R33 engine code question

[Nameless EJ6]

I have an RB25DET engine.. but the code on the block only says "RB25"

Is this the same on all RB25's? Is there no "DET" ?

Thanks

I think the blocks are the same on the RB25 / RB25DET - most of the differences are in the head / cams etc...anyone else confirm?

I'm thinking it's this way on all R33 GTS turbo engines.. because they are the same block. The pistons must be different though because of it's rated compression.

not too worried because my engine has obviously always been turbo.. I can just tell by inspecting it.

Just adding my $0.02...

My R32 GTR has just "RB26" with the engine number stamped beneath that. Obviously all the blocks are the same. RB20, RB25, RB26, RB30, etc, etc.
