Hi all. Im new to the honda engine building so heres my problem. I recently rebuild engine in 92 prelude. Its a h23. I put forged rods and pistons in it and sleeved the block. Im running a walbro 255 right now witch works fine. Im planning on turboing car in near future . Im using a Holley FPR adjustable from 15psi to 65 psi. OBX fuel rail, with 450cc blue top injectors. The regulator will not reduce pressure to injectors to where car will idle smooth. Just keeps fauling plugs out. Now I did find that 1 injector is clogged or just not working. I know this doesnt help but is this a major part of the problem. My main goals are to have about 350-400whp out of car. Do I need a fpr, do I need aftermarket rail or will stock work. Hellllllllllpppppp.

What rail shoul I run, what fpr should I run, What size injectors should I go with
Any input would be greatly appreciated.

 

youre going to need to get a tune to handle those bigger injectors.. im running 450cc right now, but my computer is chipped. you'll need to do the same so you stop fouling those plugs

 

set the FP to stock and tell hondata (or wotever your using) the size off your new injectors, it will adjust for the rest off it. untill you get a proper tune anyway
