WRX engine BHP
I think this might open a big can of worms here but i was wondering if anyone knew what is a safe limit of bhp & torque for a new age wrx engine is (not STi) with standard internals, i know this is a very vague question but hope some of you lot can help.

Granby,
I am running 368bhp with 331ft/lb torque. Been over 350bhp for over 20k miles.
So far, so good (frantically looking for some wood to touch)
Car is a MY01 WRX
Cheers

RB5Scott was running a little over 380bhp on his UK300 (on two separate rolling roads). He then changed the headers to get more still, and had another re-map, which he thinks could have taken it past 400bhp, but IIRC it knackered a piston on the way to Power Engineering to prove it. (Still made 340 odd even with a hole in the piston).
I'll leave him to comment on how many other bits he's broken since

There are a number of classic WRX's/UK's that have made over 400 bhp on std internals and are still running strong, the 01 onwards should be no different, if anything they have a better base engine to start from than the early cars.

My way to 400 on a Sti 01 onwards would be Tubular headers. £400
Heat wrap headers. £100
Cold air intake. £200
Silicone intake pipe. £200
Pump and adj reg. £200
TD05/06-20G. £900
3" decat system. £400
EcuTek custom map. £600
Prices are approx, you will find the parts dearer/cheaper depending where you shop
