If you want a blower like a 6-71, or an 8-71 you can pick them up off of ebay for about 200 bucks if you look around (the 200 dollar one's being off of older detroit/GMC trucks)

Then you just buy a snout, and new backing plate, and an intake manifold from like summit, and wala, it's blown :-)


Or if you want a turbo, your best be is going to be building your own exhaust manifolds (if you want twins). Otherwise if you want a single turbo set up, I have seen people take a set of headers that are ment foe an open drag car, and they just run straight forward/back. And you collect it in the front of the engine. And put on a big turbo right up front.

Or if engine bay room is an issue you can also put the turbo in the back of the car, but the loss of thermal energy will cause lag, and you will have to run a smaller exhaust AR size, which will make a larger back pressure in your exhaust.

If I were you I would just use a 6-71, or 8-71, because they are much easier, and much cheaper. Putting a snail under the hood costs a fair amount of money. I know, I'm putting a TO4, on my toyota supra engine, and it was already turbo'd, but it is still turning out to be quit expensive and time sinsumeing, because we have to build out own exhaust manifold.

Anyways, a blower is cut/dry, and been done alot, so it is much easier if you get an old detroit SC.
