Hi

I currently run a MY93 WRX with full decat and a 57i kit, standard internals. I'm now thinking that having owned it for 18 months i want a little more power.
Any suggestions on upgrades without putting the engine under serious stress and what i'd likely to get from them.

Thanks

 

bigger turbo and injectors and a power FC ecu id guess....

 

Walbro pump , fuel reg,+ remap on top of your free flow intake/ and out, exhaust!, Pavlo will do a good job!!! Cheers Pete

 

On top of what Pete said i'd go for some 440 injectors for the remap & you'll also need to change either the MAP sensor or get an electronic boost controller to bypass the fuel cut if you're increasing boost to over 1.2bar. Your K&N should be fine & I guess it's running a TD05 turbo which to avoid unecessary expense replacing should be good for 350BHP anyway
