    Yes. Swap out the block and leave all the top end stuff from the M20b25, thats the quick and easy way.


    Id be a little better with an SETA block but you got what you got.

      I made this a sticky at the top of the page for a reason. Search before you post, ANYTHING you can think of has been covered time an time again.

        To be perfectly honest, this swap isn't worth doing, with the possible exception of a turbo. But either way, unless you bottom end is dead you wont make more horsepower, just shift the torque lower and have a less efficient engine.
