I highly doubt you can make ~1300hp with the amount of airflow through a 63mm aperture.. someone do the maths and tell me it's true before I believe it.
rb26s13: what has been covered many times? there are two questions, a main and a secondary. Please be specific or piss off
Lastly, I have an RB30DET in an R32 with a GT35R to go on (for those that don't know) so I don't care about response/power/etc, I need to do this as it is the only way the piping will work with my setup. I have seen the RIPS and plazmaman items, aswell as some custom jobs from people on the forums, but am reluctant to fork out for a new item at the prices they are.
Maybe I shouldn't have asked about the throttle body.. my mechanic said I can't use the RB26 throttlebodies (likely due to wiring etc) and TBH I really can't be assed trying to get them to work.
To cut it short, has anyone fitted an rb26 plenum to an rb20/25 (doesn't matter which as the required mods would be practically the same), with or without throttle bodies.
Is it safer than an ebay job from the states?
I have vaguely gathered that 26 plenums can run one cylinder slightly lean but as it's a widely known fact tuners compensate for it.. is this correct?
