Hi wondering if i could get some advice. I got my classic import wagon wrx sti rolling roaded a couple of months ago it made 273bhp since then i had a custom straght through exhaust made and fitted but i was wondering what else i can do to get it to 350 ish. Thanks for any help sugestions you can give also engine wise i think its pretty standered pretty new to scoobs so dont know to much about them.

 

A vf35 turbo, 550 injectors, newage sti topmount or a front mount and remap.


good for around 330-340 mark.

 

what year car

 

1997 mate

 

What's the boost set at mate

 

What's the boost set @

 

0.7

 

What is the oe turbo?

 

Boost seems a little low.

As above though, to reach 350 you will need different turbo, injectors, Remap and possibly better cooler.

What's the clutch and box like ???
How many miles has the car done ???
Is it on standard engine ???
What's the service history like ???

All things you need to consider when pushing an old car above 300bhp. Don't blow all you money on 350bhp if you can't afford to fix it if it all goes wrong.

 

clutch and box seem fine. the car has done 49000 mile but most of that is km. ye still standered engine. dno much about the service history as i never got much with it belts were done at 23k but im going to get the belts redone and a 50k service from subaru before i make a start to upping the power. at the rolling road the boy said that i was needing a bigger fuel pump.

 

Yep uprated fuel pump should deffinately be done. Something like a walbro or the like.
