Hi, I have a 1977 3 lt. turbo no modes only euro exhaust.
Does anyone know what the compression on a stock engine is.


thanks

Factory manual says 6.5:1 for type 930/51 & 930/53 motors.

The 3.3L's run 7:1 stock, but they're intercooled...

sorry I should have been more clear. I have a 930/52 engine. I would like to know what the compression test numbers are,? not the compression ratio.

Thanks
