ATP Turbo?

ok so I have been considering this turbo from ATP. It is a GT3071R, stock location. I haven't heard a lot about this company and am trying to get some info on them. If anyone is running there turbo or has heard anything please chime in. I was considering the Blouch Dom 3, But have heard they have problems holding peak boost. Here is the link below.

that's a lot of turbo for your little 2.0L... hope you don't mind lag.

Thanks for the replys guys. PPG's will be going in this spring, before the turbo, so i'm not worried about the trans. I can deal with the lag untill next summer when a 2.5 shortblock, forged pistons, p&p heads, and cams will be going in. But then again like shoaf tells us "power is just a down shift away".

shoaf certainly has more tolerance for lag than I do... I can barely drive the stock EJ20 anymore without getting frustrated

I know what you mean mosc. Do you think this setup with all supporting mods could get me into the low 11's in the 1/4 mile, maybe HIGH 10's with race gas and a good tune?

that's total speculation that's pretty hard, especially because I don't know your drag racing experience.

Cars with 2.5L and GT30Rs though are generally around 11s though, give or take a ton

you can use a site like this:
Estimate ET for Quarter Mile using Horsepower

but they're not set up for AWD so you have to knock some of your HP off. Maybe like 10% off of flywheel would get you in the ballpark (we have about 10% more losses in the drivetrain than a RWD car does). More if you're inexperienced. Figure something like 450 flywheel HP? put in 400 & 3400lbs and it spits out 11.9
That's about as good as anybody's going to give you
