i know a guy named Brian in derby, place called POWERHOUSE, he has the old AE82 mk1 gt corolla hatchback,
with a turbo setup, and some how he managed to do a 4x4 conversion to it,
believe me this guyS Corolla has put impreza's to shame, il look up to see a video on his corolla, he was willing to turbo charge my mk2 golf 16v for around £2000 +VAT(4 years ago) was saying a basic turbo setup would run fine, as long as boost is set at a safe 4-5 psi...(HALF A BAR) or even supercharge it.
