How much could i boost?

[bp2ooo]

I have a general idea, but would like to get a more for sure answer. MY setup will be a s13 redtop. With intake, and downpipe from afterdark. I will get the greddy vspl front mount, and greddy profec b to control the boost. I dont think i will be able to get new injectors right away, but would like to in the future. So for the time being i was leaning towards the hks fuel pressure regulator. It says you can raise fuel pressure about 5 psi, and i will have an walbro 255 in the tank. Other mods that i am doing is a hks ss bov, and a act street strip clutch. I am thinking i will probably be able to boost about 16 psi? pretty safely i hope? that would have the stock t25, and stock injectors pretty much maxed out. Do you think this sounds about right? what kind of boost are you running bud with your swap, since you have the same front mount. Thanks guys, Chris.

u can run 16psi without harming the engine, but you will be harming the turbo...anything after 14psi will start to shorten the life of the turbo.....but your setup can support more, just not the turbo.

and s15 ball bearing t28 would be my cheapest upgrade right? Hmm, i think i am gonna need to start saving up for a new turbo, and injectors.Thank you very much for the helpful answer by the way.

the T28 is hardly the cheapest upgrade, but it is a reasonable upgrade. If you're using a stock ECU, you're probably better off with what you have got. The stock ECU doesn't map past 1 bar, so after that it just kinda does whatever, so it's hardly efficient. Just keep the T25 until you can afford some sort of ECU upgrade, even if it is just a piggyback.

i wouldn't run over 14 psi even with some fuel upgrades, because you would shorten th elife of your turbo. i say stick with what ya got now then save up for an ECU upgrade

well this is just the start, and all i can afford for now. I had to buy a winter beater because my ka died. So now im just waiting for motor. Hopefully within a year i will be able to get a turbo, injectos and ecu. What other options do i have for turbo for around or under a grand. Can you have a turbo rebuilt in stock houseing that would support more boost?
