Haha.... you're OBVIOUSLY looking for suggestions,thats WHY you're here. If your feelings are hurt because of what people have to say then you're on the wrong boards.
As far as turbo'ing a City, I don't see a reason why it can't be done very easily. Besides the hardware and the plumbing required, the fuel map can be handled with something as simple as a Map ECU but if you're looking for something that will give you timing control then you're going to have to invest into something more serious but it is definitely readily available. Distributor or less has nothing to do with any of this... Supra TT's do NOT have distributors which are infamous for making ridiculous amounts of power. With the current setup and the compression ration, you can still get away with boosting but the amount is very limited to maybe 10-12~psi, depending on your wideband reading of course. You'll need to replace your head gasket with a higher compression one to raise the boost but I doubt you'll be doing any of this without spending some "serious" cash.
