sr rwdtop -- t28 issue - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Before i did this i had a t25 fmic - afc2 was off - car smoked couple time and would have a perfect idle but would not go over 3k rpms

changed turbo- to s14 t28
now-- will rev all the way through- but wont hold a idle -
only way to keep idle is to use carb spray

any ideas?
intercooler pipeing holds air
throttle seems to be working correctly - tps-- just seems like a fuel issue - changed - fuel pressure regulator- fuel filter
could it be just a bad pump?

Check your fuel pump, wiring, and also check for vacuum leaks

oem fuel pump or aftermarket, check for boost leak
