New England driver so still cool outside, normally oil in low 200's, but noticed immediately after short period aggressive driving oil temp very quickly jumps up 20-30 degree's in just a couple minutes- may be a problem come summer- other than that all good

$780!!!! FOR THAT?! No... Sorry, but Nissan should have included the oil cooler in the car to begin with. It's a $100 part in cost. It wouldn't have hurt them to add it.

Not quite $100. The photo in the link above looks like a series 6 25 row Setrab. That's about $225. The fittings appear to be AN10's. A decent swivel and reusable AN10 90 degree runs about $25 each. Add the sandwich plate adapter, the hoses, the Setrab adapter plates and labor for hose assembly to the above.
I do agree that Nissan should have included it with the car. I would have paid an extra $500 for the cooler if they had it as an option without blinking.

BTW, Stillen's kit is really looking like a pretty good deal!

just past the breakin now im done granny shifting at 3k and back to my normal shifting at 4k-5k and my itch to always redline and go (not slow-lol)
tonight i saw 240 for the first time
it got me thinking i really need to bump my oil cooler up my list to buy

nissan needs to get to this and get a fix

*crosses fingers**

Here's the latest data from our oil temp survey thread (here http://www.the370z.com/nissan-370z-g...html#post66299)... thanks to everyone that has taken it so far!

I went to town up and down the halls of STILLEN after everyone up to and including Steve Millen to keep the cost of this kit as low as was possible..

And while a bigger cooler can be built, obviously, this is in our opinion more than enough to handle virtually all driving needs for the 370Z, up to and including track use. It was built to spec to give maximum cooling at the lowest cost possible, utilizing a blend of super quality components like the SETRAB cooler and Goodrich stainless lines, down to the custom brackets, PS cooler relocation hardware, etc.

It's nice to see the guys with the STILLEN cooler seeing the benefits after testing and hard use.. and I would anticipate additional feedback from guys soon, as I know a number are embarking on trips to the track soon..

Got my Stillen kit installed today ! track day Sunday ! :)

In addition to the kit, I think we will all benefit from some additional time on motor and maybe switching to a more efficient motor oil

Just to make sure there's no confusion, the oil cooler pictured in that article is not the upcoming Nismo cooler. They explicitly state that in the article.

That's the prices at retail cost. But when you're a manufacturer, you can cut the prices by nearly 3/4. For example, good DVI cables for video sell for about 50-70 bucks, but the retail cost is around $3.00!

If Nissan manufacturered their own oil coolers, the prices on them would have been astoundingly lower.

It was 88 to 90 degrees yesterday and I saw a steady 230 degrees in oil temp just cruising around town.. this seems ludacris, but I also don't know what temps are considered dangerous and which temps are in the safe zone.

It's not really dangerous until you are continuously riding near or above 260. At that point there is a risk to bearings.

230 isn't bad itself, but it is when you consider that temp was while cruising. Once you step the RPM's up the oil temp is going to go up with it.

Same here, I'm in Charleston and the temps and humidity are not too far off from Jax. I am still in break-in. I am reasonably certain that once I begin pushing the RPMs as the car was meant to be driven, in our weather, temps will be far too high to be safe and allow longevity to the engine.

John

Crash,

It would be nice if it were that simple. But to be honest I don't see how you could price a Setrab cooler at 75% off the already discounted $225. That would indicated a cost of around $56. You couldn't buy the raw materials and stamp the plates for that amount of money.

For grins, call a BMW parts department and price a cooler for a 335i. It will be a rude awakening. Or just go online and add up the parts. Don't forget to add in a tube of Neosporin. If you have never put together AN fittings and SS hose your fingers are going to hate you.

Have had the car for two days now, not pushing it (have shifted at 5k twice only from 2-3), and my temps have not passed 220 yet, thankfully. I am still under 200 miles so it will be a few weeks before I get her opened up, but in Houston it has been getting humid and warmer lately so if I start seeing this creep up during the break in period with me shifting <4k, I will be putting in my call.

what about this little guy? Only $120.

B&M 70270 - B&M SuperCooler Oil Coolers

I don't know what core that is, could be a great one, could be crappy. The Setrab cores that the Stillen and Nissan Motorsports kits are using are a solid, well-proven design though. Also, that kit looks like it uses plain rubber hose. It will "work", but personally I wouldn't trust a plain rubber hose for something as critical as oil cooler lines. If they burst, or a cheap hose-clamp connection leaks or breaks loose, or something rubs on them and cuts them, or even wears a weak spot in it (leading to a burst)... it takes a very very short window of time to destroy your engine once your oil starts dumping on the ground from such a failure. Good quality hoses (and attention paid to the details of routing and protecting them) are a must for an oil cooler.

In a somewhat related incident from my past, I once had a transmission cooler on a TH400 auto tranny on an 81 Firebird that was run up to the front with rubber hoses like that. A few thousand miles after install, when I was pretty confident it was holding up well, I was on a long highway cruise in the middle of summer. Running down a highway between towns with no exit or service station in sight, one of the hoses blew out. I heard it and immediately shut the car down onto the shoulder and turned it off, but it wasn't fast enough to save anything.

2 Hours on the roadside waiting for a tow truck, a *long* tow back to the nearest large town, and refilled the fluid, but the tranny was dead. Had to do a complete rebuild on it. :shakes head:

Moral of the story: don't skimp out on hoses and connections for critical fluids.
