Block them off with plates. Do it right and the added force will blow hard though the 4 remaining ports. I've also heard of people making a fitment piece that routes the 6 ports into 4 before attatching to the manifold. Don't spend your time and money putting a turbo on an N/A motor. Supercharge it if you're going to keep that motor.
The higher compression is actually a drawback, as it limits the amount of boost that can be safely added to 10 psi. You can pick up a good turbo motor for cheap, or you could buy a blown turbo + 13BT and send it off to be rebuilt by Kevin Landers for 1500. Get it ported and such for more power and it would be 1750
With the added power the N/A Tranny will crap out very quickly so that will need to be replaced as well. Personally I'd just buy a TII with a blown motor for 500 bucks and get it rebuilt.
