Is anyone running an oil cooler with their On3 kit? I just bought an 89 Fox with their 76mm turbo kit installed, I'm looking to cool down the oil temps and also upgrade the drainback oil hose. I've been looking at oil cooler kits online but I don't know what size of fitting to get, like -10an or -08an, etc. On3 tells me the line is 1/8 inch internal diameter, how do I relate that to a "an" fitting size? Is there a kit to upgrade the kits oi drainback line?

the standard drain is 1/2 " ie 8an

i always run 10an ie 5/8

dont mess with the feed line, its like 4an but really should be 3an(depending on turbo)

and if you relocated the filter, thats 5/8 iirc, which i always toss the rubber hose, and use 8 an (the passages in the 5.0 block are not more then 1/2) and if you go bigger, then you can screw with the way the system pressurizes...
