well you start off with this.. i was doing some research and if you use pm7(jdm ZC) pistons in that block and the z6 head with I,H,E 68mm throttle body, skunk 2 intake mani and adjustable cam gear that d series will make more power then a lightly modded b16. start with that and work your way up! d series blocks are dime a dozen.
with this setup you will yeild around 150whp and 111wtq for under 1k
