I'm piecing together an ls-t and figure i'll replace my stockand old water and oil pump.
i heard i can use an ITR water and oil pump on an ls w/ no problem.. this true?
next question, if that's true, can i still use a stock ls timing belt?
Thanks in advance for any help

THanks

 

I'm pretty sure you have to match the timing belt to the water pump being used. The LS and GSR/ITR water pumps have a different amount of teeth (19 vs. 22).

ls and gsr/itr belts are the same

 

B16a is also the same for the oil & water pump, incase it is easier to go to honda then acura.

 

GSR/R timing belts have 1 more tooth than an LS. You match the belt to the water pump.

so does the b16 have the same # of teeth as the gsr/r or as the ls?

I know for sure that Meziere who makes a B-series electric water pump kit offers a model with 19 teeth for LS motors and one with 22 teeth for DOHC VTEC motors. Like I said before, you have to match the water pump to the timing belt being used. Also, B16 water pumps and oil pumps are the same as other DOHC VTEC B-series water and oil pumps.

 

whatever w/pump u use u have to use same t/belt EXECPT!! the b16 b/c the block is shorter thus t/belt is not as long,, b18 blocks r taller..... easy way to do it gsr everthing oil pump dont matter u could use any but i use vtec { gsr } 4 better oil flow.

Hell ya thanks alot for your help

Just a recap...
All B series vtec water pumps and oil pumps are the same and have the same # number of teeth (22) and you choose the timing belt based on the water pump. the exception being if you have a b16 water pump, then you use a gsr/r timing belt, due to the b16 having a shorter block.
