^^^ hi power racing has built a b20vtec a while ago for their track car, give them a call.
but i will stilll be safe to use B16 water pump and oil pump with B18C timing belt?
i heard that all B water and oil pumps have the same teeth is this true?

Yeah its fine
Any VTEC items with the longer B18 VTEC belt is all good
Thanks guys, this topic is great, keep all the good info comming.
Just got myself a new engine for my car but was looking at a b20b8/vtec build..
yes, VTEC with VTEC & non-VTEC with non-VTEC, the answer is that the VTEC water pump has 22 tooths, and the non-VTEC has only 19 tooths.
but B16A timing belt is useless for frankies, as the B16A block is 7mm shorter than a B18C or B18/B20
no that is false. see above re. water pumps.Quote:

plus Honda oil pumps dont have teeth.
so is it bad 2 use a 19 toothed water pump?
i have read that it is, since it has less teeth it would spin at a faster rate. but this isnt good, as it would be spinning too fast to actually pump the coolant.
ahhh ic, ive just had my b20 rebuilt and the builder wasnt sure which water pump 2 use, im sure he said he used the 19 toothed pump. should i replace it with the 22 toothed pump?
I think the question is, how hard are you going to rev?
The 19T water pump will cavitate at higher RPMs.
why did you rebuild your motor.? wasnt it that 999automotive b20?
If a B18CR spins to 8700rpm with a 22 tooth pump, a 19 tooth pump will be spinning at the same rate at 7500rpm. Are the impellers the same? No idea.
@chr1s only revs to 8500rpm.
@gsi-psi yeh it was, (they f*cked me over though with pricing). head was f*cked and then had 2 replace some valves and then found out the block had a slight crack in it between cyl 2 & 3.. costing me 10k (crazy i know)
hmmm in your next build maybe just use a stock b20 crank, B18CR crank more wear and tear in the upper rpms,
