I had a little under 500 HP in a 3400# car, and that thing was nearly undriveable at speed on any course without monster grip and years of driving experience, if you think a 2200 pound car with 800 HP is going to be driveable by anyone but the most experienced F1 racers......................... Please be realistic, learn to carry your speed with the power that you have, that is how you will be a winning driver.

Even a V8 would have to be very healthily built to put up with that kind of power, your transmission, well sounds like you want a beefy TH400. You'll also need a monster fuel system, thats an obvious given though. I'd go with a V8 myself, broader powerband versus a Supra with a narrow top end. 800 HP with a broader powerband = a faster car overall, and more fun to drive. Your asking for roughly 5.48HP per cube, that is no small feat by any means, but the engine would be very peaky, again, not my idea of a fun car to have power for 1500 RPM only and the rest of the powerband sucks, no fun.

Way too broad a question, NA, Turboed, pump gas, what kind of ignition, and of course as mentioned HOW MUCH MONEY. You could spend $1k-2k on a computer setup, $100-$500 on exaust, or more, $1500 on a top end, $3000 on a bottom end........ How much work will you do yourself, and what are your realistic goals, and what kind of powerband are you looking for. Since your planning to daily drive it, you probably want manners, so be reasonable. If you want real power, in any form, I'd pull the engine or get a spare and at least rering it, fresh bearings, new seals all around, rebuild the top end (springs, rockers etc), throw a cam in it, ported heads, etc all kinds of possibilities, but again the question is unanswerable. The sky and the dollar is the limit.
