A friend of mine has a 1994 altima GXE (KA24DE) 5spd MT. Hes been looking for the discontinued Unorthodox Racing Underdrive crank pulley. Since being discontinued he has been unable to find it anywhere and has wondered if its possible to use the 240sx pulley in its place. I did some quick referencing yesterday and found that they do use the same belt, or at least 1 of the same belts.

Getting to brass tax ... here is my question. Is the under driven crank pulley that is made for the 240SX compatible with the Altima? If this answer is "No its not." I would greatly appreciate WHY its not compatible. Everyone says "its not" that hes asked about, but no one has been able to come out with a reason as to why.

The only thing I think hes going to be able to do with it is get in contact with UR and have one made, which may require a "group buy" of sorts.

I was thinking that maybe the pulley would fit... but the altima uses a serpentine belt configuration(doesnt it?)... since they do utilize at least 1 of the same belts. At the cost that he will undergo with this pulley nonsense he could easily get a clutch and flywheel for his car, or even newer lightweight rims, which would be much more of a benifit than a simple pulley.


PS: PLEASE don't get started on how they use harmonic dampers etc. Thats not the nature of this thread. If you want to read about taht BS topic check here: http://www.grapeaperacing.com/tech/dampers.pdf for some REAL information. (they got some great tech articles too.)
