If i was to run a CT20B at 17psi with a spearco intercooler, TKO DP and 3" exhaust with a K&N filter of course, is the stock fuel system still sufficent or should i upgrade?

If so what do i need to do? do i need to do the whole system?

Thanks

you can run more than 17 psi with a spearco i/c and a ct20b. i dont no if u have to upgrade the fuel or not. i would amagine so. if so i would go with 550cc injectors with a supra fuel pump and fuel presure regulater and go and get it dyno tuned for best results.

depends on how much power your making if your over 300hp then everywere says you need to upgrade and a popular one is just drilling it out to 450cc injectors. but we you chose works

well if i was to do it i'd get supra injectors, ats ported fuel rail, and a walbro 255lb/hr pump and a aeromotive fuel press. regulator but i reall dont want more than 300whp and i dont want to have to buy a programmable ECU cause no one around me knows how to tune it, does anyone know of a good tuner in the NY,NJ, Penn. area ?

I suspect the OEM fuel would be sufficient for 17 psi out of a CT20B.

You may want to just do an adjustable FPR to bump up your fuel pressure:
