upgrading intake and exhaust!

[dcrusupra]

How much money do you have to work with? You need to find someone to do the front facing intake. You won't find any performance shops that carry them.

And do what j3pz said.

A 4" exhaust is a little overkill. The biggest I'd go is maybe 3. If you get a dual ball bearing turbo, you'll need to reduce the oil feed line and increase the oil return line on the turbo. Too much oil will kill that kind of turbo. Just look into an upgraded CT26 for right now. Maybe a 57 trim. There's no need to upgrade the exhaust manifold unless it's cracked or something. They can hold quite a bit of power.
