can someone explain to me whats the difference between th RB26DETT on the gtr 33 and the 34???? do the produce the same power and performance?

basically i want to convert my r34 GTT to a RWD r34 gtr and i read in more than one place that it is possible, and i found a pretty cheap r33 gtr engine and want to know if its different than r34's engines..... i'm not an expert in skylines so if someone thinks that i'm thinking about to do something not possible please advice me

R33 and R34 GTR engines are the same.

Both RB26DETT, but there would have been a few refinements for the R34. (Tuning wise)

Both R33 and R34 GTR's came with the standard RB26 and the N1 Editions came with N1 engines.

...and thus, the refinements lead to more torque from lower down in the rev range.

thanks guys for the replies....so what you are saying is that if i put the rb26 from the r33 gtr on my GTT and tune it properly it should perform exactly just as an rb26 from r34?

did i get that right?

nearly = not quite = just about = virtually = so close = Hmmmmm = or as Maxwell Smart says, "missed by that much"!

AND ONLY IN A STRAIGHT LINE WITH THAT GT-T RUNNING GEAR (since you asked about performance too).

At the end of the day H B, if you're getting a great deal with an R33 RB26DETT motor, I wouldn't be put off from going ahead with the conversion.

And if you really want to boost your torque (since your engine is out already), budget for a couple of TE25/30s or HKS RS turbos too.

All the best with it! But don't forget your stoppers!

Agreed. It was the package as a whole that was more upgraded than the engine and gearbox. While there are tuning differences, and with that, power differences between the r32, r33, and r34 model engines, they are essentially the same engine.

That's why I should sell my 33 gtst and buy a 32 gtr now instead of pissing away any more money, and starting with the better package. But I'm an idiot.

Realistically, age and km's are more important than the series of gtr the engine came from. Unless it's a Nur. Or has been rebuilt. Or particularly strong or weak due to factory tolerances. Or if you buy the engine on a Tuesday. you get the drift......

there are differences between motors........

the most obvious difference is the Rocker Cover on the Engine... R34 being Red paint & R33 just plain black base colour.

they peform slightly different power in tuning.

The R33 RB26 is closer to the R34's than it was with the early R32 Rb26's, as the Crankshaft had a slight difference in size as well as it causing problems with the oil pump.

The head on the R34 has been improved after the R33....

The R34 Rb26dett has a Aluminium Inlet Plenum Chamber, where the R33 has a plastic one.

The crank angle sensor on the R34 is black, where the R33 is metalic.

there probably are more little differences here and there

huh? The inlet plenums are exactly the same! The real differences between the R32/33 and R34 RB26s is as you mentioned the R34 runs a different CAS which means you need R34 specific cams Main difference is the R34 runs far better ceramic ball bearing turbos, giving the engine better torque characteristics and ultimately a few more kws when tuned up with an ecu and exhaust.

well ive never had a r33..

the colour is different

in that case the colour is different

with the R34 being aluminium and the R33 black

    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
    • That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope!
