Hey Tony l, sorry mate you have 4 different questions there, i cant answer them all though. You'd be better to describe what you want to do though so we can answer in context of your plan maybe??

Fundamentally the TD42s are all the same, ie. all bolt up patterns will be ok (i think)

In about 1994, i think, Nissan changed the TD42 internals and the rocker cover from a Silver top to a Black top. The Silver top is a more robust engine with heavier internals and thicker bore walls and pistons i think. If your chasing one be to Turbo then the Silver top is the one you want. Nothing wrong with the black top engine though.

The GU TD42 is the same as the Black top. the GU TD42T is an upgraded engine similar to the original Silver top. To the point that you can buy two different rebuild kits for the turbo and non turbo engine.

But your question is kinda left field mate, sorry. re the 3lt box????Um? Are you looking to do a conversion to a dead ZD30 or something? if you are then have a look around there are a couple of quality threads on here are dealing directly with the pit falls of that conversion.

Cheers MR
