B18B timing belt

[T34me]

If i want to run a GSR water pump on my LS motor, can i still use the LS timing belt?

[d16_turbo]

why not just use a ls water pump???

[T34me]

LS water pump=22 teeth, GSR=19 teeth which means at high RPMS, the LS is going to stop pushing water and start making bubbles, but with the gsr, it still continues to flow at a good rate

is there air in your coolant system? why would you be making bubbles

you must use the SAME TIMING BELT as the WATER PUMP you are using.
