hi there,

i have a 1993 wrx with walbro fuel pump, remapped, hks filter, hks full system exhaust, apexi boost controllerand uprated clutch.

where do i go from here to get more power?

would be happy with 320bhp

cheers

andy

 

I guess the exhaust system is a decat?

Better brakes (unless already done)

Bigger injectors + FMIC/Better TMIC(another remap)

 

As its a 93, a bigger TMIC would be a bitch to fit. Probably cheaper and easier to fit a front mount, though you will still need to do some slight mods to make one fit ( nothing too difficult though ).
After that you could fit some ported headers and uppipe.
What Ecu are you running on?
