Aftermarket Oil Cooler recommendations
What are some good brands for a shiny new oil cooler? (Literally, I want it to be shiny) ha.
Also My Rx8, 2004 AT only has one oil cooler and its on the driver side. I know the newer model rx8's have one on each side. Anyone know if its possible to mount two, functionally, on my model? Thanks a lot! |
Search man, there are a few threads on this subject already.

Just went rummaging and found this gem ;) Thanks
"Quick and dirty :) http://www.flickr.com/photos/9krpmrx8/5593400424/" so what oil coolers would you recommend? and how do I run dual if I have single now? I'm not too sure how that stuff works. Please dont tell me to search again though, just explain. please. ha |
Have also Been thinking of doing this. here is a little help

:lol: That diagram is awesome.
The fittings need at the coolers (factory anyway) and the engine are M18 x 1.5. If you run custom lines (local hydraulic hose shop) you can easily add a secondary cooler. |
Setrab is one of the best...they are pricey but very efficient compared to most others
|
Good enough for Aston Martin and Ferrari :) I will redoing my setup again soon.
|
I think with the 2 coolers, thermostat and the fittings and hose I was close to $1500...not a cheap undertaking ...

Not cheap at all unless you find decent used coolers. Long brand coolers are decent too, sometimes you can get them fairly cheap. |

I was looking at buying just like a pair of $150 (each) oil coolers off ebay. Something like this: Universal 19 Rows Oil Cooler Kit Engine Transmission Oil+Oil Relocation Kit Row | eBay call me cheap but I'm just wondering if theres anything wrong with that? |
Brettus only runs one cooler and has not had an issue even turbocharged, he is using a stock passenger side oil cooler as a secondary radiator though IIRC. I think it depends on what you are doing with your car.
Right now oil temps are not an issue for me and my custom setup is working fine, even in this 100F+ weather. I am just redoing mine to clean things up a bit. |
The stock oil coolers are decent and fine for most, Dannobre's car is on another level and track driven.
A kit like the one you linked fed from an oil filter adapter plate would work and would be an easy way to add a second cooler but with fittings and lines you don't wanna really cheap out, if you have a failure it could cost you big time. |

I live and die by Setrab's coolers and earl's fittings.

Fittings are the connection points that the hoses attach too and what screws into the block and coolers, AN fittings, JIC fittings, etc. Cheap aluminum fittings can break or leak pretty easily.

I think all of the time spent on a upgrade is a waste of money. I ran a Fun Day in 98-104 degree day in 20 minute runs never really running under 6k rpm and bouncing 9k rpm all around the track and my oil temperature never went over 200 degrees and dropped after to 160 degrees and stayed during my cool down lap. Daily driving I stay around 180 degrees in busy traffic.

Start looking for a part out Rx8 or in my case started asking around and
found a complete set (both coolers and hoses) from a guy that was upgrading like 9k did. Paid $300 for everything and sold the extra drivers side for $75. Total cost $225. |

I also want a nicer looking oil cooler because theyre very visible with the mint blue front end...
If I buy a second passenger OEM cooler, I wonder if I can get them both powdercoated or something... |
Pathetic. Click this

It's not something to do on a whim, it needs to be carefully thought out. |

The factory coolers are very good, the only downside is in cold weather. They have crappy thermostats and allow cold oil to flow and so it takes a while for the oil to heat up (not good). A good oil thermostat is going to allow the oil to heat up quickly by sending it back to the engine and going to a simpler hose routing with larger lines increases oil pressure (proven by me). The factory lines and fittings are know to rust and leak in winter climates and replacement parts are very expensive unless you find a part out going on at the time you need a replacement. Custom lines and fittings are generally cheaper unless you go with top notch stuff.

Good advice 9K. peeps --dont overcool the oil either. Most track driven RX8 will hardly put a load on the engine until the oil temps get to 160F+. If you use synthetic oil it is good to go to 250F+ as far as lubrication is concerned.

super thread revive time!
Would you recommend Mishimoto oil coolers? I've seen them on various built stance:nation cars so I assume they can't be horrible. also how many rows would you suggest if I'm doing dual oil coolers? |
thread revival........
I would like to take this discussion a step further. My reason---serious engine builders including racing beat mazmart , pettit--etc will tell you to not let the oil temperature get above 200-205 F. THIS IS MEASURED ON THE COOL SIDE__returning from the coolers. Unless you live in a cool climate-- i will venture to say that the oil temps are above that routinely. Especially in the south. ALL the members of the Ga RX8 club see temps higher than that--on track and during city driving. Some see 200F even just driving on interstate during the summer time. Now oil viscosity does influence oil temps. Most of us do use a 40 wgt oil--synthetics and mineral. My point is --i think we need better oil cooling and what have others done? before the summer ( in Ga) I plan to upgrade my oil cooling system ( currently stock with the vents cut and one cooling fan for stop and go traffic) . My system is borderline--the thermostats work fairly well as I see now ( winter months) a return temp of about 180F. But in the summer i can see 200-205 fairly often. On track I do see 220F often. My coolant temps are well under control but the oil needs a little help? Is this something that needs addressing or is this another olddragger ramble? |
Well we will see this summer at full boost but for now I struggle to get temps well above 200F and that is with oil flowing thru the turbine housing.
Honestly man when I was measuring temps in the oil pan there was not a huge difference in temps versus measuring it at the oil filter plate. Hoss-05 is plumbing in a cooler with a fan on the oil line that feeds his turbo. I am curious how much that will extend the life of his turbo along with his use of Evans coolant. |
