how do i know that i have a GTR crank

[sweetr33]

I have bought a RB26 crank along with some other goodies, was wondering if i can check somehow that the crank is a real gtr crank and not just another gtst crank??? We looked for some numbers but couldnt really see any. Any help?

measure the stroke, also the bolt for the harmonic balancer is larger than the gtst one

[sweetr33]

ok so anything else? i will try the harmonic balancer bolt one first.

out of curiosity have u done this to ur car and thats how u know about the harmonic balancer bolt being a different size??? Is there any number stampings that would set it aside from the rb25 crank??

put your rb25 bolt in the cranks thread it it bolts on its an rb25 if it fits in loose its 26 , rb26 bolt is a bit thicker .
