04 STI planning mods before ecutek remap
Hi,
I have recently bought an 04 2.0 STI TYPE UK Impreza with PPP. I am looking to modify the car to run circa. 390 BHP.
I am hoping to get some advice from somebody that has managed to get this sort of power from a similar car.
What mods do you recommend?
Will i have to change the injectors/fuel pump considering the car has the PPP fitted?
Is the standard top intercooler up to the job or will i see better results with a front mount?
I want a turbo that pulls hard towards the top end of the rev range (ex Honda Type R/ S2k owner
), any recommendations?
I will most probably running a Blitz Nur spec exhaust with 3" decatted down pipe.
Any other advice on recommended modifications would be greatly appreciated.
Thanks
Harry

392bhp/361lb torque myself.
What mods do you recommend? TD05/18g + Booster/Meth, or TD05/20g, or MD321H Turbo. 3" exhaust, colder plugs, CAIK, 3 port boost solenoid.
Will i have to change the injectors/fuel pump considering the car has the PPP fitted?
For 390 you wont need to change injectors, but they'll be about 90%+ duty cycle, over 400 and it's best to.
You'll have the uprated pump as part of the PPP. If not, the walbro 255 £80.
Is the standard top intercooler up to the job or will i see better results with a front mount?
Top mount is proven to be efficient well in excess of 450bhp. If you're tracking your car, then a FMIC would be advisable, otherwise, not.
I want a turbo that pulls hard towards the top end of the rev range (ex Honda Type R/ S2k owner), any recommendations?
All the above turbos will do that. More so for the latter, but you'll lose early spool. 18g is a good compromise. Again, depends on what you want.
I will most probably running a Blitz Nur spec exhaust with 3" decatted down pipe.
Noisey!
