Engine Oil Cooler

What is the good and the bad with having the stock Engine Oil Cooler. I recently picked up a GN with the Oil Cooler taken out. The motor has a lot of work, just curious why the engine builder would not have use it.

Who knows why people don't use them. I put a Earls external cooler on mine, some use the stock cooler and other's use nothing. I guess its all a matter of opinions. I would use one because your sending your oil through a turbo that can reach temps of 1600F. IMO its a no brainer to run a cooler (same goes for the trans). I guess for the hardcore racer adding a cooler is adding weight, I did it for peice of mind.

Yeah that's what i was thinking. I have an extra universal oil cooler adapter, just need the lines to hook up to the radiator. I have herd those lines are pretty pricey, has anyone found a cheaper way? I was going to use two 5/8 rubber hoses like the ones used in the universal kits, I just need the fittings for the radiator. I would figure they are metric thread just not sure of the size.

It certainly won't hurt anything running a cooler but most ditch it because it helps clean up the engine bay, removes lines that may potentially leak, etc. I was always told if you constantly run your car hard on the street or in hot climates, run a cooler. Race cars may not run them because they only run a short 1/4 pass and are done. Heck, some race cars don't run engine coolant!

Most ditch it due to losing a motor and having bearing debris in it. Then take into account, a lot of GN's are not driven daily or even for long distances at a time so the oil doesn't get really hot in the first place.

Oil coolers help with keeping oil at a certain viscosity, what guys like myself due when we ditch the cooler is run a thicker oil to make up for the lack of a cooler. It's not the same but I don't drive my GN for longer than a half hour usually anyways.

Oil doesn't go through a 1600 degree turbo unless it's being pumped through the exhaust housing. The housing radiates heat into the center section, but not enough to create a 1600 degree environment that the oil touches.
