Intake side should be M8x1.25 or M8x1.5, which you should hopefully be able to find at a local ace hardware. You should have mentioned needing some last week though. I could have pulled them from an old head I have and dropped them up when I was up near Annapolis.

Well, I was able to make a bit of progress today. Got the oil pump, (HUGE thanks to Emillio @949 racing for the quick responses and shipping on this BE oil pump), water pump, tensioners, Garage Star pulleys, timing belt, ATI damper (which was a pain in the a$$ to accomplish), head torqued down with ARP head studs. I need to get my coolant reroute ordered so that I can get it installed before I finish the timing, cams are currently loose and not timed correctly. But all in all it was a good day and I finally got to mock the turbo up. Feels good to finally be doing something legitimately productive with this project.
Pics!!!

Lol, Yes Payam, I know I need the freeze plug, all of that is part of my next purchase.
And Ryan, I considered heating it up, instead just ended up getting a damper installer from the parts store and used some grease on it. Apparently ATI has made a revision to the size to make it easier to get on, I suppose mine didnt make the cut lol

Are you absolutely certain that it went on all the way? I tried it like you the first time. You could not turn the wrenches any tighter on the installer, it was still 1/8th inch away from full install. It will instantly ruin your timing belt if it's not all the way on. Moly grease is a must. It sounds ridiculous, but the other greases can't take the pressure of an interference fit.

Well, I came to the conclusion today that my project would not have progressed as far as it has without the knowledge and support of this forum, so I took the plunge and became a "proud supporter". So thank you

Awesome build, looking forward to some final numbers.
Would a 50/50 mix of E85 and 93 be of any benefit as far as helping keep denotation down? Not trying to derail your thread but you are the first I have seen do a 50/50 mix with, what looked like, very high success. Unless I read something wrong and you did a 50/50 water/meth injection on pump gas.

I'll research more into it then. I am running a somewhat aggressive timing map and with my winter tune on the car I am getting a bit nervous as my IATs are starting to climb higher than I would like. It would be more for piece of mind since E85 is easy to get here. I don't have enough injector/fuel pump to really push higher numbers out of the motor yet.

It had its benefits, but that situation is the sole purpose behind me utilizing a flex fuel sensor with the Miata build here, I want it all to be automatically adjusted on the fly based solely on fuel content. If you are attempting to minimize knock, and doing a flex fuel sensor is not an option, meth is a relatively easy solution that remains consistent. Failsafes are key with meth setups though.
Hopefully this answers your question.

Well, I hate to give everyone blue *****, however I just got a job opportunity for a 12 month vacation to Afghanistan, and the pay and professional growth is rather difficult to pass up. If I choose to accept, I will be leaving late Jul- mid Aug which means the project would take a long nap until I return :( Hopefully I can at least get the engine and subframe back into the car for ease of mobility. I will obviously post updates as things progress.
