MY05 Sti 400bhp+ fuel pressure regulator and pump type
Currently running a MY05 STI 2,0 EURO (sorry bad language, from abroad)
- stronger bottom end/ studs/gaskets etc to
- GT30R hybrid
- Jun cams
- walboro 255lph
- Motec M800 ecu
- close ratio Spec C gearbox
- uprated radiator, APS FMIC
- list too long etc
Dynoed at 411bhp/511Nm on 99octane pump fuel on monday on a very conservative dyno. but now with redused exhaused housing for improved spoolup, and everything is super now)
Currently no problems. Rough idling when cold, when warm a bit too low idle.
But i have concens about fuelling:
- should i fit a uprated fuel pressure regulator?
- tex RCM sell different type of pumps, is walboro wich im currently running 255lph ok?
any piont of views of these matters?

Its a rotated GT30. STI Inlet manifold is also reversed , and power enterprise 800cc injectors, and APS DR650 FMIC.
Not running lean and the motec is professionaly mapped.
My concerns is that I see that Scoobyclinic, Powerstation etc all list FPR in their 400+ setups. Thats concern me.

99% of all aftermarket ecu are very sensitive to atmospheric conditions, and hence tend to be a bit cranky on cold start, make sure you prime the fuel rails (turn ignition to point just before starter motor kicks in and hold while you can hear a buzzing from the pump).
the idle may just need slightly increasing in the map
