Stillen, GTM and Nissan are all using Setrab cores, the main difference is the lines, fittings and adapter plate. You definitely want the best quality lines and fittings you can find, too many failures from badly assembled lines.

^Very true, one reason why I decided on the Stillen cooler is that I could not find any reports of lines or fittings failing which swayed me.

If you are looking for another suitable option for an oil cooler for your 370z aside from the 3 kits listed. Take a few minutes to look over our kit.

We have worked extensively with our manufacturers and customers to create...what I believe...is the most comprehensive oil cooler kits for the 370z.

Z1 Motorsports 370z Oil Cooler Kit

We have attempted to address ALL of the issues we have found with our competitors oil cooler kits and to create a installation manual that is easy to understand and follow thru the entire installation process.

Dustin,

Do you supply -10AN lines or -8? Your web page indicates both sizes, -8AN fittings with -10AN lines.

YEEEEEEEEEEEAAAAHHH....that's definitly my mistake.

The lines and fittings are all -10 AN on the 370z oil cooler kits.

We use a -8 AN on our 300zx kits and I guess I mixed something up in my head when I was creating the pages for both kits.

Sorry about the confusion!

I really like the oil kits that Z1 has to offer...I'll be pulling the trigger on this real soon...The fact that you retain the OEM factory oil filter and the bigger -10 lines are a plus.

Ok guys just got my Nissan oil cooler installed by Raceway Nissan. Well I drove my car from the dealership to Beaumont and drove back to Moreno Valley through San Timoteo Canyon. I drove pretty hard, and the gauge did not move from 180 degrees. When I got back to the MV, I did a lot of stop and go because of the stop lights, it sat at 160 degrees. Is that a normal range? Now every time I push the throttle there is a whistling sound, sounds like air, is that normal as well?

One more thing, in the back of the installation guide it says
Note: This oil cooler is not thermostatically controlled and should be removed or bypass in cold temperatures.
Is this good or bad?

Josh@STILLEN · 11-18-2010, 08:06 PM

160 really is too cold. You can either try fabricating a shield in front of the cooler which has worked for some, but realistically getting a thermostatic sandwich plate and swapping it out will be the best method.

It bypasses the cooler until the temperature of the oil comes up. Too large of a cooler can overcool the oil as well, and the Nissan cooler is large. Oil that isnt up to temperature is also bad, and should be remedied.

Wow, that’s not too shabby, hey where can I buy this thermostatic sandwich plate?
I will swap it on my next oil change. Thanks for the feedback Josh.

Not to dispute what you posted Josh, but here is what Dustin@Z1 had to say about it when I asked him about the 160-ish temperatures I was seeing:

Quote:

No worries. This is perfectly normal. There is a slight flaw in the VQ37VHR's design that we have discovered. Like I have mentioned in the past, over cooling the engine oil is just as detrimental as over heating it. The general oil temp range you want to see on a properly installed oil temp gauge is between 190 ~ 210 ideally.

This engine oil temp is what you want to see COMING OUT from the motor. In the case of the 370z and any add-on oil cooler, you are actually getting a false reading. Since the factory temp gauge reads engine oil as it exits the Oil Filter, you are actually reading the oil temp coming directly from the oil cooler. The flow pattern for engine oil on a 370z is as follows:

Pick Up Tube --> Oil Pump --> Oil Filter IN --> Oil Filter Out --> Oil Cooler --> Engine Block (Temp and Pressure gauges are located in this galley)

The temp you are reading is actually what is going back INTO the engine (which is perfect). By the time it cycles thru the engine, you can expect to see engine temps in 200 degree range.

As for the thermostatic sandwich plate, it will bypass roughly 80% of the oil back into the engine when too cold. It will still flow ~ 20% thru the oil cooler (preventing air pockets from forming).

To get a TRUE Oil Temp reading, you would need to install an inline oil temp gauge coming out from the Thermostatic Sandwich plate before the oil cooler.

WOw, thats some good inofrmation. Thanks. Reading these post does help not only me but anyone with these issues. Thansk for the support.

Great info.

We're still pushing moderate temperatures out here in Southern California, and I don't discredit what Z1 is saying in regards to oil temps, but it's such cheap insurance to swap to a thermostatic plate. Moreno Valley can have some cold times, especially in the upcoming months.

The thermo plates begin opening at 160 degrees and are fully open at 180.. it just helps to bypass enough to get the engine temps up and into the optimum range.

All of the cold temp issues are more of a precautionary tale to those who want to completely abuse the vehicle with hard driving when the engine isn't up to temp, and oil needs to be performing at it's best, which it doesn't do at those low temperatures.

Will you have a problem, potentially not.. but as it dips into as freezing of temperatures as we get out here in SoCal, I'd be much happier with a thermostatic plate which will cost you a small fraction of the price youv'e paid for the oil cooler.. but perhaps I'm overly cautious, but definitely would want to make concessions for the cold, especially for those who live in "real" weather areas..

Agree with this and with what Dustin stated. Dustin told me of the way it reads oil too when i asked him. Of course though, I would, as did he and the guys at z1 also, recommend a thermostatic plate to everyone. period.

Well, even with your cooler and the thermostatic plate, it still sits around 160 cruising at night time temperatures. I find that the only time my oil temps ever go above 180 is either sitting in traffic or really pushing the car hard.
