:D

One here.

Before you do anything, I will suggest you to get an oil temp gauge to see if you really need it.

You will need a larger oil cooler at hotter weather. The theory behind any heat exchanger is the same. Just think of it as a intercooler. The stock intercooler will work just fine on a cold day but it will not be sufficient on a hot day.

What are normal temps for an FD with one stock oil cooler in relatively warm (75-80) weather?

BTW, I also have some custom made AN to Metric fittings to adapt to the stock oil lines so you don't have to take off the AC pump and power steering pump to install the oil cooler. Power steering pump pulley is hard to take off if you don't have an impact gun. It's made of plastic so it crackes easily.

But if you want to replace all the lines with stainless braided ones, it can be done as well. I will offer both options.

I will be figuring out the pricing in a few days and get back to you guys.

Thanks.

if the oil cooler add on is more expensive than the single, i probably would go with one large single but would consider the add on unless it woudl be over 100-200$ difference.

You want to keep the oil temp below 220F. 180F-190F wil be ideal. No matter what the ambient temp is, you will need to keep the oil temp below 220F. When oil temp gets too high, oil starts to break down and its lubricating property will be affected.

oil lines
 

Just in case you are wondering what the custom AN to Metric adapter does, here is a pic of the stock oil line coming out of the engine.

Here is the custom fitting fitted on the stock oil line so you can bolt the AN hose fittings directly.

The same adapter is used on the driver side oil cooler so you can run stainless steel lines and AN hose fittings to it.

There is a trick to taking off the power steering pulley without an impact gun.

Take the power steering / AC belt off the pulleys. Then wrap the belt around the PS pulley, bending it over at the top and chucking it against itself (it will fold over because the belt has a lot more length, obviously). Take out all slack and attach the open end to the power steering 90 degree line fitting on the top of the pump and then loosen the bolt.

The belt tension will keep the PS pulley from moving. You want the fold in the belt to move towards the counter-clockwise direction so that loosening the bolt will tighten the belt's grip at the same time.

And don't forget to promptly remove all PS and A/C pumps, lines, and fittings permanently for a nice 50 lb weight savings. :) :) :)

I have to say, I like the 25 row driver side upgrade...since I track the car only a couple of times a year. Even then I try for the winter/spring/fall time frames here in GA. I think it would be enough for me. Only thing is the price:) If you make an option for adding a 25 row to the passenger side for touring models, would it be a little higher then just the driver side upgrade?

Also, I'd like to thank Chuck for the excellent customer service he's always given me. Answers e-mail inquiries same day or next if I wrote him late at night. Thanks Chuck.
