So it seems that nobody thinks an A15 needs a high volume oil pump. You guys might be right. I like to over do things.

On my E16 engine with this same oil cooler I had 50+ lbs of oil pressure all the time using the stock oil pump. I also add something to the system, I put a hydraulic system check valve right at the oil pump outlet, before it goes to the oil filer and thermal reulator, so the system can't drain back into the oil pan. It makes a neat noise at idle too. Am i crazy?
