I live in the ideal country to get it done as the cost of labour is very cheap and I know the guys to do it - unfortunately don't have an Alfa donor car.
The trouble I see with putting the Subaru lump in the 33 is that you'll eventually have to uprate everything anyway to cope with the power and I'm sure you are not going to stick with a lowly 218bhp for very long.
there is that side of it.
if i was to ramp the boost up to about 1bar and chip it and stick some nice exhaust (subaru one wont fit), induction kit and front mount cooler then i'm gonna be looking at around 280bhp.
the brakes on the 33 are rubbish for just 137bhp with another 140 on top of that it would never stop. the suspension wouldnt be up to it and the chassis is soft compared to modern 4wd turbo cars. or even other 4wd cars of the same age.. nissan pulsar, lancia delta.... my pulsar is the same age as my perm 4.
hmm, but if i just upgrade the flat 4 to take more power or stick a light presure turbo on it then i wont even make over 200bhp i dont think. fast for a 33 but slow in the real world.
also just by eye, looking at the alfa lump its quite a tight fit between the chassis rails. i dont think that the scumabru lump would be as narrow seeing as its 2.0L and the imprezza is a larger car.
would also need a custom prop shaft and proly custom front drive shafts too.
damn thats that idea out the window.
ok let me chuck some other ideas into the pan and see what ya all think.
1)turbo the stock lump and just put up with what ever power i get.
2)turbo it and take the gearbox off a 75 (or similar) to turn it into a rwd car
3)NA tune the car, throttle bodies, bigger bore, cams etc.
4) just leave it alone, its a classic and you'll ruin it if you mod it.
what do you lot think? if you had the budget or know how what would you do?
