Hi

I have a 2004 Impreza STI8 that has been running close to 400bhp with the following spec:

MD321H
Hybrid FMIC and induction kit
Samco turbo inlet pipe
Lateral GT spec headers and uppipe
Kakumei turbo back 3 inch exhaust
Lateral baffled sump
Lateral PR 650cc injectors (flow matched)
Walbro 255lph fuel pump
Simtek
Apexi AVCR

I want to fit a S206 turbo and aim for over 450-480bhp!

What power would the 650cc injectors top out at?

Is the Walbro 255lph fuel pump good for over 450bhp?

Is a uprated FPR a worthwile mod?

Thanks
Harry

Have seen 650cc injectors at stock pressure on Walboro pumps max at 440bhp.
You could fit a Bosch pump in tank and a pressure reg and this will see you there.
