Rb26 Headstud Length Needed

[ezy_09s]

I am trying to find the stud length for an rb26 ..i need an overall length of stud and a length of the threads on each end of the stud.

I am trying to find an alternative to use on a gtir sr20 which uses the same M12 x 1.5 dimension as the rb26..which is larger than the regular sr20 which is M11 x 1.5.

I just need to find out the length to see if it will work.

And i am aware arp make studs for the gtir...but i dont want to use them if i can help it because they dont engage all the threads in the block.

I wanted to use another good stud other than the arp's(nismo/greddy/cosworth)etc..but i can only find them in M11 x 1.5 sr20 & its starting to piss me off

If someone could give me there stud dimensions & brand of stud they have it would be appreciated
