how can you tell?

[leez32]

hey guys can any of you tell me how to tell the difference at a qiuck glans (if any) between a rb26 from a r32 and r34? thanx

The R34 RB26 will have a black newer style Cam angle sensor on the front of the timing cover. The R32 RB26 will have the older Mitsubishi style silver Cam angle sensor on the front. Also, usually, R32 RB26s have black valve covers and R34 RB26s have red valve covers, but of course color could have been changed at one point in the past.

ok i will be on the look out for that when purchasing a rb26,altho ive heard that r34's rb26 are very hard to come by...thanx for the info guys

What's the reason for wanting an R34 26? There is virtually no difference besides miles and a much larger price difference.

[leez32]

well i read on here that the rb26's from the r32 and r33's have some crank coller probs,do you know anything about that?,cos im not sure

[TimTurboZ]

CarlH could confirm more and I'm sure others but it was shown that even some earlier R34 RB's still have the crank issue...

Im not saying that the crank collar issue isnt legitimate but.... There are alot of high HP car that never have an issue with the smaller collar. Most people can buy an RB, mod it with larger turbos and make more power on a motor with a OLD crank collar and never see an issue. Yes the contact section for the oil drive is significantly smaller but I have personally only ever seen talk about the collar, no one from what I have searched has ever posted photos of a failed collar. (which I know, "just because Ive never seen it, doesnt mean it doesnt exists") Even with the echoes of crank collar failures, Ive personally met people who thrash on the 25's and 26's with the smaller collar all day long at local drift events.

It is a high RPM issue from what I can tell, like above 8k. Which isnt so good for a stock motor drifting anyway so I recommend get it fixed if your building the motor or intended to build a higher revving motor, otherwise its not worth initially stressing over.

Just my opinion, The collar talk has always annoyed me, take from it what you want.

As others have mentioned... the crank collar issues shouldn't divert you to the R34 series motor alone. Even at the point of failure, the crank collar fix will cost you approx $200 installed. When a R34 motor will easily cost you over two times the cost of a R32 RB26. Late model R33 RB26 motors have collar fixes as well as the R34 RB26's. Some R34 RB25 Neo motors have long collars... most don't.

ok so the crank collar issue is not really a big prob,well only at 8k+ rpm then maybe,if i had to fix it before any probs arise what can i do? btw thanx a mill guy"s i really appreciate it

Here is my take on the crank collar issue. If your tearing your motor down anyways might as well do it.. If not and not making crazy power screw it, most likely wont see any issues. If you plan to make 500-600+ hp and plan to beat it a bit, I'd be considering it (especially if its a high mileage motor - more miles = more likely to be more worn) I'd never spend the coin on a r34 motor just to have an extended drive... much more practical to just modify the r32's or r33's and cheaper.

ok ive decided then,i will get a r32 or r33 rb26 and (save alot of $$$) thanx to u guys im not looking for crazy power maybe just 300-350 rwhp ofcourse want to use it as a everyday driver or so,is there anything to look out for when purchasing a rb26 the (condition) of the motor? one maybe cleaner then the other but that don't mean its better on the inside
