BE CAREFUL WITH THIS STUFF!! -- He (I assume) means with a turbo, not fuel injection. Adding FI would be of greater benefit than the turbo in the long run. This is because FI does such a better job at metering the fuel and "monitoring" the engine's constantly changing demands. Also note that the after-market turbo systems will bring a quick end to a good stock motor. If you double the HP you have ALOT of beefing up to do -- Very true! Blowby would be of concern as well as stress on the connecting rods, crank and bearings (journals?), just to name a couple of problem areas. Heat buildup in the engine bay would increase and that's not cool for our type of engines. With the forced induction you are actually increasing the compression ratio and I KNOW that causes an increase in operating temperatures. Then you have to beef up the tranny to handle the power. Better clutch would be a good idea as well. Going that much faster? Better beef up the brakes and suspension. Shall I go on?
