turbo boost

[giog40]

Hey guys,

Can you please help me out?
I need  stock pistons for  g40 engine?

I think 1,5 bar is the limit the standard engine will take! anything over that is mechanical failure waiting to happen! I know you can run 1,2 bars all day long with a stock engine cause that is what my eatoned g40 was running for 5 years with no problem. I took the engine apart recently and it was just fine after around 90.000km on that setup!
