I've been looking into oil cooler options for a while now, and couldn't find what I was looking. Does anyone know if someone makes a 4 port t-stat sandwich plate (2 AN fittings and 2 1 1/8npt)?.

EDIT: T-stat sandwich plate.

Thank you.

 

Look at cummins torque converter cooler. I think the fittings aren't what you are looking for but it is 4 port(as long as you mean 2 in and 2 out)

EDIT: I thought it said oil cooler. Not a sandwich plate.

Thanks. I edited my original post, forgot to say I was looking for a t-stat'd adapter.

 

Mocal and drill

Or mocal and use AN gauge adapters

 

Run oil temp in AN fittings.

 

Maybe this?

!!! Now I'm just trying to imagine so many things fitting in a small space

 

I was trying to piece together a DIYcooler kit, but it's not really coming out to be much cheaper than the Trackspeed kit. lol So maybe yeah, mocal and drill.

 

Ordered the trackspeed kit. Wallet hurts bad.

 

Trackspeed kit is cheaper than sum of the Setrab and Mocal parts. Even if you account for street prices being cheaper than MSRP.

 

That's what I found pretty quickly.

 

Personal opinion, based on a sample-size of one.

For a street application, I'm unimpressed with sandwich-plate adapters with internal thermostats. They seem to pass a fair bit of oil through the cooler even when cold, with the result that warmup takes an extremely long time under normal driving, even with a turbocharged engine.

 

That's what I've read. Unfortunately I don't drive the car much on the street these days (dad life), and the few times I drive it it's to a local car meet or track day / drift event every few weeks. If this was a daily or strictly street driven car I wouldn't bother with a cooler, but on the track with the turbo, the car needs it bad. The car hits 260 degree oil temp pretty quickly, and takes some time to drop during cool down laps. I also have the singular motorsports hood vents on the way, they look horrible, but the car needs all the cooling mods.

 

The alternative is a thermostat which, when it opens, will briefly starve the engine of oil pressure. You have to maintain flow through the core at all times so that pressure fluctuation never happens.

And yes, I priced the cooler kits as low as I could. It's the magic of volume purchasing

 

Savingtons of money

 

As mentioned it's flowing some oil through the core for a reason. The solution is to cover / block it off in the colder months. It's quite easy. There are some covers that snap on over the cooler. I've used cardboard and tape myself.

Moss Miata also sells an oil cooler shroud.

 

For a car that does actual track duty and is also driven on the street, a perfect solution.


My comment was mostly about the need (or lack thereof) for external oil coolers on pure street cars which, at most, might see an occasional AutoX.

When I was younger, and naive, I built my first turbo car. It was a 1.6, so no factory oil cooler. Didn't know much about oil and cooling, but figured that it was probably something I needed to do.

Started with a Mocal plate and a small Earl's unit. Even in the summertime in SoCal, my oil wasn't up to temp at the end of my 5 miles commute to work.

Plugged the thermostat in the fully open position, and installed an external thermostat. Same problem.

Eventually ripped the whole mess out and installed an OEM 1.8 cooler from a junkyard car. This was the ticket- temps came up quickly in the morning, and never thought about getting too high even when I was pushing the car hard through the canyons on the weekend.


Not relevant to track use, just a commentary for anyone who might be reading this thread and thinking "Well, since the racers all use oil coolers on their turbo cars, I should probably install one on mine." For such applications, that's a worse solution than doing nothing.
