The plan is to tow the Miata from my dad’s house to my house after Thanksgiving so that instead of hibernating in a cold garage all winter long, it can stay cozy and warm in my garage where I can begin the painstaking process of tuning the ECU as time permits. Our winters are generally much more mild and thus more conducive to working on cars. Also, we have a lot more dyno facilities in my area. The goal is to street tune the car. Then once the car is generally drivable and I better understand the ins and outs of Megasquirt, I will book half a day on the dyno to really dial in the tune.
To get the car for transport ready we replaced the old radiator which had sprung a small leak.
New Koyo radiator courtesy of @goodwinracing. I know everyone loves crossflow triple pass radiators for their high horsepower turbocharged track monsters, especially in hot climates. But my car is a 150hp naturally aspirated (mostly) street car that will only ever see 20 min HPDE sessions at most so this down-flow should be more than fine. I decided it was easiest to stick with what I had before for plug-n-play compatibility with my stock fans and custom coolant reroute hard pipe. My previous Koyo lasted 10 years. I expect to get another decade out of this one. It’s even got a more efficient “Hypercore” now with greater fin density than before. Contrary to Brian’s ad copy on the website, it isn’t made in Japan. Box says made in Indonesia.
Installed the hood (bonnet) and all new clips, elbows, hoses, etc. for the Suzuki Cappuccino windshield washer bottle that was relocated to the cowl area.
Installed new 949Racing end links to replace the old ones that had seized solid and adjusted them accordingly.
Drilled another vacuum port in the Golden Eagle vacuum manifold and ran a vacuum hose to it from the fuel pressure regulator vacuum reference port per Garry Polled’s advice.
