They do 8:1 pistons now? I thought Wiseco only did 9:1 for the 3SGTE.

Yes mate- 8.5:1 out of the box for the 5S block, final CR was closer to 8.3:1...race fuel will help me run lots of boost

Just checked my accounts.
Not Wiseco, Wossner. 
Re: CP Forged Pistons
Yeah- it looks like you could get them from Wiseco, but it would be a "custom" order....i.e. $$$$$$$$$$

They all will do any compression you want.
Almost every engine I have built has had custom pistons.
The C/R is the most important part of the engine, get that wrong and the engine will never run correctly and give the best power output.
The higher comp pistons come from the USA where they use E85 and race fuel
