Here's weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. Here are some of my favorites:
GM Vortex 8100 • LOCKED UP BIG BLOCK 8....
F150 5.0 Coyote Gen 1 • 11-14 Ford F150 5.0L C...
8.0L Ram V10 • 8 LITERS OF DESTRUCTIO...
Audi V10 • DEVASTATED Audi S6 5.2...
Today's teardown is a core return from an engine we sold. We sold an engine out of a Mitsubishi Lancer Ralliart, a 4B11T. The Ralliart is a lower power output level version of the Lancer Evolution, which is the same engine with a bigger turbo and more boost. The buyer of our good engine was fairly unsure that we'd want his core back but YES, finally I have the chance to get one on the channel and wow was this one hurt. In this video we tear it down to see what happened, and what can be saved.
Why am I doing this? My name is Eric and I own and run a full service auto salvage business called Importapart. Part of our model includes dismantling blown and bad engines to salvage the good parts to resell. We do not rebuild engines, merely supply parts to those who do.
I really hope you enjoyed this teardown, as always I love all of the comments, feedback and even the criticism. Catch you on the next one!

Granny must have shocked when that gently stalled at a light on her way to bingo.
She only drove it twice a week. Church on Sundays, and Tuesday night bingo. Never revved it over 2000 rpm.
Looks more like the engine went out about 1/4 mile after the lights went green 😂
If it was my grandmother, probably. She is 91 and loves to floor it in her Tesla. 😂
I agree. This was obviously a low rpm failure that no one could have predicted. I suspect metal fatigue. 🥸👍👀✅❗️
Granny done unlocked confetti mode in the oil pan there.
"I thought we agreed, No Car Parts In Bed", Wife is next level.
“You must admit, it is a very attractive water pump…”. Apologies to Dr. Katz
I had a pex 90° elbow in my bed once. Imma plumber 🤫
That damn near killed me! Laughed so hard.
We can tell who watched it to the very end 😂
@robertwest3093 once I saw him safeguard the water pump I had to see where he was going with it.
Anyone else else immediately see the wrist pin as soon as he dropped the pan and think damn, that’s ready to go back on the shelf in inventory
I remember that episode where a wrist pin was destroyed.
As soon as he pulled the remnants of the piston from cyl. 3, I thought "well, the wrist pin is probably fine. It may have been flung out the side of the block along with the rod, but wherever it is, it's fine"
What are those things made out of? Unobtainium-titanium alloy?
There's no point putting them on the shelf. Nobody ever needs to replace one. If aliens turn up a million years from now, they'll wonder what this planet of only wrist pins was.
We used old piston pins as press tools!
"Now, let's pull the party pan." You were a standup comedian in your previous life, weren't you?
He's actually Adam Sandler's lost cousin....
@@mattjacomos2795 True! What baffles me is that nobody else seems to notice the similarity between "SuperfastMatt" and comedian Tom Lennon (Reno 911). (Maybe because they haven't heard of Tom Lennon, lol.)
I make that same connection. I'm often thinking Adam Sandler.@@mattjacomos2795
@TassieLorenzo I see it more "We're The Millers" than Reno, but Superdry Matt is more Steven Wright...
He got me cracking at that point too!😂
"This is a door, and you can't see thru it." I love the comically timing right at the beginning 😂😂
Love the ending of the water pump story. Taking the water pump skit to a whole new level. 🤣🤣🤣🤣🤣
Those golf ball dimples(pock marks) arent from debris, thats from pinging(knock). That chunk missing from Cyl 2 piston wasnt a debris, thats was a hellatious pinging event that did massive damage, either boost controller failed and sent ALL the boost or fuel pressure dropped at full send and the engine went badly lean. Either way can kill and engine before you can pull the foot away. Previous owner got ALL the enjoyment from that one.
in the end, bigbaddaboom
@@jpkalishek4586 big boom indeed
I think you are spot on with the went lean comment, Had one of those engines in a 2010 Genny coupe, We had done a lot of work on the bottom end and also changed cams out , larger injectors / turbo way to much power for the size of the engine. Had interlocks all over to try and prevent the engine from coming apart (AFR monitoring / fuel rail pressure monitoring etc.) all the interlocks that you could put on one to try to save it in an over boost or fuel pressure loss scenario. Fuel pump went kerplunk on a full send (playing around on an 1/4 mile weekend of racing) and even the computer could not stop it in time (spark kill) detonation sent a piston into the pan. bought a kit to stuff an ls into that little coupe and to be honest I had more fun with the little turbo 4 (Weight front to rear was great before stuffing the v8 in it)
Agree, looks like catastrophic detonation.
You finally got a 4B11t! I was never going to make a comment until you have my car in a video
Lancers are a joke
@@TrySomeFentanylTodayyou take that back RIGHT NOW
Lancers are a joke. Now the Evo is a different story as is the rally art version. The base Lancer is a pile of scrap.
Looks like someone was trying to build a cheap EVO
With the amount of lower end damage I was half expecting the engine to just come apart when the timing cover was removed.
When he pulled the head, I thought the block would fall in two pieces to the left and right with the crank holding them together!
Regarding the van - I do hope the handicap modification equipment is recoverable. They're extremely valuable to those who need it, regardless of cost.
Now Saturdays complete 👌
… Sunday in Australia
@@stuartscott60 You are already living in the future lol
The RR engine had its pan cut in half by the mechanics, not by the blow, this is #1 so far in terms of block carnage I think.
"No car parts in bed......" Priceless!
Oh, man! I had a 2014 Evo X MR ... that thing was a rocket on rails!!
It was not an uncommon thing for people to blow those engines, not from lack of maintenance, but from over-boosting w/o beefing up the rest of the engine, then running at WOT for extended periods. It's disconcerting hearing one of those screaming along, then hear half-second of SCREEE--BANG!
Gotta love those customers that help Eric's bottom line, one heavy right foot at a time ....
My daughter and I have been bonding over your videos for a few years now. When it’s time for bed she asks if we can watch an engine video. She asked why you wrapped that part up and put it in the car, “is he going to fix that when he gets home” she asked, lol. Or she’ll ask, “ why did he throw that part, he can’t sell it?” 😂. Thanks for the great content. If I ever need a first gen 5.0 for my f150 I’ll be giving you a call.
That makes me smile 😁
That ending gave me quite the chuckle!! Was not expecting that!
As a Subie owner, it excites me to find out you got a Mitsubishi engine, particularly from the Evos. It will absolutely compliment very well to the Subie engine carnage from the first 2024 video.
As an owner of a '99 Eclipse GSX, I'd love to see you get a 4G63 in.
Thank you for making amazing videos!
As a Mitsi owner driver for 51 years, I loved this teardown. I really enjoyed the simplicity of design and ease of disassembly compared to so many US designed engines. Keep up the good work. Lots of respect from Australia.
To bend a crank lobe like that is insane!
No when it gets insane is when you break a forged 5150 billet steel crankshaft. I saw a guy break one of those in a highly modified Big Cam Cummins engine. It spit the entire #3 rod journal out of the side of the block along with most of the connecting rod and cylinder sleeve. The #3 piston was wedged in the hole the rod created in the block.
@@haroldbenton979 Ouch
Glad to see you give that water pump the proper care and handling it deserves
I have an '03 Lancer with 175,000+ miles on it. I'm thankful it's not an Evo cause knowing how the previous owner treated it (anything besides an oil change and maybe a tune up was not happening), I seriously doubt it would be on the road now.😮
I love your channel, and I'm always excited to see what (hopeful) carnage awaits me every Saturday night.
My 03 has 222000...engine is still great.
every time eric wraps a water pump angel gets his wings
So, the fact there was no sludge, or varnish, makes me think the owner truly maintained his car... except the cooling system ;-)
and lived the redline life
Looks like the sludge never got time to settle.
What happened to the cooling system? Just the wrong coolant or incorrectly mixed? Using OEM pre-mixed coolant definitely makes things easier, as navigating aftermarket coolants is a minefield. Coolant colour bares no relation to chemistry, which is helpful lol.
I appreciate the Jackie Gleason reference in the video screenshot
Those companies you reference @ 1:50 or so are like the four horsemen of the autocalypse
Thats so painfully true. Although I feel like they’re all horsemen these days
@@I_Do_Cars toyota being the outlier aside from the new twin turbo V6
@@derp527 they’re the least evil but all these new turbo engines replacing low stress v6’s and v8’s is a recipe for trouble
@@I_Do_Cars They are an MBA recipe for selling more engines, parts, and cars. All these idiots want cars to be like iPhones, expensive and disposable.
@@I_Do_Carsonce you read the book “the toyota way” and you learn their philosophy, youll understand that wouldn’t make that decision if A) they werent forced to by emissions laws and B) wouldn’t release an engine that they weren’t 100 percent behind.
When I rebuilt my 3.5 V6 in my 2009 Impala I lost the surclips for the pistons. Bought some retaining rings from the hardware store and bent them to the right size. Over 10k miles still runs perfectly 👌
If I'm right, you are talking about the clips that holds the rocker arm to the piston skirt....and you pulled off a homemade job; you are good or lucky. I think it holds some sort of a pin in the hole of the skirt.
We use CIRCLIPS here, much better.
Redneck engineering FTW
@@patverum9051 OH NO I SPELLED IT WRONG OMG NOW WHAT?
@deplorablelibertarian yeah it holds the wrist pin in the piston. I may not know how to spell but I do know how to rebuild an engine lol
Waterpumps with a lot of impeller pitting can be a sign of cavitation due to high-RPM operation, particularly with a higher percentage of water in the system than normal. I suspect that pump was an aftermarket part.
Also, coolant chemistry is off. Change your coolant on time.
@@MrApplesaucestuff I googled it and apparently Mitsubishis use blue OEM coolant, though coolant colour doesn't mean a lot with the various aftermarket coolants (as long as it's silicate and borate free as Japanese cars tend to require due to their seal formulation). Hmm, apparently the phosphate-free formulation of universal blue coolants (European car suitable) doesn't offer the protection (against aluminium corrosion) of the phosphates used in Japanese coolants. [I.e., the universal blue long-life OAT coolants are phosphate-free AND silicate and borate free to try to please everybody.] Maybe I should use OE coolant instead of universal blue coolant? 🤔
Eric you should go back and check the top of cylinder #2 for ring ridge, if the engine was running without the top compression ring it should show up in the ring ridge.
Lancers have been a long standing popular car in Australia dating back to the late 70s. Both my kids have had one. I still have. They have lasted pretty well, but the Evo was made for rallying and very successfully for a while, but it has to have been one of the most hot rodded cars ever. They get absolutely flogged. We don't see the other brands using similar engines so much, but Mitsubishi has a pretty good reputation here. I've had 3 mid size Magna (about Sonata size)sedans all good cars none of them from new and no complaints.
No complaints about my 380😅.
I once read a book called. "You Can't Get Here From There", It was about the very first 2 Mitsubishi cars to come to Australia about 1966, I get that date from where I was when news of a Plane Crash near Winton Australia in which one of the occupants of the cars was supposed to be, only they missed the flight because of some bush bashing they were involved in that could not be replicated in our more modern 4x4s. Because of their lightness they crossed a mostly dry river that nothing else would be able to be carried by 4 men. Those 2 cars arrived in Sydney and didn't even get across the Harbour Bridge before the drivers seat colapsed and yet they went on to do marvelous things , to North Queensland then over the inland to Adelaide South Australia. Wow well worth a read if that book can be found today.
As a Costa Rican, my father used to say that most people prefer them to toyotas,as sure,the toyotas are reliable,but Mitsubishi's had a certain "sturdiness" in all environments, and held off better overall
Take that for what you will, i never owned a Mitsu tho
The early stuff we got as Dodges, the rear drive Lancer and some models Galant as Colt or Challenger, and Plymouth Sapporo and a Sigma as an Arrow or Colt wagon, Arrow and D50 pickups (Mighty Max). When they went to the Belt Drive cams, as well as selling as Mitsubishis, a bit of the reliability seemed to go away. While not known to just blow up, they would start to have seal issues at 60,000 miles (100,000 km) or so, especially the front drive cars in the '90s. Some of the other issues were assembly plant based issues, Made in the USA in plants run with Chrysler Corp. who were never the top of QC. most of the other issues I saw came down to bad maintenance/neglect
Anyway, I love the old ones, and was sorely tempted to buy a '75 or '76 Colt (Lancer with a 1.6/4speed manual) with only 75,000 miles (120,000 km) on it for $4495 that was listed out of Indiana a few weeks back. It looked Cherry for the miles let alone the years. I've had 3 Colts (non-balance motor 2.0 GT, and 2 '76 models with 1.6l and one of those had a 2.6 from a Galant/Sapporo swapped in) and a Dodge D50 pickup that had the 2.0 swapped to a 2.6.
The Arrow was the worst car I ever owned. Dead cylinder at 77k
I would just LOVE to hear the story/recollection of this inspection port installing situation.
Funny, but back 1988 in high school my good friend bought a 1972 FJ 40 Landcruiser and it developed a misfire. He drove it all year and during the summer, I did a compression test on the 2F engine and #1 cylinder was dead. Pulled the cylinder head and the crown of the piston was stuck on top dead center of the block and the rod and the pressed in wrist pin were moving about freely in the bore of the cylinder. The wrist pin wore a groove in the block 5mm deep in the block. 😂 got a love the gutless indestructible Toyota 2F engine
Just a light hone and away it went again?
@@JohnSmith-yv6eq A bit of Weld it goo will fix it.
Guy had to be racing when it blew up. Massive carnage.
Definitely looks like one of my engines. Meticulously serviced, always warmed up before WOT, doted on, washed and dried, but always suffering under just a measly quarter pound too much boost until its over.
Love the inspection ports,of course😊 My car is modified significantly, so this video keeps me praying more now
I owned a 2004 Mitsubishi Lancer ES. It had a fuel injected 4g94 2.0 liter 140hp. Did the maintenance, and it had 241,000 miles before my youngest had an accident with it. Didn't burn oil, but it was starting to show it's age.
In the 90's i had a 1986 Mitsubishi Mirage Turbo. It was my second car and was hard to find replacement parts for. I was hard on the transmission in particular. Well, luckily Hyundai Transmissions fit right in and allowed me to keep sending it. I went through at least 3 transitions on that thing. Fun fact, i had a HKS cat back exhaust on it! Not the best car, but it was fun at the time.
What were the 3 transitions? Male female...female male
@@mikefoehr235 i missed that autocorrect.... transmissions. I killed 3 transmissions in that thing.
Good thing that the engine is fully dressed around you know, windows.
19:01 Dropping oil pan, "sounds like a cash register" I was expecting you to yell "CHA-CHING!!"
That motor was knocking from an improper tune, it was gonna go soon anyway because the clearances on these motors aren't OK for too much more than stock boost, but the issue here was knocking. I've seen this exact thing before. These engines in design are really tough and if people took the time to swap forged pistons and do the bearing clearances right, they're up there with k series as far as strength goes.
I really like this channel - a great combination of knowledge, analysis and humor. A great way to spend a little time in the evening after a challenging day.
It was just started and left to warm up in the driveway when this happened.
Only driven to church on Sundays.
Absolutely stock. . . honest!
Thanks for sharing.
I was having a tough day until I got the notice that your video was up..... Thanks Eric! By the way..... does your wife know about your timing chain problem? LOL
Great tear down. Those bent bolts are crazy!
The last Evo X was a 2015, so the timing guides were replaced sometime. It is my understanding that the 2008 and early 2009 4B11T came with a timing chain that did not last. Later versions did last.
The engine may have been an OEM replacement. That could be another reason for the 2017 markings on the timing guides. If you are really lucky, that head has the sodium filled exhaust valves also seen on the 2015 Evo X Final Edition. The sodium valves and some reprogramming gave it 313 horsepower instead of 295. That makes the core more valuable.
It's another situation where someone changes oil on schedule, but doesn't do anything else for maintenance. Does anyone else get motivated to change their antifreeze when watching these videos?
There used to be a good writeup on a Korean blog showing the difference between the 4b11T and the Theta II from a genesis coupe. Looks like the blog was taken down in the last few years. But it showed how similar and how different they were.
Key points:
The theta is an open deck, 4b11t is a semi closed deck
The theta has an extra hole for the water pump
The 4b11t has 4 bolt mains, Theta only has 2 bolt mains
Of course the pistons and rods are different, 4b11t has a lot stronger internals.
From they way it was explained to me Mitsubishi rejected the design and Hyundai/Kia bought it. Then Mitsubishi reinforced the weak areas. Sure Hyundai/Kia still have the crankshaft defect that they blame everything on but I'm sure there's more to that than we know.
I have a 2012 Sonata 2.0T with 256k miles on it (it's been tuned well over 200k miles and still kicking). With these cars you don't push them when something is wrong. I'm guessing this was a tuning mishap, possibly fuel related. Cylinder 3 likes to go in the Theta II as well, the first thought was that it was the exhaust manifold design of #3 being the shortest runner. Though many belive it's just a design flaw of the block. Those HKS plugs are heat range 8 (I run M45's which are heat range 9), those plugs are tough as hell. They can take a lot of detonation and will still be fine.
It would be great to get ahold of top fuel engine. Of course those aren't really something you normally just get, so maybe a guest from a drag car team to take one apart
I just want to say thanks. Love your videos even though I'll never work on many of these, i love watching!
Love the content! I wish these videos were around when I was younger and in auto mech school.
Engine (Hand Grenaded) from being repeatedly over revved ! No signs of running without oil like burned up bearings, etc. Just KaBOOOOOOM !
I installed headers on my 11 Camaro SS. With your trials and travails lurking in my memory, I approached the dipstick with the ferocity/menacing look of a '90s WWF star. Giving the stick a few tentative turns, I jerked on it with all my might... and ended up on the floor with it in my hands. It's all your fault. Cool vid, as always.
Congratulations on 300k subs as well, from ERICK to ERIC keep up the great work sir
I think this was one of my favorite teardowns. The carnage is amazing and I'll bet when that thing let go, it was a sight and sound to behold. As always, Eric, you do such a great job explaining what you find and entertain us with your humor. I love everyone of your videos and look forward to the weekend when I know there will be another great teardown waiting for me to watch. Blessings!
That was carnage! This is why I love this channel. Enthusiasts famous last words: "I can get even more HP if I boost the turbo a little bit more!".
The spark plugs are the only things that you can resell. 🙄Keep these great videos coming.
bro you been dropping bangers recently good work
I love that design. Such a simple, easy to maintain engine. Probably cheap and quick to manufacture.
Ohh Man, it's Sunday morning here in Copenhagen and I have a new episode of I Do Carnage. Yay - and thanks for all your incredible videos.
saturday nights are fantastic again thanks for dropping new vids the carnage does look like it made a loud bada boom thanks eric
My dad is 77. He has recently moved in with me. I have shown him your videos in the past. In fact I drop them in the family chat on WhatsApp. He said you lost weight. All that for 1 line, but with context. He had a few laughs with your video last night.
Brilliant breakdown - some serious energy unleashed when that one popped. I once had a catastrophic failure of a (of all things) a year 2000 Volvo V40 T4 wagon (4 cylinder, 2 litre turbo, 200 bhp) which I’d had from new with about 120,000 miles on it. At around x8 mph, I had very little warning - a brief flash of the oil pressure light (ironically only topped up a few days prior), a microsecond later there was about 1 second of horrendous grinding noise followed by a very loud bang as a rod made a partially successful bid for freedom and as it introduced itself to the radiator and intercooler. End of Volvo. Reason was a disconnected oil cooling pipe which flushed out the old oil in record time. Everywhere. Great ending. Mrs Eric is a star !
Yay ! I've wanted to see a Mitsubishi engine for while now :) thank you !
'I thought we said, no car parts in bed?' Repeat offender eh? I'm proud of ya!
As alittle boy, I took my first leather football to bed😅.
Dude the beginning is awesome xD beautiful analogy
I love how you admired that timing chain like it was a 24k gold necklace. 😆
Love the ending. My son, and I were wondering as we watched that you hadn’t done much with the water pump. We are kind of disappointed, but as usual you never disappoint. Thanks for all your videos.
The parting moment of the video is, well...
Epic.
Eric?
@@JohnSmith-yv6eq Is that the name of the water pump?
Quick disconnect piston option. Another great video, thank you!
Good teardown, funny ending. Thanks for sharing your videos. 👍
Has anyone else noticed the emergency fire extinguisher and chocolate pudding on the middle engine rack? 0:57 I’ve noticed this the past 5 tear downs.
I must ask, I understand the fire extinguisher but the pudding? I gotta know why is that there? 😂😂
Old MB engine video, was tasty pudding
th-cam.com/video/_j9vMzgnyfc/w-d-xo.htmlsi=HkQJRg65B527IRZ9
You don't have an emergency pudding supply for when you get hungry and it's not lunch yet?
Never too old for a pudding cup
It's a lot of work putting out fires. A guy's gotta keep his energy up.
The Snack-Pacs are a Billy Madison reference, Eric also drops the occasional Adam Sandler quote in tear downs after a few people said they look alike.
Outstanding video
I haven’t seen the inside of one of those since I left the Mitsubishi dealer in 15. Great video.
water pump was hilarious, also amazing to see a bmw power hatch that still works lol
I do really want to see a teardown of a modified Subaru engine. They can be wild :)
Thank you Lancer guy and thank you Mrs. Megan.
Reminds me of that Honda V6 you got a while back. That was incredible
Ran across one of your vids as a YT Recommen while watching Speedkar99, and have been binging like crazy.
Pretty far from a prude, but honestly one of the best YT'ers in about every category one could mention.
No click-baiting, no crazy music, or begging to 'smash that like' is big plus.
Lots of technical detail, occasional tangential takes that are either fun or informative.
Doesn't feel the need to drop the f-bomb, etc every other sentence, which is probably nice for Dad's to watch with their kids.
Catches the innuendo discreetly, and honestly is pretty funny without going over the top and painfully forcing it.
My wish list for future video would also be a few more of the 3-cylinder motors that seem to be becoming more common.
Crazy how different engines seem to be now compared to 80's 302/350's.
looks easy to wrench on. pretty basic tools. thank you for the video.
OK, that ending was hilarious! :)
Thanks Eric for my Saturday night entertainment.
Could you possibly tear down a 7.3 international idi turbo? Pre ignition cups and keystone rings would be awesome to see. Keep up the good work and hilarious jokes and sketches.
Great video as usual. Also great water pump skit!
This was exactly what I needed today.
I'm glad I could fulfill your order!
Looking good, great video.
Eric,
I love it all - thank you!
Pal (in MA)
Hi boost and overrev. Piston failed at wristpin. Then whirlybird. Well done Eric. Great humor and comments.
Overrev on a downshift?
Love the closing!
Great video! Would love to see the base 4B11 or larger 4B12 torn down as well.
I've watched this about 4 times already keep falling asleep mid vid pray for me here goes number 5😂
We need to see a 4G63 or 4G46 on this channel for a tear down
Thank you Eric!👍
I've never a two piece bedplate before.lol. The A853 engine in my Neon SRT-4 is cast iron and is a split crankcase design with a bedplate like in this one. But those never rip themselves in half because aluminum, no matter how light it is, will never ever out perform steel! 🎉
Those marks on the pistons are a clear sign of engine knocking badly, most probably by a bad tune. Sustained knocking usually lead to bent or broken rods or cracked pistons.
Carnage. Total Awesome Glorious Carnage!
"That blowed up REALLL good"
Car parts in bed is one of those kinks with a solemn, devoted but quiet following.
Must have been a big fun drift or launch to pop that hard
That is one impressive crankshaft to not have broken apart!
A few things to note here.
some people say these are like a hyundai based on the theta 2 - theta 2 turbo engine. it isnt. the NA 4b11 shares alot with the theta 2 but the 4B11T is over 90% different regarding parts, block ect.
The NA version of the 4b11 and the theta 2 NA and turbo version share alot, but when it came down to the 4B11t only mistubishi engeneer's developed this engine even though it was in alliance with GEMA. first of all the NA 4b11, theta 2 NA and turbo versions are all open deck block design's.
The 4b11t is a semi-closed deck that had alot of reinforcement's for the high pressure's in the cylinder's. it also has cast iron cylinder liners as stock, no balance shaft is needed for this engine, oil.water passages are different. whats unique about the 4b11t is that it has 4 bolt main caps, witch is really unheard of in a inline 4 engine, this idea was carryed across from porsche race engine's. a high flow water and oil pump as well as other goodies are present on the 4b11t. The mivec cam's on the intake and exhaust help out alot with turbo spool ect, an example here would be an efr 9180 T4 turbo on a 3.0 litre 6 cylinder toyota supra vs the same efr on a 4b11t 4 cylinder evo engine. the 4b11t equiped with the T4 efr came on boost slightly before the Supra.
The pistons in the evo x 4b11t engine are forged as is the crank and rods, although the rods are recommended to be changed after making 400 torque.
There are some difference's with the ralliart 4b11t vs the evo x 4b11t. Turbo on a ralliart is a smaller single scroll turbo, where as the evo x has a twin scroll larger turbocharger, witch is slightly bigger than a T3 turbo regarding its size. the ralliart has no oil cooler, the evo x has an external oil radiator type oil cooler behind the fog lights. intercooler is smaller on the ralliart, there might be a couple more things i missed out but you get the point. chassis wise there are alot of differences regarding the ralliart and evo x. the ralliart is based of a regular fwd lancer, where as the evo x is a completely different chassis with 4 wheel drive and turbo in mind, different drivetrain, suspention, brakes, ect are all different on the evo x aswell.
just some downsides to the 4b11t.
Please make sure you change the fuel pump relay fuse yearly to make sure your not running lean on boost and potentially puttting a whole in the block, just like what happened here by the looks of it. The old black omron relays are not to be trusted, the problem here is when the fuel pump relay goes into stage 2 on WOT the conectors can and get defective pritty quick, witch leans out the fuel a hell of alot and can result in a bent rod, rod through the block ect ect. The lastest Fuel pump relay is the orange one by panasonic. ill leave the part number below to the latest fuel pump relay, these are solid state relays unlike the old one's.
Evo X Fuel Pump Relay
OEM Part Number For Reference: 8627A049
Another downside is the timing chain, the old version that came on early 4b11t's can stretch over time, mitsu released an updated version with a redesigned chain link witch solves the stretch problem, although not everyone has issues with the old chains, as long as your useing high quality oil such as Motul 300v, millers CFS NT+ or AMSOIL sig series. and changing oil regularly, with top tier oil's. These engines don't respond well to cheap stuff or mid grade stuff. i would change every 6 months or every 3000 miles, or every track session.
Also use top tier gas/petrol, these are sensitive on fuel, it responds poorly to cheap/ low quality fuel. even more so on moddified engines witch again can cause damage to these engine on WOT useing the cheap stuff.
another issue for the evo x is the OEM top mounts, witch can knock fairly early in its life if your car is lowered.
The 4b11t has been out of number of year's now, and has proved to be a very stout engine and reliable. maintenance is so important with these engines, as they don't react well to sub par - minimal maintenance. Also if these are tuned then it has to be tuned correctly or problem's will surely arise.
Ideas for future tear downs:
-Ford/Yamaha 3.0/3.2 SHO V6
-Gen 3 SHO 3.4L 60 degree V8
-Duratec 3.0 V6
-Anything with 5 valves per cylinder (all the rage 20+ years ago). Audi might be the easiest to find
I've blown up two engines: a 1200cc VW in a Formula V that was stock and an MR2 which was also raced.
