boost??

[srswap20det]

hey i was just wondering what everyone is running for boost and what you use for fuel management because i herd chiped ecu's aren't that good??? and also what turbo's?? im looking to upgrade and i just wanted some input so any help i could get is good thanx

it all depends on what you are trying to achieve. A normal setup is s15 t28, 550 injectors, z32 maf, fpr, and safc. You should be safe around 15psi, but all cars are different so you should tune it with afr

who told you that chipped ecus arent good???

i have a t25 with upgraded internals, they call it The Forced Performance Big T28. anyways i have an apexi HG and 3" exhauts, i dont have a safc but i am runing rich regardless. i have ran it at 21 psi and it was good and f-ing fast. but i daily drive it at 12psi with of course no probs. maybe that helped. i have no ecu upgrade or injectors just a front mount, hg, and fp.

i run 10psi daily on stock ecu..... theres nothing wrong with tuned ecu they just tend to program it kinda rich so you dont blow your ****. search next time. lots of your answers could be found there instead of posting and waiting for people to respond

yeah i think im gonna run stock turbo for now with big injectors and a D-jetro Power FC at 20lbs until i can get the money up for a turbo unless i can find a good turbo for a good price

running an enthalpy tune for 555cc deatschwerks, z32 maf, walboro pump, pushing 18lbs on a engine with a cometic hg w/ arp studs. pretty good set up for daily driving

Under 350 WHP a chipped ECU will do fine. I am at 7 PSI with stock injectors but I have a JDM SR ECU that's been rechipped with a Mine's Engine Management program. The only thing most boosted 240's will need is an upgrade MAF (Z32), high volume fuel pump, injectors and an ECU reflash. Although making any sound advice on this issue would require knowing what car you have and what engine it is . If its an SR20 all you need for 350 WHP is the .86 A/R GT2871R turbo, 740cc's (overkill maybe but it you ever decide to up the boost later on down the line you'll be happy plus you'll have a good safety zone and won't max out the injectors) MAF and FMIC. Nothing else is really necessary.
