Engineermike is at 700rwhp with his log manifold setup and a T76GTS (the best T4 T76 out there)... so he is at the upper limit. I'd say realistically... 600-625rwhp is a good number to shoot for if you have a good set of ported heads and a decent cam.

alright, do u think LE3s would be fine, or ported trickflows, or maybe pick up some of the new brodix heads, or what?

 

In order to lower the compression, pick up some deck height and get the most flow... the LE ported TFS heads would be great. LE3 heads are great too... but the have the small combustion chambers.

 

Thanks for the prop's, guys.

The T76GTS is a good choice, but there are some alternatives out there now.

If you want to spend a little more money and have a little more room, the new ST series turbo's are awesome. Smaller than the S400, but will support up to 1300 hp. They're a little more pricey, though.

If you want cheaper, the Turbonetics TC76MPS will support 1000 hp and only cost around $1100.

Those Borg Warner ST's are comparable to the T4 GT42's... still freakin huge turbos.
