So i heard about the sleeves in the H22 sucks? , is it better to use the ones from Type-s lude H22? or go for aftermarket ones? What about the pistons and rods? , were can we draw the line , can anything of the original parts be used in the bottom end , or do i need to change em all? I guess when wanting more HP i need to raise the comp rate as well..possible to run it at 12:1? , and what would it help me..higher revs? Pls write what u done with ur N/A H22Â´s to get em more powerful..
