stock tb is 58mm i think. what other mods do you have? a skunk2 manifold will give you a few peak hp. not really worth it imo until you have other mods like cams.

 

i have a greddy header, jackson racing hi-flo cat, evo2 cat back, and a injen race division 1 piece cold air intake.

 

the stock manifold and tb arent major restrictions until you start moving a lot more air.

get some cams and a tune

 

i am actually going to get a walbro fuel pump and a hondata s200 with the manafold and tb. then when i get some skunk2 valve springs im going to do skunk2 pro series cams. maybe after that a port polish and weight reduction.

 

do the cams, valvetrain and hondata first. you dont need a fuel pump. the pro series may be a little too big for the engine.
