hi
for the turbocharged B18C1 motor, I want to install an oil cooler.

is an oil radiator enough ?
like this :




or should I need a sandwich adapter too for sure.?

should this cooling system have a thermostat ?

thanx

aether

i dont think a thermostat is necessary, but i dont think i understand the radiator or oil sandwich question...

Yes a themostat is necessary (its actually very important). OP, what are you using the car for ? On a street setup that cooler should be enough. You need a oil temperature gauge though really to tell. You will also be able to work out what grade of oil to run with it.

alperx

alright, I use castrol 10-60.

can I connect this oil cooler, somewhere between the inlet pipe of the turbo oil feed and the motor ?

rich7777

That maybe to thick. You NEED to know your oil temperature so you can work out what grade you need. Running a thick oil just because you think its what the car needs is a bad idea. It puts a lot of strain on the oil pump and can cause wear on the bearings (or even failure in some cases). If your seeing oil temps just over 130°c then a decent 10w 50 should do the trick.

Yes you can fit it. But you need to know what your oil temperature is and you need the thermostat.

ACtually, that's enough even for circuit racing. 2 things I remember when installing my oil cooler.

1) It needs its own air source. So don't place it behind anything like a radiator or intercooler. It needs to be lower to the ground or in a central location where you can get air consistantly and independently. (Usually down by the foglight area with the foglight area drilled out is good.

2) Don't use an oil relocation kit when doing this. the longer lines seemed to be a detriment to the system, and I lost oil to the cylinder head during some spirited driving at VIR.

An example of how I did mine. Car is not mine but has JDM Conversion.

thanks for the answers first of all..

my oil temp is around 120-130 degress celcius when boosting. (250-260 F)
my turbo is t3/t4, oil cooled only.
I'm not using an oil relocating kit..
The weather in my city in summer is around 90-100 degrees F (35-40 degrees C)
ok I'll put the oil cooler right where u say, which is logical of course..

so, Shodan, should I use anything like this ?



or can I fit it directly before the oil feed line of turbo. ? How does it make an effect to use the oil cooling sandwich adapter and not using it ?

I use ACL Race bearings, is 10-60 oil OK for street driving ?

Can't go before feed line of the turbo, but that sandwich plate can help. The oil temps you're experiencing are actually rather normal. Face it, its going to get that hot when its splayed on a rotating shaft at over 120,000rpms, regardless of outside ambient temp. As long as you're using good oil, you should be ok. You really don't need it, unless you're starting to race on a circuit course, as I do.

alperx

so if I dont have the plate, where do you want me to connect it ?
can you give an idea ? (input-output)

If your boosted, then knowing your oil temp is very important..

Also, some coolant temps are known to drop up to 20* when using an oil cooler which you dont want your engine to run too cool.. but oil/water temp gauges are needed as well.

This but with the thermostat http://www.ebay.co.uk/itm/MOCAL-OIL-...item5d2f3ca413

I would imagine that his coolant temps will be fine provinding his thermostat is fully working. I run a oil cooler on my car and its a lot colder over here compared to Turkey.

I've only used a plate. haven't used it any other way. The greddy one is actually pretty robust

you can use the oil pressure port.. run some -6 line from there to a tee.. add your sensor, then run the feed tfrom tee to the cooler.

I use an oil cooler. The way I did it was to run the a tee fitting after the oil has gone through the cooler. That way the oil also goes back to the motor as well

Thanx very much.
I'll try that, it's logical to me.
