wrx hatch not much power
Hi i bought myself my first ever scooby last janurary and love it but was a little disapointed with its 227 power output , its a stock 2008 wrx hatchback i dont have loads of money to throw at it mainly cos it is not my only car and i did pay 12 k for it . Has any one got any suggestions as what i can do to increase it without breaking the bank . I was toying with the idea of putting a adjustable turbo pressure valve/bleed valve on it but i have heard mixed views on this .opinions please !

A remap for £500 should see you at 260bhp ish
With a few other simple mods you might see 280bhp

The WRX is a real puller when mapped. The turbos aren't as efficient as the older TD04s but with a decent cat back exhaust, filter and a map you can see 360lb/ft of torque at 3000rpm and a peak of around 250-260bhp at 5800rpm.
What you must be aware of is the pistons are prone to cracking on the ring lands with a lot of boost. It's hit and miss, but the suggestion would be to replace the pistons with forged items to be able to really push the engine hard.
