I'm into process of buying new forged pistons. For now it looks that I get the most for my money if I buy Wossner.
What do you guys think of Wossner pistons?
Also for those that do not know I need them because I have a head with 34mm valves and my current pistons can't handle that. I've sent an email to Wossner and got the following reply:
Piston kit Inlet Valve-Pocket Ø/ depth Outlet Valve pocket Ø/depth
9034Dx Ø36 / 2,6mm Ø31 / 2,6mm
9037Dx Ø34,6 / 5,1mm Ø32,6 / 4,1mm
9034 kit has 11.2 CR and 9037 kit has 12.5. Which one should I choose? I have head with bigger valves, some porting and cams. 34 has bigger inlet valve pocket diameter but is not as deep as 9037 kit whic has 4.1mm deep pockets but they are a bit smaller.
Also Stan if you could send me an offer via PM for your pistons.
Cheers
