LS-Vtec timing belt

[CRXFreak]

ok so everything i have found sasys to use a gsr timing belt if you are using the b16 oil and water pumps so i bought a gsr timing belt and the shop told me it was still to small that it would be to tight and mess up my water pump. so should i tell them to just put the gsr belt on or what?

an excerpt from one of my favorite threads it may help you

Water pump installation. It would be to your advantage if you went out and purchased an OEM ITR/GSR (P72) water pump. But, if you use this water pump, you must also use the ITR/GSR (P72) timing belt. If you use the LS water pump, use the LS timing belt. The P72 water pump has 22 teeth as opposed to the 19 teeth on the LS pump. This means the GSR/ITR pump spins slower at higher RPM's, and vise versa. You may think this is bad, but it is good, because at those higher RPM's with an LS water pump, you will theoretically be spinning the pump so fast, that it doesn't even push water; it just creates bubbles (cavitation). Get it? Ok, so take your water pump now and spread a bead of RTV in the gasket groove, and then slip in the gasket. Bolt up the water pump and torque down to specs. Tighten them down in a criss-cross pattern as you would lug nuts. Torque to spec. Do not overtighten as you can warp the pump or crack it, possibly even strip the bolts. Bad.

my question is will it screw anything up to put the timing belt on?
since there is a difference between the 2 pumps.
