I had a similar problem mate when i changed out my box for a jap sti version and it felt like the brakes where on when i pulled out of my yard,alot of binding going on so i went back to work after 500 yards and have replaced diff with sti diff and all's well.
I wouldn't like to say it would have been ok if i had driven further though so i wouldn't drive your's any more as it could have done severe damage already after a couple of miles!

Are you sure the box fitted is 752 and not 754? The VN is a UK box with a rear diff ratio of 3.54 ie. final drive of 3.9 and drop gears ratio of 1:1.1 giving rear diff ratio of 3.54.
The ty752vb4aa box looks to have a final drive ratio of 4.11 with 1:1 drop gears giving a rear diff ratio of 4.11.
So looks like these guys have no idea what they are doing and you now have a mismatched box and diff. The upside is an R160 3.54 rear diff is prob the easiest to get hold of all UK newage cars and the late UK classics with TY754VN... boxes all have 3.54 rear diffs.
