As this car's purpose has changed somewhat, besides the bits I've already mentioned, I'll be adding a thermo-switched electric fan to keep temps under control in less then perfect racing conditions.




More to come....... :D


key part to getting the fan in, and operational is the proper parts. Below is a coolant inlet for an AE82. This will bolt in as the stock one does, and is even pointing in the correct place. The original Toyota switch is grounded, and when hot it breaks the ground(opens) and the fan comes on. This works as a safety as well, if the switch breaks, the fan stays on.

For Racecar I'm using a Honda switch, that will be open, and close @ temp (reverse of Toyota switch). This makes wiring the fan a bit simpler since the Honda switch is more conventional in operation.

BUT... the sensor doesn't quite fit. The hole for the probe is too narrow, and the threads aren't deep enough. So a few mods....

Image


and the Honda switch becomes right at home....

with just enough of the sensor in the coolant to operate, yet not so far in that it seriously disrupts flow

Image



more to come..... :D


I'm getting ready to wire up my e-fan and would love a more simplified system. You should let me know how this works out, because I was thinking of doing the Toyota "normally closed" method initially.

So this car doesn't have traction brackets? Are they illegal in SCCA?

What is the deal with the rack? I don't see a reservoir, and didn't see a mention of it in the book. I highly doubt someone would "de-power" a rack in an official car..

not illegal in SCCA... but illegal in the ITA division - think of it as a "stock" class. The car was always a non power steering car..... there are a few other "official anomalies" in THIS car..... :o some to be revealed ;)

Wow! I've never seen a factory non-PS AE. I knew they existed but I figured they were all dead.

Thanks for shining light on ITA as well. I really want to enter either of the two, but I always worry I've modified the vehicle too much. Honestly ITA seems impossible for the (stock) 86.. But I'm sure someone is up to the challenge :)
