Dual oil cooler project - parts list and pics
I decided to make my own oil cooler kit. After some tinkering, I ended up with a dual setup using a 25 row cooler on the passenger side and keeping the stock cooler on the driver side. Overall, I'm happy with how it turned out, and I didn't break the bank. After some hard driving tonight, I saw lower and more consistent water temps, which was my goal. The car has BNRs, AC, cat, smic, etc. and runs close to 400 whp - i.e. it can get hot.
Parts list (cost was $403): Banzai oil cooler bracket 25 row oil cooler Mishimoto Thermostat (+160 deg internal thermostat, you have to buy this separately) 15' 10 AN nylon braided hose M22 X 1.5 to 10 AN adapter fitting (4x) Straight 10 AN hose end fitting (3x) 180 deg 10 AN hose end fitting (2x) 90 deg 10 AN hose end fitting (2x) 120 deg 10 AN hose end fitting (1x) 45 deg 10 AN hose end fitting (2x) Note that I had to remove two 3" sections of under tray sidewalls to accommodate the thermostat location. One in the side of the main under tray and the other in the side of the smaller oil cooler under tray piece. Both were minor and didn't affect the performance or dexterity of the under trays. Overall, everything fits well and is secure.

... also, if you're curious, the lines fit perfectly between the under tray and bumper.

Nice! I was wondering how the lines would run from one side to the other. The Sakebomb kit runs the lines through the front bumper rebar.
Do you have any ducting to the oil cooler? Dale |

Do you have any ducting to the oil cooler? Dale I don't have any ducting, but there's only about 1/4" between the bumper and the cooler. |
Is the second thermostat necessary? I don't have a clear understanding for how the OEM duals work, but I got the impression that only the first one in the circuit needs a thermostat/bypass.
|
I'm curious what your estimated water temp reduction is? With a single stock cooler, I would normally see oil temps about 20 degrees higher than water temps.

OP,
Can you show us a pic of the lines running from your engine block to the cooler. Having serious issues with my skb kit. Thanks. |

^ also keep in mind that this routing works because the stock DS cooler has an internal thermostat. For two aftermarket coolers, you'd need to route the TS differently.

Appreciated. Thanks again.

I don’t remember :), but from the pics it looks like I used the M22 X 1.5 to 10 AN adapter fittings. Here’s a couple more pics. The list above is the full list I used, so once your in there, it will make sense.
