03 JDM STi turbo onto a bugeye??
 
Will it fit? And what model is it? I know its a VF but not too sure of the numbers.

That would be a twin scroll turbo VF37 or VF36 if from a spec C, it wont fit without equal length manifolds and twin scroll downpipe. If you get STI headers you will also need the sump from a twin scroll car

VF30 is from the early JDM newage STI's MY01? It is not a twin scroll turbo.

MY03 JDM STi onwards will have a VF36 or 37 as i said above.

Saying that the VF30 / VF34 / VF35 / VF36 / VF37, they all use the same compressor housings. What sets them apart is either ball bearing internals and or different exhaust housings.

Get a pic of the turbo and compare to the pics below... Although its written on the compressor housing what model of turbo it is..Lol

Here is a pic of a twin scroll VF37 exhaust housing.

The twin scroll turbo wont fit onto a single scroll car without modifications, mainly half the engine! you need to go like for like or if your having the car remapped, a vf34 low friction ball bearing turbo or a sleeved bearing vf35 off a uk car :) (or another vf30 :))

I've bought the VF30.

What sort of power will I be looking at with;

H&S heatwrapped 3" to 2.5" downpipe
Full 2.5" decat
Decat uppipe
550's
Walbro
TSL filter
Samco y hose
Cold air feed

I'm hoping for around 330 with similar torque. I had a classic with 320/320 running a vf28 and loved every minute of driving it.

I think 330 is about right..:thumb:

AAAHHH!!!!!! The twin scroll is the same set up as my Evo 6 turbo. Therefore you can get screamer pipes for the twin scroll impreza turbos??
