electric fan help

[zambizzi]

im looking for a proper sized electric fan that will cool a m20b25 running on a 4 cyl radiator (from an m40) i was told a for Taurus is a good electric fan to run but id rather just buy a new one and i need to know good specs thank you in advance to whoever helps me

why not run a proper m20 radiator and clutch fan?

You really need the M20B25 radiator. and the best choice for the fan would be the OE fan/clutch the engine was meant to have. But if you are determined to go with an electric fan you need a +2000CFM 16" fan and an 82C thermo switch controlling an add-in 30A relay.

He probably wants the built in expansion tank on the radiator. Cleans up the engine bay.

FYI, Jand3rson runs an M42 radiator with his M50 swap. He's got a 16" Spall fan. Check out his build thread for more info.
