I am planning on running E85 soon and was woundering if stock FPR and Fuel Rail will work? I am running 1000cc's and 255lph.

 

typical vague question....... depends on the power level you are trying to achieve, but I would definately get a 1:1 Adj Fuel Press Reg.

 

i run a jdm ITR Turbo with an sc34..looing to make around 315

you will be fine, get a FPR though

 

Actually the stock FPR will be fine, just get a gauge if anything.

The reason it would work - with the same size pump, you bypass ~30% LESS fuel through the FPR. Given that a 255HP on a stock FPR only bumps if up ~10-15psi (~30% more), it should probably stay around stock if 30% more fuel is going through the injectors instead. Worst case you get a few extra PSI of fuel at idle, but you have to retune the entire map anyways.

yea, but I bet his high compression JDM ITR makes more than 315whp with that SC34 and E85, so why not just add the FPR, its not like it costs $400
