Upgrade question

[4g63dsm]

I have an Intake and Cat-back exhaust if I get a greddy bov and upper IC pipe will I need any fuel upgrade like pump and or management. How much boost would I be getting if I did that? Thanks

You will be ok without the fuel pump etc until you start raising the boost levels. The mods you have plus the IC pipe will just enable the engine to run as it should, you boost will remain pretty much the same until you increase it with a boost controller.

Back with the T25, when I put on the UIP/BOV and a cat-back, I was seeing 17psi constanly w/o a boost controller.


I would suggest at the very least, doing the fuel pump re-wire mod

Like Rob said, you are good with just a re-wire until you hit 12's. After that throw in a bigger denso (my favorite) or a walbro.

Umm... I don't know about "doing fine" till 12's with just a fuel pump re-wire.... I'd suggset a new fuel pump if you put any kind of an upgraded turbo on, or if you want to run more then 17psi on a T25 (which is pointless, but you get what I'm saying)

Thanks for the help guy's. One more quesion if i get a new pump on the stock turbo will i have to get a SaAFC or something like that to controll the extra fuel that its pumping

You aren't pumping any extra fuel to the engine, you are just making sure the engine isn't getting starved at higher rev's. I know a girl who ran a 12.2 on a rewired pump and stock SMIC. It was fully logged and she is not low on fuel. A stock pump flows 40% more at 14v (140 lph)than at 12v. 450's at max output take 108 lph. There will be some loss in the fuel line, but you will still be able to max out 450's without a problem.

No, you will not need an AFC till you get aftermarket injectors or a bigger turbo.
