LS/VTEC

if you want it RELIABLE you must do AT LEAST THE FOLLOWING IMO.

Tear down LS block, bore and hone, BALANCE ROTATING ASSEMBLY.
-YOu cannot bore a FACTORY block past 82mm. If you want 84mm+ you have to sleeve it, that makes the block a 2.0 with that big of a bore.

Sleeving costs $1000 MINIMUM

IMO, Throw PR3 pistons (B16), ARP 2000 series rod bolts so you can rev it to 8500rpms. Rod bolts are the weak point, not the rods.

with a GSR head your compression will be like 11.5:1+
