Boost Cut

Post by **NISMO_RB25** » Thu Feb 12, 2004 9:32 am

I know a lot of you guys have already started upping the boost, or getting bigger turbos. Does the RB have a fuel cut at certain boost level? I have a Fuel cut defender for my FC3S, but I haven't seen any one mention needing one for the RB?

I would like to run 10PSI on stock RB25 turbo for now, and was wondering other than a boost controler and injectors, if anything else is really necessary.

YES THERE IS.... ITS SET AT 14.7PSI, ALOT OF BOOST CONTROLLERS HAVE A BOOST CUT DENFENDER BUILT IN SO I THINK YOU SHOULD BE FINE.

at about 17psi the stock MAF is maxed out. so if you hit that you get a fuel cut.

....sort of wish i didnt know that :oface

Thanks guys! I plan on staying at 10PSI for a while and focusing on the suspension. Big boost will come later
