Ok, having searched a'plenty, has anyone else went down a similar path.
UK Bugeye WRX with full 3" cobra system inc belmouth downpipe, perrin intake pipe, green cotton panel filter. I plan to add a classic non catted uppipe and VF24 Turbo (both sat here waiting to go).
Basically, I know I should be replacing the fuel pump also to something along the lines of a 255 lp/h too. My main aim is to get over 300 horsies (and similar torque) but not push reliability to the limit as I am not looking max figures for pub talk. What can I expect from that kind of setup mapped and would I need to change injectors to keep away from hitting 100% duty on full throttle?

 

This kind of set when mapped should produce 320 + bhp when properly mapped,and no need to change the injectors as the std ones will bve fine with that sort of power.Enginewise, some people have hit 400 bhp on std internals ,but this is extreme.For the power your looking at your wrx should cope easily if it has been abused.
It might be worth also considering buying a 3 port boost solenoid imho to get the best out of the remap,can be bought for £30 - £50

 

standard bugeye wrx injectors will need changing if you plan on going over 300bhp, mine ran 286bhp and were at 96% duty. It is always best to have some headroom in there.

 

Hmm interesting, anyone else want to add before I get any more confused?

 

I took expert advice when I went for a similar setup to yourself, and opted for STI pinks. (Look at Level 2 / 2A)

Hi matey have look at this http://www.scoobypedia.co.uk/index.p...rFromInjectors

 

Cheers guys, might have to factor a set of pinks in then to be on the cautious side. Gearbox etc is fine at the moment but really don't want to be getting hit with many high cost repairs.
