Ok, here are pics of the oil cooler. Thoughts from the group appreciated, especially in comparison to a stock Mazda oil cooler....
Initial impressions:
1) Nicely packed (85$ shipped!)
2) Has some weight to it, nice TIG welds
3) They clearly pressure tested it for leaks. Has two stoppers with rubber seals, when opened pressurized gas escaped...
Did I mention dirt cheap?
Compared to a stock Mazda oil cooler, there is no thermostat to remove
The oil inlet/outlet base are HUGE. You could tap this for a 1 inch fitting if you wanted
Current fitting seems to be some type of 1/2 inch to 0.6inch straight fitting. Tried a 1/2 NPT plumbing would go in... My guess, its a 1/2 inch or 12mm regular fitting...
Now, you can easily tap the fitting to 3/4 inch, or weld on a 3/4 inch AN fitting... Tapping it would seem way easier, as long as you can make sure you can get all the shrapnel out...
The question I have, is how much oil can the core flow? Is this comparable to a mazda oil cooler?
