Re: B16 water pump for CRVtec? (getgot2)
my b16 water pump was same part number as 92-3 gsr water pump, Heres a part number if you want to cross reference against whatever GSR one you plan on buying

read this thread!

Re: B16 water pump for CRVtec? (sirhatchback)
Just read the other thread which missed one important thing a non vtec belt wont be desinged to run at the high revs a vtec hybrid can so imo id go for a vtec type belt & pump!

but is this design feature of the 'VTEC' belts something that i havent been told about?
it is interesting that people tend to think that there are VTEC parts and non-VTEC parts.
to me there are Honda parts and there are Honda parts.
t..
PS what rpm are non-VTEC timing belts designed to run at MAX?

Re: B16 water pump for CRVtec? (Chad)
vtec has less teeth on the water pump over the non vtec....
did you not read the linked thread above?
ie this one: https://honda-tech.com/zerothread?id=240352
the b16 pump has 22 teeth, with a 7 blade impeller,
the b20 pump has 19 teeth, with a 7 blade impeller.
read the thread...

Re: B16 water pump for CRVtec? (Monty)
The b16 water pump is fine for the crvtec or you can even use the b20 pump itself.
In my oppiion teh gear for the gsr pump is bigger and so you need teh gsr belt since its longer. THe ls belt will not fit around the all the gears, since it is shorter. THat is why people tell others to buy which ever belt for that pump. THe gsr will fit around the ls pump but will have too much slack and not be tight enough to take the slack out. The big and small gear is due to physic like the tread been saying The bigger the gear the less revolution and work for the pump. my .02 I have been using the ls water pump for overa year on my lsvtec. Off topic the only difference is the oil pump!

Re: B16 water pump for CRVtec? (ill phil)
I thought that the GSR/Type R/ B20 had the same part # for oil pumps? Am I mistaken?
i hope that clears this up.

Not sure abt non-VTEC belts but I know mugen/spoon/jun etc use oem vtec belts to run 11krpm+ so I'd rather have one of then just in case!

Re: B16 water pump for CRVtec? (tinkerbell)
I read the other post. It doesn't talk about the flow rate that much. If the water is flowing too fast through the RAD it wont cool it. That is one of the reasons for a thermostat. It slowes down the flow of water. I think the b20 pump will flow too fast. You mingt have cooling problems.

as for the reason i have cooling problems....i have the b20 water pump on....and water is way to fast even with the thermo in!!

The crank pinion is 17 teeth, so for every rotation of the crank, there are 19/17 or 22/17 rotations of the water pump or 89% or 77% of a full impeller rotation.
As I said above, there is a perfectly good reason for having a slower spinning pump on a high revving engine. And a faster spinning pump on a lower revving engine.
So the coolant goes around at a speed that is, on average, unlikely to be too fast or too slow.
This is assuming that it is understood that coolant has an optimum flow rate within an engine/radiator system to ensure that the system does not overheat (recall a system without a thermostat? or a cooling fan?)
anyways,
So, the real point is that people swapping the 19-tooth pump for the 22-tooth pump because it is “better” without knowing WHY it is better…
It is only useful to ensure that the speed of coolant flow does not go PAST a certain optimum velocity.

(just thought id clarify so the other thread doesnt have to be read by anyone who finds this one when searching...)

Re: B16 water pump for CRVtec? (tinkerbell)
so, yeah, use the VTEC pump plus the B18C timing belt on the B20VTEC to ensure that proper cooling is maintained...
water pumps (regaurding b18a/b/c and b16b blocks), if you're running a b16a, b17a, b18a/b (p30 pump, or pr3/pr4 pump) you would have to run a ls (pr4 or p7j timing belt) because the gear size on the ls/b16/b17 water pump is the same diameter. If you decide to run a gsr/itr (p72 pump) then you'd have to use a p72 (gsr/itr) timing belt. The reason being is that the block height on those blocks are the same (on the b16b, b18a1/b1 and b18c/c1/5) and is 7mm higher than a b16a block.
oil pumps, ls has a pr3/4 pump (depending on year), b16/b17 have a diff one (p30 I belive), and gsr/itr both have the same part # (p72), I'll check tommorow @ work and find out if the crv has the p72 pump or if it uses a p30 pump.

Re: B16 water pump for CRVtec? (tinkerbell)
okay, i refute my previous statement, autostore gave me wrong part, i tried to fit it on a regular b16 and it still didnt fit
go figure

Re: B16 water pump for CRVtec? (Death Scythe)
i thought that the b17 oil pump flowed more than the gsr/itr
and most people agree that the gsr/itr/b20 pump are all the same (oil)
as far as the water pump goes i just think that tinkerbell is right. use the vtec one if your running vtec. most people just assume because it must flow more but i guess actually cause it flows less
