How difficult is it to swap the impreza turbo 2000 engine and box to the STI setup? I want to forge an STI block and replace the existing unit.

Have a look at savage 's build thread he's done the conversion

Thanks. I'll see if I can find it.

Do you mean the newage sti 6 speed box ?

What version /year is your uk turbo ? As only certain year heads are compatible with certain inlet/fuel rail set ups .

I haven't bought my impreza yet but the plan is to buy a classic turbo and an sti engine and box so the closwd deck block can be forged before it goes in. As far as engine codes, which particular gearbox, what ancillaries to get, I haven't a clue. I'm an impreza newbie.

Closed deck blocks were only in the 93/94 imprezas from the factory so you'll probably have to source the "cdb" separately.

What sort of budget and power figures are you aiming for fella ?

Initially around 10000 including buying a classic scoob with a good body.

Will you be doing all the work yourself ?

Mine sets me back about 7k so far but I'd say I need about another 3k to tidy the paintwork and buy/map in a bigger turbo .

Which would make it mint with 400+hp

I'd try to find a jdm classic with a knocking engine and use it's shell as a base car .

they do tend to be much cleaner than the salty underbelly of our uk's especially if recently imported (in the last 5yrs)

Good call. Thanks.

Are the impreza engines generally reliable?

And i think I'll get scoobyclinic clinic to do the oily stuff for piece of mind.
