Hi, i have got a V4 sti which im replacing the engne due to previous one burning on me! i've had some help from someone experienced with the imprezas and he has told me i have the wrong turbo fitted, its a td04 from a uk spec car i've been told. What is the correct turbo for my car? Do i just modify parts of my existing unit or replace it, or even what would be the quickest spooling unit while maintaning a 300 - 330 bhp boost? any help would be greatly appriciated, thanks. J
P.S. The original unit would be my prefered option as im notin a possition to upgrade my ecu, but light mapping is an option. thanks again. J

VF24 is the standard turbo

The TD04 will typically do 280 bhp and the VF24 is probably good for 330 bhp plus.
The turbo is stamped on the front compressor cover VF 24 or TD##04## so there will be no question as to what turbo it is.
If you have an STi 4 then the ECU is mapped to run a VF24, not something that will run 50 bhp less.
First check what turbo you have and if you do not have a VF 24 think about getting one in good condition. These typically sell for £200 or thereabouts.
