Another advantage of the 200R4 is the gear ratio spread is better.
2.74 first gear, 1.76 second, 1.0 3rd and .67 OD. Closer gear ratios provide less RPM drop during shifts. The taller OD is a slight benefit too. This being a smaller trans, fitment and lighter internal components for faster acceleration are helpful.
ONE drawback: The trans pan on the 200 is looooooog, putting the trans mount back much further. This poses a problem for the trans crossmember. You could fab a custom crossmember and tie it to your subframe connectors if they are fully boxed and welded.
