ok this is pretty simple , cash is the thing over here
first things first, ir ur gearbox ratio up for the high rev ? whts ur ratio's ?
next , preparation for ur engine , head u need a higher band cams , stiffer valve springs so it doesnt float at high revs, next for head n block , u need really good race bearings or u just gonna sieze the whole thing up.
if u dint get wht i meant, open how stuff works n read the net , being a noob isnt an excuse to be spoon fed.
