My r33 s1 rb25det, has a rev limiter of 7100rpm. secondly i dont see how if tacho read 7000/7100 is only reving to 6700-6800
also saying that if u shif up you will end up going faster isnt as ture as it sounds. the fact of the matter if u shift at the limiter would will be futher along in the next gear. i have drag many mid mod r33, (exhuast,fmic,airfilter the normal) and i have a Rb20 turbo on my car making farless as quick as a normal r33 would be with my mods and i can beat, keep up with them due to them shortshifting and me pushing all the way to the limiter (when i say shortshifting i mean they shift around 5500,6000rpm)
just my 2cents
dan22, have u block up the pipe in which the stock bov would plum back into the turbo intake? also try adjusting the screw on the bov; i had a hks bov for along time on my car with no stall problem
