Power upgrade for 2003 wrx sti???
 

Hi guys just purchased a 2003 wrx sti type uk, just wondering what is recommended to get a power gain to circa 300-330 bhp?

It is a standard sti so no pro drive pack.

It currently has a scoobyclinic back box and standard the rest.

Cheers

Walbro fuel pump, uprated panel air filter and remap. That should do it. :thumb:

Thanks mate, would it be ok with a pro drive back box as the one it has now. Is a bit big for my liking?

Cheers

Full decat prodrive system has a luvvly sound and doesn't give alot of cabin noise thats what im running as said above fuel pump, panel filter remap, 500-600 quid all in and youll be good for about 330

I've got a sports car downpipe and mid pipe as well as rear box on mine. Nice and quiet round town and nice and loud on the loud pedal when required!

You may need to look at the cats to get the best out of your standard engine setup, but equally we have seen good results from relatively standard STIs.

exactly what he said.

+1.for starters;).SJ.

Spark Plugs too forgot about them

Cheers all, any good/bad experience from any mappers ? Best worst etc.....

Racedynamix and Jolly green monster do mapping sessions up and down engerlandshire and will probably be mapping somewhere near you at some point
