ok well i am building an ls vtec motor. and there is no acura dealer in town or anyone that can get me an gsr oil pump. my question is the b16 oil and water pump the same as the gsr?? i can get the b16 one from honda but i already have a gsr timing belt and almost everything else to finish my build. this is all thats holding me back lmk please

 

the write up for the ultimate lsv build says itr oil pump and vtec water pump j/w if i have to get the gsr since i bought the belt

The oil & water pumps on the vtecs are all the same.
Use the gsr timing belt because your block is 1.8 like the gsr.
The b16 belt would be too short.

 

i know i cant use the b16 belt i was just wondering about the pumps thx

 

This is not correct. OBD2 Integra oil pumps are all the same, 96-01 all models including ITR. But the OBD1 Integra oil pump is different. You can use an OBD2 pump on OBD1, but you have to modify the lower timing cover.

And the timing belt you use is determined by the water pump you use, NOT by what block or head you're using. B18B water pumps have 19 teeth, B18C1 pumps have 22 teeth. The B18C1 belt is longer as a result, and the B18C1 water pump spins slower, which pumps the water through better (less cavitation).

OP just order the parts you need online, like www.acuraautomotiveparts.org most likely it will be cheaper anyway.

To answer the question, 99-00 Si B16 water pumps were the same as 96-01 OBD2 Integra water pumps. OBD1 Integra and 93-95 del Sol VTEC water pumps had different part numbers, and I don't think they are interchangeable.

The 99-00 Si oil pump is also the same as 96-01 Integra oil pump. Same part numbers.

15100-P72-A01 OBD2 B16A/B18C1 oil pump
19200-P72-013 OBD2 B16A/B18C1 water pump

 

its going into an obd0 car my 90 DA so which pump would work without modifying my t/b cover???

 

you probably want the OBD1 oil pump.

 

what pump should i ask for from honda? just ask for an obd1 vtec b series oil and water pump?

 

nvm im goig with the 95 del sol vtec oil and water pump

 

are the ls oil pumps the same??
