I'm removing my omp, and oil injectors and running premix (obviously).
My question to you guys is, what thread size and length are the oil injectors on a series 5??
I know i saw it on reTed's site before (fc3s-pro.com) but his site is down, and I don't really want to "eye" it. I'm afraid that carbon will build up in there if the bolt is too short.
I'm asking specifically about the series 5 rx7, but if someone knows the thread specs for other years, go ahead and post em up, maybe I can save someone the effort.
FYI I did a bunch of searches to no avail

(it is rumored that the s5 engines didn't last nearly as long as the s4 counterparts because the electronic omp would fail, bringing your engine to a premature death.

If you don't want to go and buy new bolts just cut the oil injector lines close to the injectors and call it good. It worked for me. No leaks or anything.

well i found bolts that would fit perfectly (m10 x 1.25 x 20) but was informed of the difference in accuracy of machine bolts, and automotive grade bolts. Long story short, the identical machine grade bolt (I could only find machine grade) doesn't fit near as tight as the oil injectors. I think I'm just going to cut the nipple off the back of the injectors and hit it w/ a spot weld, then sand to smooth. You guys think that would work well??
I was just thinking of sealing the outer part of the injector, should I weld the hole on the bottom shut as well??
