Ive seen a turbo 1litre saxo and a turbo 1litre nova, anything can be, even the crappiest of engines can be simply turbod for not loads of cash, dont mean itl be all that powerful, dont mean you can run much boost, but it can be done.

Stu- T67? As in Trust/Greddy? They not that big, not really much bigger than a RS500 T4 so would probably boost before the redline, just, lol.
