There are two types of water pump for the M20 engine and it is essential to get the correct one for your engine.
The pump for the high compression engine (as found in pre-facelift/metal bumbered E30s) has two outlets for hoses, whereas the pump for the low compression engine (as found in facelift/plastic bumpered E30s) only has one.
Both types of water pump are available from a number of different manufacturers and vary in quality. The better quality pumps have a metal impeller (rather than plastic), these are generally considered to be the ones to go for.
