Brad, Any good welder or machine shop can enlarge your oil pan. Depending how particular you are, you can simply have them cut the bottom out of your existing pan, bend some steel to fit between your now two halves, and reweld it together with the spacer in between to enlarge the sump. Or you can go get an oil pan from a salvage yard and they can make one large one out of two. It does indeed help the engine if you are going to adhere to the original 100 hour service interval on the engine oil. On my 310s without an enlarged pan, I change the oil at 50 hours instead of 100, but they all have the oil coolers to keep oil temp down. Since you don't the larger oil pan capacity will keep your oil temp within reason and allow you to maintain the 100 hour interval if you want. Of course, oil is cheap. Your oil pressure sounds normal. I would not be concerned about maintaining 25 lbs at operating temp. Remember that oil flow is more important than pressure. You only need enough pressure to ensure that oil is being pumped up to the turbo. If you want, however, you can increase the pressure in the main oil gallery by adding a small shim to the oil pressure regulating spring at the front, right hand side of the block about 3-4" below alternator mounting. Hope this helps and best regards, WFE
