3.3L turbo cylinders on 3.0L NA

[Aurel]

Has anyone ever considered using 97 mm 3.3L cylinders from a turbo motor in a 3.0L engine, making it a 3.3L NA motor? Of course this would require higher compression pistons since orginal CR was 7.5:1, but we already know the cylinders will fit since the cases were the same. Any downside to this idea?

The 3.3 cylinders are only finned on one side...most people convert to fully finned cylinders when rebuilding the 3.3's as they cool better/more evenly.

You need the crank and rods to do it.
Cylinders all fit the same hole in the case.
The 3.2/3.3 has a different size wrist pin than the 3.0.
95mm cylinders will open to 98 for more cubes.

Right, I did not realize the stroke was longer on the turbo motor. With 70.4 mm stroke, that only gives 3.12L, not really worth it. But this brings another question: Do the longer rods fit the 3.0L crank directly, or was the crank different too?
