Used Perrin 3" showed up today, needs some cleaning but is in good shape.
Finalized the dual thermostat to intake manifold and KPower Miata water outlet
Connected the wiring harness, threw in the intake manifold, and intake. I scratched the intake tube up being a gorilla, unfortunately. edit: it is paint transfer, I can save it
Front bumper back on
The couple of hose couplers I ordered will be here tomorrow so I'll figure out my right hand side coolant line tomorrow, get the header in, and hopefully start it this weekend.
