Jackson Racing engine oil cooler for NA applications

Yup. Smaller ones won't be an issue, and ones big enough to break through... well... that would break a radiator too.

This is only really an issue for guys that are tracking, canyoning, or are FI (and the shenanigans that come with having FI)

Just a few weeks ago while traveling to a SCCA event. One of my friends had a rock fly up and puncture his S2000 CR radiator which in turn drained the radiator and warped the head.

Shit happens.

@CSG Mike I was looking at the Mishimoto tstat oil cooler would there be a problem using that cooler with the JR SC kit? Would you recommend the JR cooler over the mishimoto?

Compare the sizes of the cooler cores and/or the BTU ratings. I'd recommend spending the extra cash for the JR cooler, but having the Mishimoto is far better than having nothing.

Has anyone experience minor seepage from the AN fittings coming out of the mocal sandwich plate? Just noticed yesterday at the track, used a dental mirror and saw some oil residue at the bottom of each, a tiny bit at the washer to plate seal and a tiny bit at the male to female AN. @CSG Mike have you noticed this with any of your installs?

Can you explain please. The Jackson cooler is 15 row, the Mishimoto cooler is 19 row. Would 19 rows be bigger and cool as good or better?

You have to look at dimensions and capacity not just rows.

Not sure if this is the correct interpretation but I believe the Setrab one, though 4 rows short, is less restrictive and has a higher flow rate overall? But it is true that the mishi one has a higher surface area so it's hard to isolate the net effect...

The AN fittings should not be leaking. Did you tighten the fittings that go into the Mocal sandwich plate? They do not come pre-tightened, so each fitting needs to be tightened twice, once on each side of the fitting.

The Setrab core used by the Jacking Racing kit is both thicker, and wider. The net volume is approximately 50% higher. The fin density is also significantly higher.

This is, assuming, Mishimoto hasn't changed their design.

You should check the fittings on your Mishimoto from time to time.

Thanks for your response mike - tightened both sides up during the install. It's never enough oil to form a drop or stream of oil but it clearly is seeping a tiny, tiny bit. Probably comes out more at the track. Will give JR a call to see what they say.

I have seen *one* instance where the Mocal sandwich plate had a factory defect, and I've seen hundreds of Mocals. It's unlikely, but never say never.

So it's more likely not the plate itself but the -10 AN fittings. There is slight residue on the underside of the fitting where the male and female AN fittings meet on both ports.

There is slight residue on the dowty of the driver side fitting, which suggests either issue with the dowty seal or the mating surface of the plate.

These shouldn't be torqued very hard, correct? 15-20 lbs?
