How big should my oil cooler lines be?

Hi folks,

I'm in the process of picking out an oil cooler for my Z and need some advice. I had decided on a Setrab cooler with -8 lines and a 180 degree oil thermostat. I have a trusted friend that recommended - 10 lines instead of -8. I thought - 8 would be plenty, but he believes they will cause too much pressure loss. What are you all running?

 

Thanks

I believe this is correct. All my -8 fittings (fuel) use 3/8" pipe and my -10 (oil) fittings use 1/2" pipe fittings. Like TimZ said, -10 will work fine, and most remote coolers and filter fittings are 1/2" pipe. Short runs work fine with this. Long runs would probably need -12.

I used all -10 lines with 12" fittings when I plumbed my oil cooler set-up on my Turbo Corolla. What a project that was!

My ZXT has 3/8" right now and I am going to upgrade that soon, as the power goes up. Although right now, my oil temps are in the perfect zone.
