Rover 220 Turbo Engine

Putting aside the fact that the engine from a 220/420/620/820 turbo is crap, too heavy, etc… Will it actually fit on a VHPD gearbox in a exige?

Think it’ll bolt up to the gearbox because I know the 220T used a PG1 gearbox. I’m ASSUMING the input shaft splines/length are the same for all variants of the PG1? Ratios might not be the best matched though.
