hey guys I'm new here to this forum.I bought a final edition Evo X about 3 months.the mods i already put in is:
ams front mount, upper and lower pipes
ams intake
ams downpipe
ams highflown cat
ams exhaust
1000 cc injectors
455 walboro fuel pump
cobb access port
i made 325/315 on 28 pounds of boost on a mustang dyno. My question is what can i do to get to 500hp.also what the best turbo can i use to get there?alot of people say fp black or gtx3576. so i was wondering if you guys can help me out on suggestions.also if some one has a link on info on e85 cause i would like to learn more about it..

 

Fp red will get you there so will fp black.
Some gsc cams
Gsc springs
And some head studs to keep the head in place.

And for e85 info go to Engine management Forum / Tuning/ E85 flex fuel and ecu flash section has alot of info.

 

could put a 35 on it and run lower boost

 

I have the same bolt ons as you, aside from the accessport, accompanied by a gtx 3576 and im sitting at 500 on e-75 (dynojet)
