Last fall I installed the Koyo "N" pass radiator and it works very well with my FMIC.
My previous all AL rad was 1.75" thick and single pass. This one is 2.25" thick and triple pass. It does the job very well.
Mazmart now offers an improve FD water pump for low $300s. It has an improved impellor blade that does not cavitate.
