It’s been a while from the last update, but the build is winding down. That’s good, because I’ve put entirely too much effort into this.
I figured out how to secure the tires. Using some 1⁄8” steel angle ($30), I made some mounts.
When I first installed an aftermarket ECU (Megasquirt I) in my 1984 300ZX, years ago (almost 10 as of this writing!), I used the recommended GM sensor for coolant temperature. It required a bit of machining to fit the sensor, nothing major.
With my latest engine (and the two cars it was in), I decided to use the OEM Cylinder Head Temperature Sensor, since hey, why not? It was already there, in an optimal spot. All I had to do was make software changes to calibrate MS-II to it’s temperature/resistance curve. I had the data in the Factory Service Manual, all was well.
I finished up the tail light and signal wiring. I still have 4 LED clearance lights to place somewhere, but I’ll wait until I figure out what else is going on the trailer before placing them, in the hopes I can place them higher up.
So I’ve got this autocross bug, despite being a terrible driver. After about 5 seconds of thought, I came to the conclusion that I must get an autocross trailer in order to improve my skills.
So, after a bit of research it looked like item #90153 was the thing to get. The key is it has 12” wheels, whereas the cheaper one (#42708) has 8” ones. The larger the wheel the less RPM the wheel bearings see, which is good. The increased payload capacity and trailer height were just bonuses. Since I plan on hauling some wheels and tires and some tools, I don’t see coming near the 1000+ lb. payload capacity. And if you wanted to carry more, all you’d really need is some better tires, since that’s the actual limiting factor. However, I don’t recommend carrying anything near the payload capacity.
Note that this is one of the few big-ticket items you can use the 20% coupon on, so if you want to save $46 or so off the price, use one! I got it and built it:
I also picked up a trailer jack, LED lighting kit, 1-7⁄8” ball, and ratcheting straps from HF. From elsewhere I got a backup alarm, more LED lights, battery tray, some wire and a voltage gauge.
I then painted the frame and wheels to match my 280Z:
