2,0 -> 2,7 in 901/03
Hi there,
It is quite common to bore the Cylinder spigots from 92 to 97mm to insert 90mm barrels into a 7R mag engine case.
Actually i have got here a 901/03 (some 1 or 2R) and the idea came up to upgrade this one to 2.7L.
To me the contact surface where the cylinder would sit on would appear a bit tiny plus the pressure on the copper ring would probably be exceeding.
Question: Did anyone do such conversion on the earlier mag cases and if, what are longterm experiences?
Cylinder/Case oil leaks?
Cylinders "sinking"?
Thanks,
Robert
