Hi everyone.

I'm getting close to the point at which I am happy to fork out to get my 1998 Terzo mapped.

After lots of research, I am going to go down the ESL route (I think) and I am hoping to hit around the 350 mark.

My supporting mods are :

STI TMIC (with appropriate bonnet scoop & undertray)
Apexi Power Intake Induction Kit (with cold air intake from brake duct)
Walbro 255 fuel Pump
Yellow 440 Fuel Injectors
Reconditioned TD05 16g Turbo
Full SS Blitz Nur Spec R Turbo Back (heat wrapped)

My question is whether any of the mods listed will hamper the target of 350BHP?

I.e. Will I be better of with bigger injectors?
Or, will I need a decat up-pipe?

Thanks.

 

What clutch do you have? I had to have a pink box at 354 on my old classic. I also had the up-pipe and a fuel pressure regulator along with sc36 on top of your mods

 

I made 350bhp on my p1 impreza with hrc fuel pump, cobra sports cat, p1 stamped exhaust, and no other mods (Standard vf28 turbo). I did have the injectors cleaned and flow matched though. Cobra Cat only lasted 2 mot's before failing! Oh and shortly after mapping had to change to pink box exedy as well!
