i've been working my *** off last few months and using the p1 as daily driver so lost a bit of the 'feel' of driving her, but recently got another car for our daily stuff and took part in a drag race which gave me a bit of a kick back in the mood. the car was pretty well tuned when i got it but now i just want MORE POWER!! heres a wee spec list;

Model: Subaru Impreza P1

Drivetrain:
Powerstation strengthened gearbox
Exedy Racing Origanic clutch
Ligthen OE flywheel

rolling road'd at 364bhp

its only mapped at 1.25 bar boost so theres a bit more give there but since i live on a sh1tty wee island off the north of scotland a remap is quite a few quids worth away. i got hold of a gizzmo ibc boost controller off ebay but i'm a bit reluctant to fit it without a bit more experise.

so what now?? where do i go from here and should i fit this boost controller or not?

 

md321 turbo and remap, simtek ecu an hope u get to 400 bhp

 

with boost at 1.25 bar i'm thinking increasing it is the best way forward, but how much is safe??

 

Making some good power their mate, as above bigger turbo, md321h would be my choice

 

interested in the PowerStation strengthened gear box...how does that work than?

 

i got a vf23 on mine an mapped at 1.4 bar. id think these being later developed they shud handle that sought of boost but somebody else would know but the vf maxes around 350 to 370 i think so id think a new bigger turbo will get u up the power range quicker
