st185 power options

hello

below is the current spec of my st185 jap import, i am looking for abit more power before i think of going down the forged route.

fmic with 2 1/2 inch pipe work
custom breather set up
apexi induction kit - afm removed
ct20b turbo
3'' turbo back exhaust with no silencers
mishimoto radiator
elctronic boost controller
link g4 managment
fensport air con removal kit
fensport light weight alternator pulley
dynod @ 254bhp at the wheels using 8-9 psi, fuel pump got lazy @ 10 psi
oviously next is to upgrage the fuel pump and do another map session. just seeing if their is anything else i could do for a little more power.

cheers

I'd say fuel pump and bump the boost up to the 15-17 range.

Also fit the 205's injectors.

Supra TT fuel pump.
540 Gen3 or 550 supra injectors or some Sard 63561 650cc injectors like I have.
Dual feed rail or aftermarket fuel rail and lines and convert to e-85.
Not sure exactly how the Link4 works but maybe you could have 2 different maps one for regular and one for e-85 so you could switch if you want to for economy?

Did you have the Link G4 fitted ? Did it make a huge difference ?
