Do you need to upgrade your oil cooler when going single??
I was recently looking at Rotary Extreme's site, www.rotaryextreme.com and I saw that he had made a custom oil cooler 2.25 times the size of his old stock one to help cool his HKS T51 turbo.. He said because that turbo is only oil cooled. Now I have a FD Touring like his, do I need to upgrade oil cooling when going single?? or are there any turbos to watch out for that specifically use only oil to cool it???

I think so
Adding a big oil cooler has a few benefits:
Better quality oil
Cooler engine
looks cool
The stock oil cooler is just too small for me. If you really want to find out, tap a oil temp gauge and see if you really need it. The oil temp should not exceed 120 C or 250 F I am just too lazy to do all that. I rather spend the money to know for sure my motor is safe.

Maybe people are actually driving thier cars on the street other than drag racing? I think if my engine has enough power, my car can run 8-9 sec without even having a oil cooler. 8-9 sec of running will not heat up oil that fast right? How about track racing? 20 min of 6000-8000 rpm abuse is a lot differnt than a 8-9 sec run. I really think he should just tap a oil temp gauge to determine if he actually needs to upgrade his oil cooler or not. Just saying people run 8-9 sec 1/4 mile does not convince me that the single stock oil cooler is good enough for all kinds of driving or racing.

I am going single over the winter, so I wanted to know if it is something that I should look at doing for any turbocharger, or just if I was running a T51, which I won't be. I am going with a "bigger"turbo though. I am still kinda thinking what turbo, but I am going to pretty much "make my own kit"... I see both points of greg and rotaryextreme, I was just wondering who else had done it. Rotaryextreme if you are still reading, how much again did it cost you to fabricate yours??? I don't have ton of dough because of spending the money on the conversion and motor, etc.. But it is something that I might need to look into if I ever decide to take the car in for a day at the office, or a couple days.... Having the freedom to drive it on long drives would be nice, and traffic can be a bitch... and I would rather safeguard instead of blowing something.

hmm....did you read my post?
hey yo. did you really read my posts? I said you should get a oil temp gauge so you can determine if you really need it or not. This is the 3rd time I say it and I am not going to say it again. Guessing work is just not good. Actually measure= it to get the hard data is the way to go. I am excused cuz I am lazy and I have spare money to spend. How much it costs?
oil cooler: $250
lines: $100
fittings: $200
brackets: $50
thermo stat: $100

WTF?? LOL Ok, you are right I should determine the temps from the temps you told me to find out if I need to upgrade the oil cooler or not. Especially since I realized that it is alot of labor and parts. As I said the car is not totally single yet, but whenever I get it put back together I will put a temp gauge on it. Thanks

I have an Earl's oil cooler on mine. This is a single large oil cooler that works great. This setup will cool better than the dual setup from the R1 and has less of an oil pressure drop.
The Earl's oil cooler is also C H E A P !!!
I highly recommend it - it works great! Cooling the oil is paramount!

For those of you thinking about getting an upgrade oil cooler such as the Earl's or Mocal, make sure you use the thermostat. The stock motor runs at a very high oil pressure. If you do not use a thermostat, the oil cooler is going to burst open. Yes, it happened to my friend so I know. Don't try to save the $100. When it bursts, you will have a lot of oil sending toward your front wheel. The next thing you will find is that you are drifting like the crazy Japanse road racers.
