oil coolers

are the TII and NA oil coolers all the same?

I'm pretty sure the are since both coolers look the same off of my t2 and gxl.

yea, if you wanna upgrade, you can try to find one or two FD oil cooler. they're much smaller, i dont know about efficienty tho, i'd need to make some test.
but i wanna build my own dry sump system, i'll check this out.
