Introducing the Z1 Motorsports 370Z Oil Cooler Kit *Customizable*

Dustin@Z1

The ideal oil temperature really depends on the oil itself. Such things as:

• Oil Weight
• Type (Synthetic, Blended, Conventional)
• Manufacturer of the Oil (???)
• The Engine/Car itself

The 160 ~ 180 range is a safe minimum in my opinion. The oil cooler will drop the temps quite significantly when moving at highway speeds. But the extent of the temperature drop will depend on the speeds you are traveling, outside air temp, load on the engine, etc.

Keep in mind. When installing ANY oil cooler, the temperature you will be reading on the factory oil temp gauge will be after the oil has cycled thru the oil cooler. With this said, that means the temp you will be reading will be at its coolest as it re-enters the engine. The actual temperature of the oil leaving the block (which is what you are primarily concerned with) will be higher. The oil temperature on the gauge will ONLY match the temperature leaving the block when the car is not moving. As air passes across the core, it will cool the oil. You will see the oil temperature drop as you are driving.

On my personal 1992 Nissan 300zx Non-Turbo that I have been building over the past few years, I have noticed a 3 ~ 5 rwhp gains just getting the oil temps into the proper operating range (around 200 ~ 210 for my car). My engine is a version of our Stage 2 short block with Stage 3 heads. The tolerance around the main and rod bearings have been altered from the OEM specs.
