Im planning out how to make a reliable oil system upgrade, I think im gonna go with a nice external air cooler as well as a filter. I have attached an image that shows the set up and the flow of oil through it. i have 3 questions.

1. is this diagram correct? that is should i cool it before i filter it? or does it matter?

2. If i were to tap into one of the lines for a line to the turbo would it be into line c?

3. would that tap be also a good place to put an oil temp/pressure sender being that that is the information about the oil as it is about to enter the turbo?

thanks

Pick up a B&M SuperCooler from Summit and an oil filter housing from a 90 DSM or older Mirage. Simple, cheap, and easy.

thanks but that answeres none of my questions

1 You want filtered and warm oil going through the coooler.
2 Supply oil to the turbo after filtration and cooler.
3 A sensor after filtration and cooling would be a good idea too.

Yeah, you would want to filter it first to keep from clogging up your cooler.

thanks i apretiate the answers

I would just like to add that the best thing to do is to get a '90 style oil filter housing which is a great part at a very reasonable price. This with a set of AN lines (preferably -10 AN) and a good cooler (Setrab ) will give you one of the best setup there is. You can also use an oil filter relocation kit , I have my filter on the passenger side between the tranny and the radiator and is easy to access it plus it is installed in a vertical position.
The built in thermostatic-bypass valve that the '90 stile housings have will provide oil to the engine without getting it through the cooler until it reaches higher temperature.

Greddy offers a direct bolt-on oil-cooler kit with braided lines, adapter, and everything, It's a bit expensive, but it's a nice piece.

I'm doing the same thing right now. Your diagram looks pretty good but backwards. Turn the flow arrow around and put an inline oil thermostat between the filter and the cooler. You only want to cool the oil when it needs it. A good idea would be to buy both, an oil relocator and cooler kit and mix and match, or try to find the seperate componets and make your own. I'm not to familiar with the 90' cooler adaptor, but I don't think it relocates your filter.
