d24 swap from vwlt45 to volvo 740

[kurbads]

Hello, i have volvo 740 with b230ft, i use it as beater. About a year ago I rebuilded the engine, it was going great till now, engine broke once again and I am tired of fixing all the time, so I had idea of swaping d24tic in it, because I have heard they are more reliable. Around my area there aren’t any spare 7 or 940 diesel engines, but i have found couple vw lt vans that have d24t, so i wanted your help…
1) are they any different than the d24 that goes in volvo’s (mounting, specs and that kind of stuff)
2) what about transmission? do I need to buy transmission from other diesel volvo or my m46/od works fine?
3) is it even worth?

I’m quite new to this,
Hoping for reply
