i recently got my car backed from the shop and they said i need to replace my oil pump. its a 92 LS and so far ive heard both the water pump and oil pump sucks ass on the LS motor. so i was wondering, should i replace it with a different Bseries pump? like a GSR pump or something.. and if i did that would i need a new timing belt? or should i just replace the part with the identical pump? or should i get an aftermarket pump? and if i did that, any companies recommended? thanks a lot in advance.. btw, which would cost most and less?
A VTEC oil pump will work and because the oil pump is timed off the crank not the belt you do not need a different timing belt. The LS water pump is fine if you aren't spinning past 7200 RPM.
