A small update after a Summer of getting nothing done.
Except for the alternator and starter power wires everything is connected in the engine bay. I have about another 12" of wire remaining that needs to be covered on the main branch but I ran out of electrical tape. I also need to shorten wires that run to the transmission about 6" but I think I'll do that with the engine out.
Yeah I know the loom is ugly and kind of sucks. As long as it keeps the wires from getting wet/toasted though. It doesn't have to be pretty; it just has to work!
I've also gone ahead and purchased just about all the parts I need to rebuild the engine. What $2000+ in parts looks like:
Picture includes but isn't limited to: RX-8 stat gears, NRS ceramic apex seals, Mazda OEM seals (except apex seals and with FD corner seal springs), gaskets, etc. RX-8 e-shaft will also be used but it, along with all my other rotating parts are at Mazdatrix being balanced.
