Well, I took a look a t your "stats" and it's an impressive list of parts. It looks like you have a good combination that should provide years of enjoyment. I was particularly impressed with you mileage figures. Is this a daily driver? What compression ratio and deck height are you running? This engine is not that big and the stock oil cooler should be adequate unless your compression ratio is too high and causing higher than normal head temps. I suggest that you check that CR and if it's higher than 7.5:1, bring it down. You will lose some HP but you won't have all that plumbing to do or that cutting of bumpers. The fact that you have a 5 speed should have no affect on your engine temps. I think that your 5th gear is a bit taller than stock and that might have you running a bit higher temps at speed. But you are also running tires that are not stock circumference, so that would also factor into the equation. It would not be time wasted if you spent a weekend driving around and measruing your engine temps and cyl head temps so you can see exactly where you are and have a baseline from which to base further changes. Also, measure the ambient temperature and humidity, as well as you elevation ( from sea level) and barometric pressure. This is how the pro's do it. Doug, I think that the stock cooling system is deliberately over built/engineered and can adequately handle much higher performance than stock provided that CR's are kept in check for a daily driver. This would not apply to those interested in competitive racing or unreliable daily transportation.

As for Doug, duhh, I didn't even think about the bumper! That would be a good idea though the bumper would get hot and providing air into it wouldn't be that difficult or an eye-sore. You are correct, though, I don't have my bumpers on and they won't be going on since I've had the fender dimples smoothed over. Thanks for the input!
