I just did this swap,,,
I wanted to put on a different FAN,,,to keep the car cooler,,,
Got a fan from "Eric" here on the board ( he sells them,,and a few members run them )
The FAN is awesome,,,moves a TON of air,,,,

The issue of clearance came up with my old Moroso,,belt driven water pump set up....( which i didnt care for too much anyways ),,,belt from the WP motor ran off the front snout of the water pump

I got a Meizere pump,,,and swapped it in. Fit with no problem,,, MUCH more clearance,,,and the car runs way cooler,,,
I wired the fan and pump on seperate switch's,,,,last fall,,i had to shut the fan OFF,,,cause the car was running too "cool" ( which is a nice problem to have ),,,

There is a weight difference,,,,dont recall how much,,,,
Not sure i saw ANY change is HP going from the Moroso to the Meizere,,,but hard to say,,,,
