Cusco Oil Cooler
 

Wasnt quite sure where to put this, but thought here with the FI stuff might be okay. Cusco released their oil cooler (MT only) for the FRS/BRZ last night. Instead of another radiator surface, theirs links into the normal radiator piping for the car and runs on a plate at your oil filter to cool the oil. The Japanese website can be found below.

What are people's thoughts on this? Is it a viable option for keeping the oil cool in hotter areas? It seems inviting with its lack of adding another system in front of the radiator.

Quoted from their website (using the translation from google chrome) -
"Benefits of water-cooled engine oil cooler
· Since the cooling based on the cooling water circulation system by the radiator with a high and stable cooling performance is provided to the original car engine oil cooling stable and reliable at all times is possible.
• Because not install the radiator core cooling before air-cooled air conditioning capacitor like, there is almost no impact on the performance of the radiator cooling and air conditioning .
-Oil line to the core without cooling air-cooled like longer, because there is almost an extension of the oil line or increase the load on the hydraulic system, there is almost no degradation of reliability, such as oil leaks . By keeping a high pressure also you can normally performed properly to ensure lubrication and cooling of the engine oil circulation .
• You can run, unlike air-cooled engine oil cooling is carried out by circulating cooling water if the engine is spinning without relying on the traveling wind . Of engine oil cooling is possible even when the vehicle is stopped or when congestion that is midsummer.
· Unlike the air-cooled engine oil cooling is possible even in the running efficiently (under high outside temperature) hot summer . On the other hand it is possible to warm the engine oil with an increase in temperature of the cooling water (ambient temperature conditions is low) (early warm-up) winter . That remain stable until early speedy suitable temperature is raised to the temperature of the engine oil at low temperatures even when I can.
• In the event of a crash at the time of the event of circuit racing, such as air-cooled oil cooler mounted in the bumper type oil would leak such as rupture of the oil lines and the oil cooler core damage even seemingly minor crash risk of being non-self-propelled entails. Water-cooled engine oil cooler Cusco is also safe when I crash the event of not mounted in the bumper. Also does not require any processing of the bumper also. It is easy to mount in the engine room .

Eliminate the disadvantages of water-cooled oil cooler!
Testing water temperature is also reduced further.

☆ though it is reasonable and easy to install water-cooled! Outstanding reliability.
⇒ and tested thoroughly studied the circular configuration of the 86 & BRZ engine and type FA20, providing the core cooling water-cooled in the engine oil filter with engine oil cooler water-cooled 86 & BRZ Cusco prevent a loss of oil pressure and less oil piping, cooling water at the same time We also provide ease of installation when installed together to achieve high reliability and low cost performance and by the shortest distance lines may also have.
Water-cooled oil cooler typical structural core complex and expensive cooling, cooling water piping oil separate dedicated more complex models to increase the price further . Also decreases reliability by desorption cumbersome and also accompanied by a significant part of mounting the minute, increase the pipe. Dazzling them I have to eliminate the disadvantages .

☆ demonstrate the effect on the test circuit, the synergistic effect also decreases water temperature more!
⇒ actual driving tests on the track by Honjo (vehicles equipped with supercharged Cusco) Cusco 86 demo car. Car not installed water-cooled engine oil cooler Cusco oil temperature rises to about 130 ° around each time laps . Vehicles equipped with water-cooled oil cooler oil temperature stable Cusco (110 ~ 115 ℃) about near constant value even laps were.
There are differences even water temperature was measured at the same time further vehicles not mounted engine oil cooler, water-cooled Cusco increases with oil temperature with each lap, stable at just before 100 ℃ although, vehicles equipped with engine oil cooler, water-cooled Cusco is not I am about 5 ℃ low temperature stable than vehicles equipped with the.
Reason and stable temperature water temperature is lower by mounting of the engine oil cooler, water-cooled Cusco, there are two air bubbles' ※ cavitation by bypassing part in front thermostat cooling water line dedicated to the oil cooler in the cooling water ( heat dissipation effect of the cooling water was bypassed by exposing the body to the outside away from the hot engine cooling water lines can be increased further since point) 'is suppressed. ※ phenomenon of cooling performance is reduced fine bubble cavitation occurs in the cooling water =. Original performance can not be exhibited absorption and heat dissipation performance of the cooling water is reduced by prone near the thermostat and water pump change is likely to occur in the water flow and pressure of the cooling water, foam is generated."

this will just make me need a bigger radiator

This and a Koyo radiator sound like a winner to me (pending actual cooling data).

BUT, still freaking expensive.

I would prefer a system like this on a DD car, many people do not realize the danger in OVER cooling the oil in their cars. Oil needs to get hot enough to boil out the fuel and water tat accumulates, not to mention operating temp dictates viscosity...blah blah blah...

As gm... I mean Huehuecoyotl pointed out you are adding more heat to the water cooling system with this product, so make sure there is head room there....but this will obviously work well with an upgraded Radiator aswell...so plan accordingly...

I agree, definitely expensive, though the FBM cooler is $650, and Perrin is $690 (cusco is roughly $600 before shipping). But seems like it would keep clutter down. I am interested..dont know if i can justify the cost though...

I second this. A bigger radiator would seem necessary as the oem version is not designed handle that much work. But this style system does sound appealing.

As normal time will tell. I'll let someone else be the lab rat on this one.

Any thoughts from others as to how well this would work?

This is how my 1.8t cools itself. I can build a air cooled oil cooler for loads less than 650. Setrab makes an sandwich plate. http://www.setrabusa.com/oilfilteradapters.html

I like the design. I think it should have come on the car stock. For DD, I think it would be great. For track days.... I'm not so sure. Water to oil coolers are much more efficient than the radiator type, but the heat exchanger on this unit is so small I am not sure it is up to the task of driving on the track. Perhaps someone who knows more will chime in soon.

How hard is it to search for "cusco oil cooler"

Very much like the stock cooler on a K20. Why this isn't standard equipment I don't know.

No need to be mean about it. That thread hasn't been touched the 2nd of April, and the information I found was in a press release for the supercharger, dated 15April2013. I had no reason to attempt a search when I felt I had new information to share with everyone.

That other thread has no useful information in it anyway. We need someone to get one, or some data from Cusco, or something...

Hmm, in for more info

Got the same flyer in english. Still doesnt give us any real world results, but its a much better translation of the information than what i'd posted before. The MSRP they post on this is crazy high though, especially if you compare it to converted yen price posted next to it.

gotta love all the marketing this site gets pumped with to wow you to swipe. SO many numbers, colors, from every vendor, but so little that actually matters...

That's the actual cooler unit, which is OEM on the 02-05 WRX. Like I said in the other thread, this is not a replacement for a real oil cooler where you are seeing very high oil temps like on a track.

If you want a water/oil heat exchanger, then Mocal make them called 'laminova'...

Most of the oil cooler kits you can buy today use Mocal exchangers, so should be fairly reliable.

http://www.stratosec.com/www.stratos...1&d=1264497241

Wonder why the Cusco only fits manual transmissions, also mentions you have to cut the radiator hose. I'll stick with the Perrin kit although if somebody wants one of these let me know i'm interested to check it out.

hey the one positive thing I LIKE about the Mocal laminova and really like alot about the CUSCO is for guys going FI and having a FMIC, I had to get creative if you want to stick to giving the FMIC 1st dibbs at air flow. I mean if you PLAN to get a bigger radiator anyways, I can see how a a cusco oil cooler or the one ft_sjo posted could help, but I like the easy replacement/upgrade/inspection of the more traditional style of row cooler with sandwich plate. Lots of folks feel fine putting something in front of their fmic, not me

for those of you who see a true 4 seasons, water to oil may be better. I like the simple option to run a bigger oil cooler core if needed as my power level continues to grow

Exactly ^^

Kinda' overpriced based on current exchange rates, should be about $600.

If your going to get another radiator, have a cooler put in the drivers side tank. That is what I've used for years. It simplifies and shortens the oil lines.

I hit 130c / 265f on my car today and ambient was only 18/65. :(

Been pondering where to fit a core around my AVO kit for a while but didn't come up with anything I'm happy with yet.

only see temps like that out on track never ever on street

Yea, I don't crack 220* F on spirited driving in 60-70*....

I am confused... Does this thing have a 266F thermostat? So the oil has to get up to 266F before the thermostat lets oil flow through the core?

I don't think the oil temp ever gets that high.... even the track and turbo guys don't see those temps do they?

In the original posts picture you can see a diamond snapped adapter on the left. The auto has a tranny cooler stock and the line splits where the adapter connects. So if you replace the split for the AT cooler that wouldn't be good.

Cusco stated they are looking into an AT version when I spoke to their rep at ToyotaFest/86DDA.

Does the Subaru OEM part for the WRX/STI/Legacy fit the BRZ, and if so what does the Cusco part really offer?

I can pick up the OEM unit for ~$220, so all I need are small coolant lines which is relatively simple.

you still need the adapter cusco provides unless you can machine your own. It is usually best to just bite the bullet and buy the kit.

I bet a cheaper version could be done using 2014 (edited) Forester XT parts. It has a factory oil cooler, assuming because it is turbo.

http://www.hybridautocar.com/wp-cont...e-1024x682.jpg

*2014. Didn't come to mind for some reason. I can't find a parts list online (2013 and older only), but if someone could pull up costs for the cooler and associated lines that'd be great.

Right on,
Combining both of these together seems to equal RobiSpecs Radiator and oil cooler.

Which uses a LARGE radiator with an oil cooler,
and a sandwich plate oil adapter.
This will warm the oil faster.
Aswell as keeping oil temps on par to coolant temp.
Coolant temp would be more stable due to the increased capacity and efficiency.
No worries of over cooling.
Two Birds, One Stone.

I'm in no way affiliated with Robispec.
Just think this is THE way to go.

I actually bought his cooler, we agreed he sent me the cooler that was running on his car because he was not able get new cores for when I needed it. Unfortunately, the brackets to hold the radiator to the frame did not match the holes. Same thing with the brackets to hold the Evaporator to the radiator. I ended up returning it for a full refund and will wait for a different solution later on.

did you consider the Koyo ?

Seem he did/is.

Yes, next best option for me is the Koyo radiator with some Oil cooler that is not front mounted.

Would you go back to robispec pending fitment issues?

whoops, missed that.

NLM full-blown build that just started has a koyo with a small front mounted cooler, i wonder how it would function

Honestly, no. Although I do agree the best solution is to cool the oil with coolant and have a bigger radiator, it is too big. If this was a track ONLY car, then yes, I would go for it and hack away whatever is needed to fit it and other nearby components. But the radiator being so big, introduces other limitations like for example not being able to run a CAI like Perrin's because the radiator is not only thicker but taller and the CAI tube would not fit.

I have a 13 row oil cooler and can get the lines made in the length I need. But I need a sadwich plate. Do any of the ones listed at that setrabusa site work or does anyone know where I can get one that fits our car? Thanks!
