How can you tell its an RB25det?

[RBkillsall]

I need to know on how to recognize an RB25, I have heard people get scammed into purchasing an RB20 and thinks its an RB25. i dont want that to happen to me.

I am thinking about purchasing a 240 w/ an RB25det swapped into it already but i need to find out on how i can tell its a legit RB25 so that i dont buy some other engine.

Ive noticed that the RB20 and the RB25 looks identical to each other, thats why i posted this up, so if you have any suggestions or advice please feel free to post it up and also if you can post up pics too, that would help out alot.

Plz for the people who have done RB25 swaps or own RB25s, help me out with my problem before i screw myself over.

umm off the top of my head, if you check the coilpack covers of 25's it will say NISSAN 2500

left hand side of the block it's stamped towards the bottom rear by flywheel. it reads rb25. thats the for sure answer. the timing covers are stamped rb25 as well.

The rb25 has a flare out on the front timing cover on the intake cam for vvt. Valve covers are humped on the rb25.

The timing covers are stamped? I thought that was only the 26? My 25 sure isnt stamped.

what?

they are NOT stamped on 25's.

where the stamp is on other RB's the RB25 has the VTC hump.
