$450 chinese turbo and 600 plus HP(food 4 thought)

Hypothetically speaking, lets say you had the wrenching skills necessary to build a 600hp rat motor for $6700. With the astounding airflow potential of today's conventional Cylinder heads and the multitude of dirt cheap rotating assemblies cluttering up the Summit catalog, this caliber of HP per dollar heroism is certainly attainable----try hard and you could even do it with stock heads. Even though that would qaulify as an impressive budget build by most standards, how many people have an extra $6700 to throw around on anything let alone an engine, these days?
While that concept is like so cliche, we're serious about turning up the wick on dollar stretching performance. How does a junkyard 5.3L small block boosted to 550HP with a do-it yourself turbo setup built for $3089 suit your fancy? ieHOTROD
