sorry but this has probably been asked a million times before. i have a blob sti type uk running 332bhp
spec is

full 3" de-cat turbo back
walbro 255lph fuel pump
cold air feed
remap all done by scooby clinic before i bought the car.

my question is would a vf48 and some blue injectors from the hawk WRX be a good route to go down for value for money bhp wise as i am in the process of buying a house having loads of money to throw at the car isnt an option or i would have bought a sc46 turbo or something like that. could somebody give me an idea of what power figures i could expect from that turbo fitted to my car. any advice would be appreciated thanks

Hi mate I've got a sc46 on my blob Sti
Amazing but it ain't cheap
If your after vfm stick under 400 hp as to get to 460 is thousands
If you can get a sc36 38 second hand and see 360/380 hp and ballistic spool
Up to you budd

 

Speak to kev about the next stage.as mick said after 400 bhp it starts to get expensive

 

Ad be over the moon with 400bhp. Tbh if I coul get it upto 370-380 ad be more than happy. Al look into prices on second hand sc38's thanks for the advice.

 

which turbo have you got at the moment?

 

It's the standard VF35 mate. Trying to way up money to bhp ratio ha c if it's actually worth doing I.e noticeable difference for my budget.

 

Your car, mods, turbo are same as mines, dyn'd at 320 but i too am looking at a sc36, vf34 possibly or harveys td05-18g. want to keep existing modsstay well below 400 around 350 with good spool important. the vf35 lacks as does at top end power. going to go with harvey up-pipe with new turbo if i do.

 

It's a mind field of different views and opinions. I just want 400bhp haha

 

I got 395hp out of an SC38 with 555 injectors and a Hybrid GT2 FMIC on my STI RA. I'd try one of them if you are needing near 400.

 

Good result. Am hoping to keep my top mount. What brand of injectors u use? Lot people think the STI pinks r 550cc that there only just over 500. That's what was thinking the blues out the hawk WRX as there 565cc or there abouts
