Adding an oil cooler is really easy. The only difference between a Nismo and a non Nismo is the front damper. As posted above, you just have to do the, Nismo Flip" and install like regular.
The BP kit came with a 30 row so that is what I installed. If it didn't I would of bought the bigger 34 row Z1 kit with thermo plate.
A quick break down of the process:
1- have oil change material + 1 extra qt of oil (6qt)
2-get car in air and drain oil
3- remove front of car (bunch of screws on the bottom, 1 on each side in the tire wells.
4-attach mounting bracket to oil cooler itself
5-place 2 clips on bottom of pre-molded plastic of car. you can see the plastic in the picture below
5-Attach oil cooler w/mounting bracket to newly placed mounting clips. Note where the screw on the mounting plate are in reference to where to place the 2 clips
6-in the place where you would normally screw in the new oil filter, you will screw in the thermo plate. Apply a little oil onto the rubber seal to get a better seal. Give the bolt a nice snug once installed. My bolt was a 1'' standard socket believe. Then you will screw the new oil filter to the thermo plate (again, put a little oil onto the rubber seal to seat it better, also fill the filter with as much oil as you can prior to installing it).
7-attach the 2 new oil lines to the thermo plate and run them to the oil cooler.
8-fill oil cooler with oil prior to attaching the 2 new lines (around 1 qt)
9-fill engine with oil (5 qt)
10- make sure everything is snug and tight prior to starting car. Let it run a little, shut off then sit for 15 minutes to let the oil settle and then check oil level. Add more oil as needed.
11- check thermo plate for leaks. If the thermo plate leaks, you will have to drain the oil and tighter the bolt holding the thermo plate tighter.
