GT-GO

Im looking for some advice on a really nice front mount turbo combination setup for the track.
Ive picked up a really nice set of hot side pipes with a T4 flange so that is already sorted

The car is a GTO (heavy *** sucker) with only 30,000 miles on it, which so far has:
- stock LS1 (346ci, LS6 manifold, stock heads)
- 4L60E auto
- 3.07 diff gears
- 3" true duals
- stock suspension (Ive got revalved 90/10s and drag bags here though)

So I need to pick a T4 turbo, a good converter and a cam to all work as a package.

Planned mods are to keep stock cubes and run a set of forged pistons, better rods and rod bolts. I'll run an SD tune also. The only other thing limiting me is I want to keep the 4L60E or go to a new 4L65E when I have to.

I was heavily leaning toward an A2A intercooler but might consider a A2W now after reading that other thread.

Apart from that, my options are open. Id love to hit a high 9 eventually

Whats the best path from here?

get the turbo to make the hp you need to run your et goal. call Yank and talk to dave and get the right comverter. PM PatrickG and get him to spec you a cam

Give us a call, we can spec you the turbo for the setup. 9's are not a problem with the right unit.

So Im best off picking the turbo first, then get a converter made to suit, then getting a cam specced?

What size turbo could flow enough for my needs on a T4?

I was hoping someone had a combo that worked well that I could have a bit of a look at.

Ive been having a look at these 224/230 cams and also the SpeedInc 225/225 grinds.

TC78?
ST80?
S400-80 w/T4 flange?

Which of these would work more efficently?
What can I use to accomplish my goals?
