Default Engine differences between an impreza and forester

Hi guys, my 98 UK turbo motor in my beach buggy is shot and I've been looking at a cheap forester as a donor vehicle. But looking at the power figures the forester is well down on the impreza engine I was running.

Can anyone tell me what makes the impreza so much more powerful? Is it turbo? Injectors? ECU? Or a combination of all the above?

Next if it is just the bolt on bits that make it different could I use the bare engine with heads and bolt my inlet manifold onto it. The forester is a v reg by the way.

Thanks in advance, Ian.

Very basically the UK 2.0L Forester runs softer cams and a smaller tubo as standard. A JDM Forester has basically the same engine/tubo as a WRX.

Fitting a TD04 to a UK 2.0L Forester + remap can get it up to about 260BHP

As a long block replacement using rest your parts like turbo etc will be perfect.

P.S does anyone know if my 98 inlet manifold with the coil pack in the middle will fit onto the forester block?
Failing that will there be much to altering the wiring I have together it to run?

Thanks Ian.

Have a look at http://www.subaruforester.org/vbulle...-2-0-xt-24249/

The 2.0 XT has roughly the same engine as the Turbo S
