Has anybody ever used the Greddy kit? I wonder how it fits? It seams like a cheaper alternative for those who with a touring or pep model that just want a nice passenger side oil cooler.

It will take aftermarket hoses and fittings, and special adapters to go between the AN fittings and your metric fittings/BPT threads. If you're going to go that route, you should just buy stock parts that will work and can be routed easily. Just my 2 cents.

I'm considering getting dual oil coolers but only track my car 3-4 times a year. I've never had a water temp problem, but have no way of knowing the oil temps in the car. For infrequent track use would the r1 dual coolers be good enough? I'm trying to buy a pfc and don't want to spring for $1000+ oil coolers at the same time.

As I said above, I think the stock dual oil coolers are adequate for all uses except for regularly tracking the car in hot weather.

I agree with rynberg ^

I've been tracking my Touring on and off for a few years and finally got around to installing dual R1 coolers about a year back. My water temps never got past 90 degrees Celsius, but to be fair it was in fairly cool weather (~70 F). I believe the stock dual R1s are good enough for most application, including yours jayk.

The stock dual coolers are fine for a stock or mildly modified FD for any driving condition including the track.

I have a touring model and paid about $300 for a passenger side oil cooler and lines from a wrecked japanese RX7. They're not that hard to find used. But yes, new they cost too much so you might as well go aftermarket if you want new.

what about a single 25 row (yes, like Chuck's kit), would that be equivalent to the R1 duals?

Rynberg, Mahjik and others that may apply,

Do you guys happen to know what fitting would be used if someone were to build their own kit?

The reason I ask is this. I have a few oil leaks on the FD (base model) with one being old oil cooler lines. I bought a new aluminum oil cooler and would like to mount it in the stock location. These are the fittings that I am using with the new cooler http://www.raceplumbing.com/product_...roducts_id=242. These should be fairly easy to hook up.

Now for my real question. Is there an after market fitting that would attach to the stock lines in the picture
or would it be better to run lines all the way to the engine and have the fittings mounted directly to the block?

^ There are no fittings that will attach to those except stock. You have to remove those hoses as well and attach directly to the front cover and oil filter stand using adaptors if you're going to build something.

First of all, do not use those fittings. You will need to use swivel fittings. Your install and maintenance on the car will be complete hell if you don't swivel fittings.

Secondly, AFAIK, no one mass produces a fitting that converts AN to metric with the FD threading. Chuck (RE) has custom fittings made so you can use the stock hose ends in the picture. This is the best solution IMO. Maybe if you email Chuck and beg, he'll sell you a set.

As I said above, Chuck has these fittings custom made. They are very nice CNC-machined pieces. I doubt Chuck would sell them separately from his kit but you never know.

Trav,

also remember that the oil thermostat is built into the drivers side oil cooler. When you go aftermarket, you need to add a thermostat.

That was one thing I did know. I am a little weary that I may just end up having to buy a kit and go from there. I am afraid that if I try to do it, I will just srew it up.

I don't think are larger single oil cooler would cool better than the dual system because of the airflow limitations of the small inlet duct. Two small inlet ducts doing to two small oil coolers would cool better than one small inlet duct going to a double size cooler. At least I think so in my non expert opinion.

It should just depend on the setup you are using. Things to take into consideration...

Size of oil cooler (overall size of the actual fins and how much they are exposed)
Size of oil cooler (number of rows)
Oil cooler material (I believe aluminum has better heat dissapation qualities)
Bumper shape (my new oil cooler fits perfectly behind one of the openings)

I have dual 34 row coolers from RE. I bypassed one for awhile and my highway oil temps in 103+F ambient went up from 155-160F to the 190's.

I think Chuck at rotary extreme was the only one to solve this problem with custom made fittings.

7racer,

Which connecting point is this?? I'm about to buy a used CWR cooler and wanted to know what I should look for.

I had it at the from the engine block to the thermostat. I know maxcooper was able to fit his better. Mine was used also and the lines alittle short. I just assumed that was the way it should sit. I think the tension on the system weaken the fitting from the braided line to the fitting therefore causing the oil leak and loss.

Here was my idea for solving the issue of stress on the motor-to-tstat elbow hard connection. Besically just a new elbow and some braided hose, that will allow enough slack for engine movement.

I haven't actually implemented it yet.

I bought a set from Chuck, no need to beg

I plan to use them to install my CWR kit using the stock feed and return lines and this way I'm not using the hard CWR connection at the front cover. Winter project for me!
