Does anyone know of a company in Austin that would install the Nissan Motorsports unit for me. I am not a DIY person unfortunately and it appears my dealer has never done one and I would hate to be the first for them if I can help it. Any help would be appreciated.

No Modshack dont do it!!!!!!

:facepalm:

Just curious, why would one Z have a higher operating temp than another Z, assuming they're both driven the same way? Seems if one over heated, they all would.

Not all engines are created equally unfortunately.

Wow! Surprised to hear that.

This is quite an engine we have in our Z's, state of the art. To have them not all created equally would mean shoddy workmanship or poor quality control at the factory, and I have a very hard time believing that Nissan is doing that with these engines, or with anything to do with the whole 370Z for that matter. These are very solid, well built and quality automobiles all the way around, as their history will prove them to be.

But ........ anything's possible, I guess.

I'm not trying to say that they have shoddy workmanship or poor quality. But it's just a fact that not every engine is exactly the same. It's not like EVERY engine has the same HP numbers to the wheels, or that the valves on each car seat exactly the same. There are so many variables that come into play that make each engine different.

Right. It's like . . pants. You can go buy two pair of pants that are exactly the same. Same brand, same size, etc. But try each pair on and there will most likely be minor variations between the two.

I find it out that over 40% report no issues at all with oil temperatures, but only 2% say that no action is required. If you're not having any issues, like me, why do you think there needs to be a fix?

I'm certainly not disputing that some 370z owners are having issues, of course.

I've never driven a sports car before, but what *should* be the oil temp on a 100 degree day during spirited driving? Are there any sports cars without factory oil coolers running cooler than 220 in that environment?

I'm sure I'll be flamed for it, but I think a couple credible forum members having some rough days after tracking (or possibly driving the snot out of) their Zs are making people go into panic mode. I guess after a Georgia July passes, I'll find out if I need to eat my own words.

Well, I plugged "What is the ideal engine oil temperature?" into Google, and the first hit that came back has this in it:

"The ideal operating range for engine oil is 180°F through 200°F. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 200°F and 220°F with oil temperature ranges between 20°F and 75°F HOTTER. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 220°F rapidly loses its ability to lubricate and cool causing accelerated fatigue and premature component failure."

What an Oil Cooler Does

Now, it looks like this page is on the site of a company that sells oil coolers, so I don't know how reliable the information is. I wouldn't stress out over temps going over 220°F if you're using a quality synthetic, for instance. But my point is that you can always Google the question if really want to know. And maybe a search at bobistheoilguy would yield some good answers as well.

You overanalzyed my question just a bit.

Many are claiming dangerously high (or at least problematic) oil temperatures under certain conditions. My question isn't what an ideal oil temperature is, because I feel under normal conditions (both driving and environmental conditions), most will find their Z operating well within the limits of "normal oil temperatures".

My question is what do you expect our oil temperatures to be at, with the understanding there is no factory oil cooler, assuming you're tracking or sporty driving on a hot day?

If the expectations of the 370z owners are that the car should be running at a perfect 190-200 degrees on a hot, track day without an oil cooler, I think the problem may be our expectations, not the engine.

Thats the Million dollar question, What temp do we start to get worried about? Im seeing 220 right now in 65 degree weather with basically normal driving, for me any way. So when its 100 degrees outside what temps will I see? Im thinking 240+ and is that bad? I dont kow but I will put a small oil cooler on for peice of mind.

You should be running 245 under spirited driving. Tracking you will need an oil cooler.

Hey my expectations are OK, it the worlds thats F'd up. LOL
