The VF43 will fit fine. Are you sure they are pink injectors?

injectors will but it would need mapping to get it to run properly with them.

as for the turbo i think it is twin scroll as per previous post so would not be a direct fit.

It's not Twin Scroll, it's standard fitment on the USDM 2.5 STi.

Here's some info...

IHI VF43
(250-325whp, Bolt-On)
This is the standard equipment turbocharger used on the MY07 USDM Subaru Impreza WRX STI. It can be found on both base STI's and STI Limited's. The VF43 utilizes a thrust bearing design and the P18 exhaust housing. The difference between the VF43 and the VF39 used previously on STI's is the size of the wastegate. The VF43 has a larger wastegate designed to reduce boost creep issues.
Expect to achieve full boost with the proper mods and a quality tune between 3000-3500rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and proper engine management is highly recommended for all vehicles that utilize this turbo aftermarket.

Thanks for that silver scooby sport......! Looks like it will fit then. Where it says " owners will need fuel upgrades " i take it pink injectors and a uprated fuel pump will be ok?

I'm no expert but I would consider,

1. Uprated fuel pump
2. Uprated injectors
3. Re map for definate.

If your running a Wrx you may need to fit the Sti top mount but I would get some expert advise on this one, have you a mapper in mind they would be able to help you with what is needed.

Depending on what your paying there are some very good Hybrid turbo's on the market these days that will be worth taking a look at.

It's an interesting read and well worth doing your homework before this one, as they say do it once do it right

hi,

i fitted this turbo to my MY03wrx and is a nice turbo. a bit laggy but loved the kick it gave when came on boost which was around 3500, had webber fuel pump and that it and ran without any probs, got 306bhp on powerstation rollers and i think it was at 1 bar, so not much boost.

cool, looks like its the one...! cheers mate
