250sxdet-Your statement makes sense and thanx for the suggestion. For now the car is great. I think a problem with rb swaps is the lack of space between the radiator and the front of the motor. There's no place for the hot air from the radiator fans to go. Even with the n1 pump good fans and Greddy radiator the car can run hot even if your just cruising around. The key is to get that hot air out so the radiator doesn't heat soak. This is why I added a frp vented hood. After the hood I noticed the inside of the car is cooler (car is fully gutted and acts like a oven). At stop lights I can see the hot air rising out the vents so the hood is working.

Also, what is your fans rated at (how much cfm's)?
