I got a question on this bad boy... I'm in the processing of saving up money to finish my turbo kit that I have under my bad. Now for the question... On the hahn racecraft website it says recommended for applications of 15psi or higher, I was wondering is that also a minimum or can I run oh say 10 or 11psi boost?

The turbo I have is an EVO III 16g turbo, if yall needed to know what kind of turbo it is... any other questions feel free to ask:cssNET:

because you dont seeing much of a gain till you hit the 300+hp mark. You can put it on and it would help just not nearly as much as it would if you were 300+hp.

I'm pretty sure you'll need the mitsu flange for that turbo. Most are t3/t4

You will see gains with the Hahn IM. But if you are only going to push that low of a PSI you should consider saving some cash and buy a SC delete kit.

I'm going to be running 0 psi on mine. I'm getting the manifold before the turbo, so I'll be N/A with that manifold. Hahn said I was fine to run it N/A. So if I'm good to run 0 boost, I think you'll be fine with 12 psi.

sounds good, maybe I'll do the same:guns: are you getting yours with the port fueler? and how does that work?

The port fueler is an extra set of holes for more injectors, so you can run a set of stock injectors in conjunction with a set of 60's. I'm not getting it, I'm just running one set of either 79 lbs/hr injectors, or 83 lbs/hr injectors on mine.

I want one so bad. I wish it wasn't like $800 though. I guess that's what you pay for a quality piece though.

I need to sell my 2.4 and go ahead and get this one and run it Na until I get boosted.

i have a friend running one on his n/a built ecotec cavy. when he put it on he found it moved the powerband way up.

you can run 10psi on a stock plastic manifold so you dont need to buy the hahn intake. a friend of mine (i built the car pretty much) has a turbo ecotec pushing 12 psi on stock manifold with no issues

I "blew" a hole in my plastic intake manifold on my Ecotec Cavalier running 12 PSI. This is a must upgrade for most all turbocharged applications!

Im still running my composite intake manifold at 11+ psi for a while now with no issues.

guess I'll just do the audio first then... don't wanna pay for tuning twice if I'm just gonna turbo the car sometime around income tax season.
