I was wondering if 96 and up B18 oil pumps are the same? I heard that they all flow the same rate. If not, then can i use a 94-95 GSR oil pump on my 96 b18b? I want to know b/c i am building a lsvtec and i currently have a b16 in my car (95 civic) now, but the 96 b18b i just picked up has the stock oil/water pumps and no lower timing belt cover.
If i use the 96 gsr water pump and timing belt, will a 95 gsr oil pump work? Or do all b-series oil pumps have the same sized/amount of teeth on the gear?
I am using a b18b block with an obd1 b16a head, do i have to use gsr/itr head studs or can i reuse my b16 ones?

 

you can use any b series oil pump, they dont have a gear, they gear goes on after that, on the crank. its a seperate peice.

You have to use the gsr/itr length studs because the deck height of the b16 is different than the 1.8's.

 

ok thanks.
Does anybody know about the flow rates? I've head all pumps from 96+ are the internally the same. But i've also head that all pumps 98+ are the same.

 

Don't use an LS oil pump, use a GSR (same as ITR pump)...

 

all 96-up b series oil pumps are the same. so it doesnt matter as long as its a 96-up pump.
