will 09 topend fit the 2010 cases??

[KAWGRN]

Have a spare topend and thinking of adding a turbo to my spare 10 and was wondering as the 09 turbos better than than 10

No

The crank is different piston pins are not the same.

thought the pistons are cut different too, not something I would do and I don't know why some say the 09 is better, it was easier to tune, but many have figured out the tuning on the 10. Even bd figured it out, I think.
