[zodpowercy]

As i changed my radiator of my s14a auto to a greddy 2 row i have to use an aftermarket oil cooler .
Can i use ANY oil cooler or do i have to use a transmission oil cooler with a large main pipeline ?

U can go to the junk yard and look around for one, as long it has the same inlet and outlets, and the bigger the better cool aswell, you dont want your trans to run hot
