Money is getting extremely tight right now, I am closing on a house soon and I got this twin turbo project going on. So I am really wary on making any unnecessary purchase's. So I need a oil cooler. I am not to fond with ebay parts, and with Good & Tights turbo built, those parts suprised me.

Just wanted everyones opinion of this oil cooler kit. Would you use it?

There is no thermostat.

 

If it had a thermostat, I'd use it. Looks like a nice unit. But living in the northeast, I know that oil temps don't get into the normal range for a looooooong time after start-up. Get a sandwich thermostat and swap out the adapter and you're good to go.

 

I have used the ebay ones sold by maxspeed. that one looks very similar. The thermostat thing is a concern for some, but I haven't noticed much issue in my oil taking too long to come up to temp. not to the point where it is a concern

 

I think I'm going to get one of those and add a thermostat plate to try it out.

 

I think the lack of a thermostat would be more of an issue if the Z didn't already have a built in oil warmer (or oil cooler, depending on which side of the aisle you're on).

My oil cooler kit has no thermostat, its never really concerned me.

 

So your justification for not being concerned about an oil cooler w/o a thermostat is that your car has an oil warmer? There are several things wrong with that. First, when the car is cold, especially in cold climates, the oil cooler will cool the oil further, as well as make the engine coolant colder, making the engine take even longer to warm up. So essentially, you're saying that the oil warmer offsets the oil cooler's excessive, uncontrolled cooling. So it follows that if you just don't install an aftermarket oil cooler, and just remove the OEM oil warmer (or cap off the lines), you'll be exactly where you are now. Logically, a thermostat makes sense. It is part of every car with a factory oil cooler, so maybe that means something, I don't know.

 

it means if you live somewhere it doesnt freeze, why get a thermostat?

 

It still takes longer for your oil to warm up. So unless you are willing to let your car idle for longer to warm up you are putting it at more risk until your oil warms up.

 

Its a double edged sword, just like a lot of modifications we make to our cars...

By your logic if you add oil capacity by using an oil pan spacer or larger oil pan you are putting your car at increased risk because the oil will take longer to come up to temp - but where are the thermostats in these setups? Of course there are none.

A thermostat is also just one more component to fail.

Also let it be known that I live in a climate that only gets as cold as about 45-50 degrees even in the middle of winter. If you live in a colder winter climate then yes a thermostat may be more of an issue to you. I also have a turbo which contributes to oil warming.

Really though, I think it is less of an issue regardless then some people would like you think, and generally these are the people who find some fault with every possible mod and who themselves drive a stock-ish car.

 

No, an extra quart of oil is NOTHING like the constant heat loss provided by an oil cooler. Would you like me to calculate how many BTUs it takes to raise the temperature of one quart of oil 100F? How do you suppose that compares to the BTUs an oil cooler removes from every drop of oil that flows through the cooler while the engine is running? I hope no more explanation is needed there.

BTW, your weak-*** attempt at calling me chicken-little is totally bogus. I have modified more cars over the last 40 years than you rode in. Therefore, I have no misgivings at all about modding cars. I do speak out against misguided attempts at modding for the sake of changing something. Our cars do not need an extra oil cooler unless the power output or duty cycle are significantly upgraded. Even then, a thermostat makes sense. Of-course this does not apply to you.

 

I don't even have an aftermarket cooler on my car yet and my oil takes a long time to heat up. My oem water temp is all the way up to normal for a few minutes before my oil temp gauge even starts to move from 140. If I had a cooler without a thermostat I bet it would take another 3-5 minutes past that.
