Paint them black if you are worried about being cheaty. The number one thing that will ruin your weekend with a rotary is if you overheat the thing. If you overheat it, the first tool you need is an engine hoist. Replace with new the two main radiator hoses and cap off everything else. Add big bright LED warning light for low water pressure. Have a mechanical water temp gauge. Get a bigger radiator if you can. I *think* an 83 has the beehive oil cooler under the oil filter. Ditch that immediately and convert to the earlier or later style radiator type cooler. I cannot stress enough how much of your effort needs to be steered towards keeping that thing cool. If you keep it cool, it will last indefinitely.
Thank you for the quick response,
I have looked at those hoses and the lower hose looks the same as the one can get from local stores so maybe my that came in the car is not stock and it is why I have a kink.
I do have an under the oil filter cooler already and will be installed shortly and thanks for confirming that it is the correct thing to do.
I have purchased a low water pressure sensor and i will be installing with an LED and buzzer.
Some more questions:
Do you run an electric fan and if so what brand and size are you happy with?
Have you replaced the water pump and what brand do you use?

I think you may have misunderstood me. The beehive/under the oil filter type oil cooler is junk. There's a reason why it was only used for 1 year on RX7s. You want the radiator type cooler like this https://www.atkinsrotary.com/store/w...-750Detail.jpg
Your profile says you are in CA. If you are near OC, I can give you one of mine. Was told that the rotary gets more cooling from oil than water so you want as much oil cooling as you can get.
In regards to your other questions, I have an FC3S/2nd gen which is different than yours. I do run an electric fan. I forget what it came from but I think it's from a Hyundai/Kia I picked up at the junkyard. Seems like the South Korean fans have a real low current draw. It only gets used when the car is stationary or coming into the pits. At all other times you are moving fast enough that the fan doesn't do anything. For water pump, I've always used the stock one. The only issue is that it cavitates at high RPM. To offset that, I bought an underdrive pulley for the eccentric. I got mine secondhand but Racing Beat and others make them. What race are you planning on running?

Sorry for the confusion, we have 2 RX7s, a 1982 and 1983, The 1983 was purchased from John Pagel I first purchased it as a parts car but it ran well so I have been building into a 2nd team car. I am planning on removing the beehive cooler next week since we have a extra stock cooler that came with the 82 RX7. 2 weeks ago I found a 85 RX7 dirt cheep with no engine and will be removing the "big bearing" front spindles shortly.
Yep I / we are in California and the team is from Bay area and Sacramento area. We have run 2 Sonoma races (Dec 19 and Apr 21) so far with our existing 1982 RX7, were you at those races?
Good info on the fans we have 3 pick-in-pulls in my area i will see what i can find. On the 82 we have no fan so during red flag times we have to turn off.
We are planning to be at the Sonoma December race with the 82 and hopefully with the 83
Oh thank you so much for the offer of the oil cooler.
I can't remember if we were at 12/19 Sears Point. Seems like a lifetime ago. If we were, it was either in the red RX7 (big sombrero on roof) or the silver/blue E46. Yes, we were at the most recent Sears Point. We won "C" in my silver Jag. We'll be at Buttonwillow with the Jag and I haven't even thought about December yet.

I remember a red RX7 at the most recent Sonoma race but not much of the first race. Congrats on your C class win. This is our team at the end of April Sonoma race
This was found it a box of parts that came with 1982 RX7 LeMons car and it already has a remote oil filter. I now have a 1983 with the beehive cooler and it will be replaced soon with a under radiator cooler so will need a way to mount a oil filter. Does any one recognize this and who may make and support it?
No, I don't recognize that other than it looks to be a mount for a remote oil filter that includes provisions for oil temp/pressure senders. I suppose you could use that to put an oil filter and cooler but haven't seen it done that way. The OEM non-beehive oil filter mount/base looks like the one in the link I attached. I used to have a bunch of these kicking around and I would think they shouldn't be too hard to find. https://mazdatrix.com/product/oil-fi...-92-all-short/

I have an oil filter base lying around you can have cheap, if you can wait a week for me to ship it. You will need two rubber o-rings that seal the base to the rear housing. Purchase four so you have spares.
I did a few for Chump now Champ. Yes your eyes dont decieve you. Drivers door is bigger. I moved the B pillar back 15 inches to allow easier egress. Rear door still worked.
I think this is for a remote oil filter
