Does any other LSx water pump (housing) fit the LS4?
« on: Jun 28, 2015, 05:27 AM »
hi all
in my build I expect to have excess space on the front of the engine; or at least a bit more than the average...
I don't have an LS4 water pump aluminum body/housing. I am wondering if I can bolt on another LSx water pump housing or if I run into other problems...?
Has anyone ever looked at this (yes, I know, ... "why...."?)
Just asking in case.

Thanks in advance

Its possible, the only issue is the LS4 is made to be about an inch smaller from front to back of the engine to allow clearance for the FWD platform. I'm sure you'd run into serpentine belt fitment issues. The coolant manifold on the front of the engine houses this water pump. Kind of a junk design in my opinion, but its all they could think of.
