LS VTEC
I know theres alot of threads about it but my question is whyh type r oil pump and type r waterpump. one guy said its the timing gear. the cam gear got different number of teeth than an ls.. i don't really get why type r oil pump and waterpump.. i know for the belt it has to be gsr or type r due to the fact the belt is gonna be to small. help please
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. Do not overtighten as you can warp the pump or crack it, possibly even strip the bolts. Bad......

SO BECAUSE OF NUMBER OF TEETH ON THE GEARS U USE GSR OIL PUMP, AND WATERPUMP?
SO IF A GEAR HAS MORE TEETH DOESN'T IT TAKE LONGER TO SPIN AS OPPOSE TO A GEAR WITH LESS TEETH?
SO GSR OIL PUMP HAS HOW MANY TEETH COMPARED TO LS OIL PUMP?

if thats the case what about the cam gear and crank gear.. for every 1 revolution of the crank the cam turns twice.. well does it remain the same when u add a vtec head or what? or the cam gear teeth are same as ls and ****

To my understanding, the cam gears are the same between these engines...actually someone correct me if I'm wrong, but I think they are the same between d and b-series...except for the fact that the D-series is just one.
Either the LS or the type r will work with your setup. I'd recommend the type r, because its obviously made to rev high. I think it flows a lot better also. There are no teeth, and there is no oil pump pulley. They are driven by the crankshaft.
i can do ls vtec and keep the everything the same? ls crank, ls oil pump, waterpump. if i use ls waterpump than i can use ls belt..
but if i use type r i need gsr belt to accommodate the more teeth the waterpump has and so the belt can fit right?

Correct...but I HIGHLY recommend using the GSR/Type R pumps. Especially if you plan on revving higher that 6.5-7k rpm, which is the RPM range that the VTEC head really makes the most power.
