water pumps are the same. you just need an oil pump.you can use the b16/gsr oil pumps as they are the same as the type r.

pm me a list of what b16 stuff you have, i have a spare laying around that i may re-build.thanks.

ls water pumps are 20t and b16 gsrand type rs are 22t so you dont get air bubbles in high rpm i have the water pump gimme 20 buks and have it and as far as the oil pump goes ALL bseries pumps are the same thing just rebuild yours or get one for an ls it dont matter

[95egB16A]

well in that case ill just use the ones from my b16 lol. ppl on honda-tech are all like you need the ITR oil and water pump the b16 wont cut it. blahblahblah.

i have both the ls and b16 both water and oil pumps. so ill just take the ones out from my b16 and clean them up and put them in.

and what needs to be done with the ls block to accept the b16 head? i was gonna get the golden eagle rod ls vtec kit.....

[delsol860]

as far as the block nothing just the lsvtec kit and youll be set but for the head you have to tap and plug one port and take out a plug and put the oil line thiny in it... ill pm you the link that tells you have hold on

[95egB16A]

knock sensor? the green plug?? its on the back of the block right below oil filter like the knock sensor on my block.??anything.

http://floridahondacrew.com/diy-do-y...onversion.html b20 and ls are the same thing different bore but same shit when doing conversion here ya go this guys that made this knows his shit its the one i refered to

[delsol860]

dont need it if your going into a civic other wise the wire from under hood to under dash has to be ran which dave himself could do for you but knock senser isnt really needed

all b seriesw pumps are not the same get your facts straight

[delsol860]

oh yeah your right cause when you go to the auto parts store to buy a oil pump for a ls gs rs gsr b16 type r etc they have the same part number right... oh and the only diff is the crank positioning sensor which unless your going to be keeping it obd2 you dont need

[jrsc_b18c1_12psi]

rofl it depends on the year of the motor

Oil pump Hullabaloo.
While Rebulding my engine I did a comparison of the 91 b18a and the 92 b17 oil pumps. They were identical. In several Publications I read, I learned the "Pros" would boost up thier oil pressure by "shimming" a non-VTEC oil pump relief spring, or by swapping in a VTEC oilpump. Of course I had to ask the question "what is the difference?"

Well, with the unwitting help of the local ACURA $tealership, I have the answer.

The difference between the VTEC and NONVTEC oil pumps is a washer.

yep you read that right, a washer.

Newer non VTEC and VTEC


Older non-vtec


Here look at these two diagrams. notice the washer? (it's # 12) taking that out allows the hexhead plug to sit lower and compress the relief spring a little more. this results in a higher oil pressure before the plunger is lifted off the seat to bypass the oil. the "PRO" recommendation of shimming or use a washer on the end of the spring would compress it the same amount, giving the same result. the springs are IDENTICAL in all pumps.

This is not something you mess with normally, and was not covered at all in my HELMS. if it's in yours let me know.

So what do you non-vtec'ers do with this newfound knowledge?
if you need a "new" oil pump save yourself the money and rebuild your old one.
first take out your old oil pump. Get some loctite, a dental pick, a 10mm allen wrench, and a big screwdriver Buy both rotors and a relief spring. Remove the screws. they are loc-tited in but will break loose using firm steady pressure.

[delsol860]

ooooook so what if the "pro" put that washer in a obd2 oil pump would that be a plus or minus?????.... look now im askin the questions hahahahaha

It has been quoted many times before that vtec oil pumps flow more than nonvtec. According to these part numbers that I rounded up below, this may not always be the case.

Quote: Acura Dealership 1992-95 Integra VTEC Oil Pump
15100-PR3-024 PUMP ASSY., OIL

90-95 Integra LS Oil Pump
15100-PR4-A03 PUMP ASSY., OIL

96-01 Integra Oil Pump All Models
15100-P72-A01 PUMP ASSY., OIL
91308-PK1-003 O-RING (26.2x2.4)
11810-P72-A00 COVER, TIMING BELT

As you can see all 1996+ LS/GS/RS/LS/SE/GSR/ITR Integras come with the same oil pump. They got the same exact part number. Therefore upgrading a 1996+ LS oil pump to GSR/ITR oil pump will not be benefitial. No increase of flow will be made.

It seems like the only 3rd gen integras that got the less flowing oil pump is the 1994 and 1995 LS. I do not know how the 1992-1995 vtec oil pump compares to the 1996+, but I assume that they are quite similar.

So if you were thinking about getting a GSR/ITR oil pump for your LS, you may not need too depending on the year.
