Are there any aftermarket oil coolers that perform as good or better than the stock FC coolers? Just wondering if I could make my oil, cooler.

Firstly, very few aftermarket oil coolers are as good as the stock FC one. Unless you're building a very serious turbo engine, there's no need to upgrade it.

Secondly, do you actually have an oil temp problem? If you do, it's most likely because of a fixable problem, not lack of cooling capacity. If you don't, why would you want the oil to run cooler? It works best at certain temps, so you don't want oil that's too cool.

Don't waste money fixing a non-existant problem.

Fluidyne makes an oil cooler, but i wouldn't waste the money unless you liked it for its shape/size. they run them on Formula Mazdas (carb'd stock 13Bs).

PWR in Australia makes aftermarket ones also..

more effective better looking etc.

may be worth checking out.
I'm looking into one as I can get a different shape ans stick the cooler in a different place.

i just looked. pwr makes a cooler just for us. emailed some companies to see how much it costs. i'll let you know.

There is an "MFR" (Mazda Factory Race) unit that's supposed to be superior than the stock unit.  Racing Beat sells them outright to any consumer.  This is the same unit that Mazda Comp/Mazdaspeed sells to their competition members.

Drops right in with very little fuss...

Ted are you sure it is a drop in affair? I thought I read in their catalog that you have to mount it yourself.

Maybe they mean for non-RX-7 app's

Sorry if I'm stepping on anybodies toes here or taking over the thread but I've got a few questions. I've got a fairly heavily modified s5 TII and am having a problem with my oil thining within 1000 miles of changing it. I'm currently using vavoline 20w50 vr1 oil. I was wondering if anybody has done a dual oil cooler setup? Also do you think there is a problem with my car? I have brand new engine, flushed my oil cooler, added ss braided lines to it when it was installed and would not like to have to replace it due to bearing failure from bad lubrication. Does anybody have any suggestions? Should I just get a better oil cooler or run 2 or stick with what I've already got? Any advice would be very appreciated. Thanks.

I've seen one, and I didn't see anything fancy in terms of mounting.  Maybe something relatively "minor"?

Hey dude, I would love to try and help you with this problem, but I think it warrants a whole new thread.

Can you start a new thread with this question?

sure no problem man. Thanks for your politeness(s/p).

The website says "This unit is not a bolt-on component and must be custom fit for your racing application."

It's still beyond the needs of 99% of cars here.

And last I checked, they were trying to charge somewhere in the ballpark of $600 for it. I pass.

US$858...

Thinning of the oil should not be a MAJOR function of heat. My 2 cents says gas contamination.

I've seen people run dual stock coolers.

BLK90TII

It doesn't smell like gas and my injectors, o-rings, and gromets are all brand new. I can't figure it out. I'll post this in a new topic so that we don't take over this guys thread.

fstrnyou

Yah, don't steal my thread..

BLK90TII

Sorry dude. I've got a new one. It's titled thinnig of oil possibly from excessive heat.

an oil temp gauge should be used long before money is wasted on trying to further cool the oil over what the stock system does.

fstrnyou

well, i didn't want to replace the lines and then find that the oil cooler was the reason for the leak. cause if i buy a cooler, i want to get a better one. but the better ones use AN fittings and then I'd have to buy lines again.

BLK90TII

The smae an lines should fit wahtever oil cooler you buy. You may just have to buy some new adapter fittings. Of coursre this is all depending on wheather or not you put it back to the stock location.

Icemark

Oil coolers themselves seldom leak unless the car has been involved in a front end accident or a mech improperly tightened the bolts.

The stock oil cooler is one of the best availble for any amount of money. I even use stock FC oil cooolers for offroad racing/desert Ford and Toyota trucks

dubrc

now correct me if im wrong, but i remember reading somewhere that the oil cooler is responsible for about 1/3 of the engine cooling...and with the high running temperatures of a rotary, wouldn't additional oil cooling be good thing?

NZConvertible

It the oil temp is already where it should be, then over-cooling it would be a bad thing.

The point is, it's a lot of money to throw into something that you will simply not require unless you're making serious power with a turbo or racing.
