My friend bought wet NOS(the brand) kit from UK(fucking cun the NOS kit....come in 4 small bottle...the bottle as big as big coke bottle and only for blardy 2.5k) and want to fit into hos GSR engine.....the problem is he dont know whut to strenghten in his engine for the power upgrade. He ask his mechanic what to do and he said change conrod and piston head....me and him have been going around sunway and ask for piston head for gsr but it seems none.....and does this modification sufficient enough to withstand the NOS and turbo let say around 1.3 bar.....any sugestion where to get the material and to toughen up the engine..???
