Gab, I think we went over this a while back, you are fine....
I know all of that!
Question: If you swipe your finger on the inside of your exhaust, what happens? When I do this on mine, my finger gets covered in black and smells like gas. Is that normal, I don't think so!

If i were looking at the boost levels/HP numbers that you guys are, I would not be considering the 28RS... the GT30R is a slightly larger turbo + use external wastegate + less top-end dropoff. Slightly longer spool time but you should be able to get it to spool by 3600, 3700rpm with some breathing help... one of those nice Edelbrock IMs, bigger TB, and GSR cams should do the trick.

I dont understand what your saying. YOur hating on the gt28rs but you skip the gt2871r and go straing to a turbo that doesn't make boost till 5500 rpm and then tell us it spools at 3600? Posotive manifold pressure is what your talking about? The gt28 anything will give you that shit at like 2krpm. 10lb before 4k every day.
And you really think / have seen a TB make a difference in turbo spool? I thought turbo spool was almost directly related to the velocity of the air as it passes over the turbine. I know there is a pressure change that causes the turbine to spin, on top of the mass of particles hitting the wheels.
GSR cams really wont make your turbo spool earlier.
The Edelbrock manifold has never really moved the power curve down on any before/after dyno's i've seen...

Haha, no. His sig says RIP 06/13/05 so I clicked 'show all user's posts' and looked for something on either 06/13/05 or 06/14/05 and voilą

Am I still thinking about B18C numbers here or am i just flat out wrong? The GT30R isn't that much bigger of a turbo, you could also just use it's compressor side on a GT28RS I guess, plus I have never heard of the GT2871....
I have been getting alot of stuff wronglately maybe my brain is rattled
