However, in relation to his answer, yes the will physically bolt up with each other...
Well the bracket that mounts up to the engine is different yes, but the motor mount itself is the same. Sorry should've specified.

So it is only the pistons and the flow passages in the heads that are responsible for the compression differences in the two engines - otherwise the engines are the same (aside from the engine mount bracket too)?
LOL - Sorry, but which of you is right? One says rods are different vs same etc... for other parts too? HUHH?
Rotating assemblies? Meaning pulleys or what else?
I don't know.... perhaps this is from inexperience, but it would seem to me swapping in an already ready to go TT engine would be a hell of a lot easier/cheaper than modifying and upgrading every single part on an NA engine to make it a TT converted. From what I've read the consensus pretty much is that you are better off just buying a stock VR4 and modding it vs converting to a TT from NA due to cost/labor.
