do what I did. get a inline pro head gasket and block guard. pick up a AFC, 450cc injectors, fuel pump, fmu, and missing link. get it tuned. import parts has a new deal that you build your own kit online and only by the parts you want/need.

if you want to go all motor and have good power:

11.5:1 comp pistons
eagle rods
sleeve the motor
a good valve train and Toda spec c's and that should put you at about 4500 bucks or so depending on where you buy your parts. of course you will still need enginemanagment, but you can make 200whp all motor on a AFC pretty easy. on the other hand I know you can make 400whp on a AFC, fmu, and 450cc injectors without ever touching the sleeves, pistons, or rods. it is your call
