Mahle Pistons

[Bubba]

While rummaging around in my mates workshop i came across 4 shiny new pistons...i was told that they were irmscher sport pistons.

basically you bought them from mahle and irmscher used them as the high compression pistons for the 1.3. Said that you could put them into a standard 1.3SR block and it would up the compression to that the same as the sport...or some **** like that.

Casting part no is 75P39 if anyone wants to know :)

erm the "sport" CR is going to be the same as a normal 1.3 engine anyway lol
