 Turbo 3 makes 225 2.5 carb makes 113hp 2.5 turbo 1 makes 150hp 2.5 turbo 2 makes 180hp 2.5 turbo 3 makes 300hp They make good daily’s and can easily make more power without much effort and cheaply. I daily quite a few of them and have even drove them across the country without issues.
I think Volvo always made the best turbocharged engines. The B230FT is probably the most reliable turbo gas powered engine of all time. The newer 5 cylinders weren't as reliable as the B230 but still way more reliable than any of the competition. I've owned Volvos for 16 years and never had any more problems with the turbocharged models over the non turbocharged models.
I’m a big Honda & Toyota guy but what Honda did was by far one of the dumbest things ever seen they took one of the most reliable engines in the world the the 3.5L v6 on the Accord with 277 HP and replaced it with a 1.5l turbocharged 4cyl making 195hp and getting the same fuel economy and 82 less horsepower way to go Honda u nailed it there
Mazdaspeed Protege 2.0t was a normal 2.0 with a turbo slapped on it. It made 170 hp stock and I recall hearing it liked to come apart with even mild side increases of boost. Pretty sure the 2.3t in the MX-7 was a dumpster fire if an engine too.
Where the hell did you get your info on the 2.2 chrysler motors? Your wrong about everything. And Carol Shelby got a restricted 170 hp. From it. The 2.2 turbos made 148hp and around 170 ft lb torque. I had about 8 of them and never had any problems you listed. The motor was originally made in the old slant 6 factory and was originally gonna be diesel for about 25 pounds of boost. Find a better resource for info on them.

I'm surprised the N54 didn't make it here, since it was BMW's first mass-produced turbocharged engine and is usually bashed for its unreliability, though the N63 is arguably worse lol.
I own a ‘15 with the Tu engine and have put over 60K miles on it in my ownership, not one drop of oil used in between changes throughout my entire ownership. The only maintenance I’ve had to do was regarding coolant lines under the hood that was actually a pretty cheap fix

But I would like to add the shitty ford eco boost 1.6-2.0 turbo motors that they put in the focus, fusion, escape land rovers evoque , and even the jaguar xe, what a pile of 💩 those are !

Dodge Omni. My folks had one and it was fun until it wasn't. It was the most unreliable car I have ever been in. It wouldn't start or would die for no apparent reason, frequently.
I think there was a miss read on the BMW engine it’s not 15,000 it’s 1500 miles If anybody drives a car passed 3000 miles without getting an oil change you deserve what’s coming to you
Mazda 2.5 n/a engines solves a lot of problems :) No turbo, better sound, much more reliable, can be tuned to about 200hp with 0-60 for 7sec. Who needs more. Turbo`s for trucks.
Very rarely will the icms fail completely.. usually only one channel gets lost. Also original borg warner turbos will last a long time when you don’t abuse the car (and run a shitty ”stage” tune) timing job on this motor is not that hard as you are making it.. you can build the tools by yourself and locking pins you can just use drill bits.. using oem quality parts (ina, mahle, continental, behr etc) will ensure you don’t have to replace those parts early. Ofcourse the 2.7t has its problems (SAI, icm, occasional boost and vaccuum leaks camshaft seals and the non updated pvc with no heating are the most problematic) I’ve had 3 2.7t cars (A6 C5 allroad tip, A6 C5 Tip and currently daily driving a S4 B5 (k04 RS4 clutch etc small mods) with 410k km, zero issues in 5 years😊) Maintain the 2.7t with proper parts and it’ll last a lifetime..
I own n63 and it’s a great engine,it’s not nearly as bad as this guy who I’m sure doesn’t own one makes it out to seem. I find running high mileage ones all the time. Americans treat cars like trash and you can’t do that with an engine like the n63. It’s a turbocharged V8 for heavens sake,once you beat the heat it’ll run just fine.
What's the worst turbocharged engine you know of?

I actually have a 2011 Sonata 2.0t Limited and the engine seized. It had 180k miles on it, which is vastly over warranty and hyundai still honored the replacement forever free.
The Chrysler 2.2 Turbo I engine was rated at 146 hp, not 107 hp. The Turbo II in the GLH-S was rated at 175 hp.
After about 57K miles, I had to replace the 2.0 TFSI engine on my 2016 Audi TT, because it started burning oil (about 1 quart every 500 miles) due to a "scored cylinder #2". Warranty only went to 55K miles.
I think you should do a little more research on the 2.2 engines from Chrysler you got a lot of information wrong. Had 170 HP and eventually came with an intercooler they would out perform the Camaros from the same year.
I'm surprised none of the Ford Ecoboosts made it to the list
Why would they?
Well They Can Burn Down In Some Mustangs
@@RthereNEusernamesthe 1.0 is a pos and i have experience blowing up 2 2.0 ecoboosts in my old st
@@ButteredUpToast i blew up the turbo on my 1.6fiesta while it was still stock😂
@@RthereNEusernames the ecoboosts are pure garbage, they claim better mpg when in fact all you get is more moving parts to go bad, restricted airflow from a tiny turbo, a terrible cooling system, a crammed engine bay and equivalent or worse horsepower, torque and mpg compared to what a larger I4 engine would have
ea888 wastegate rattle was annoying but a easy fix, timing chain and hpfp was also pretty easy
I was "lucky" enough to own a 1987 Turbo Sprint (Suzuki made) three cylinder with a whopping 70 hp on massive 13 inch tires.....it's problem? The turbo would never come on anywhere near the same rev range even in similar conditions. I'm not talking just a few hundred revs difference but far higher. Bought it new, owned it for about a year and a half and sold it. Also being tall and narrow I spun it a couple of times when the turbo kicked in.......and to show you how intelligent I was I traded in my 1986 Honda CRX Si because we needed a back seat for podlings.....didn't put that little tidbit on my resume......
I blame ever stricter emissions regulations and customers demands for ever increasing unreliability.
Engines need to make more power, less pollution, be quieter, go longer without a service, do more MPG etc etc etc than ever before.
Sometimes it's all of the above things.
Engines are complicated machines consisting of hundreds of parts all working in conjunction. Hundreds of things that can go wrong. To make this system more complicated by adding a turbocharger adds to the list of things that can go wrong.
12:09 finally someone doesn’t talk so much smack about the cooper S. You just have to specific what engine and generation. You showed 3 different generations of Minis. I’m guessing you’re talking about the N14 turbocharged engine which is the most unreliable engine from the R56 mini. The N18 (found in later R56) and W11 (found in all R53) are decently reliable. I been owning an R53 for two years already and the only problem I had was a power steering leak and a coolant leak.
Ha ha. I turbocharged my Honda d16Z6 17 years ago and I still daily drive the thing. Nothing broken.
My brother had a Turbo Cooper S. It was constantly breaking down. The turbo went out before 40k miles, the timing chain tensioner had to be replaced twice and the hood scoop melted because it was just a fake piece of plastic.
yup, the n14 was pretty bad but the n18 solved nearly all the issues of the n18 all of the big ones at least. Sucks that he had all those issues tho
Why does it seem as if many of today's modern engines are prone to premature failure? It could be due to car manufacturers propensity to use plastic, cheaper metallurgy processes, and smaller engines. A twin turbo four will be able to put out more HP and torque than a six cylinder, but it has to work harder to do so. It will not last as long or be as reliable in most cases.
B58 has been good so far.
Fun fact (or potentially accurate belief), it is equally strong as the 2jz. What a 2jz can handle, a b58 can handle.
@@Josh-qm4rb its better mod for mod power gain wise.
@@Josh-qm4rb I prefer the N55. It’s amazing!!!!!
Uh oh. This'll be interesting...
That BMW motor!!! Oh man, stick with BMW straight 6's.
Indeed
True
I was with bmw as a tech with the customer care packages came out and a problem created by doing the injectors was if you didn’t use the special tool to remove them from the cylinder head it would wallow out a hole for the new injectors that would exasurbate the problem and car would come back with a check engine light for misfiring the only way to fix it replace the cylinder head.
I have a 2.7 and I love it.
Smoke a lot of new cars with it and it sounds great.
I own a couple Audi's... One is a "full bolt on" E85 and methanol injection B5 A4 with the 1.8T. It's not done yet... The other is a 2014 A4 with a EA888 2.0T, big innercooler, intake and tune. Timing chain stretch is still a thing, the tensioner was what actually failed on the earlier one. I replaced all the chains and tensions at 80K along with getting rid of the plastic water pump. Then a few thousand miles later burnt through an exhaust valve because #2 injector was clogged. Easy fix but had to take the head off to do it.
I've had my A6 2.7T for 8 years now. Timing is SO EASY to do as long as you go on Amazon and buy the timing tools for $30 and follow torque specs. Buy OE and OEM parts and you won't touch timing in 75k. My car is the COP ignition version. But yes, the turbos blow, especially if tuned. Car is going on its 3rd set of turbos. I went k04s last time, now it's k04 hybrids pushing close to 500hp. I find the car easy to work on (minus the turbos) and the aftermarket is HUGE. If the car body becomes unusable I'm throwing that 2.7T into another body, VW makes it somewhat simple to swap it into another VAG car. Even a Porsche 911.
Looking at the bi turbo. I’m Shure some collector would hate me for wanting to make one reliable since it looks like the main issue is it needs a beefy cooling system and maybe some thicker seals.yes I know that you are talking about stock ones I’m just giving out advice that might help y’all. Also, when replacing your flywheel, replace your rear main seal
Just wanted to say, my father owned a Shelby omni glh with the 2.2 turbo and it was honestly one of the most beat on and reliable car i think he's ever owned.. Raced more v8s than I can count but then again he let it cool down between runs because he knew better. Probably just his mechanical knowledge that kept it reliable but nonetheless.. I wish he never got rid of it.
My e888 gen 3 in my mk7 gti has been bulletproof so far. 6 years and 68k miles....almost all of those tuned. Original water pump, although i'll probably have to replace it next year.
Stay on it. Mine went out at 92k mi
I haven’t watched the video yet, but the Chevy Cruze better be on this list.
Thought this was going to be a Scotty Kilmer “provoke a reaction”type video. With a 130k road miles in one 310hp 2.7T and 20k 80% track miles in a different 520hp example. I can say it’s pretty on the money about the Audi twin turbo v6.
I'm surprised the 13B isn't on the list, rotaries are always on these type of videos 😅
Reminder that we Full send our engines constantly and complain when they break but continue to fix them up to do it all again
Man, hard for me to believe you guys skipped over the G54b. Makes a bmw look like Honda for reliability.
You could add navistar maxxforce 11 and 13 to that list. I wouldn't have a truck in my fleet with that engine if it was given to me for free. Yes they are that bad.
Your Chrysler 2.2 info is wrong. The original 2.2 turbo 1 produced 142 bhp in 1984 and had different pistons, in 1985 power went to 146 bhp. These were not slow, they were faster than the F body and Mustang. In 1987 Turbo II (intercooled) to 175bhp.
So glad I bought a first model year 2015 GTI with the EA888 instead of a Mk6 or Mk5 with the Problematic engine 😭😭 Like yeah we still have problems on the EA888 but at least our timing chains don't snap like that
Maserati engines aren't that unreliable, it's just that people do NOT know how to maintain them. The real problem was the cooling
9:15 I have to note that the Old chain drive 2.0T's still have the code EA888. The EA888 gen 1 and 2 motors are the shitty chain drive ones, I have a gen 2 and practically everything you listed has gone wrong, though some of the issues are gen 1 or 2 specific. I.e. oil consumption due to bad rings was a gen 2 problem, worn camshafts from the HPFP plunger was a gen 1 problem, most of the others occur in both motors. The 2014 revision is the EA888 gen 3.
Almost all of the information for the 80s Chrysler’s is wrong…
You didn’t research them at all before posting this did you? lmao
2.2 carb 107hp
2.2 turbo 1 makes 146hp
2.2 turbo 2 makes 175hp
2.2 Turbo 3 makes 225
2.5 carb makes 113hp
2.5 turbo 1 makes 150hp
2.5 turbo 2 makes 180hp
2.5 turbo 3 makes 300hp
They make good daily’s and can easily make more power without much effort and cheaply. I daily quite a few of them and have even drove them across the country without issues.
I think Volvo always made the best turbocharged engines. The B230FT is probably the most reliable turbo gas powered engine of all time. The newer 5 cylinders weren't as reliable as the B230 but still way more reliable than any of the competition. I've owned Volvos for 16 years and never had any more problems with the turbocharged models over the non turbocharged models.
Why you do the b5 like that I love my expensive shit box
The Chrysler Turbo I made a minimum 147 HP, the 107 hp 2.2 was the Carborated H.O.
How did the ecotec 1.4 not make the list?
The ecotec z16xep is just as terrible
I was surprised too lol. I own one but I actually maintain it so it’s been reliable. I’m actually tuned on it and it’s been great
ecotecs are definitely better than any of these on the list, they’re not great but the ones on the list are piles of hotdogs
I’m a big Honda & Toyota guy but what Honda did was by far one of the dumbest things ever seen they took one of the most reliable engines in the world the the 3.5L v6 on the Accord with 277 HP and replaced it with a 1.5l turbocharged 4cyl making 195hp and getting the same fuel economy and 82 less horsepower way to go Honda u nailed it there
Chrysler built a 2008 PT cruiser with a 2.4L turbo. Had over heating problems & the turbo charger went out at about 30,000 miles….
Ford Ecoboost should be on the list.
Mazdaspeed Protege 2.0t was a normal 2.0 with a turbo slapped on it. It made 170 hp stock and I recall hearing it liked to come apart with even mild side increases of boost.
Pretty sure the 2.3t in the MX-7 was a dumpster fire if an engine too.
Where the hell did you get your info on the 2.2 chrysler motors? Your wrong about everything. And Carol Shelby got a restricted 170 hp. From it. The 2.2 turbos made 148hp and around 170 ft lb torque. I had about 8 of them and never had any problems you listed. The motor was originally made in the old slant 6 factory and was originally gonna be diesel for about 25 pounds of boost. Find a better resource for info on them.
Volkswagen 1.2/1.4 TSI (EA111), Volkswagen 2.0 TDI PD (EA188), Fiat 0.9 TwinAir, Opel 1.6/2.0 SIDI, Toyota 2.0/2.2 D-4D, Renault 1.5dCi, Citroen 2.7 V6 HDi, Citroen 1.2 PureTech (EB2DT i EB2DTS).
40 hrs of labour! What's the average hourly rate for a good reputable mechanic?
The Chevy Cruze with the 1.4L turbo has all these problems combined into one package and somehow didn't make the list
My b5 s4 has been parked in my driveway for months now 😂😂
How mercedes m270 engines? Any good?
I'm surprised the N54 didn't make it here, since it was BMW's first mass-produced turbocharged engine and is usually bashed for its unreliability, though the N63 is arguably worse lol.
Do you know if they fix these problems in a 2016 550i that's what I was planning on buying???please help if anybody knows
I own a ‘15 with the Tu engine and have put over 60K miles on it in my ownership, not one drop of oil used in between changes throughout my entire ownership. The only maintenance I’ve had to do was regarding coolant lines under the hood that was actually a pretty cheap fix
Subaru EJs are like pitbulls… There’s certainly some bad apples, but most of the time it’s the owner that’s the problem
As an Ase certified tech who worked for Vw/ Audi 8 years I approve of this list! But I would like to add the shitty ford eco boost 1.6-2.0 turbo motors that they put in the focus, fusion, escape land rovers evoque , and even the jaguar xe, what a pile of 💩 those are ! Even the v6 eco boost in the f150 suck🥶
the turbo on the 1.6 hdi on peugeot is also unreliable because there would constantly be an oil leak
N54 equipped BMW’s should have been mentioned. Engine internals aren’t bad, it’s just everything on the outside of the engine is garbage.
07 Mini S. Loved that car but couldn’t keep out of the shop.
These videos always make my day
Pontiac V8 Turbo.
How car you use a picture of this m5 and the engine didn't appear on list. If I'm not mistaken this belongs to rk autowerks. It's one of the 12 imola f10 m5s
Nice video brother. N63 Or the whole N6x Gen is not a shocker to be on the list.
My 1.6 TGdi engine cracked a Ringland, at 75k miles, might have been my fault but still that shouldn't happen.
Pray for my ea888 mk6
Dodge Omni. My folks had one and it was fun until it wasn't. It was the most unreliable car I have ever been in. It wouldn't start or would die for no apparent reason, frequently.
I owned a 94 Plymouth Sundance with a swapped 2.2 turbo sold the engine when the body rotted out
1990 Daytona Shelby Turbo Z - 1 quart of oil per 400 miles. But fast as hell.
Vw 1,4 tsi twincharger. It has mostly the same problems as the 2.0t. But the big one is that pistons crack in the ringlands🤣
I think there was a miss read on the BMW engine it’s not 15,000 it’s 1500 miles If anybody drives a car passed 3000 miles without getting an oil change you deserve what’s coming to you
You forgot one, the 2.3L Turbo I4 in the Ford Focus RS
Mazda 2.5 n/a engines solves a lot of problems :) No turbo, better sound, much more reliable, can be tuned to about 200hp with 0-60 for 7sec. Who needs more. Turbo`s for trucks.
Very rarely will the icms fail completely.. usually only one channel gets lost. Also original borg warner turbos will last a long time when you don’t abuse the car (and run a shitty ”stage” tune)
timing job on this motor is not that hard as you are making it.. you can build the tools by yourself and locking pins you can just use drill bits.. using oem quality parts (ina, mahle, continental, behr etc) will ensure you don’t have to replace those parts early.
Ofcourse the 2.7t has its problems (SAI, icm, occasional boost and vaccuum leaks camshaft seals and the non updated pvc with no heating are the most problematic)
I’ve had 3 2.7t cars (A6 C5 allroad tip, A6 C5 Tip and currently daily driving a S4 B5 (k04 RS4 clutch etc small mods) with 410k km, zero issues in 5 years😊)
Maintain the 2.7t with proper parts and it’ll last a lifetime..
my fully forged rebuilt 1.8 turbo 20 valve BAM engine is perfect
My S63 M5C is a beast.
I owned the charger with the 4 cylinder turbo, it was horrible, I finally gave the car away for nothing.
I own n63 and it’s a great engine,it’s not nearly as bad as this guy who I’m sure doesn’t own one makes it out to seem. I find running high mileage ones all the time. Americans treat cars like trash and you can’t do that with an engine like the n63. It’s a turbocharged V8 for heavens sake,once you beat the heat it’ll run just fine.
Gas prices making v8 and v10 less appealing.. V12 like the Northstar engine will probably never be made again 🤦🏽♂️
Well you used my video is the intro clip and got alot of info about the 2.2 turbo dodges wrong! That black csx made 530 whp with a 2.2 dohc
Try the n54 motor in the bmw 335i, engine solid everything around it? Garbage.
In summary: BMW, audi and hyundai engines
Was expecting the 2.3mzr as an honorable mention
I had a Plymouth Duster turbo, 5 spd, that little thing would get down.
Don't forget about 300zx twin Turbos ...will give you nightmares😱
Nah those engines were stout
