Having played with turbo 4 cylinders about 25 years ago, I know the amount of extreme power they can make. But it ain't CHEAP by any means. And I don't care if you get your turbo for free. You have to have a drive train to handle the power, and the safety equipment to get on the track. But I do love boost in many situations.
All in all, I am a N/A guy. I like simplicity under the hood. No clutter. It's why in almost every classic car, I install manual steering, manual brakes, and no A/C. A single fan belt and tons of room makes the engine bay a happy place.
