Headers for turbo?
#11
I looked into CG fabrication...they make a great hotside for our cars...but you have to delete the A/C...so thats a no go.
Im gonna trade soldier for his shorties...so i think im set. If they don't work ill buy something but imma try the free thing first

Hey guys. I know I haven't posted in a while but whats up. Your stock manifolds are not a restriction under 1000 RWHP. Seriously. They are that good. There is no reason for replacement. I never have liked ON3. Just me.

Well how would you know that unless you've done it yourself? If we're using researched knowledge, than I can input some info here.
From talking to the shop I was dead set at having build my turbo kit, I know that the stock manifolds arent that restrictive. But the fact that they face backwards and you have to route tubing from around the rear of the engine and up to the front where the turbo resides is what makes the stock manifolds less than ideal. A forward facing designed header, or at least one that drops the exhaust right from the manifold that it doesnt have to take a 180* turn to go forwards.
Added tubing plus all the bends make the setup less efficient, its not necessarily the exhaust manifold/header itself. The ideal placement for the turbo is around 14" away from where the exhaust gases from each of the cylinders in each bank meet. This is what the shop told me when they were schooling me on what they would do for my setup. I was essentially getting a similar setup to an 03 Cobra that was in their shop, and that setup with 16psi on a stock 03 Cobra motor with the 99/01 manifold yielded 747rwhp and 784rwtq on pump with a precision billet ball bearing 76mm. I would have been going with a much smaller turbo, like a 62mm or a 67mm, but the setup would be the same. That setup is crazy, and its efficient because it routes the exhaust gases forward instead of rear facing. Just saying.

No I don't think On3 just sells the FF headers separately. I know they will be selling an upgrade kit to members that already have the regular kit but thats it...ill email them and ask them though just to make sure.
