RB25det. Oil filter relaction and Oil cooler, what is needed

[RHDskyline]

I bought an oil cooler off Zilvia for cheap. I was going to put it on my 240. Then I was going to put it on skyline and now I'm just not sure

Ill probably run a relocation on skyline so i can hook my oil pressure gauge up and oil pressure up. And of course to make oil changes easier

I'll probably run a oil cooler on my 240 with thermostat cause it's my drift car and it will see a little more abuse than skyline
