Not doing a build, just a rebuild. I had some cam bearing get damaged. I'm reusing the stock crank, rods, and pistons. Put new crank and rod bearings in (Cosworth race bearings). I then sent the heads off to get machined and got the delta 148 grind. The head shop did an angle valve job on my valves and decked the heads for me. So it's kind of a build but mostly just on the heads. I'll only be spinning it to the stock redline wich I believe is 6200.

Below is the difference between the 9mm pump and 10mm pump, should I fill my oil to the level of the 10mm to ensure I don't suck it dry at say 5900 rpm? Should I maybe try and find a WRX oil pan or would that even fit? With the design of the the oil pan and baffle plate don't think I would have to worry to much about churning up the oil.
