A mate removed an rb25de from a 93 cef last week and it had blanking plugs where all the oil and water lines fit up. If thats not a turbo block, i don't know what is.

Different pistons obviously, to raise compression. Without removing the sump i'd say there's a fair chance it has provision for oil squirters as well, though most likely they were blanked off.
