This has been on my list of things to do for awhile now and Thanks to Merc I recently aquired the Evenflow cooling mod for $100.00 BRAND NEW. I looked over the goods and researched the topic good and plenty and the more I looked at it the more I saw room for improvement. I mean come on even a heater line is 5/8" thick, this entire kit is 1/2" thick and this is suppose to cool 2 cylinder walls? So I searched and found some parts that will make this kit 5/8" from start to finish. I also don't like the idea of running a coolant line that close to my throttle body and air intake so I'm gonna run the 5/8" hose down to the ABS controller across the frame and up to the rear firewall to the back of the cylinder connection. Here's a list of my parts, they all came from Napa
1.5" radiator hose splice with 5/8" nipple PN# 660-1742 $7.39
5/8" T connector PN# 660-1666 $10.49
5/8" 90 degree connector with 1/2"NPT threads PN 660-1702 $9.39
5/8 straight hose connector with 1/2" NPT thread (Lowes) $3.00
5/8" Napa heater hose .75 per ft X 9 ft
So the math is $140.00 for a cooling mod that will flow more and will not affect my IAT's for less than what a new kit costs from Evenflow. When I do the install I will also get around to finally installing my EMP water pump that I got a year ago. I'm sure my engine will be very happy when i'm done.
I just found some interesting info. If some are considering this mod Evenflow sells the adaptors with the 1/2" NPT thread for $45.00 each they come with the hold down and hardware. Two of these and the parts list above is all you will need to do this mod and it will be $10.00 cheaper than my kit. Hmmmmm... For $130.00 you get a better kit then they are selling for $155.00 Here's the link: http://www.evenflowcooling.com/products-2.html
