as title say just want to hear your opinion about this daily drive setup for my brother 04 GTO :
1- LS6 243 cylinder heads
2- LS6 cam ( part# 12565308 )
3- 05 c6 90mm intake manifold ( part# 89017648 )
4- fast 92mm T.B
5- 1 3/4 kooks long tube headers ( with off road pipes )
6- K&N cold air intake

any one did the same ? , i'm wondering how the car will run with this setup
thanks

I think the car will run excellent, just like stock with a lot more power throughout.

I would get an LS6 intake instead of a LS2, it has a smaller opening, but it flows a lot better and you could reuse your stock TB. I would also check in with someone like Pat G for a custom cam, the LS6 cam isn't really worth the hassle of installing a cam for the actual performance gains
Just my $.02

Won't work with it. Send the factory throttle body to a sponsor to be ported. The GTO should already have an LS6 intake manifold. I would use the money saved from not buying an LS2 intake and put it towards an aftermarket cam, springs, and pushrods

If you're going to be going with a bigger cam, you'll want to go with bigger headers. 1 3/4" ain't going to flow near as much as a set of 1 7/8".
