It would be better to build it man, it can be done just as cheap and you will have a stronger motor.
9.0:1 or 8.5:1 ve cp pistons w/ eagle rods. Go to Poor Boys Parts on ebay, he can get you the best deal on that combo setup I got my det pistons w eagles for $740 shipped
ACL race bearings 70.00 for the set of mains and rods
Because of the detonation you might have some damage to the cylinder walls and/or the top of the deck of the block and maybe head. So resurfacing and an overbore may be necessary. You need to tear apart the block and inspect it before ordering your piston/rod combo.
VET headgasket from greg $80.00
Golden Eagle B16a head studs, $100. Not necessary and you can use your stock headbolts but these things clamp the head down awesome. And they are cheap.
So other than fluids and some gaskets you can do the rebuild for $1000-$1200 depending on if machine work is necessary.
