26 w/ 25 trans, clutch?

[InsaneIan240]

So thanks to another member, I was pushed in this direction. Im still finding scattered information.

My question is what clutch do I need for an rb26 with a 25 transmission? People post the topic as 'rb 20/25/26' and then people answer without giving a specific engine, that they are talking about...

Second, oil filter? same as before. Ive found part numbers and so on...but nothing specific. There is just some doubt that the mounthing thicknesses of clutches for the rb series engines are different, especially if its a 26 engine, 25 trans. Same as the oil filter, obviously the transmission doesnt matter in this. but is the thread size/depth the same for all rb engines?

the other thing I cant seem to find is if there are any 'easy' visual ways to tell the difference between the 32/33/34 rb26 engines...

look at ANY build sheet for a RB26 swap, unless there cheap they have a rb25 transmission.

If it's a push type R33 RB25DET Transmission then you'll use a RB25DET push type clutch for your setup.

If it's a pull type R34 RB25DET Transmission from a NEO then you'll use a RB26DETT pull type clutch.

Of course we sell both type of clutches and RB oil filters
