Thought I would share a picture of the connections on the CSF auto radiator.

There are a couple ways you could do this but we keep these in stock. We also have our Z1 oil cooler kits if you wanted a standalone cooler. This option is very similar to what Nissan added on later models but a little different because you are running the oil to the coolant instead of coolant to the oil.

Chuck, thanks for the pictures! I assume the trans-cooler ports, which I want to use for oil cooling, are the two smaller ports that are flared at the ends, right? I have thought about the air-to-air, but my preference would be for something more space efficient since I plan to go FI eventually. I don't think anyone has tried this yet so I hope to get it to work successfully.

Beta tester discount? J/K.

There has been some discussion on this over on my vette forum. Interesting to note that '76 L-82 vettes, and some other model years, came from the factory with a 160 thermostat. Base engines had 180 I believe. Hotter running engines are more emissions friendly but a colder running engine is better for performance, so the debate goes on the vette forum. Knowledgeable folks, like engineers, agree that 160 is the minimum oil temp to protect the engine and 180 may be about ideal.

According to a few engine building books I've read through, 175* oil will tend to net a few extra whp on an engine dyno, so the 180* cut off for maximum power is probably bang on.

It's just tough to maintain EXACTLY 180* it seems. A lot of the guys running air cooled oil coolers have to use block off plates in the winter to get the oil up to the 180* region, and they tend to see the oil take longer to get up to temp the rest of the year.

I think the best set up for a DD would be a water cooled 200*F tstat oil cooler. I think a big air cooled one is over kill on a DD.

I've been just adding metal fins to my oil pan (the Arc "cool fins") and they work remarkably well. I never see over 225* F beating on it in the summer, and cool down time is fast. Typical driving temps (which are always a little "spirited") I see around 185* - 208*.

As to the thermostat on the older 'vettes, that was probably set for dino oil ideals.

Modern synthetics can really hold together as high as 280*- 300*+ before catastrophic engine failure is a serious risk (or so I've read), but Nissan is wise to shut down the engine well before it ever gets anywhere near that.

I'd like to see the oil temp effect of the CSF radiator. During spirited driving and in traffic.

Where are you sourcing your ARC cool fins?

Yes the two small flared ports are for the transmission cooler.

We have seen decreased temps across the board when adding the upgraded radiator. If you are planning to go FI in the future I would suggest the external cooler but for daily driving this would be neat.

Hate to bump an old thread.... but did anyone try this?
