On top of any of those options I'll be adding alum radiator with electric fans, walbro 255, sr injectors, and bigger maf. Possibly better tuning, but I thought mine was pretty decent for just a fuel controller and 8 psi. around 14.5 afr cruising, and 12 under boost.

do not buy a manufactured engine. You will rest assured not to crack or break a ring land with aftermarket pistons. if you are on a really tight budget, do the following. (not in a any particular order)

1. Purchase forged pistons of your choice and compression ratio
2. have your stock rods and crank checked for straightness, cracks, etc...
3. hone/bore cylinders and deck block surface head
4. rebuild the head if funds allow
5. ARP head studs
6. aftermarket head gasket of your choice
7. assemble with bearings, gaskets, etc.....
8. all the fuel upgrades mentioned....

this build will not safely break any hp/tq records but will surly hold the 12psi without blowing a hg or ringland...
