300 hp slant w/turbo... suggestion

Iam Intrigued at the thought of a turbo six. When i first kicked around the idea of what to do with my valiant, i made a pro/con list of 225 cu.in. Or V-8 swap. Was originally thinking LS swap. Lots of LS motors powering all kinds of cool cars.
All the while when people ask about the car, invariably people will also ask; "does that have a slant six?" Every one remembers these motors as chugging on long after the bodies fell apart.
I realized then, that this time around i was going to power my car with a turbo. How wild it will be when you pop the hood with a turboed slant?
Collecting parts now, as cheaply as my patience will allow, and reading this forum to learn.
