Im wondering how much far people has pushed the stock manifold? Mr turbo has a good hi flow set up using the stock exhaust housing and bigger comp wheel with .7 cover for 1300. While my engine is getting built is it worth porting the manifold? I'm aiming for 500rwkw on e85

Or t04z on a hi mount :-p

I'm running the GTX3582r on stock manifold for 504rwkw on e85. It's the stock intake manifold that is restricting me now.

Has anyone got any pics of the stock exh. manifold "hi-flowed" using a die grinder or something of the like?

that's good power for a stock intake- is it an fg intake?

I'm still running the stock intake too just with a process west throttle body relocation

Had a look at mine, not worth doing. The design is what will restrict it

BF intake with pw throttle body relocation. Ported head and stage 4 cams help.

anyone bothered "port matching" the intake and exhaust gaskets.. im pretty sure they overlap a fair bit can anyone confirm?

where would I be able to buy a high mount manifold?
