. Anyway Im kind of in uncharted turf with the s14. The wiring looks like a birds nest and i plan on putting a wiring specialties harness on it asap to clean it up . But driving it home yesterday it seemes to hesitate when i get in the throttle. To me it seems like either the vehicle is starving for fuel or their is major boost lag. Its also experiencing fuel cut when the boost jumps past 10psi. The kid who built the car put a z32 fuel filter and a z32 fuel pump with stock injectors and a z32 maf as well as a safc 2. The ECU was "supposedly" rom tuned but who knows if thats true. The setup he has now is a T04e turbo with a 38mm external waste gate that supposedly has a 16 psi spring but I watched the boost jump past 20 more than once so who knows at this point what spring is in it. I plan on using the car for a run around- weekend at the track car so it has to stay reliable. Whats your guys thoughts on what fuel system upgrades if any that i need to make? As far as engine management Im not much of a fan of safc's so Im going to be looking into getting Nistune asap. Any advice is greatly appreciated! Also are the t04e turbos know to be laggy on a stock rb? Thanks again every one.
