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

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.

      Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By GTSBoy · Posted

      No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.

      You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
