Aluminum oil pans / external coolers?

[John Coffey]

Its obvious you want a baffled pan when you have no real need for it.  Here's the best available option.  Part number 139-1006.

Used to Autocross Z cars in Mod class way back in the mid 70's.  Goodyear 21x 8 x13 soft compound slicks. No G meters back then, but car handled like a slot car. Had to be pulling well over 1 G. No oiling issues ever with stock oil pan.

Also ran a D-Production Z car ( ICSCC ) in the late 70's on Goodyear slicks. Had a very expensive Aviad oil pan ( 7 qts, fully baffled, windage tray ). Pan leaked like a sieve because it was built improperly ( Twisted ) . Replaced it with a stock 240Z oil pan and ran the car for two years with Zero oiling issues.  Won quite a few races with that car. Stock pan is well designed and more than adequate for Streetuse,  Autocross and Track days  IMHO. FWIW.

I have an oil cooler on my car (it came with it), and my only complaint is that it works too well! It didn't come with a temperature valve, so under normal driving (it's mostly a daily driver) I had a hard time getting the oil above 160 degrees. I found simple solution, though, which was to just block it off with a piece of insulation, and now the oil runs at the same temp as the engine (about 180).

On the track or when I really push the car, it keeps the oil around 200-210, which I think is OK.

I do have a larger 3-row radiator, but no special oil pan. The car did come with a racing pan like the one at dpracing, but it had clearance issues with the steering rack and the tranny, so I took it off. (It could have been modified it to fit better, but I didn't think it was worth the trouble considering how I drive the car most days.)

If I had to do it over again or lived somewhere where it was warmer (I'm in MN after all), I'd consider the oil cooler, but I'd definitely get the temperature valve...something like this one: http://www.thezstore.com/page/TZS/PROD/17-8057.
