I only have a 2.5 inch exhaust exiting to a y pipe, I think that will be my biggest bottle neck. I also have cats for emissions and that egg smell! What amount of boost do you guys think it will take to hit 600? I will have a bid or two and a dyno sheet in a few days!

Exhausts size won't be an issue at all. If you have emissions that will be a bit restrictive. To get to 600whp on pump, 17psi should do the trick. Ideally, the 1.32 a/r housing is key, and I don't remember what you had ordered.

So you think the cats are the worse of the two? hum... i have to pass emissions so they kinda have to stay. um the box says i have 6266 sp cea-1-bb1 w/th15D-66. I'm not sure what that means, maybe that can help?

Just have to pass the sniff test? Get some higher flowing cats.....

What's the A/R reading on the side of the compressor housing?

You might have to consider replacing the compressor cover if you don't make the numbers you are looking for.

I definitely will, i should be close with this turbo. Does anyone know what this turbo will make for psi?

The turbo is good for 30psi...but remember, pressure is resistance to flow. So if the turbine is too small, the pressure will go up, but power won't.

The telling sign that you have reached turbine flow limits is the torque numbers approaching horsepower numbers.

You will know a lot more after the dyno.

Ideally, for built engines, you want the 1.32 a/r turbine.
