In this episode of Technically Speaking we take a closer look at what is arguably Nissan's finest engine series - the mighty RB. Their popularity has been on a continual upward spiral since the mid 1990s but the RBs are not without their flaws. That's why we've invited a special guest Andrew Hawkins from Motive Video to our studio to cover the DOs and DON'Ts of an RB build. Covered in this video: • RB series history • Engine Overview: ua-cam.com/video/TS3fFLg2QfU/v-deo.html • Tuning Options: ua-cam.com/video/TS3fFLg2QfU/v-deo.html • DOs and DON'Ts: ua-cam.com/video/TS3fFLg2QfU/v-deo.html Tell us what engine you would like us to do next in the comments section!
Agreed, was going to post same thing - good presenter! Edit: 2:07 "Still powered by the RB26... (THWACK!!!)" great job man enjoyed hearing about this engine
Many RB's lives were saved just by watching this video. The Aussie car content is awesome these days Motive TV, Street machine and haltech heroes are really doing an awesome job keep it up.
RawCkeT god I’d take any car over an r35 they disgusted the Nissan lineage with that, I still respect it but like, man they went in such an opposite direction
nahh..used to be 2jz lover but then my heart fell towards rb26..sorry 2jz...2jz is great but the kind of energy and promptness rb has, 2jz lacks there!!
Nice video but why does everyone who does a video on skylines forget that the R33 was the first mainstream production road car (Jaguar XJ220 aside) to do the Nurburgring in less than 8 mins. 7.59 by Dirk Schoysman.
People do forget when they are building RB's, to put a integrated main-cap brace into it to avoid the block cracking, and they just crank up more power and end up dumbfounded when it inevitably cracks from load.
Aussie car channels are killing it lately with the awesome content thanks dudes. Me thinks the knowledge you guys bring forth helps save the lives of many an RB.
Thank you for mentioning the Australia Touring Car Series, most other videos I've watched on UA-cam don't mention the ATCC when talking about the R32 "Godzilla" GTR. More than the Japanese series it was in the Australian series and it's domination against the best from Australia and Europe where the GTR really made it's mark internationally, and eventually lead to the demise of Group A Touring Cars. And of course, it received it's name "Godzilla" from Down Under as well.
Hey brokosky, huge fan of you and the mates from MCM.. Love how you always, and maybe not even realizing it, have the ability too dumb down the information for simple folks to understand. You're very easy to listen to, and I hope your channel the best of success. It's great having all this knowledge at my finger tips at anytime.
A few similarities with the Ford Cleveland V8s issues. Core shift, split bores, pumping too much oil up top etc, an a lot of the same remedies. Really interesting
CA18DET?? Dont you mean Rb20DET with two cylinders shaved off?. Nissan should have made more CA18s and kept producing FJ20s instead of SR20det oh i said it. Sr20: give me all your money "Pulls out knife" FJ20: thats not a knife. "Pulls samurai sword from sheath" FJ20: Now this is a Real knife.
@@Suprastar77 Nissan had to ditch the CA18 to make a more cost efficient and less pollutant engine. Otherwise they probably would have kept making them up until the mid 2000's
My 34GTR split its oil pump. Spoke to my tuner/engine builder and turns out it split due to the pickup in the sump running dry around the hairpins on the mountains. The pump had burn marks and a cracked gear. Needless to say, during my 2.8 stroker build, i decided to get my block strengthend with the appropriate oil gallery + oil return mods, baffled 9l sump with a Nitto billet oil pump AND a Greddy oil cooler. If you are in the same boat as me and are building a new engine, id advise you always protect your investment and eliminate any potential risk and invest in an good pump and deep baffled sump.
Just to get an RB here in the States, it has to be imported from Japan, and it's pretty pricey. That bottom end brace is very much the future of high performance engine block building. Love the series and history.
I have a 1991 R32 Series II with a long nose crank. I bought it 2 years ago and shipped it to Texas. It had the factory boost restrictor on it and was stock except for intakes and full exhaust. I removed the boost restrictor a year ago for a little extra fun. The compression is excellent between 170 and 185 on all cylinders. I'm planning on replacing the stock turbos, upgrading the fuel system a little, and turning up to boost to support around 400whp....It has 123,000 MILES though, of which I've put 30K on. I'm hoping it'll hold the power without issue as I'm not chasing 'big power'. WISH ME LUCK!
500kw on stock bottom end.......lol, my block was worn out with 380kw in no time, circuit work will do that. The crank flexes and wears bearing and ultimately the block. RB engine harmonics are also a serious issue, this is why oil pumps break and crank noses break, it isn't just RB's, all inline 6's suffer from poor secondary vibration issues. This point is hardly ever mentioned with inline 6's and is one of its biggest problems and understand this is important and how it can wreak havoc if not mitigated and checked. My RB 28 broke after a few years of racing time attack too, the crank nose broke, this was on a full HKS built engine with nearly everything done to it for reliability, the secondary imbalances catch up with you in the end. Saying that drag cars will crack the block before a track car is laughable, the loads on a circuit are continuous for up to 20 minutes at a time and are experiencing harmonic imbalances for long periods of time. For me the RB is not really an engine I like that much anymore, they are very heavy, too long for packaging in a lot of cars, and In fact inline 6's are not really a good engine for circuit work or making a circuit car fast all together. The RB was a good engine overall, it achieved great things, but race cars have evolved significantly since the Bathurst. Drag racing is one thing, but the balance of a circuit car is a whole different ball game. One of the biggest issues when approaching 400kw and over is the use of twin turbos. I ran 500kwatw with GTX2863's, they were fantastic for response, annihilated any single turbo, even the EFR Borg series, but it came at a high cost, engine heat. It isn't from radiant heat issues as much as it is form having small rear housings so the exhaust can't get out as well, and the increase boost levels to compensate for reduced LPM flow rates of twin turbos. I was running 33psi and the reason why you can use a single turbo at 22-24 psi and achieve the same power level is because the turbo has a higher capacity (LPM), and when the inlet valve opens, it does not have such a drastic pressure drop as the piston draws downward (It hurts even more when using higher overlap cams), sadly overcompensating for lower flow rates, means increasing turbo pressure and thus inducing a lot of extra heat from increased pressures, this is by far the most important reason for changing to a single turbo over anything else. If doing circuit work I can't stress enough for the use of an engine oil coolers and competition radiators and the best inter-cooler you can find, at-least for twin turbos RB's, but the selection of a good single turbo like an EFR8374 or 9180 would be one of the first things to consider if looking at keeping it nice and cool for a circuit car. A steel crank, or crank girdle is a must upgrade for pushing a track car to these levels for long term reliability. The blocks crack because of weak cranks first, then harmonics second, crank girdles are great keeping stock cranks straight, but realistically a billet crank is the answer (maybe a girdle as well if you want bullet proof). Secondary harmonics ? Well that is a very hard thing to chase and cure and unless you have access to lots of vibrational analysis gear, it is a little bit of calculated guess work. Fluid viscous dampers can def help over vulcanized rubber variants and looking at lightened flywheels and clutch assemblies also helps a lot too, that is about all we can do.
So you are saying it would be well worth the $2500 to install an Integrated Main Cap Brace like the one presented near the end of this video? Most of the issues you mentioned would be eliminated with a brace, since it eliminates the twisting that cause most of the failures you mentioned, or am I wrong in my thinking?
@@JJ_ExMachina no you are definitely right about the brace from my experience, but if you had the billet crank and brace it would be very strong indeed for many years. IMO, crank brace girdles are very underrated, they are integral at keeping long engines very rigid and do improve engine rigidity quite well from what I have seen.
Question, in terms of engine heat using water injection or water meth injection , would it not help the heat situation by cooling intake temps drastically ?
always enjoying your videos tuning fork. Cant wait for the next lesson on engines from you guys. If you would do the nissan vq series that would be amazing.
Nissan FJ20, Nissan CA18, Mazda 13B rotory, Toyota 4AGE, Subaru EJ20 and EJ25 and difference between open and closed decks as i just bought a gc8 and am very frustrated with it. Yamaha Banshee/rz350 2 stroke engine plz.
Scotty you could have tried saying ,"And I love that you have brought me this present " and try to grab on to that brace , the look on his face would have been funny. Great vid & Cheers from NZ
Oh nice thanks everyone!! That makes sense then was thinking it was some combination of both... I'm in the states and where I'm at in the states the RB is almost non existent. It's a shame too I've always wanted to play with a fuel injected inline 6.
@@brandonb8543 plenty of rb cars down in FL where I live along with my own rb powered car. Give it some time cuz we're getting more skylines here as time goes on so you'll start to see more rbs floating around in the future.
Oh joy, the comments are like: Supra is better! GT-R is better! JZ is better! RB is better! When it comes down to engineering, the 2JZ is simply better built. Bigger displacement, stronger parts, more tuning capabilities, can handle more power on stock parts. It's barely even a contest. But honestly it's all about preferences, and I like them both, though I like the way the MkIV Supra looks over how the R32, R33, and R34 looks.
If Nissan would keep using this engine to replace all the lame boring fuel saving 4 cylinder engines, I'd want their cars for more than just its GTR cars
those are not cheap to made....company need money... that RB is getting outdated... it just good for power.. try to drive it fast and the fuel gone like no tomorrow...
hi, wasn't the RB engine an outsourced replacement for the old Holden Engine in the australian commodores....the RB30ET from the VL Turbo commodore in the mid 1980's?
R32 actually had around 300+ hp out the factory. They just couldn't reveal actual hp because of the gentleman's agreement in Japan amongst car manufacturers.
The Holden VL calis turbo was such an amazing car. It looked good & was fast. It was so damn good , the Australian engineers had to lower the engine below the radiator to ensure it would over heat & warp the alloy head to ensure it needed repairs to continue Holden's reputation of making junk as part of there company policy , in which to this day was responsible for customers leaving the brand to find better products.
I would honestly love to see a video on Subaru's FA20. I know that it's not special or legendary but It'd be great to know its short comings and how to best upgrade it.
Is the "core shift" a result of casting I am assuming? Where the corebox inside of the mold used for casting actually drifts within the mold creating the differing dimensions?
nice one scotty, im an RB guy but about to go SR, i know it hurts... all the way from Tochigi where the RB was made, i think about 20 minutes away from where i am lol, back then it was reference as the Million Dollar Man beating up the Ozzy Joe Blow, special shout out to MOTIVE VIDEO YT channel for all and everything you need to know about the RB and on that note SAMMIT YT RB guy living in Japan that drifted and filmed with Adam LZ and the DK of S15
Problem with the oil pump gears is the stupid drive nissan used because it is cheap to machine. It makes the gear thin in 2 spots and when a crack forms there say bye bye to your engine. 2JZ has a proper spline on the oil pump drive..You don't know how many people want to punch that person responsible for this stupid decision. Same thing on the CA18 and SR20 oil pump..
Any one put RB26 head on RB25det block? I prefer the smaller stroke to bore ratio. A custom Billet RB32-34det that has same stroke/bore ratio of RB25, or even RB20 would be NUTS! Ever heard an RB25det with top shelf dump pipe and top spec, professionally configured full exhaust system? Beats the shit outta 99% of RB26’s I say we start a company that manufactures the turbo barra engine and exports them to foreign markets for reasonable price. Be hard to meet demand.... Imagine aftermarket sector for that engine if USA got their hands on it. They would be in EVERYTHING from skylines to 4WD’s to drift cars to boats even. Conversion kits and parts would be cheap as dirt. Who’s in? Lol
The first car I owned free and clear was a '92 Laurel (C33) Medalist Club S with the RB25... loved that car. It got me an $800 speeding ticket and an all-day interrogation with NCIS and local police... but it was worth it. I was delighted to discover the Q50 I bought a few years ago is the current Skyline. Infiniti model naming conventions are stupid... so while on vacation in the motherland, I went to the Prince dealer and ordered the correct badging. I have dreams of finding a good President Sovereign, keeping the exterior/interior as mint as possible but boosting the V8 and some bolt-ons. Possibly swapping to a more recent V8 (direct injection 5.6L sounds great if I have unlimited budget).
I am loving this segment, what about doing a Technically speaking on inline 5’s, Audi’s 5cylinder, Ford/Volvo’s inline 5 turbo found in the FocusST225-XR5 ?
@@networkengineer4405 Not all Brits use metric for everything you know. Most of us use ft-lbs, MPH and miles for instance. Some metric scales just make more sense though like C vs F. Fahrenheit is honestly a ridiculous scale and inches and yards are pretty much useless when any level of accuracy is necessary.
@@networkengineer4405 You fucking moron! its not nothing to do with australia and england. And if you are going to use that useless information the UK still uses imperial measurements like the backwards country of USA. Australia started using it in the early 1970's.
Really check out the Motive Video channel, they have SO much stuff on this. *If* I remember correctly, Platinum make a billet steel gear set for the stuck short nose pump that doesn't increase flow, but should be bullet proof.
I think andrew has a long nose crank. That's the only reason I asked. But PRP doesn't make a gear that I'm aware of. I know there's other's, just wanted to know if its worth messing with or just running the stock gear until it let's go. Everyone keeps saying buy a nitto collar, but that does me no good because I'd have to take the bottom end apart for machine work.
I've been on the rev limiter for 5 years str8 on my s1 rb25 with original standard oil pump and short crank. Yes it can become an issue but it's not as fragile as hit limiter one time and it'll pop. Ppl drift skylines, laurels, cefiros with short cranks oe pumps and have no issues all the time. If you don't want to extend the collar then you can do steel gears but I'm still not sure if you can get away with them without pulling the crank.
Oil pump gear width is NOT the issue. The issue is gap between the oil pump gear and the crank nose. There's too much lash, and when the engine bounce of the rev limiter, the crank will crack the pump gear.
RB's are 'great' due to the development they have received and the popularity of straight sixes for aftermarket purposes here. There is nothing exceptional about the basic engine, just like the SR experience identifies the weaknesses, demand leads to aftermarket fixes and parts. It would be interesting to compare RB's with their euro counterparts.
@@Enthropical_Thunder I'm a jz boy but also a qualified mechanic that runs his own workshop RB motors have multiple underlying issues as does jz but jz's are much less of a issue then the rb's.

Nissan FJ20, Nissan CA18, Mazda 13B rotory, Toyota 4AGE, Subaru EJ20 and EJ25 and difference between open and closed decks as i just bought a gc8 and am very frustrated with it. Yamaha Banshee/rz350 2 stroke engine plz.
My dream car is the 400R
I want it so bad
R33 gang
Scotty you could have tried saying ,"And I love that you have brought me this present " and try to grab on to that brace , the look on his face would have been funny. Great vid & Cheers from NZ
The thought did cross his mind LOL he found it hard to let it go after the shoot!
Because it came from the most successful sportscar bloodline in Japanese motorsports history.
I could listen to scotty talk all day, it’s therapeutic
Great video.. love the RB series engine ❤
my opinion, the BEST sounding engine
Scotty please cover the 2JZ-GTE, great info keep the videos coming
Gay ass engine in a gay ass car
@@dustinchen go fuck yourself, you homophobic piece of shit.
Man I respect this guys knowledge on RBs.
Great vid my guy! Just subscribed. Btw, what’s the name of the intro song?
Just rebuilding my rb with a short nose crank and well safe to say I started rebuilding it 😂 going dry sump now so I don’t have to worry about that
Could of access added crank collar extension too
Was going to do that but end of the day I have the money and figured why risk my fresh motor I have spent 10s of thousands on
4g63 please!
Can you do one on 3rzfe engines which have been turbo charged
Awesome episode tunning fork, please do one on 1j, 2j and 1.5j.
Please excuse my ignorance but what the hell is a 1.5j?
@@brandonb8543 2JZGE bottom end with a 1JZGTE head
@@brandonb8543 its not an official engine factory buily. But some people use a 1j head and put it on a 2j bottom end
Oh nice thanks everyone!! That makes sense then was thinking it was some combination of both... I'm in the states and where I'm at in the states the RB is almost non existent. It's a shame too I've always wanted to play with a fuel injected inline 6.
@@brandonb8543 plenty of rb cars down in FL where I live along with my own rb powered car. Give it some time cuz we're getting more skylines here as time goes on so you'll start to see more rbs floating around in the future.
Oh joy, the comments are like: Supra is better! GT-R is better! JZ is better! RB is better!
When it comes down to engineering, the 2JZ is simply better built. Bigger displacement, stronger parts, more tuning capabilities, can handle more power on stock parts. It's barely even a contest.
But honestly it's all about preferences, and I like them both, though I like the way the MkIV Supra looks over how the R32, R33, and R34 looks.
All amazing engines and cars ,although I'm also biased towards supras
What a fantastic video.
I want a RB26DETT. Don't care what I put it in, I just want one
You can also upgrade to R8 aka VAG coils, much cheaper for the same performance and available worldwide unlike R35 ones.
I grew up in Texas as a kid and I fell in love with the Skyline from Gran Turismo back in 92' or 93. Way before Fast and Furious. :(
Gran turismo wasnt a game in 1992 you weirdo
Built by Japanese engineering gods!
not really some still broken... after all it was just to made around 280hp on first place....
The brace is also used stock in Mitsubishi 4g engine
What's so special about RB you ask? When u put the & symbol between them, they make good soul rocking, love making music 😁
I’ve got a RB30E in my GQ Patrol, what a wonder combination 🙌🏻
If Nissan would keep using this engine to replace all the lame boring fuel saving 4 cylinder engines, I'd want their cars for more than just its GTR cars
those are not cheap to made....company need money... that RB is getting outdated... it just good for power.. try to drive it fast and the fuel gone like no tomorrow...
campkira are u dyslexic
@@campkira Got to pay for their swindeling CEO's fines and legal bills somehow!
hi, wasn't the RB engine an outsourced replacement for the old Holden Engine in the australian commodores....the RB30ET from the VL Turbo commodore in the mid 1980's?
Yes, Scott covers that exact topic at around 4:20.
R32 actually had around 300+ hp out the factory. They just couldn't reveal actual hp because of the gentleman's agreement in Japan amongst car manufacturers.
The Holden VL calis turbo was such an amazing car. It looked good & was fast. It was so damn good , the Australian engineers had to lower the engine below the radiator to ensure it would over heat & warp the alloy head to ensure it needed repairs to continue Holden's reputation of making junk as part of there company policy , in which to this day was responsible for customers leaving the brand to find better products.
When tuning fork speaks. I listen. He's super smaht
I would honestly love to see a video on Subaru's FA20. I know that it's not special or legendary but It'd be great to know its short comings and how to best upgrade it.
“GD-Ahh”
I see Tuning Fork I thumbs up. Simple as that.
I was going to say something "clever " about the gdr, but thats already been played out.
Nooo... c'mon, there should be more GDR cleverness out there, surely?
Is the "core shift" a result of casting I am assuming? Where the corebox inside of the mold used for casting actually drifts within the mold creating the differing dimensions?
Everytime he says RB's, I want to eat a shaved beef and cheese sauce sandwich on an onion bun.
nice one scotty, im an RB guy but about to go SR, i know it hurts... all the way from Tochigi where the RB was made, i think about 20 minutes away from where i am lol, back then it was reference as the Million Dollar Man beating up the Ozzy Joe Blow, special shout out to MOTIVE VIDEO YT channel for all and everything you need to know about the RB and on that note SAMMIT YT RB guy living in Japan that drifted and filmed with Adam LZ and the DK of S15
I'm all about the rbs on my channel aswell 🤗
Problem with the oil pump gears is the stupid drive nissan used because it is cheap to machine. It makes the gear thin in 2 spots and when a crack forms there say bye bye to your engine. 2JZ has a proper spline on the oil pump drive..You don't know how many people want to punch that person responsible for this stupid decision. Same thing on the CA18 and SR20 oil pump..
St0RM33 You must be some sort of genius bro.
True. Add the block cracking because of the AWD setup on higher HP and that makes it worse
I and the r32 have the same birth year and month, no wonder its my favorite of all gtr's
Any one put RB26 head on RB25det block? I prefer the smaller stroke to bore ratio. A custom Billet RB32-34det that has same stroke/bore ratio of RB25, or even RB20 would be NUTS! Ever heard an RB25det with top shelf dump pipe and top spec, professionally configured full exhaust system?
Beats the shit outta 99% of RB26’s
I say we start a company that manufactures the turbo barra engine and exports them to foreign markets for reasonable price. Be hard to meet demand....
Imagine aftermarket sector for that engine if USA got their hands on it. They would be in EVERYTHING from skylines to 4WD’s to drift cars to boats even. Conversion kits and parts would be cheap as dirt. Who’s in? Lol
The first car I owned free and clear was a '92 Laurel (C33) Medalist Club S with the RB25... loved that car. It got me an $800 speeding ticket and an all-day interrogation with NCIS and local police... but it was worth it.
I was delighted to discover the Q50 I bought a few years ago is the current Skyline. Infiniti model naming conventions are stupid... so while on vacation in the motherland, I went to the Prince dealer and ordered the correct badging.
I have dreams of finding a good President Sovereign, keeping the exterior/interior as mint as possible but boosting the V8 and some bolt-ons. Possibly swapping to a more recent V8 (direct injection 5.6L sounds great if I have unlimited budget).
We need full story about police and NCIS
We do?

I am loving this segment, what about doing a Technically speaking on inline 5’s, Audi’s 5cylinder, Ford/Volvo’s inline 5 turbo found in the FocusST225-XR5 ?
We are in Australia use METRIC measurements!! we use 0-100km/hr, Kilowatts and Neuton Metres not hp and ft-lbs and 0-60pmh we are not american.
@@networkengineer4405 Not all Brits use metric for everything you know. Most of us use ft-lbs, MPH and miles for instance. Some metric scales just make more sense though like C vs F. Fahrenheit is honestly a ridiculous scale and inches and yards are pretty much useless when any level of accuracy is necessary.
I am sorry for Vila Xaya's Comment I promise all Americans are not asshole's like that. God bless you brother.
God damn right you're not Americans.
@@networkengineer4405 You fucking moron! its not nothing to do with australia and england. And if you are going to use that useless information the UK still uses imperial measurements like the backwards country of USA. Australia started using it in the early 1970's.
@@jasonswift7098 yeah fuck the metric system! Fahrenheit for life!!!! Fuck Yeah!!! Are you listening to yourselves Hahahaha, fucking losers.
Question. So I've got a 1990 GTR. So it has the short nose crank. If I buy new oil pump gears. will that buy me more time??
Really check out the Motive Video channel, they have SO much stuff on this. *If* I remember correctly, Platinum make a billet steel gear set for the stuck short nose pump that doesn't increase flow, but should be bullet proof.
I think andrew has a long nose crank. That's the only reason I asked. But PRP doesn't make a gear that I'm aware of. I know there's other's, just wanted to know if its worth messing with or just running the stock gear until it let's go. Everyone keeps saying buy a nitto collar, but that does me no good because I'd have to take the bottom end apart for machine work.
It's the drive on the crank that is more the problem
I've been on the rev limiter for 5 years str8 on my s1 rb25 with original standard oil pump and short crank. Yes it can become an issue but it's not as fragile as hit limiter one time and it'll pop. Ppl drift skylines, laurels, cefiros with short cranks oe pumps and have no issues all the time. If you don't want to extend the collar then you can do steel gears but I'm still not sure if you can get away with them without pulling the crank.
@@clutchkickpj693 If the 25 is in good condition to start with and tuned properly it takes a hell beating
I love the GD-Ahh engine
Oil pump gear width is NOT the issue. The issue is gap between the oil pump gear and the crank nose. There's too much lash, and when the engine bounce of the rev limiter, the crank will crack the pump gear.
YOU : RB
UA-cam : *BARBIE*
Gotta ask, whats with the Oklahoma license plate on the shelf? Kind of a random thing to have in an Aussie shop.
A souvenir from a trip to visit the Street Outlaws in OK.
@@haltech i kind of thought that might be the case, MWSC is only about a mile from my house
Your name is TUNING FORK! not Scott! Great video
Oh, sorry, my mistake.
RB's are 'great' due to the development they have received and the popularity of straight sixes for aftermarket purposes here. There is nothing exceptional about the basic engine, just like the SR experience identifies the weaknesses, demand leads to aftermarket fixes and parts. It would be interesting to compare RB's with their euro counterparts.
Ah, remember when Nissan didn't engineer utter crap, or just re-hash the few good models year after year with minor changes for a decade or more?
Great video, super informative. More RB / GTR content please! Looking forward to the Crank & Cam triggers video and how it works with Haltech.
I'll tell you what's so special about the RB, absolutely bloody nothing.
That's a moronic answer ;D.
@@Enthropical_Thunder the honest answer*
@@tcollogan
No, since it is an outstanding engine. The N54 is an even more outstanding engine and the 2jz is probably the most durable of them all.
@@Enthropical_Thunder I'm a jz boy but also a qualified mechanic that runs his own workshop RB motors have multiple underlying issues as does jz but jz's are much less of a issue then the rb's.
@@tcollogan Long term, every ICE in existence has underlying issues.
A friend had a r34 gtr single turbo, it was tuned making 800 hp. That bastard was fast af. Also the awd setup looks like what BMW uses.
