Factory redline?

[replicate]

Whats the factory redline/cutoff for an RB20DET cefiro? Mine originally had an RB20E so i don't think the gauge is correct.

[sky80]

get a RSM or just a big tacho i need one too, let's get a group buy

[summoner]

just let it go till limiter

my RB20's i had the limiter set to 8500 without problems and i'd shift around 8200

[replicate]

8500!!

is that with a stock engine?

Whats the factory cutoff?

This is all new to me as i've never had an RB before.

[summoner]

Yeh thats on a stock engine but I wouldnt rev it much harder than that though

[sky80]

i wouldnt even take it that high...rather keep the block in one peice...i would take a normal rb up to 7 though

[summoner]

what you mean keep it in 1 peice? will go that high easy without over stressing the engine. Only failures i have with constant thrashing was 2 injectors because didnt service them when put int(was running 550cc RX7 injectors), besides that the engine ran smooth the whole time.

Each to their own though im just talking from personal experiance. from an oversquare rev happy engine more rpm the better

To my knowledge (and what i have set my red line cut out on my ECU) it is 7850rpm

This is more than enough revs, you mainly have to worry about still being in torque curve when u shift to the next gear, and you should well be if you shift at this point... anymore than that (over 8000rpm) i think is a bit dangerous

[sky80]

one peice as in these engine are getting old, and i dont wanna be doing 8000rpm and have the oil pump/water pump/belts/etc give up on me. i loved reving my r32 aswell, but there just didnt seemed to be much point after 7k, at most 7500...what ever floats your boat buddy

[geno8r]

Yeh on the r33 Gtst mines 7000... If I got a power FC i'd set rev limit to 7500 - or 8000. Wish i had an r34 GTR, seen the Japanese racers in'em they stay on 7000 - 9000 the whole time !!!!

[summoner]

Geno we are talking about RB20's not RB25's BIG differance there in revability

Not to mention RB20's share the same valve train as the RB26. RB25 is kind of a bastard child engine

mine is set at 9, shift at 8500
