hi all, this question has probably already been asked,
I have a 2002 wrx bugeye with de resonated middle section and back box, in wing air filter, which i am loosing the love for, so i figure an upgrade is needed,

My question to you guys is:
What power are your wrx's running and with what mods? and have you had any issues?

i am looking into sti top mount, decat up pipe, sports cat downpipe, 550 injectors, walbro fuel pump, vf35 turbo and 7 plugs.... and remap

any information will be appreciated as i dont want to throw the money at it and be let down by reliability or change of performance. Would hope to get 300-350 bhp
Thanks

 

This would be the same spec as my wrx was but have since upgraded to avcs too, But was producing 332bhp with 329Lbft on the wrx heads and block with the above.

 

did you have any trouble/ problems at all? and how long was it running that power?

 

Mines running 278bhp

Standard turbo,
standard intercooler,
standard injectors,
prodrive Y pipe,
de-cat up pipe,
de-cat downpipe.

Recently purchased

TD05 16G,
STI top mount.

To come

STI pinks,
3 port boost solenoid.

I'm hoping with this i can get to Around 330bhp

 

on my import classic ive got 307.4 bhp with a td05 turbo,autobahn fmic, turbo back exhust no cat and hks superdragger backbox and a chipped ecu that no ones ever heard of but power was good and strong till head gaskets went

 

My hawkeye has got a milltek 3" turboback with sports cat; harvey ported/wrapped headers and uppipe; harvey ported VF35; process west TMIC and shroud; colder plugs; walbro pump. The hawkeye already has the 550cc injectors and the AVCS heads. I'm getting 327bhp/338 ftlb on Powerstation's dyno. Compared to the 2.0, the 2.5 gives more torque, but the chocolate engine limits boost to about 1.25. The 2.0 is more robust so can take more boost, so somewhere in the region of 330/330, as Gaz says, sounds about right. Exact figures will depend on the map and how the dyno is set up. You shouldn't have any problems at that level, not too much for the clutch and box. The VF35 gives a nice quick spool up, particularly with harvey's pipework, but it's worth getting the wastegate ported to avoid boost creep. The VF34 will give a little more, closer to 340

 

my hawkeye wrx is running 355bhp, with vf43 turbo andother supporting mods

 

my hawkeye wrx is running 340/400 vf34 remap

 

All sounds good but put some money away each month for a gearbox as it WILL break. Friend of mine same mods VF28, is just killing his second box on these mods.

 

I would have to agree with the above , because with extra power comes extra torque and that can kill std gearboxes with big power going through them . My uk turbo with a vf28 is pushing out 330 bhp /325 lb/ft torque , and although i have been told the std box is good for 350 bhp ,it still does not hide the fact that when subaru fitted it in my car ,it was fitted to be able to cope with 215 bhp & 211 lb/ft,so a 50% increase in power/torque is going to stretch the box imho. For a uk car I think i am at the maximum bhp for the turbo and i have a spare clutch & box should the current one decide to let go.

 

my blobeye is running 353bhp 351ft/lb torque with no problems spec is
vf30 turbo
sti topmount
sti pink injectors
walbro fuel pump
fully decatted
harveys ported headers and uppipe
green panel filter
3 port

 

Td04 h, STi 8 intercooler, fpr, porter headers, 3 inch turbo back.
On a MY00 classic. Running 300.1 bhp with similar torque.

Standard clutch went so had Exedy organic in (+50%) but then 12 months later gearbox went bang.
Just in the process of having 6 speed and drive train upgraded (diffs, hubs, shafts). Do be prepared to shell out. Would have been cheaper for me to go STI in the first place, but I am where I am ... and I love it
