I'm assuming that we're talking about the deeworks adapter kit here.
2.3 4cyl wc & nwc T5 input shaft bearings are very different (larger, wider) than the v6/8 bearing races and require the stock bearing retainer be turned down to the Deeworks retainer dimensions. You may need to add a spacer ring on what's left of the snout to mate up with the bell as well. Furthermore, the 4cyl input shafts themselves are a little bit too long on their own, and need snipping. There's a thread about this
here.
To my knowledge, there's no input shaft swaps that can be done to a 4cyl for it to accept a v8 input shaft bearing.
For mounting the box to the bellhousing itself, assuming you've got a ford pattern t5, the deeworks plate mounts it right up with no modifications necessary. If your t5 is muncie patterned, sell.
However, if you can get your hands on the adapter that requires you to turn the bellhousing and use the ford throwout bearings, you're good to go if you circumcize that input shaft.
For the driveshaft, if your car isn't lowered too much if at all, go with the yoshifab one piece adapter. If your car is lowered quite a bit, fatadams has the right idea with a custom 2pc.
It might also be a good idea to have adjustable torque rods, for setting pinion angles.
For gear ratios, throw that t5 into the ocean and get a v6 or v8 spec one lol.
The first is a stump puller near-identical to an m47, gap to second is slightly shorter, same with 3rd. Fourth is 1:1, and od is just a hair longer. During normal driving, I don't think you'd feel much of a difference.
Joking aside, try the ratios on it and see if it's adequate for YOUR needs.
tldr, if you don't have easy and cheap access to a lathe, recoup costs and buy a v8wc. If you do, neato, give it a try.
I hope you've got a way to bolt the trans onto a crossmember, and good luck.
