i juat bought a datsun with an sd22 and cant find anything on them. but i heard they are the same as the sd33 but minus 2 cylinders is this true? cause there seems to be more info on the 33's do they have the same style injection pumps?

Kind of. They're about the same principle-wise. They do not have the same injection pumps; the SD22 would only have 4 outlets and the SD33 has 6 but they are the same type. But I believe that the pistons are the same size and quite a few of the internals are the same.

i know they would have 4 plungers but they can have the same modle pump still like the cummins 4bt and 6bt can both have a bosch ve pump or a p7100 just one has 4 and one has 6.

Not certain either way. I've only ever looked at the SD22 because I was trying to find parts for my SD33 before I had it rebuilt. When I didn't find what I was looking for, I stopped looking at the SD22.
