GE3KSPD Motorsports put together a custom oil cooler kit for the GenPu Mazdaspeed 3 that works with a FMIC.

Check out the blog in the description of the video to see exact part numbers and how to put it together.

Thanks for letting us know this moose. Btw I keep forgetting to ask, would you be able to meet up one of these days? I wanna check out this custom cold pipe of yours since I like the one piece design.

Of course! What days and times are you free?!
 
Building my own oil cooler. Using Earl's cooler core, and thermostat, a custom plate that will delete the stock cooler and let me run my 2 systems separate, and then all the lines and shit. Doing it with a good core adds some cost, but I hope it will pay off in the end. Total will be about $500-550 when Im done and hopefully no more 300 oil temp track days.

True, but if you are looking for just an oil cooler kit for a decent price ($380) then bam! I would steer towards this if running the JBR crash bar.

Yeah, I need proper cooling for the track, and I run a OEM Crash bar. I will do it right for a bit extra. My cooling core will be a fair bit bigger than the JBR too.

that kit has no thermostat. no thanks.

Thermostats are pointless and a waste of money They open well below full operating temperature and are prone to failure. Once open they stay open so....why spend the extra money. If there was a benefit we'd offer it.

If you live in a climate that is so cold you feel you need a thermostat to allow that car to reach operating temperature, let the car warm up for a few minutes before taking off. Oil comes up to operating temperature pretty quickly.

I mean where I live its not uncommon to see -20 or more, so yeah I see a benefit there. Also, I would assume cheap thermostats are prone to failure, but like anything else a quality part should last. I dont want to be running around in winter with a oil temp of 100 degrees, just seems like the right way to do it.

It's not really a quality issue, it's duty cycles and the nature of how they work that cause the potential for failure.

Oil coolers don't really cause the cars oil temperature to run much if any cooler. When sized correctly, they prevent the oil temperatures from rising beyond the normal operating temperature when under load, like on track. Also, a larger core is not better. Larger cores increase the pressure drop. You want just what's necessary to do the job.

Larger cores are not better for cooling... unless you are looking to add more oil and/or more thermal mass... I have seen 944 intercoolers used to do both... and a larger higher quality core might outflow/restrict less than a lower quality small core.. all things equal? I agree.

I sized my core from the manufacturer per my horsepower level and based on volume. Pressure drop between the cores is a concern, but more so is the fact that my car loves to get HOT (300 degree oil temps at the track last week) But being a car that is daily driven in Michigan year round, I felt that a thermostat is a worthwhile investment to help regulate how the oil is being treated.

The set up you are selling is nice for sure, just dosen't meet the needs of what Im looking for. Also separating the oil from the stock oil cooler (no more oil and coolant heating/cooling each other) is a nice option for me to help isolate my heat issues.
 
Thanks for the share guys. Sorry, I've been slacking with keeping up with the forum.
To answer some questions/concerns:
- I've chosen this specific core with the help of some veteran racers and the guys at racerpartswholesale. I know the price might make it seem to be on the cheap side, but this company sells a hell of a lot more than the other "name brands" and not really targeting us ricers who are willing to pay more to feel better about it. They do sell "better" cores, but they informed me most of their experienced customers opt to buy this specific core.

- As for temps, I'm constantly seeing 185-200 on the road. Never over 210 after some serious beating. On the track, after three sessions in 85* weather, it peaked at 230*. But it hovered around 220-225 most of the day. I never did track days before the cooler nor did I have a temp gauge. I mostly did AutoX before this mod. I highly recommend going with a thermostat if you lived in a cold state. Go with a decent one so you don't have issues down the line and keep an eye on the oil temps to make sure they get up to 185 fairly quickly.

Don't take my word for it. I've done my research and that's what I came up with to fit my need. Keep in mind, I don't daily the car. It usually only sees hard miles. Oil gets dumped often. So with that being said, you might need to think about it more if you plan on this to your daily.
