Thats a joke. How can A GSR be the same price as Ls or B16A? What about rods or pistons. Justa place throwing an ad on E-Bay. It costs every bit that much if not more to build a serious sleeved motor. A word of advice. You can build a motor faily cheap if you stay under 300whp. If you want more and want it done right and for it to last a little while then you need to spend some $$$$.
