I've had a few turbo cars and a couple with SC's. It is so much easier and less costly with a working platform. Turbo cars do make more power than one with a SC as they do not take power from the engine but have some lag but less as technology improves. Take the Crossfire, i have an SLK32 AMG, and enjoy reaching a high 11 a that seems to be the target for these cars. Of course you can always call them and ask what happened with that car.
Quickest car I have ever owned was a '93 eagle talon tsi, AWD, 5-speed. 1.68 60', 11.68 in the 1/4 with a trap speed of 122. None of the big block cars I owned came close to that and the entire motor rebuild was $4000. Tunes adjust timing and fuel. An AFR gauge takes care of the fuel needs and of course their is the timing. Mitsubishi offered DSM link, a tuning chip for $500. that did a lot.
Enjoy what you have and weigh the mods against the buck. When you get a new platform look for a car with a turbo and go from there. these cars are still a blast to drive and if you hit 11's that is quick compared to the big blocks of the past.
