225 turbo headers

The biggest expense I keep running into is no off-the-shelf pistons. Sure, the stockers are good for 200-250 hp, but that's normally aspirated range. Increase boost, and there is no way they will last. The Wisecos have too much deck height for a turbo application so we're back to $100 each for custom ones.

Second is tuning. Blow-through carbs are a terrible idea. I know you guys are running one, and there are others, but it's a hack. Add in the built-in mixture distribution problems of any 4bbl manifold and it's a holed piston waiting to happen.

The best option is an EFI system.

Sure guys can cobble together a junkyard bomb, but serious, reliable power (like 400-500 hp) should be attainable only with EFI and a large enough turbo. And lots of tuning time on a chassis dyno.
