Hi guys what kind of power should you achieve with theses mods.
It's a blobeye 2004 sti type uk with 28k on clock from new

Aps sr 40 turbo,aps 725 front mount intercooler,aps hard pipe kik,aps 65 mm inner wing,aps bov valve,aps fuelling system, breather kit,800 cc injectors, koyo fast rad, greedy oil cooler,Walbro 255 fp,full 3" Haywood Scott exhaust no cats,RCM headers,RCM up pipe,iridium plugs.

There's probably a lot more I have missed off.
All thoughts would be appreciated.:

 

Around the 400 mark d guess at if its a 400 brake turbo?

 

around 380bhp, the APS turbo is an old unit now and pretty laggy, i had one on my old car and it made around 370bhp with supporting mods, best thin i ever did was get rid of it for a better turbo

 

Thanks guys for the comments. The turbo is capable of making 440bhp.

These bits have been on the car for 6 years now and still like brand new and the car hasn't missed a beat, when mapped it achieve 426 bhp, but now running at 413bhp & 400 flb.

 

I had one in a classic it made 390bhp. But was laggy as hell

 

Why ask a question if you ready know the answer?

 

its claimed to be a 440bhp turbo but dont expect to see them go over 400
