This is an Isuzu board. While S-10s have been based on an Isuzu platform in the past, yours is not related to Isuzu in any manner.

I suggest you search for an S-10 forum for people who will be able to answer your questions regarding swapping engines into your vehicle.

One more thing, I really doubt you want to swap in any Isuzu diesel engine. While they are good engines, they are small, underpowered and now they are relatively old. The newest Isuzu diesel is going to be 20 years old. Most of them were non-turbo models, with the newest(only?) turbo'd model appearing in 87 Troopers.

There is a plethora of engine choices out there that will make you happier, be cheaper, be easier and in the end just be better if you are truly dead set upon swapping engines. For the amount of work you are looking at doing, you do not want to be shopping on the Isuzu rack for the powertrain.

Good Luck,
Michael
