Doing head at PortFlow, Arp head studs, cosworth spring and retainers. Trying to get my hands on a used Rev3 and a milspec or works 65 tb. After those few things I will see what the stock injectors will make with some more boost on poo gas, hopefully 340-350, before I decide which fuel to dual map with. 85 or 101? Opinions. Then eventually a MAP 2.5 or 3 turbo.

 

Nice list of mods. No ex manifold? Some good gains to be had there

 

There will be next to no gains with another exhaust manifold

 

OOps. Fp cast race manifold. Stage 2 excedy. Stage 3 TRE trans. Wow! No gains from any exhaust manifold? So you are calling all the masters of our Evo universe liars?

 

With your mods there are minimal, and I mean minimal gains. I have an FP manifold with more mods than you and I had very minimal gains. So there is my experience with it.
