Who sells the a single oil cooler that can handle a tuned 13b? Just the core for a reaonable price.

Also I was wondering what problems I would have if I were to take an intercooler and welded fittings on it...

 

B&M oil cooler get it from Jegs , or Summit ... they cost around $70.00

 

Lots of companies make oil coolers. Here are some available at Baker Precision: http://www.bakerprecision.com/setrab.htm

Believe Pete T (RXTech List) fit two stock coolers in series on his ITS 7.

wait wait wait, i'm confused as to why the oil cooler prices so cheap. a 44 row is 300. why then maxcooper did you get the cwc dual oil cooler or why would anyone purchase the rotaryextreme 34 row oil cooler at 850 dollars?

roatryextreme i you are reading this can you tell us what the differences are? and even if you have to fab something, would it cost you 550 dollars to do so?

That is the Prices for the cooler only. The rest of the cost comes from the stainless steel braided lines, the fittings and oil thermostat. That stuff really adds up fast. Plus you are looking at a kit that is prebuilt and ready to bolt on. most come with air ducts as well.

I'll have all the parts for a 34-row single sided setup by mid-next week. All told, parts are running about $550. I have to make my own brackets and cut the lines/fit the hose ends, etc...Building the stuff is half of the fun so it's definitely worth the cost savings to me. It's something I can do at home with no worries. I purchased a Setrab from Baker Precision and IMHO, they're exceptional oil coolers. They're OEM gear on Ferrari's including the GT and Challenge 360's. Good enough for me! :-) For lines, there are several choices including Earl's, Aeroquip, and Russell. Same for fittings. If I did it all over again, I'd use the Aeroquip Starlite series which has a nomex braid/sheath making it fire resistant. Lighter than conventional stainless braid too! In the end, it's the fittings that really jack up the costs. 10AN 90 degree swivels run about $20 a pop. 20ft. of braided costs just over $100 in 10AN size as well.

i was reading the thread over and over and i do believe that rotaryextremes kit is probably worth it. alot of rx7 owners do like to work with thier hands (but a majority wants the car up and runing fast) and this kit saves some extra time on bigger projects. and looking over some of the cost of fittings, adapters, brackets i didn't realize hw close it did come out to the 550 price.

luigi

jesse my recommendation is rotaryextremes.com and his 34 row oil cooler, if you have to go bigger there is a 44? row available through bakerprecision.com , but i don't see why.

 

Yeah, as others have posted, the coolers are not the bulk of the price. The CWC kit comes with nice (functional, good fit) CF ducts, too, which all together made the kit seem like a good deal to me. I added up all the prices for the individual components and it wasn't that much cheaper than what I paid for the kit. Ducts and brackets, pre-cut hoses, no lost money from buying stuff I didn't need, etc. was worth the difference to me.

An unducted or poorly ducted oil cooler will work very poorly compared to one properly ducted... ALWAYS duct it well! Don't let any air from the opening on the nose get around that cooler.

Wade

 

I'd agree with Wade. Especially if you're using the stock nose. If you have a GTC or FEED Type II, CWest, etc...it becomes less crucial because a majority of the oil cooler is exposed to a direct shot of air. A 34 row would DWARF the stock oil cooler opening, necessitating a duct. Mazdacomp commented that oil cooler ducts were not necessary with the GTC front end and stock oil coolers.

I have an Earl's oil cooler. Works excellent. The cost was cheap too. All the info is here:

Earl's oil cooler on my RX-7

check it out!

Does Earl's own or resell Setrab coolers? I thought that they made their own. Your pix say that they are Earl's coolers, but the label says Setrab. What's the story?

 

Rick, you state: "This is Earls #42510 oil cooler. This has all Earls plumbing as well."

Do you still have the part #'s for the lines & fittings?

Thanks,
Eric.

 

Obviously the label on the cooler core says Setrab - therefore the manufacturer is not Earls. If you can, by it obviously from Setrab. I just want everyone to know, this is what I got from Earl's. I doubt you can go up to a shop called Setrab?

Rick

 

Sorry man, I wish I had all the hose and plumbing I used to tell you guys. You will have to do like I did and piece it all together. The good thing is I have pictures of the finished product to help guide you guys.

The "Mocal" seems to be a popular and nice looking unit.

 

Just trying to get clarification on your statements...

 

No problem.

Sorry... re-reading my post, I sounded "snippy" - sorry.

Rick

 

For those of you who want to do it yourself, make sure you get the thermostat. Without it, the oil cooler will burst. If you add the cost of thermostat and 4 more AN fittings that you need, you will see it does get very expensive.

For the 34 row kit, the cost is roughly following:

34 row oil cooler: $300
fittings all together: $225
SS lines: $100
thermostat: $100

The $125 difference is for my labor of putting the kit together, R&D, and making the brackets. I rather sell bodykits all day long than making the oil cooler kit. It's too labor intensive.

Chuck, do you have any in stock?

 

Nope. I don't keep the oil cooler kit in stock. It's a made to order item. Sorry Michel =(

What about the other style of oil coolers? Kind of like an air-water intercooler style. The oil cooler is basically just a pipe with a larger pipe around it. Coolant flows through the center pipe, and oil flows in the jacket surrounding it. A friend told me that these style of oil coolers are more efficient. Any comment?

If they are more efficient, it would also save a lot of room up front and save some weight too.
