I'm trying to piece together an oil cooler setup (hopefully for Expo use) but I keep getting conflicting information. Some say you can't use a sandwhich adapter on an R, but while searching I came across one using a Mocal sandwhich plate .

I'd prefer not to run a remote filter for the simple sake of saving time and money. I currently have the engine removed if on-car installation has anything to do with the problem.

I use one with the stock oil cooler in place.

 

I believe greddy sells a universal one if 'm not mistaken.

I use this one for Oil pressure/oil temperature gauges and oil cooler.

Just make sure that it is the new ones, like the universal Mr. Miyagi mentioned above. The 1st gen GReddy ones, made for specific cars, will NOT clear the OEM oil cooler.

Me too. Left the stock unit in place and just screwed the adaper plate right on top of it. The stock unit can act as an 'oil warmer' on cold track days, and help your air-to-oil external unit with a little extra cooling on hot days.

 

I have an idea. How about bypassing some colder coolant (maybe directly from the front radiator) to the stock oil cooler when the oil is getting hot.

In the stock setup the coolant is too hot to cool the oil during trackdays.

You don't want excessively high coolant temps either. Oil temps are gonna get up to 260, hotter than your coolant should ever get. If you start bypassing the radiator to cool the oil, the water temps in the engine are going to go up. The stock system is 'pretty good'.

Oil cooler == teh win!

Isn't it already warming up the coolant water with the stock setup?

Coolant == Water.

Coolant "can" warm up the oil, I suppose, especially in a car with an air-oil oil cooler, or while it's warming up and the thermostat is closed. Generally, I'd expect oil to get a lot hotter than the coolant on the track.

Race cars run WATER, which boils at about 100 degrees C at atmospheric pressure. You squeeze a few more degrees out of it by holding pressure in your cooling system (with high pressure radiator caps etc.). Oil temps can see 260-280, and your water will never get that hot.



Couldn't find a graph above 100 degrees C, but water's vapor pressure goes up quick from there.

I don't think you understand what I mean.

With the stock setup, coolant (water) is going into the stock oil cooler to warm up the oil if the oil is colder than the coolant. And if the oil is hotter than the coolant, the coolant will be warmed up by the oil, and the oil therefore cooled by the coolant.

But the problem is, the coolant is too hot (90 C) to cool the oil at trackdays.
What I want is, that when the oil is colder then 90 Celcius, I want 90 C hot coolant going into the stock oil cooler.
But when the oil gets hotter than 110 Celcius, I want 30-40 deg. Celcius coolant water (somehow bypass it) going into the stock oil cooler, instead of 90-100 deg. C coolant water. In this case I won't be needing a separate oil cooler so soon.

</TD></TR></TABLE>Not true-- if your water is 90, and your oil is 130, that's enough of a gap to do some cooling/heat exchanging.

But then you'll boil the coolant in the engine and overheat the motor! Your car would be constantly bypassing (partially) the radiator to cool the oil more, and even with a racing radiator you'd probably end up with superheated coolant in the engine, which would start boiling, and your cylinders will crack or you'll warp your head or poke an eye out!



I understand what you're saying, and it could be done, but I think keeping the coolant cool running through the engine, is more important than keeping your oil cool.

Apparantly it's not enough, because the oil is getting hotter and hotter. The colder the coolant that is going into the oil cooler the better (for trackdays, not for street)

If you consider the whole engine that is heating up the coolant, then the stock oil cooler is just a tiny heat source. You could just route the coolant exit of the oil cooler back to the radiator.

They are both important. The pistons are not cooled by the coolant but by the oil.

 

I have the Greddy oil filter adapter plate installed on mine and it works great. It has about four bungs, just enough for my gueages and my line for my cooler. Just my $.02

 

I also have the GReddy sandwich plate, mine has two bungs for temp and pressure sensors and one for an oil feed for oil cooler or turbo or whatever. Works a treat and clears the oE oil cooler no problem.

 

Thanks for the info guys. The Greddy adapter sounds nice especially since I plan on hooking up an electric oil temp and pressure gauge.

 

Greddy adapter works fine w/ ITR:





I got mine from http://www.importparts.com. Here's the part number and model info:

1 x Greddy Oil Block Adapter UNIVERSAL M20 X P1.5 70 (Honda,Mazda,Mitsubishi & Subaru) (GRE-12002733) = $57.80

 

i'm using the MOCAL sandwich adapter with built in thermostat, should be nice this summer!
