hi all, my oil temps a bit high on my fd.. the oil coolers stock and still in quiet good condition.. so I think its because my new body kit is restricting some air to the oil cooler.. I want to customize my own cooling duct.. from carbon fiber any suggestions on how big and how much I need to cover the oil cooler?? I mean ducting the whole oil cooler or only the middle parts?? anyway would the ducting help??

 

What oil temps are you seeing?

 

you should have stuck with the c-west

 

If you have a single oil cooler, you might want to consider upgrading to dual oil coolers. The single oil cooler isn't enough for track use.

yeah I have a single oil cooler.. and I wanted to install dual oil coolers for a while now.. which brand fo u guys suggest I should buy (what size)?? and would the ducts actually help??

 

R1 and R2 models both had dual oil coolers. Your best (cheapest) bet would be to upgrade to that.

 

yeah i could upgrade to the r1 r2 dual oil coolers but.. might as well get the good stuff.. right?? so which ones should i get?? any tuning company brands?? reason I;m asking is never saw any oil coolers for sale in tuning company websites

 

well the problem is the oil cooler kits that are "the good stuff", cost over $1000. r1/r2 oil coolers will run you much much less

 

or you could upgrade to the oil coolers FDnewbie is promoting

 

Mainly, most people either buy a kit from a store (RX7Store, Gotham Racing, FDNewbie all have oil cooler kits) or just make their own. There's not a large demand for them since the only real challenge is mounting brackets so I doubt "tuners" care to invest the time for something that won't have a huge return.

First, what temps are you seeing? You need to have a benchmark to know if your upgrade helped or hurt.

Second, ducting the oil cooler is a huge benefit. Just like the radiator, air will take the path of least resistance. If there isn't something forcing the air to go through the oil cooler, most of it will go around it.

Lastly, there are positive and negatives to some kits. If you are just using your car for street driving, simply going with the OEM Mazda dual cooler setup will be the easiest to implement.

 

The stock dual coolers are good enough for the street and some track duty. You probably won't need anything larger unless you track the car in some serious heat.

Check Howard Coleman's thread: "Dual Oil Coolers Cheap". He details all the parts you need to add on another factory oil cooler. Cheap and effective.

point taken.. okay so I'm going with the r1/r2 oil coolers.. and thank you all for ur help..

 

I would personally start by looking into fabricating some kind of ducting from sheet aluminium like this car. It is important to start with some kinda poster board paper material for the mock-up and then cut the aluminium.

 

I have done the dual oil cooler converson myselft and I'm no technician, I have a complete list of parts used if your interested. I plan on doing the duct work like the above car once I'm done with the 4" exhaust system.

 

thanks jerome, I think I will try the mock up with some card board annd see how it goes.. I'll contact u back thanks again

 

the stock oil coolers have ducts. Another benefit from going with upgraded oil coolers is, it will take some of the stress off the coolant system.

I'm reponding to a pm for more photos of the oil system.








Please not how they clear the RE lights.

 

I just bought r1 oil coolers my self. I think its going to be the most cost effective way to get the dual cooler system.

 

right now I'm trying to duct my oil coolers and radiator cus the heat problem is effecting me.. anyway ordered the r1 oil coolers already hope it'll be worth it.. can anyone send me the normal oil temp, exhaust temp, and wter temp for a 3rd gen for me.. thaks

 

If using used OEM dual oil coolers, I would recommend sending out for cleaning, fin repair and thermal coating. There is a helicopter cooler repair place in Forth Worth Tx. that does a fantastic job at a very reasonable price and with a quick turn around. My coolers came back looking brand new. I forget the company name and I have misplaced my FD maintainance/upgrade receipts file (going back to original purchase in ’95) in a house move but a search on this site with my name and oil cooler should pull it up.

As to ducting on a stock front end, I would recommend the OEM ducting, I added weatherstriping foam around part mate with cooler and added SS screen (painted black) in ducting .. pull front end and fit screen forming “cups” to wrap over lip of opening then used small SS bolts (painted black) to hold in place.

Guys, the poster is in Thailand so I don't think shipping oil coolers to Texas would be a good idea. Unless the oil coolers are used and have 100k miles on them, they will most likely be fine "as is".

 

thanks a lot Julian and Darkside.. even though Mahjiks right about me sending my oil cooler to Texas, you guys are a lot of help.. thank you for the ducting suggestions.. will try it when my dual r1 oil coolers arrive..
