Awesome video Musa! It's a good thing to mention that the gen 1 B46/B48 engine eseentially have the same TD04 turbo as the N20 which features a .41 exhuast housing that REALLY restricts exhaust flow for over 350whp even for a 2.0! Thats makes the IM450 a huge upgrade over the gen 1 turbos. Loved your explanation on the dual-ceramic ball bearing, its the biggest reason why we can keep the stock-like spool with a much stronger top end 💪. Super excited about your build.
Thank you! Very interesting, I wasn't aware that the gen 1 didn't utilize a Honeywell turbo as well. I'm sure a lot of F3X drivers will be stoked to know the IM450 isn't reserved for the G2X platform and technically could be even more transformative for their cars. I'll be sure to mention this in the install video. Thanks, going BB was definitely the move for our cars, excellent design decision.
@@Starscream8896 Still a very considerable amount. The B46TU turbo comes with a relatively small compressor wheel. Stock turbo 91 you can expect 290whp whereas with an IM450 you can expect 360-380whp like Musa mentioned in the video. Where this turbo really shines is with ethanol mixes or even meth injection especially in places with subpar gasoline like California. You can easily break the 400whp mark without sacrificing spool.
@@Starscream8896 California? Nope not yet, but we do have a comparable fuel in italy that did dyno 380whp. If you're in california we really reccomend just running ethanol mixes and even better port injection full e85 to not bother with mixes and be full power the safest way possible. Ethanol has very big cooling benefits and compared to the abysmal qualify of california gas its a no brainer.
@@mondragonmsaul308 yes basically, the b38 (3 cylinder), b48 (4 cylinder) and b58 (6 cylinder) all use the same bore and stroke cylinders. I'm no expert but you bet they use a lot of overlapping technologies.
Nice explanation. Agree that turbo 4 cylinder cars are the future but I still love the sound, reliability and smoothness of my “old fashioned”, naturally aspirated, in-line 6 cylinder n52 engine.
@@FnGRZupra I would tend to agree in the larger cars but my n52 is in a very light 128i cabrio and with the top down on a beautiful day while taking a “spirited” drive through the backroads, the smoothness of the 6 cylinders is intoxicating and being “slow” is the last thing I think about.
Great video.. appreciate the easy to follow technical explanation! Could you consider doing a video covering the differences between the Gen 1 B48 (in the F-chassis) versus the new Gen 2 B48?
my next car is gonna be b48 powered, glad you started covering them. Its easy to answer why bmw does this, most people want least amount of lag and most power at lower rpm for daily eco driving
For sure, I think they also need to factor in competition from entry level electric cars. These turbo 4 cylinder cars are going to need to start offering 300+ HP from the factory IMO to compete. Not everyone would opt for the hybrid version.
Great vid and the N20 is the little engine that could. I bought my gf a 2014 428i back in 2016 and it's still going strong with just reg maintenance. The torque is great on it and would surprise a lot of people who hate the 4 banger BMW engines.
Just found this channel. Thank you sir for explaining twin scroll turbos and how to max power out of these B48s. As soon as my G20 warranty expires, I’m all in on following your footsteps.
Great video Musa! I have been following you for the last 5 years since I got my first E90 and you are what motivated me to start making my own videos. The way you explain things is so simple and I've learned so much from you!
Thank you! Thanks for following for so long and congrats on the channel, at a quick glance I can tell you're crushing it. It's great hearing stories like this, the community will be a better place because of it.
i don't even own a Bmw but im hooked to your channel! you level of engeniering expertise is delightful to be honest man! You actually achieved to position in my mind the possibility of an 220i with this turbo, should be a pocket monster.
Been a couple weeks since you popped up on my feed while searching for a new car, curiosity sparked when you posted the power potential the B48 has and today marks the first day of owning a 2020 G20.
Hello mate! I follow your project. But before installing new turbo I think you should do dyno run and show us graphs and then do test runs with something like dragy on same road, same direction, same amount of fuel. It would be more objective testing. Thanks for effort into making this video about great project!
I purposely kept the car stock and skipped going with a stage 2 tune or downpipe etc so we can just assume the car is producing stock HP which is around 250 WHP and 300 WTQ to start.
If my 230i was paid off I’d be right behind you with the turbo upgrade. I’m still under warranty so I just can’t do it right now. My main concern is if this will run into overheating. Hopefully the stock cooling can handle the power. For a daily this won’t be an issue but if you plan to do a track day then there is definitely some concerns. Also good job on creating content. I appreciate your knowledge and experience. These B48 engines are a performance bargain and massively under appreciated. While everyone is over paying for Civic Type R, GR Corolla, and Nissan Z, you can easily get a 30i BMW with ease and reliably modify for more hp.
the n26 was the first motor, in my first car, pretty reliable till I blew it on monday due to oil starvation on a high G left hand turn. Overall super reliable if you did the work yourself, I had it stage 2 tuned using Bootmod3 OTS and it ran fine for 2 years on that
Thank you so much for everything I've been looking for my n20 to get 500hp I found everything to replace every plastic bit in the entire system, and I just needed to find something to get over 300
Very good information, I really appreciate your video's very much! Do you mind me asking, if you buy a majority of BMW parts from Bosh, are they all OEM or not the same quality?
Thanks! I tried to stick with OE supplies and the brands can range. There are quite a few OE suppliers, MANN, Continental, Bosch, Febi, etc etc. Good part supplier websites typically recommend OE options when searching, I partner with ECS tuning and use their website to see what good OE options there are for a particular model.
My BMW with B48 always smells like oil after a 20min drive. I cannot see any oil leaks but I do see vapours at the oil cap and a lot of oil dust sitting between injectors and oil dust on the head gaskets. But no seaping oil leaks. Even BMW dealer confirmed this too.
A heads up, the holes in the compressor cover are meant to reduce/mitigate compressor surge. Not for sound. Yes, it will sound like a Jet engine, but thats not the purpose of it, just a consequence of having air "leak" there
Appreciate your effort in making all these videos relating to B48 tuning capabilities! Really useful information. I just have a question over the downpipe option; would the use of high-flow catted downpipe impact the projected whp much?
Great video and a new subscriber here. Question: I have a 2022 Supra 2.0 with the B46/48. Would adding the JB+ ( not JB4) require that I upgrade any part of the engine as it adds 20-30hp and torque?
Interesting vid. I have the N54 twin, and wanted to ask you a question about those turbos. A guy in our CCA, who also has a N54 solved the lag/low-end/high-end power problem by putting a slightly bigger than stock turbo with a larger turbo as his twins. So he still has the low-end torque and relatively no lag, and yet still gets tons of power on the high-end. His car is really fast, and I was thinking about doing the same thing. But I haven't gotten all the details on exactly what he used yet. What is your opinion on using different sized turbos on the N54 platform for a more power and better turbo power range, with very little lag???
Awesome content! I didn't know that the exhaust manifold was that complex and the "Gunther" design impressed me again. Does the hybrids have different turbos, since the electric motor handles the lack of spool?
I'd have to do some more digging but from what I found that is the trend now, leaving more tuning potential on the table. For instance the 330e in the G20 came with the B48B20A engine but eventually started coming with B48B20B and they can make more HP. Would just need to look into the specs of that turbo on the B48B20B to say definitely as from what I could tell the B48B20A uses the same turbo as the 330i. Maybe someone can chime in with more information.
@@VehicularDIY Any chance to see the turbo model w/o blowing up the whole engine? I have a G30 530e 2017 originally sold to Sweden, so I could check the turbo model with an endoscope or something. I'll not mess with the car, since I want to sell it soon, but I'm considering the G20 330e xdrive next and I want that to be faster. Doesn't realoem show the precise part numbers? (Finland tax heavy the emissions = hybrids are cheaper to buy and own)
Okay I did a little research. If you're going with a G20 330E you're going to want to make sure it has the B48B20B engine as it has more potential with tuning. Mostly due to the internals of the engine being more like the B46D from what I have read. The electric motor provides over 100HP right from a stop and it seems as though from a cost standpoint there was no need to run a different turbo on the 330E vs the 330i. As time progresses and the hybrid models become more prevalent I expect to see them pushing the turbocharger sizing and shooting for more HP and supplementing the lack of spool with electric power.
This was great! My BMW is 6 cylinder, twin turbo, however I do have a 4 cylinder vehicle and this turbo has me wondering if it would be applicable. Anyway, great stuff as usual.🎉
Guys I love your channel, I currently have a 2012 528xi, my sons and I have torn it down to the block. We discovered that cyl 3,4 really got heated up enough to scorch the rod bearings. We took it to a machine shop here in OMaha, they checked out the crank real quick and they can machine thos to rod beariing journals with no problem, the crank journals are very goo no problem there however, my question to you is can I purchase some after market connecting rods (4) or can I just replace the cyl #3,#4 rods with the after market ones. I have a veRy limited budget and I really don't want to spend $200+ for an OEM connecting rod. Secondly the pistons and rings and the cylinders are very good with no scoring or any damage. Can I just put/replace new rods w/o doing anything to the pistons/rings? I'd really appreciate you feedback/recommendations/, Thankns for all you guys do, keep up the good work! Larry/omaha
That is why I love my K20C with the factory turbo. Sure, there are bigger turbo's, but with a custom tune, pushing 370lbft of torque at 2k RPM and 290-300lbft at 1500RPM is insane and feels way stronger than any NA 6 cylinder ever could. On pump gas. But, the downside of this turbo (the MHI TD03) is that it is single scroll, and once reach your peak you fall off rapidly past 4800-5000 RPM. Sure, with better tuning we got a better top end, but that is with 6 PSI of boost more than factory and lots of custom tuning and boost by gear, etc. There really isn't a good turbo replacement for the k20 that will be a drop in replacement that can maintain both low end an top end torque. As far as I know, neither PRL nor 27won offer a twin scroll turbo. Which sucks.
Great content but... I think your viewers have much more technical knowledge than you give us credit for, evident in the simple way you describe everything. Not hating, just some input, we are here because we are major gear heads after all 👍🏼👍🏼
Alfa tuners I am told keep the turbo tune 400 HP max because the ZF Transmission can't handle much more reliably. I thought the BMW 2.0 used the same ZF unit, so wouldn't 500 HP be overkill for that transmission ?
Hey do you have any good videos for someone pretty knowledgable in cars but doesn’t know much about how the engine actually works and the different parts of the engine
Could you tell us your take on n20 engines, are they any reliable up to 300hp in their stock form if serviced on time? What mileage is expected to get out of them before any major rebuild?
I just bought a im500 with the t51r mod I have a 2017 bmw 430i gran coupe I got the vrsf down pipe I wish I would of bought the ipos one first but I got a csf heat exchanger Injen intake ( I have a Ecs turbo inlet but I believe the turbo comes with a inlet correct me if I’m wrong ) also I have a awe exhaust I just don’t have a mid pipe yet any advice on what I should get ? Also my goal is 450 hp but still be able to daily it I was thinking of getting the port induction kit but with the im450 u said u can get like 380 with 93 octane do u think the Im500 would get more on 93 or should I just get the port induction kit ? Also who do u think would be the best tuner for my build ??
I have a few questions. I have a 2018 330ix completely stock. 1) with a DownPipe that dize and no aftermarket exhaust, will it cause droning? 2) Will a charge pipe upgrade be needed along with this? 3) and lastly, we’re talking 400 crank hp SAFELY on stock internals? So we’re just doing im450, DownPipe and tune. That’s it? - thanks I’m interested
No in comfort mode you would be hard pressed to tell it isn't stock. This assumes under 20% throttle in normal driving. It can get loud in sport plus and higher rpms but it's not super loud. Not required, I'm keeping mine for a stock look. If I wasn't concerned about that I would have upgraded it. They can hold the boost though from what I've seen, not like on the older cars with the clip on style at the throttle body. This has a flange and bolts down so it can handle more even though it's plastic. In your case because you have an F30 you would need to upgrade the HPFP as well to a Gen 2 like what comes stock on my car. So turbo, downpipe, gen 2 fuel pump and tune and easy 400 crank hp safe on stock internals. IPOS which I linked below sells the HPFP upgrade also. I say safe in terms of power as you could aim for deep into the 500 crank hp range and still have it last. For comparison if you had a 2015 328i you'd be at the limit at 350 crank for a number of reasons.
@@VehicularDIY thanks for the reply brother excited to see how this all turns out I’ll be with it for every step. In depth Videos like yours make me want to pull the trigger on my upgrades
750,000 miles behind N52 motors, we just bought an X3 MSport w/ the N20. Around town, the torque does motivate this chassis. However, the sound and vibration... Sorry BMW, BIG mistake. PS... we got better fuel efficiency in the N52 X3 than this N20!? At 190,000 miles, the N54 was averaging 23.5mpg. The N20 w/ 70,000 miles is getting 21mpg.
What upgrace do you recommend for a JCW f60 2023? I would like to add another 100 horsepower. most important is reliability is the family car we go to Disney with. I added a eventuri intake and hard pipe. I can't get upgrade parts information for this engine
Regarding the B48's, would you consider the 320i 184hp version to be reliable to tune with a stage 1 mod or will it be risky since these have the higher compression pistons compared to the ones found in the 330i ? Would be really nice to see a video regarding the different B48 versions. I only found other engines on the MHD site, any idea if they plan to develop a B48 tune too ?
Hey, so I have an N20, yet it keeps having a hard lurch when accelerating hard going from first to second gear. It is almost non-existent when the car is cold, but gets worse after warming up/driving. I have already changed the driveshaft, auto transmission (ZF), CV axles, and still have not fixed this problem. Any ideas? I really want to keep this BMW because it is so smooth on the highways. It is an F10. Thanks. I just cannot figure out what could be wrong with it. No engine codes come up. It also hesitates when going uphill and has a transient "drivetrain malfunction" that pops up but goes away when then going back to driving on flat road. Already checked the spark plugs and ignition coils and no difference unfortunately.
It is a great shame Toyota refused to put a manual transmission with the BMW B48 Supra. It is lighter than B58 car. It handles better than the B58 car. All simply to protect the sales of pathethic GR86 which now suffers from oil starvation they refuse to warranty.
A B48 with a manual could be fun on a true sports car like the Supra. On my 330i I would definitely want auto as it's the daily with assisted driving. On my driveway I have two manual cars right now and one auto.
Apparently a b48 g20 manual was available in other countries😢 like for the 320d. Would have been cool to have a 6 speed 330i considering the world record for the 2.0 honda accord quarter mile time is with a manual transmission.
I have a gen 1 b48, how do you not blow the pistons i know the rods and cam are b58 so it can take it I thought the pistons heads (NOT included bearings) can only barley take 320hp, or is it the turbo? How much can the piston heads take then?
One more question, am i right in saming the gen 1 and 2 b48 have the same transmission as the b58 aswell, the ZF8HP50 cause that thing can take up to 650 nm torque easy and safety only starts getting sketchy plus 800nm
I have to wonder tho, are the pistons, rods, crankshaft, head bolts, etc all ready for 400hp+ when it was never intended for it. Wouldn't you need to be upgrading much more to make this power reliably?
Awesome video Musa! It's a good thing to mention that the gen 1 B46/B48 engine eseentially have the same TD04 turbo as the N20 which features a .41 exhuast housing that REALLY restricts exhaust flow for over 350whp even for a 2.0!

Okay I did a little research. If you're going with a G20 330E you're going to want to make sure it has the B48B20B engine as it has more potential with tuning. Mostly due to the internals of the engine being more like the B46D from what I have read. The electric motor provides over 100HP right from a stop and it seems as though from a cost standpoint there was no need to run a different turbo on the 330E vs the 330i. As time progresses and the hybrid models become more prevalent I expect to see them pushing the turbocharger sizing and shooting for more HP and supplementing the lack of spool with electric power.
@@VehicularDIYi can vouch for this same turbos on 320, 330e and 330i
Just have to fix the balancing issue of the 4 cylinders now. Interesting video thanks
4 cyl is problematic due the design .. unrelated to BMW, just physics law.
your content is very good, thank you
Im excited about the B48 in terms of the future for MINI, F56 B48 minis are a untapped performance bargain
Any thoughts on pros/cons of JB+ (not JB4) tune for the B48? I own a 2022 2.0 Supra. Great video and you have a new subscriber! Thanks
Would a bigger turbo work 5:55 with high conpression b48a?
This was great!
My BMW is 6 cylinder, twin turbo, however I do have a 4 cylinder vehicle and this turbo has me wondering if it would be applicable.
Anyway, great stuff as usual.🎉
its not a twin turbo lol
Twin power* its a single turbo
A masterclass of Turbos

Love your content brother
During the N20 turbo explanation, I keep staring uncomfortably at the water pump. That pump scares me.
You work is great, sir 🙏
Would love to see what a turbo mod do on the B48 on the 2 series Gran coupe xdrive. Already gets decent gains from new intake and axle back.
Thank you for these videos
Hey great video I do wonder though if the rest of the engine can handle it, or if pistons and crankshaft should be upgraded as well?
Guys I love your channel, I currently have a 2012 528xi, my sons and I have torn it down to the block. We discovered that cyl 3,4 really got heated up enough to scorch the rod bearings. We took it to a machine shop here in OMaha, they checked out the crank real quick and they can machine thos to rod beariing journals with no problem, the crank journals are very goo no problem there however, my question to you is can I purchase some after market connecting rods (4) or can I just replace the cyl #3,#4 rods with the after market ones. I have a veRy limited budget and I really don't want to spend $200+ for an OEM connecting rod. Secondly the pistons and rings and the cylinders are very good with no scoring or any damage. Can I just put/replace new rods w/o doing anything to the pistons/rings? I'd really appreciate you feedback/recommendations/, Thankns for all you guys do, keep up the good work!

would love to see some more f36 440i content.
I'll for sure get back into some gen1 B58 content in the future.
So I've been wondering about this. Since you moved to California, are you allowed to use catless downpipes?
That is why I love my K20C with the factory turbo. Sure, there are bigger turbo's, but with a custom tune, pushing 370lbft of torque at 2k RPM and 290-300lbft at 1500RPM is insane and feels way stronger than any NA 6 cylinder ever could. On pump gas. But, the downside of this turbo (the MHI TD03) is that it is single scroll, and once reach your peak you fall off rapidly past 4800-5000 RPM. Sure, with better tuning we got a better top end, but that is with 6 PSI of boost more than factory and lots of custom tuning and boost by gear, etc.
There really isn't a good turbo replacement for the k20 that will be a drop in replacement that can maintain both low end an top end torque. As far as I know, neither PRL nor 27won offer a twin scroll turbo. Which sucks.
Great content but... I think your viewers have much more technical knowledge than you give us credit for, evident in the simple way you describe everything. Not hating, just some input, we are here because we are major gear heads after all 👍🏼👍🏼
Alfa tuners I am told keep the turbo tune 400 HP max because the ZF Transmission can't handle much more reliably. I thought the BMW 2.0 used the same ZF unit, so wouldn't 500 HP be overkill for that transmission ?
Im pretty sure same transmission as b58 ZF8HP50
I approve this video
Hey do you have any good videos for someone pretty knowledgable in cars but doesn’t know much about how the engine actually works and the different parts of the engine
I want it.
Are you a professional mechanic? You seem to have expertise rarely seen in DIY videos.
Could you tell us your take on n20 engines, are they any reliable up to 300hp in their stock form if serviced on time? What mileage is expected to get out of them before any major rebuild?
how does this turbo compare to the b48e turbo? its usually considered an upgrade on the factory b48 turbo.
I already have a VRSF down pipe. Will it work with the turbo? Or do I need to use the company’s down pipe?
I just bought a im500 with the t51r mod I have a 2017 bmw 430i gran coupe I got the vrsf down pipe I wish I would of bought the ipos one first but I got a csf heat exchanger Injen intake ( I have a Ecs turbo inlet but I believe the turbo comes with a inlet correct me if I’m wrong ) also I have a awe exhaust I just don’t have a mid pipe yet any advice on what I should get ? Also my goal is 450 hp but still be able to daily it I was thinking of getting the port induction kit but with the im450 u said u can get like 380 with 93 octane do u think the Im500 would get more on 93 or should I just get the port induction kit ? Also who do u think would be the best tuner for my build ??
What turbo would you recommend for B58TU?
I have a few questions. I have a 2018 330ix completely stock.
1) with a DownPipe that dize and no aftermarket exhaust, will it cause droning?
2) Will a charge pipe upgrade be needed along with this?
3) and lastly, we’re talking 400 crank hp SAFELY on stock internals? So we’re just doing im450, DownPipe and tune. That’s it? - thanks I’m interested
No in comfort mode you would be hard pressed to tell it isn't stock. This assumes under 20% throttle in normal driving. It can get loud in sport plus and higher rpms but it's not super loud.
Not required, I'm keeping mine for a stock look. If I wasn't concerned about that I would have upgraded it. They can hold the boost though from what I've seen, not like on the older cars with the clip on style at the throttle body. This has a flange and bolts down so it can handle more even though it's plastic.
In your case because you have an F30 you would need to upgrade the HPFP as well to a Gen 2 like what comes stock on my car. So turbo, downpipe, gen 2 fuel pump and tune and easy 400 crank hp safe on stock internals. IPOS which I linked below sells the HPFP upgrade also. I say safe in terms of power as you could aim for deep into the 500 crank hp range and still have it last. For comparison if you had a 2015 328i you'd be at the limit at 350 crank for a number of reasons.
@@VehicularDIY thanks for the reply brother excited to see how this all turns out I’ll be with it for every step. In depth Videos like yours make me want to pull the trigger on my upgrades
750,000 miles behind N52 motors, we just bought an X3 MSport w/ the N20. Around town, the torque does motivate this chassis. However, the sound and vibration... Sorry BMW, BIG mistake.
PS... we got better fuel efficiency in the N52 X3 than this N20!? At 190,000 miles, the N54 was averaging 23.5mpg. The N20 w/ 70,000 miles is getting 21mpg.
nice👍
What upgrace do you recommend for a JCW f60 2023? I would like to add another 100 horsepower. most important is reliability is the family car we go to Disney with. I added a eventuri intake and hard pipe. I can't get upgrade parts information for this engine
Fastest G20 330 ran a 10.5.. I’m tryna at least get a 11.7 out the car before building motor
Nice, getting anywhere near 11s with a stock engine is impressive IMO.
Regarding the B48's, would you consider the 320i 184hp version to be reliable to tune with a stage 1 mod or will it be risky since these have the higher compression pistons compared to the ones found in the 330i ? Would be really nice to see a video regarding the different B48 versions.
I only found other engines on the MHD site, any idea if they plan to develop a B48 tune too ?
Both have the same 11:1 compression as far as I know only the 35i b48s that are in the m235i format
From what I’ve seen you can get close to 300 whp and going beyond that is risky due to the 11:1 compression pistons vs the 10.2:1 on the 330i
Whats going on bro, I have question for ignition coils do you recommend anyone particular? I have 430i 2022
No I don’t have any of those questions but is a diesel in the 3 series wagon a reliable engine?
Is the next video ready yet?
Is there a way to adjust the stock turbo to where it not peaking at low end torque and you can get more top end?
Would this turbo be applicable on a 2014 (B48) Mini Cooper S?
Hi Musa. What would be suitable replacement turbo for a F30 N20 328i ? Budget permitting I plan to when the old turbo dies ...
Hi, were you looking to try and gain a little power at the same time?
@@VehicularDIY - Yes - why not . ? Hehehe ... But do i have to sacrifice the torque at the lower rpms ?
Hey, so I have an N20, yet it keeps having a hard lurch when accelerating hard going from first to second gear. It is almost non-existent when the car is cold, but gets worse after warming up/driving. I have already changed the driveshaft, auto transmission (ZF), CV axles, and still have not fixed this problem. Any ideas? I really want to keep this BMW because it is so smooth on the highways. It is an F10. Thanks. I just cannot figure out what could be wrong with it. No engine codes come up. It also hesitates when going uphill and has a transient "drivetrain malfunction" that pops up but goes away when then going back to driving on flat road. Already checked the spark plugs and ignition coils and no difference unfortunately.
My homie actually has a 230 with a built motor and bigger turbo , he is currently making 480 on his set up
Can you confirm what was changed internally? Was is just the cast piston to forged set? Cause the rods and cam are forged , same as b58 i believe
Is a 220i b48 safe for stage 3 with bmw tuning?
Same engine b48a20t1
On m135i F40 to 128ti ?
Thanks
Can i put this IM450 on an N20 or is it for B48 only?
i really wish i had the tools & money especially, to invest & try new things.... when i grow up, i wonna be just like you happy ownership lol
So I can use this on my N20?🤔
I honestly am fine with 400hp with reliability if possible
It is a great shame Toyota refused to put a manual transmission with the BMW B48 Supra. It is lighter than B58 car. It handles better than the B58 car. All simply to protect the sales of pathethic GR86 which now suffers from oil starvation they refuse to warranty.
A B48 with a manual could be fun on a true sports car like the Supra. On my 330i I would definitely want auto as it's the daily with assisted driving. On my driveway I have two manual cars right now and one auto.
Apparently a b48 g20 manual was available in other countries😢 like for the 320d. Would have been cool to have a 6 speed 330i considering the world record for the 2.0 honda accord quarter mile time is with a manual transmission.
Does anybody make a aftermarket hybrid motor or can find a stock one to replace or improve torque with this new turbo system ?
Molto interessante! Purtroppo non è in italiano, servirebbe un doppiaggio.😅
I have a gen 1 b48, how do you not blow the pistons i know the rods and cam are b58 so it can take it
I thought the pistons heads (NOT included bearings) can only barley take 320hp, or is it the turbo?
How much can the piston heads take then?
One more question, am i right in saming the gen 1 and 2 b48 have the same transmission as the b58 aswell, the ZF8HP50 cause that thing can take up to 650 nm torque easy and safety only starts getting sketchy plus 800nm
I have to wonder tho, are the pistons, rods, crankshaft, head bolts, etc all ready for 400hp+ when it was never intended for it. Wouldn't you need to be upgrading much more to make this power reliably?
I would say yes...since this engine 2/3 the size of the b58 it should in theory make 2/3 the HP the b58 is capable of making.
