I looked into this and almost bought one for my car, but then I was told it was a complete nightmare on the Berk 135i race car.

Yeah I think I read that post too. Sounded like they maxed out their radiator, but that's a whole other platform, so maybe they were already very close to needing a bigger radiator. Correct me if I'm wrong, but I don't think any NA 370Zs are having any sort of coolant overheating issues. It seems like our radiator is not very close to being maxed out, so hopefully there is enough wiggle room to put a little more load on it.

I found that the Laminova oil coolers can be bought directly from Laminova for quite a bit cheaper. I was originally under the impression that Laminova just made the cores and that Mocal was building the oil cooler housing around them, but I guess not.

I've got a bunch of other immediate expenses to deal with at the moment, but when I get some extra cash put aside, I think I'm going to go ahead and give this a try.

If I remember correctly the price for an assembled core was around $700.

The price is right there in the link in my above post as $323 for the oil cooler I'm looking at. Granted i still need some hoses and a oil filter sandwich plate adapter, but I don't think that's going to end up anywhere near 700.

pending on how long you want to wait, contact nissan north america. I got mine from them due to the fact that my car was running 240s from the get go. I got the 34 row cooler kit installed and a oil change at $0 cost. I think they want me to keep purchasing nissans lol. But I purchased my thermo adapter plate from gtm and ordered my an10 fittings from mocal so i can keep my an-10 lines. GTM wanted to charge me almost 900 for hoses and fittings and labor and plus it would be a smaller line. No thanx. :D

I called and talked to them directly..the one they recommended for the car with the right diameter adapters and everything came out to ~$700 and Im not sure that included lines or anything... I asked about ordering 10 of them and I think the price went down to $500. They don't stock pre-assembled ones, everything is made to order...

I know whats up...youre talking about laminova and Im talking about C&R Racing...

Ah ok, yeah I've mainly been talking about Laminova, but I did post the C&R pics from AM performance just to show that there is obviously some merit to oil-water based cooling setups. I sent the AM performance guys a PM asking for some input on why they chose the C&R or any other information on their setup but never got a reply.

The Laminova still looks like a very solid design to me and I think it has more surface area that the c&r because of the thousands of little fins on this thing.

I'm currently considering the Laminova C43-332 (43mm diameter core, 332mm length). Though they do have larger 54mm core versions which are more expensive (and even double core setups). I just sent an email to Laminova asking if they had any sort of recommendations as far as oil cooler sizing goes, so we'll see if they get back to me.

Actually water is more efficent at transfering heat. Plus you can mount the heat exchanger anywhere you like , yes plumbing will be tricky.
Also coolant temp exits the radiator at around 165 degress so this will quite good for the oil temps plus you reach operating temp sooner. The oil temps will be very consistent.

Has anyone made a move on this yet... I would be very interested in the results!

Can anyone confirm this? ^^^

Strongly considering going the coolant to oil cooler route and want to make sure I have a solid game plan before moving forward.

Right now I'm planning on going with the C43 core with a 330 mm length. According to Bat, Inc. that cooler should be equivalent to a 25-30 row air to oil cooler. Currently leaning towards a non-thermostatic sandwich plate since the radiator coolant will prevent overcooling. Also going to get actual hydraulic hoses with crimped ends in lieu of the push on stuff just for the added security.

Before anyone says just get the air to oil coolers, the Z is used for AutoX where the air cooler won't have air flow between runs.

Water can absorb way more heat than air -- its the primary reason to have a water cooled rather than air cooled engine...

Laminovas are great on efficiency and space -- they tend to be a bit pricey tho.

Air cooled anything is only good on the basis of cost, simplicity, and weight savings -- otherwise, water wins every time.

is there still any interest on this?? sorry bringing this back for discussion

I purchased a laminova cooler recently, but haven't quite decided how to arrange this and route all the damn coolant and oil lines. At first I thought I could have it mostly vertical from the lower radiator hose to the engine inlet. But the thing is so long that it would be sticking out of my hood if I did that. Also this was under the assumption that I convert to aftermarket intake so the intake boxes are not in the way.

I guess my current idea is to lay it down along the bottom of the radiator, but then the coolant hose has to do a 180, and come back to the engine, the 180 pipes or silicone couplers are also really wide and have to worry about hitting the fan shrouds and crank pulley, and agh my brain is hurting again thinking about this.

I wish this thing had female NPT threads on the sides (like most other oil coolers and sandwich plate adapters) instead of these AN fittings because you could make it a lot more compact using something like this

rather than this sticking out of opposite sides.

I think I'm actually going to try drilling and tapping these AN flanges to convert them into NPT female fitting. I can maybe take some pics of how huge all this crap is later.

Yes. Faster oil warm up in the winter and constant cooling even at a standstill in the summer. Sounds great to me.

What I'd really love to see is a kit so that I don't have to piece mail this together. Most important parts would be molded radiator hoses to make this work.

What model did you get? Looking at their offering the longest one is only like 16" at most. Also did you plan on running this cooler with the stock radiator?

I am only seeing the benefits of the oil-water cooler in auto-x use here. For reference, I have a 34 row Setrab installed. No thermostatic adapter. In the cold months it sucks to have to start the car 10-15 minutes ahead of time, but wa no biggie after a few weeks. In the warm/hot months is where the larger cooler shines. Even if my car sat idle for an extended period of time, I never had any oil temp issues and I am in the people's republic of Texas.
