We're how many posts deep in this thread and you haven't had one piece of real input or anecdotes concerning the subject at hand except to find a link to the V8R kit in their horribly set up website? (Thanks by the way.)

I mean really...

But let's go further down this rabbit hole:

1) F2T will bolt in
2) I don't need to make an oil pan
3) Intake manifold is easy mode, and no, i won't be doing the welding myself.
4) Fact: having to fab a rear transmission mount > having to fab rear transmission mount... and an entire ******* rear diff mounting solution for a diff nobody has used on a miata before.

Well. Yeah.
