They've been offering this for two years now. You can get this part as a seperate NISMO part and I don't think this is the same oil cooler that's in the 12 Z's this is an actual racing cooler.

No sir it is not. Also not covered under factory warranty if installed.

yeah...it's not a water to oil cooler!

We have the Nissan Motorsports Oil Cooler -- 5 in stock!

Nismo Racing Oil Cooler Kit Nissan 370Z - 21300-SS370 - Nismo

i've never seen a water to oil cooler

Scott

have ever seen a car before? they are very common.


This cooler is obviously passing coolant, as you can see.

There are about 5 threads all talking about the same thing at the same time. :icon14:

Overall, superior. Faster warm up to ideal operating temp, easier to maintain ideal temps. Water does a much better job than air of absorbing heat.

Someone from Nissan actually called me regarding my query on this for those of us with 2009-2011 models... will report back after I return the call.

If water cooled is better then why hasn't any aftermarket companies design one that is water cooled for our cars? That was one of the things that had me thinking.

Because it generally costs more, there is a bit more r&d from what I gather...

Please correct me if I'm wrong on this.

The same reason that some cars were once air cooled -- fewer parts required, and therefore less cost.

But most of us (outside of fans old Porsches) prefer water cooled motors...

It's more of a debate with intercoolers for FI applications because cooler really is always better, and in some situations, air-to-air coolers will work as well or better as water-to-air.

For oil, cooler is not always better. Geting up to operating temp quickly and being able to stay there with little fluctuation is ideal.

Because it probably requires modding the radiator

It's inferior in terms of cooling, superior in consitency.

The two smaller temperature deltas make cooling through the rad less efficient.

Well... right. But cooler isn't always better -- I'm thinking specifically in terms of what would be ideal ("superior") for a DD; for a track only car, air is fine, notwithstanding leak issues.

...

Actually, I just found your commentary on this in another thread, and we are on the same page in terms of what kind of cooler tends to work best for a given application :tup:

Hey -- hang on -- did I just read that the cooler isn't easily backwards compatable!? :icon14:

Is the radiator P/N the same for the new cars? I don't understand why you can't just plumb it in if it makes use if existing lines.

It can't be that different?! :shakes head:

At this point we don't know. Unknown's service manager says it is not backwards compatible---I will reserve judgment until after I see it.

The oil cooler lines are usually a lot smaller, so you would have to tee after your current radiator lines into a smaller one. Can you say, coolant leak?

You wont necessarily have a coolant leak. It's pretty easy to seal coolant hoses. I would not tap into one though, you could find an inline hose adapter, although the sizing of the ports needs to be big enough.

Something like the coolant tee at the bottom of the link below.
