Doing an LS/Vtec and I need an upgraded oil pump.

I already have a B16 oil pump, is it the same pump as a GS-R's oil pump ? Or should I definitely go with a GS-R for the LS/Vtec ?
Am I correct in that the B20 oil pump=GSR oil pump ?

Am also going turbo on the same motor.

 

B20BorZ/B18C/B18C5 are the same. Definately use the gsr pump. Also, if you use the vtec water pump, you'll need a B18C timing belt, B16A is too short. And if you use the non vtec waterpump, use the LS/B20 timing belt.

 

What about the B16a oil pump, is it same spec as other Vtec pumps ?

 

No

 

Damn, my hopes and aspirations of saving money just got shot down with a one syllabled word....

 

Is GSR and Type R oil pumps the same??

 

Yes

 

BTW, thanks for the replies !

 

Welcome

 

Hmm I was unaware of these differences. So I cannot put a "R" oil pump on my b16a block? I didnt know that there was a difference.. thanks for any help. The reason I was saying this is because I can get a Type R oil pump cheaper than any other honda oil pump.. saving money helps.

You can use the type R pump, and it'll flow more oil than the B16A. The external dimensions are the same. Any Bseries pump will fit any Bseries engine. The difference is in the gears and relief spring tension.

 

crap i wonder.. if i should start researching oil and water pumps...
looks like i might be upgrading my stock oil and water pump when i rebuild my sleeved engine ! with my new pistons and rods...

Helpful info:

B18B oil pump 53qpm
B18C oil pump 75 qpm

B16A water pump 140qpm
B17A water pump 140qpm

B18C water pump 148qpm

 

Thanks a bundle... I've been looking for those figures !

 

Nice going rondigs, great info thanks for sharing....hehehehe.
Guess you can handle this thread all by yourself now.
dont worry, I stole that from someone else too

 

True, I will keep an eye out for you. Thanks tho !
A couple of questions tho...

Why is is that the B16a, a vtec motor, would flow less fluid than the B18B water pump ? And with that, why would Honda make the GSR motor flow the same as the LS motor (water pump) ?

I went to a Honda dealer the other day and they told me that the B18B1, B18C1 and B20 oil pumps were all the same part number... I assumed this was true due to the source of the info.

Anyone ?

 

hold on I will get the rest of the info that goes with Rondigs flow numbers.

 

all pumps rated at 6000rpm - now it makes more sense, nest pas???
think about the redlines on the motors these pumps come off, the typeR still has 2500rpm left to increase flow numbers before the limits of the pump are met, the LS pump only has 800 rpm before the pump has problems keeping up.
high reving turbo needs the better flowing pump, as to the part numbers, might be a way to save money, there should still be a difference if you order part and engine code.

HAHAHAHA-RTYPE11 is offically "the man"
If he wasn't such an @$$ though. Im mean...

 

Thanks for the info thus far Rtype an Rondigs... this info is like drugs... it's everywhere in your society, but the one time you need it, you can't find it !

I am currently going with a B20 oil pump (same as GSR) and a B16 water pump on the turbo LSVT (B16a/B18a). Good choices ?
