H23 block
H23 head
H22 timing belt pulley on crank
H23 tentioner
H22 water pump

possible?

anyone? In case you are wondering why I want to use an H22 water pump on my H23 block, it is because the gear is larger, and therefore is under-driven a little bit.

 

Can you even bolt that water pump to the block? I didnt think so....

 

yes you can. a mechanic put an H23 water pump on my Ex-GF's H22 by mistake and it ran for a day or two until the belt jumped a tooth because it was too loose.

 

You could just use the H23 timing belt. Correct me if I'm wrong someone.

by this logic, the timing belts are not interchangable. I am wondering if the water pump is the only reason.

 

NO! do not do this its not gonna help its gonna hurt the car. Yes it bolts up I know this for a fact. But if you want to use a h22waterpump that badd your also gonna need h22 camgears and a crankgear to make the water pump work correctly and its not gonna do anything leave well enuff alone. And the h23 waterpump doinger hav the post sticking out of the pump so for you to not notice the difference in the pumps before you installed it hmm tiem for a new mechanic I would say

 

the timing belt pulley on the crank has the same part number...

 

guys ever looked at a h23 head and a h22 head?? the deck to middle of the camshaft is longer than the deck of the h23 dead to the middle of its cam.
the VTEC head stands taller.. has nothing to do with water pump.

 

Yeah I know the head stands taller. That wasnot the question he wanted to know which t-belt to use. you can use either belt as long as the crankgear camgears and water pump match.

 

the crank gear and cam gear have to match as far as i know. why would you want to under drive your cooling system? but as long as u had a matching bottom end and cam gears i think it should work.

 

the part numbers are not the same either sorry your wrong the part# for the h23 is 13621-PT2-003 and the h22 is 13621-P13-003

 

what are you asking or sayin?

 

Is that the part number for the water pump or crank gear?

The reason I want to use the H22 water pump is to underdrive it slightly, as i will be revving my H23 to H22 RPM's. ITR guys will trim the wheels on their water pump to provide less resistance at super-high RPM, I don't see why we can't do the same.

so far we have established that H22 and H23 cam gears are the same, but the gears are farther from the block... the water pumps are different, the tensioner is different, and my source shows the crank gear having the same part but you are saying it is not... right?

 

well then if the cam gears are the same but only higher up on a H22 block then if i were you i would use an h23 lower crank gear and an h23 timing belt. Becasue if the h23 cam gears are closer to the block then the timming belt will need to be shorter, and even if you use an h22 lower gear it along withthe tensioner might not take up the slack, and throw ur timing off. My take would be as long as the h23 and h22 waterpumps have the smae gear pattern you should be fine. but if they are different your gonna **** something up

 

simple, if using an H22 lower timing belt 21 tooth gear, and H22 42 tooth cam gears, then an H22 timing belt

if using an H23 lower 17 tooth gear, and 34 tooth cam gears, then an H23 belt

 

your cam gears, water pump, and crank gear have to be the same(h22 or h23) the belts are diffrent to fit the gears and everything. belive me. i bult a 23vtec and everthing is off a h22. the belt wont fit the teeth for the diffrent parts... but the water for sure fits the block.

 

thank you mt23vtecbb2! as i said the cams gear are not the same on the h22 as the h23 infact that h23 cam gears are the same as B series(integra,civic Si blah blah). anyways there is not need to rev your h23 past 68 unless you have that will make power up there do you? I have a dinan ECU for my only H23 and reved to 74 but times were actualyl slower shifting at 74 then at 68 because there is no power made there and drops over the power rage if anything i found best hiftingpoint right around 7K. but like i was sayin the cams gear, water pump, crank gear must be either all h23 or h22

 

for sure, i got a spoon chipped p13 9k readline but i will only push 8k max... full skunk,rev head goods. no point going past where the power stops

 

why the hell does the water pump matter??? it doesn't matter how many revolutions the water pump makes in corrolation to the timing
