GSR heads on an ls/vtec

LOL- no he doesn't.

An LS/VTEC is little more than slightly stroked GS-R. By using a B17A crank, he's actually destroked the engine, decreasing displacement. This does, however, drastically improve the rod ratio- I have no doubt he can rev to 8200 all day long with no problems. His displacement is also identical to that of a B17A- 1677.8cc. A far cry from the 1834cc of an LS/VTEC. And he's not using stock rods with a B17A crank in a B18A block- the deck heights are different, so he would have to get custom rods made to run that setup.

Hey is not running stock ls rods but he has b17 rods and pistons that were balanced along with the crank shaft. Also he had his cylinder walls resized and the head has been decked to support higher rpms. He has kinda just made a b17 gsr with a 98 gsr head.
