$330 without ducts

 

bump for a great thread

 

:-)

 

cool oil

is more important to the rotary than a piston engine, and of course mazda recognized this by adding another to the to-be-tracked R1-2, this thread re oil cooler maintainence is valuable.

if you take a close look at your oil cooler you will see that most of the fins in the direct airstream are mashed over, shutting off the airstream.

of course you can send it out and have it fixed by the Pros....


or

fix it yourself.

i recently switched to dual oil coolers. i did things a little differently. a friend had an FD that he was scrapping (rollover) and one of the few decent parts was the non R1 oil cooler. so i adapted it to the passenger side, bought some aeroquip fittings and lines and presto dual oil coolers for around $200 worth of hardware.

of course once i actually looked at my cooler and the other cooler i realized that i needed to pull some maintainence as many of the fins were mashed flat. i came upon the right tool hiding amongst my pick set. a spatula shaped, maybe 1/8th inch wide, pick.

i was amazed how easily the fins straightened. probably an hour and a half worth of light duty labor and the two coolers were looking good. 'great therapy, beats knitting. i was really surprised at both how bad they were when i started and how nice they were at completion.

my takeaways:

your oil cooler is in awful condition if you have driven your car.... the air ducts are located so as to catch all road debris. rotaries depend on cool oil. you can fix your cooler for no dollars. once finished buy some stainless steel 1/8 weave screening and affix it to the front of the cooler for added protection. oh, and add a second cooler.... the lowbuck way is snag a non R1 cooler and adapt it.

works for me.

That particular company does a FULL back flush with different sized screens. Basically they keep flushing until all of the debris is out, and they do it to an FAA specification. The spec is for a very small amount of particulate matter caught in a certain sized screen.

This is a REALLY good service if you suspect you had metal trash in your oiling system. No sense putting a new turbo or engine in after an oil system failure, just to have the crap in the oil coolers circulate through and tear up all your new bearings .

I sent a spare set of coolers I picked up off Efini7 to these guys and they just recieved them. It appears they their price has stayed the same the last two years

 

nice :-)

 

btw - if any of you ever lost an engine to bearing failure, it might be a good idea to get your oil coolers drained and cleaned by this place so that any of the contaminated oil doesn't get recycled back into the main flow.

 

What was the turnaround time?

 

I want to see pics when you get them back!

 

They just received them on tuesday and need to evaluate them. I was told 7 to 10 days approx turnaround.

I'll have my R1 coolers available for sale soon if anyone is interested, I bought a spare set to have them refurbished so that my car was still driveable during the process. Not sure why I did that, being as it's winter here in the northeast and my FD is stored in the batcave, lol.

 

Hey Rich,

I might be interested in your present oil coolers, one of mine is cracked and the other is just loaded with bearing particles. If your willing to separate, I need the passenger side. If you don't want to separate let me know your price, I wouldn't need any lines.

Hey Alex,

I'm probably going to sell them as a complete set with the lines.

I just spoke to a woman at the facility, and the coolers were in good shape with no abnormal problems, and they're in the middle of refurbishing them right now . Price was $125 per cooler, that is for the complete service, to include the thermal coating.

 

I received the coolers the other day and they look great, almost like new. 95% of the fins look like they were never bent . Customer service was also very friendly to deal with

 

good to know

 

I sent mine (2) down to Texas last week, they told me a turn around time of 7-14 days once they have them, it all depeds on what they have to replace,order repair, etc. I expect them back by the middle of April. I sent them from Canada, 9 days to get there. It will all be worth it at the end. For the guys who have got their's back and thermal coated, are you still getting adequate cooling? Thanks guys and I'll let you know how I made out.

 

Bump for this thread. I might end up going this route if I decide not to upgrade my stock setup for the time being.

 

I just got mine back this week and they were not exactly what I expected to get back. Some off the fins were broken off and were flush anymore like the other ones. They were also not painted black but have an alodine coating on them they said, like a yellowish coating. They told me that they don't coat there cooler's in any sort of black paint. I am going to investigate further. I'll keep you informed. They also charged me $150 each plus shipping.

 

That's really weird. I was charged 125 each plus shipping, and as you can see in the pic, mine were definitely black:

 

any update on this? with all the great service ive heard they must have just gotten something confused.

- also....i have a 93 r2, if i want to upgrade to the dual coolers 1. do i need the r1 drivers side cooler as well? 2. Or can i just get pass side + lines?
I assume i need both collers and lines to upgrade...correct.

thanks
Drew

 

I haven't done anything yet. I don't know if it's worth the hastle because my car would be laid up for another month. I will probably call them today/tomorrow and see what I can find out.

 

93 R2 doesnt exist. R2 is basically the 94-95 version of the 93 R1, with a few 'milder' performance mods, like softer suspension, relatively speaking. If your 1993 only has one oil cooler, you either have a touring or a base.

 

Great thread. Does anyone make an oil cooler screen f or the FD? Racing Beat makes them for the RX8

if you dont already have dual oil coolers you dont have an r1/r2 model.
