My sr20det block From Bluebird vs my sr20de block From 200sx se-r ?

Is it the SAME block, casting ...?

I mean, is all the oil and water lines (in the block) be at the same place?

I project to drill and tap, at all the same place from sr20det block,
to make fit my t-25 manifold and turbo(t-25) on my sr20de.?
