now i have 40mm inlet and 34mm outlet valves - its a g60 with boost, so i was thinking about only getting bigger exhaust valves, 36 or 38.. in combi with the 41 inlet, it gets very tight between the valves - do u think it makes a big difference (performance) between 40 and 41 inlet valves??

thanks for the link jeri! hp is looking good, i hope they speak english or a bit german.. whats about szuromiracing, Kacsó-Gép or frenky-tuning?

 

hi! i'm searching someone in hungary who can port (tune) my 8v G60 cylinderhead.? best would be near to austria, budapest is still ok.. i dont need anything special, only good work and not too expensive

thanks, greetz tom
