I track my FRS and I really needed an oil cooler after seeing the oil temp hitting 285*F in 90 plus degree heat. After some research, I was able to piece one together for under $475 after sales tax and shipping (versus $650 + sales tax + shipping for Perrin or Mishimoto). I got everything at
http://www.racerpartswholesale.com/, and wanting to outdo Perrin (13 rows), I went with a 16 rows and ss lines instead of rubber hoses.
I didn't plan on writing a DIY so I didn't take as many pictures as I should. I basically mimicked Perrin's set up, so you can find a great deal of the install here

I did have to do go through some trial and error, so I'll mention them here.

* Oil cooler mount - Perrin has some nice mounts provided for you, but there is no real need for one. I used two 65mm bolts/hex nut with 4 fender washers to secure the oil cooler. Why 4 washers? I used 2 on each side - 1 for the underside of the car, and another to place under the oil cooler. Basically covering the plastic rivet hole from top and bottom.

* Lines and fittings - You'll need total of 8-foot long ss braided lines, two 90-degree AN fittings and two 45-degree AN fittings. I made a mistake and got two regular fittings instead of 45-degree ones.
As you can see, the straight fittings made it impossible to gain access to the oil fill cap. It's pressed against the air box. I think you should be able to get away with normal fittings if you have CAI or a different air box. I was able to find one 45 degree fitting locally and made it work.
Unfortunately, it's still pressed against the airbox, but at least we now have clear access to the oil fill cap. Even with all that space between it, the oil fill cap will just barely clear.
As for the length of each line, I had the 8' cut into two 4' lines. I think it might've work better if I had one line slightly longer (maybe 3 inches longer) than the other, since 1 line has to go across the oil cooler. As you can see in the picture, 1 of the lines certainly has a lot more slack.

After everything's mounted and installed, I did noticed that the fittings above the oil cooler is pretty much hitting the underside of the bumper beam. There's still a good millimeter or two between the fitting and the bumper beam. So 16 rows is basically as big as you can go without finding another mounting location.

Since the car's already jacked up, I figured I'll change the oil out and "install" my new Greddy part
It's your normal 6 qt + 1 more for the oil cooler. I track a lot so I run 0w30 just to be on the safe side.

This will be put to test on Monday at Laguna Seca. Wish me luck
This is my first DIY. Hope you found this helpful
