i have a b18b1 that i will be building to handle more power. I have heard that you can run a type r water pump and timing belt on the non vtec's. I am just not sure because Import Sports Performance, Denver, Colorado told me that they have never heard of doing that. Can someone please correct me if this is possible or not. Thanks

s.cha

usually people switch the oil and waterpump for ls/crvtec but when they do that they also have to use a gsr/type r timing belt

Davidls

this is for a straight non vtec. ive heard of people using type r water pump and timing belt on a non vtec, just seeing if thats true

philafelman

whats wrong with the b18b water pump and t-belt....theyre not exactly "performance items".

Davidls

the type r is better for shifting at higher rpms

philafelman

how? if you dont mind me asking.

all obd2 b series oil pumps are the same and the vtec water pumps flow more and yes you can use them on a non vtec. i have a gsr water pump and t-belt on mine now. just match the timing belt to the water pump you get. just be aware, not sure about type r, but the b16 head is shorter than the ls head so if you use that water pump then that t-belt will be a snug fit to the ls but it will still work.

on my ls i have a b18c oil pump, water pump, timing belt. oem honda

Davidls

ok thanks guys just making sure because i already have the type r pump and timing belt

silverdcteg

get the matching water pump also

no problem good luck on your build!

Let's see where to start...

How about here: http://www.team-integra.net/forum/di...g+Common+Topic

To sum up the quoted post, the VTEC H2O pump is LESS efficient than the Non-VTEC pump. The reason is that due to the high rpm operation of VTEC engines, the LS pump would be spinning so fast that it would just cavitate and not move any coolant. The VTEC pump actually spins slower to help prevent this. If you are using a VTEC pump on a non-VTEC engine, you are operating with less cooling efficiency. Not recommended.

Type R heads are from the same casting as B16 heads.

And yes all B-series oil pumps are internally IDENTICAL.

Remember: just because it says "Type R" or "VTEC" doesn't make it better for your engine.

And don't forget to search. This is a common topic. Not sure why you decided to post this in the FI forum though???

Good luck!

^^^ I agree with kchungb17a. The LS waterpump will keep the motor cooler and be better for the LS, I have not heard of anyone using a Type R waterpump and timing belt, however I have heard of people using the Gsr waterpumps and timing belts, so I am thinking they should be the same, but if you are keeping the LS, then you should just keep the LS waterpump and timing belt.

kchungb17a

Type R H2O pump/T-belt = GSR (B18C1) H2O pump/T-belt.

Basically, if your LS block has an LS head, use an LS H2O pump/T-belt.

Davidls

i just heard the type r pump and belt were better. i think i remember turbo_ls saying it

Davidls

i posted in the FI thread because my motor is boosted

kchungb17a

David - Better is a relative term. It may have been better for turbo_ls's setup but who knows what that entailed?

Better is only better if it makes YOUR engine run BETTER.

Davidls

i think im gonna play it safe and get get the ls pump and belt. this is kinda making me want to make a build thread, so you guys can see what im doing

turbo ls knows his stuff so your just misunderstanding him. the ONLY reason to run what your saying is if you rev your LS motor higher then factory limit. If you plan on revving the motor past 6500rpm then YES running a VTEC water pump (with t-belt) will in fact perform much greater then a non Vtec water pump. When revving high the non-vtec water pump will just froth your coolant into a freaking milkshake.

Also most run a vtec oil pump as well when revving past stock ls limit as the pressure relief is much higher. running a non-vtec oil pump with high lift cams and high revs will actually eat your rocker arm cups due to the lack of oil. so figure out what your going to do with the motor and match togther what you need.

"Find" something called "Honda Acura EPS", or compare part #'s at places like acuraoemparts.com and hondapartsdeals.com

You'll be amazed at the parts binning Honda did. For instance a GS-R's (P72) complete vtec solenoid consists of a sohc vtec's solenoid/connector (p08), and actually carries a b16's part designation (p30).


So many things will interchange. But you have to make sure they do, and only do so if you have to. Honda isn't GM, they do things for a reason...

i remember him saying it too which is why i said it. he seems like he really knows his **** and helps everyone on here. but this guy couldnt just fix the mis information without puttin in his own just cause it says vtec comment.... lol thanks buddy

kchungb17a

Sorry, didn't mean to come off sounding like a dick. Damn drunk posts.

I'm not saying that turbo_ls doesn't know his ****. I was going to add that if you have an LS spinning in the 8k range, a vtec water pump/belt would be better. But then I wondered why you would do that b/c then you would probably have poor idle quality, so I decided to leave that out. But if that's your thing, more power to you.

My main concern was trying to correct the statement that the VTEC H2O pump was more efficient than the LS pump when all else equal, it is not.

Davidls

so if im staying in the 7k range because my head wont be built for awhile, ill just be on a built block should i still do the vtec water pump and timing belt now because eventually the head will be built

Bond

Just please re-read my post. All the info you need on this topic is in it. Been there done that, just read it over again and I know you'll find your answer
