Again.. not discounting Z1's info on the temp's.. but having the thermo plate doesn't take any interaction from you, and as noted in the info on the Nissan Motorsports cooler, that a kit without a thermostatic plate should be removed at times of extreme cold temp's, you have security knowing the plate is bypassing the cooler when not needed.

Having control of the temps to not go below minimum operating temperatures is key.. and 160 degrees is lower than you'd like, but taking into account the engine working at a touch higher, acceptable, but an oil cooler can cool the oil too much, keeping the engine cooler than intended, especially when pushing it.. which hopefully any Z owner is bound to do.. otherwise why own it, even if it's a good on-ramp to the freeway at any given point.. regardless of outside temperature

Good points, I am not worried at all being in Socal and the thermostatic plate I got from you guys with the 25r kit seems to be doing its job since the oil temp never goes below 160. I think that 160 is high enough to avoid going low enough to be out of the safe operating range with oil that is too cold, especially when using a high quality synthetic oil. I am definitely not inciting anything, you are correct!

Oh, I totally agree, I think there is little reason not to get a thermostatic plate, regardless of the temperatures. It will always help get up to a safe operating temperature quicker, no matter what the current climate is. Even after my car sitting in the heat of the Florida summer, it still took time to get up to 180 without a cooler.

I just think its important for people to know that when they get an oil cooler that the temperatures reading out aren't correct. It could also be kind of dangerous if your readout is saying something like 260 and is instead over 280, where limp mode should be kicking in (but isn't). Probably something to keep an eye on while on the track.

Agreed with people should know. One morning i was driving out at 6 am. Temp outside was 33 and my oil was reading 150...'was worried and went to dustin tomask him to wrap 75% ofmmy cooler in header wrap. Thas when he told me! Big relief tbh.

How far off is the factory oil temperature gauge? Is it reading low by roughly 20 degrees then?

from what i understand, theres no set difference. depends on the ambient air and the size of the cooler/speeds etc.

Yeah, that's my understanding as well, but 20 degrees might be a decent assumption. You can really tell in the case of "low temps", because if you have a thermostatic plate, you will see it get up to around 160-ish easily, and then usually stick around there unless you get stuck in traffic or are driving aggressively. Since it makes it up to around that temperature and sticks there, it seems like the thermostatic plate must be completely opened so it should be actually around 180 degrees. Or at least that's my logic behind it.

Maybe Dustin can chime in and give us a better idea. We really should make it a separate thread and sticky it.

Ok guys where can I buy this thermo plate? I have driven my car and it does sit at 160 degrees.

Now I have seen a couple of installs, here is the booklet Nissan gave to me. Today I took down fenders and bumper well to install fender brace, I did see the dealers install. It’s exactly how it’s in the instruction guide, now my only question is why does it whistle, especially when I push the throttle? Is that normal?
Well here is the instruction guide I received from Nissan.

Nissan Motorsports does not offer a bolt on Thermostatic Sandwich plate. They use an odd thread pitch, low profile -10 AN Port Fitting that threads directly into their sandwich plate adapter.

We offer a conversion kit for customers with the Nissan Motorsports Oil Cooler Kit to convert their lines over to standard -10 AN Fitting. In the kit we also include a Mocal Sandwich plate adapter and (2x) 1/2" NPT Port Fittings.

You will have to disassemble the two lines in your kit in order to swap out the fittings. The total conversion process only takes about an hour or so to complete.

Here is a link to the kit we offer on our website:
Nissan Motorsports Thermostatic Sandwich Plate Conversion Kit

http://www.z1motorsports.com/g37_370...600&page=popup

The kit will run you $150 plus shipping.

There are a few added benefits to the Mocal design over the Nissan Motorsports Sandwich Plate Adapter:

• Fittings on the Nissan Motorsports piece have been shown to leak over time. (Forged fittings with wrong 0-ring groove cut in some models)
• By adding the -10AN to 1/2" NPT Port Fitting. You are introducing an extra fitting. This gives you an added level of protection against damage to the sandwich plate adapter or lines if you accidentally over tighten and damage a fitting.
• The Mocal Sandwich plate is MUCH more compact in design. This allows for "clocking" of the sandwich plate where the lines are no longer facing downward, like in most kits.
• Removal of the oil cooler kit is much faster, since you are not having to remove/re-install the engine oil filter bolt.

I hope that this helps you out and gives you an option for a Thermostatic Sandwich Plate. Let me know if you have any questions.

So in my case I wont be needing the oil filter bolt, right?

So getting this would make my kit even that much better, lol. OK now the noise, why does it make noise when I push the gas? Its that Normal?

I will be ordering the kit soon, once i do my oil change I'll go ahead and swap it. Thanks for the input.

The noise is normal and not harmful. It happens on both the Nissan Motorsports, Z1, GTM and Stillen kits from my understanding.

The reason we offer the center bolt is just in case you loose, trash or are not returned the factory center bolt when installing the Nissan Motorsports Oil Cooler Kit. Unlike the spin on type sandwich plates used in the Stillen and Z1 Oil cooler kits. The Nissan Motorsports requires that you completely remove the center oil filter bolt, replacing it with the longer OEM Nissan piece.

We have heard cases where dealerships and other like shops trash or fail to return the center oil filter bolt to the customer. This is BAD since the customer will not be able to remove the oil cooler kit and return the vehicle to stock without it.


It is also very likely that the center oil filter bolt is damged when initially removed, if not removed properly.

If you still have you original oil filter bolt and it is in good shape, then no worries. You do not need to purchase an additional piece.

I felt that this may also help answers some questions for those of you in the market looking for an oil cooler kit for your 370z:

http://www.z1motorsports.com/imageGa...Comparison.jpg

I have compiled as much information as I can about all 4 oil cooler kits (2 Stillen; 1 Nissan Motorsports; and 1 Z1). If you would like to have any additional information or correct any possible inaccuracies, please let me know.

Thanks Dustin for all this great info and comparison. I will be in touch with you when the time comes to pull the trigger on 2 oil cooler units (for two cars).

How well of an install does the 25 and 34 row work with Injen's CAI?

Dustin, your information looks fairly accurate.. I'd have to see who the thermo plate mfg is to confirm, but most of the info is correct, except for a couple of things.

The instructions for the STILLEN are for mounting it on the passenger side, and that's because we've written our instructions for maximum compatibility with our other oil coolers, such as the transmission and power steering coolers. We've had plenty of customers mount this kit on the driver side. In that application, no moving of the factory PS cooler is necessary, but we do supply everything to move the PS cooler including new lines in both the Street and Race kit.

Also to note and be fair, we have the stainless steel lines custom made by Goodridge, and while more expensive, this is all Goodridge does, and build a superior line, and haven't even had a hint of a line failure.

The thermostatic plate we use does require a filter with a bit thicker rubber seal on the filter, so the Nissan branded filters will not work, but as you've read aftermarket filters such as K&N for the exact application work fine. Although we still recommend sourcing an equivalent filter to the Fram PH3950, or K&N HP-1005, which is readily available anywhere.

I think out of fairness that the Stillen cooler includes long enough lines to easily mount the cooler on the driver's side of the car and retain the factory location for the P/S cooler. Just drill a few new holes in the bracket they supply and it sits right where any driver's side mounted cooler would be with line to spare.

Guys, thanks for such great input. For any one debating to get an oil cooler, you should. I have been driving my car up and down and it feels good not to worry about the car heating up to bad.

Josh,
Thanks for the info. I will update that sheet when I get back to the shop and post a corrected table.

I was trying to be as objective evaluating the kits as possible. From my research putting our 370z kit together I checked out the Trans-dapt piece which appears to the same one in the images on the Stillen site. If this is not correct, let me know. I will correct this as well.

Christian,
Thanks for posting that up. That will definitly be helpful to people installing the Stillen kit.

Also, for people looking for the filters for the Stillen Kit. This may help with choosing a comparible oil filter. K&N Filters list all applications that use each of their products as well as a cross reference table. This link lists ALL known cross references for the K&N HP-1005 filter. You can search any auto parts store' website to source these filters:

K&N Filters HP-1005 Oil Filter Cross Reference Shart

I personally cannot give a 100% accurate answer on this. I have not seen a Injen Kit installed on a 370z personally. I have seen ALOT of Stillen units, which is the only long tube intake I can vouch for.

Based from the pics I have seen online of the Injen kit and its installtion. I do not forsee a problem. Since the filters are relocated into the fender wells, beneath the headlights. You will not have the complications associated with routing the oil cooler lines around the filters like with the STILLEN GEN III Intake Kit. The only part I am not sure of is the replacement windshield washer bottle supplied with the kit. You may have to route the lines around the new washer bottle. Stillen, Nissan Motorsports and our Z1 Oil Cooler Kits come with plenty of line, so you can easily re-route the lines as needed.

I hope that this answers your question!

Definitely appreciate you aggregating all of the information together.. I know most look to Nissan branded products to consider especially in regards to warranty.. this one being a phenomenon as we all sit on the same playing field in regards to non-specific coverage with the factory warranty on an oil cooler, whether it's any of ours.

There is the extra step of compliance with a dealer installing it, but definitely not the time to look at something with the chance of a failure, a quality kit like these should be considered.. there have been failures with other off-brand kits, and some of them catastrophic.. :/

I have to admit though, I wish I could use the regular filters like your kit. It is kind of frustrating that the only thing restricting the Stillen supplied thermostatic plate is that one spot where the sealing lip gets thin which means you have to choose a filter with a wider seal.

No problem. I think as more and more of these products come on the market, it will become increasing important for everyone to know the differences between the kits so that they will be able to make a more educated decision before they purchase.

As far as the warranty comments are concerned. The Nissan Motorsports kit is considered as a "Race Application Part" [Nissan Motorsports will even admit this]. Therefor it is NOT covered under the Nissan Factory Warranty. It will be up to the dealer to warranty the product and the car once the kit is installed. What is even funnier [to me atleast] is that most dealerships do not even know of this kit or have a clue as to its Nissan Part # to even begin to order it.

I agree, many dealerships did not even know of the heating problem. Also when my kit was order, there was not a part number for it. It was a back order item. Also most dealership do not have a tech that knows how to install the kit. For me to get this kit was a hassle to get, even though I got it free. I also let them install it because they told me it won’t affect my warranty. The dealership did take long to install, just the fact that it was the first Oil Cooler they had install for the 370z, they did an ok job, the only thing I did bitch about was, many missing screws. The reason I know, is the following day I dismantle my car to put a fender brace and notice all the screws missing, and there where many.

Wouldn't Nissan appreciate installing an oil cooler, at least in the short term? Keeping the oil within its ideal operating temperature improves wear and tear on the internals of the engine.

My dealership was very willing to install the oil cooler and said no reputable Nissan dealership would deny warranty claims if the oil cooler was installed. They saw it as a preventative mod to the car.

Make money hungry for lunch :), lol just kidding


Question
How does Motorsports Oil Cooler vs. Stillen Race Oil Cooler pair up?? they also have a race version??

Awwh come on Creators this sounds like a non perfected product though they are still good, what i mean is how come "Motorsports Oil Cooler and Stillen Oil Cooler" complete the kit with everything that you need plus the thermostatic plate to avoid separate installs and be price Efficient???

please dont get me wrong but this just reminds me of the car guys that i grew up around who basically ended up with frankenstein cars after so many parts that should have been added since the knowledge was already known from the beginning!??

Isn't it a 78.5% increase in surface area..? Just did the math..

Almost three years later and people still don't get it...

Sorry Dustin I forgot to answer your question. My sessions are 25 minutes long. I do a warm up lap and cool down lap and everything in between is go, go, go. I am doing an event this weekend and the temps will be 101-103 degrees and the Nismo will not get over 225 degrees. It is a beautiful thing.

Did not see this mentioned, maybe I missed it on the previous pages, but can the extended oil filters be used?

i.e. Purolator Pure One extended oil filter part # PL14610

I just ordered two 25 row coolers w/thermostat and plastic coated lines from John @ Z1 Motorsports during their one day Black Friday sale. Anyone sitting on the fence should take advantage of the savings, today only. :tup:

Great info, this is exactly the answer I was looking for!

You'll need to add SIX quarts. I have an oil cooler from Z1 and when my Nissan dealer changed the oil with 5 quarts I was running a bit warm. Checked the oil, added one quart, all is well. Recently drove when the outside temperature gauge in the car said 109 degrees. Oil never went above 220 whether stop and go or traveling at 70+.

Obviously you don't track your car very much. The price for the Nismo kit is totally justified. I bought mine 3 years ago - first ever design as I understand it, for the NISMO cooler, totally - best $$$$$$ I ever spent. ;-)

Cheers

Just added a Greddy turbo oil pan (no I don't have a turbo/supercharger setup) to my Nismo and it is wonderful - more oil holding on major G turns and now starvation issues should go away. Especially since I will be at COTA next month again. Yahoo!!!!!! Now the system takes Up 7 1/2 quarts (Nismo stock 36 row cooler) for an oil change. Ching-ching!!!!!!!! $$$$$$$$$$

The '09 NISMO does not have a "stock" oil cooler....and it is definitly not a 36 row. Your information is off or you are confused somewhat. There is an aftermarket NISSAN MOTORSPORTS Oil Cooler. But even that is not a 36 row...it is a 34 row.

I just bought the Stillen 19 row for my supercharged Z. Its -21c here in Indiana and I was going to wait untill spring/summer. But I noticed a noticable increase in oil temp when going less than 10 mph around my neighborhood for a period of time. It should be here in time for valentines day! But do you think i should of opted for the 25 row? I take it to the 1/8 drag strip every now and then, but am kinda worried now that the 19 row will be useless for that hard racing.

Apparently you haven't read the entire thread. :shakes head:

While he misquoted the row size, the comment referred to the Nissan oil cooler he had installed.

Dude, I bought a Nismo 34 row cooler 2 weeks after buying my car in 09. I got it directly from Nismo in Japan - through my dealer. They made it special - the first order they ever had for one. I was trying to keep my warranty in tact for the car. :tiphat:

Thank you. :icon18:

And yes my bad - 34 not 36 row.
