For anyone installing the Nissan Motor Sports cooler in cold climates I suggest purchasing a Mocal thermostatic sandwich plate (around $100).

I was waiting for the Stillen upgrade, but I think I am about to pull the trigger on the Nissan Motor Sports cooler with a Mocal sandwich plate.

What does the sandwich plate do?

It has something similar to a thermostat in your cooling system. It prevents from over cooling your oil.

Although this post has been about lowering your oil temps with the coolers, it is important to remember that you have to also have to heat your oil and maintain a desirable engine oil temp.

The Mocal unit, as well as other similar products, fluctuates the amount of oil passing through the cooler in order to regulate oil temps. The exact same way a thermostat regulates coolant through a radiator.

In the current configurations, both the Stillen and Nissan Motorsports kits will pump oil through the coolers 100% of the time. This is great during warmer months, spirited driving and track applications. But for those of you in the northern climates where you experience freezing temps, you would have to block the cooler to allow oil temps to come to operating temperature.

My only complaint with the Sandwich adapters with the thermostatic switch is that they will have to be replaced eventually like a thermostat in a car. I have not had any experience with the Mocal unit, but I know similar products from companies like Earls and the like are pretty expensive.

The Mocal unit is available from Bat. Inc. for $95.

Should I get two since I'm in Phoenix and temps here avg 110* in summer and 70* in Winter?

Two coolers? Or two sandwich adapters?

I would say no to both questions. 1 Cooler is sufficient and the whole purpose of the thermostat in the Mocal units is to simply aid in controlling oil temps until they reach operating temperature. Once at operating temp, units like Mocal piece are cooling oil in the exact same manner as ones without the thermostat.

The only real benefit of the Sandwich adapters with the thermostat is the fact that oil temps can be maintained at a desired temperature. For you type of climate, I would not think it would be necessary.

And btw...those core sizes I promised!

Stillen = 19 row 13" x 1 1/4" x 5 3/4" = 74.62 sq inches of surface area

Nissan Motorsports = 34 row 13" x 1 1/4" x 10 1/4" =133.25 sq inches of surface area

The height of the cooler is the only size differance. But the fact that it is taller. If you do the math, there is 44% increase in surface area between the Stillen and Nissan Motorsports kits and over twice the number of rows.

Stillen (apperently) has a bigger cooler coming out but it seems to be held up at this point in time. Too bad as I'm going to pull the trigger soon on some sort of oil cooler....

Latest issue of Road & track has an update on their long term 370Z touring/Sport. When they went in for first LOF, "revealed a small leak in one of the hose fittings of our port-installed Nismo oil-cooler(repaired)....Nissan also recommends its Ester oil blend ($12 per quart) to mitigate the inherent noisiness of the 370Z's V-6".
1. Any idea who's oil cooler this is? NISMO or NISSAn Motorsports?
2. I was advised at my dealer to use the Ester oil because of something to do when starting up the car. Anyone really know why? Thanks.

Outperformance Shop has this for sale" NISMO 21300-SS370 2009+ Nissan 370z Engine Oil Cooler $780.00". No picture. Is this the Nissan Motorsports oil cooler?

Appreciate the comparison.

Anyone know how these compare to the GT Motorsports cooler. Is this the same size as Stillen or Nismo, or in-between ???

$795 is high considering I bought dual mocal 25row oil cooler kit with all necessary hardware and -10 lines for my RX7 for $1000.

yeah i think 795 is abit too much.

any idea how much extra oil capacity the nismo will hold ?
