Street, track, or dual use? What are your oil temps in the colder months?
I would definitely want thermostat control for a dual-use car. Track only car? Not so much. I've known people who drive street cars with coolers and they seem to have issues getting the oil up to operating temp in the winter months. I'm left coast so we actually drive our cars year round![Giggle](https://www.miataturbo.net/images/smilies/gay.gif)

RX7 cooler is good flow, good quality, and is a win. With the other ones and a non-thermostatic sandwich plate you could use a Michigan thermostat when you weren't on the track. Down here they call a Michigan thermostat a piece of cardboard over the opening of a heat exchanger. You could uncover the cooler for track days only. You don't really need it other times.

Yeah, there's a greater chance the rotary engine created the problems rather than the oil cooler.
I'll give you a for instance: If we put a miata engine in a F1 car (assuming it was possible), it would be much slower. Would you blame the brakes? Would you blame the suspension? No, it's the motor's fault, not the oil coolers.
Make sure there aren't any leaks, make sure the built in thermostat is opening, and run it. A good dozen members of mt.net are, and NONE have reported oil cooler caused engine failures.

You do realize that properly crimped fittings on hydraulic hoses are much more reliable... right? And if you can't figure out how long your hoses need to be without trail and error, you have more problems than just the obvious homophobia
BUT, thanks for the size recommendation, I'll go with an 8x13![wink](https://www.miataturbo.net/images/smilies/wink.gif)
EDIT: Now that my other questions have been answered, how about a new one. Has anyone found a need to run an Accusump?

I'd run an accusump if I had aero. I'm all a scared woman.

I'm not sure if it's worth keeping, I don't use it on my car and my temps are pretty bauce in the 103*f Texas heat.
Have you seen my oil cooler set-up? Why are you not complimenting me by duplicating it? There are two reasons I put everything on the interweb. One is to let everyone know that I and my car are better than anything they will ever know, the other is to help people out on things I've done before them.

I run a mocal fluid transfer pump from the sump through the cooler and back to the sump. Being switched, I can manually flip it on when it's time to race, rather than depend on a tstat. I save the mocal sandwhich plate for accusump to pressurize. I think accusump is worth it just for pre-oiling ability, definitely a worthy investment on a built motor.

I think they are yanking you ding-dong... a good solid soak with mineral spirits will flush everything out of the core and show leaks pretty quickly.
I have a used Setrab cooler from one of the Realtime Integras that used to run Speedvision World Challenge back in the 90's. Its still in my garage somewhere with a broken mount from a front end bump. I wonder if its still good...

Slightly off-topic
What is the general consensus on engine coolant oil "coolers" like you see on a lot of OEM cars?
I know it cant be anything compared to an air heat exchanger, but do they do anything at all really? I have a suspicion that theyre more for warming up the oil than cooling it...

They are called oil coolers, but they're really more for improving oil warmup time than anything else. There's not enough coolant flow through them to offer any significant cooling benefits (IMO). What heat they take out of the oil goes into the coolant in the mixing manifold anyway, back into the engine, so there's no net heat loss from the engine.
My oil temp sender is on a sandwich plate on top of the OEM heat exchanger. While the engine is warming up oil temp lags coolant temp by about 55*F.
I'm thinking now I'd rather have my sender in the sump, since the temps I see now have always been affected by having passed through the heat exchanger immediately prior (so the temps I see will always closely track coolant temp).
