I built an LS VTEC for my 96 Integra.

94 B18B Block
SIRII B16 Head

I re-used the oil pump from the 94 engine because it had under 100K on it. Will this pump support VTEC? If not, if I swap the pump over from my current 96 LS engine, will this pump provide enough pressure? I read that the 96+ Integra's had the same oil pumps across the board. With the exception of the Type-R I believe... So a 96 GSR pump would be the same as a 96 LS?

 

oil pump is the same, but you need vtec water pump

 

Hopefully your not just slaping on the the head and call it done.

 

No, but thank-you. I didn't just 'slap' the head on. Pistons, rods, ITB's, studs, re-worked head, are some of the things I've done to this engine. I used a GSR water pump as well thanks.

So the '94 Oil pump is the same as the '96? Can the '96 LS pump run VTEC? Can anyone else confirm this?

 

they are are same the only real different from oil pump is the crank sensor mount. the flow number will remain and wont change unless you are running a after market oil pump. just make sure you prime the oil pump when after install. please refer to the all motor Forum

 

I don't know much about the crank sensor, or how it's mounted. Can the engine run safely without it? I guess that depends on the ECU, correct? Otherwise, with the right ECU, I can eliminate it? Should I be running a crank sensor?

 

OBD1 oil pumps don't have the threads for a crankshaft position sensor to mount to. Also, the lower timing belt covers are different.
The pressures and volumes are pretty much the same. I remember coming across a thread where someone compared the oil pumps and the oil difference was a washer that increased oil pressure a bit.

why not? i have a friend on here who did it in a weekend and woops *** on h2b integras and gsr swapped ek's. do it right and you can "slap on together". used stock bolts and **** too, and still put down 163 whp. guy on the dyno was running as high as 8700 rpms. if its done with a good tune and people who know what they are doing and know the limits of the car/ parts then it can be slapped together.

 

...........

 

Try "slapping on" a vtec head on a STOCK LS or B20 block and SLAP ON some high lift cams, then tell me the outcome of your theory on "knowing the limits of the car/parts then it can be slapped together" is.

 

who said anything about some "high lift cams", sure wasn't me, or the op, or even you for that matter. where'd that come into play?

 

Lol i was thinkin the same thing

 

Yeah, you're right, I guess I was jumping the gun assuming that aftermarket cams would eventually be installed in combination with stock ls pistons which don't have deep valve reliefs.

 

90-95 Integra Oil Pump
15100-PR4-A03 (LS, GSR)

96-01 Integra Oil Pump
15100-P72-A01 (LS, GSR, ITR)

 

What do you say to those who say you shouldn't rev an LSVtec with stock rod bolts past 8k rpm's?
Cause I got a homeboy who is also running a B20Vtec, gsr head, s2s1 cams with stock rod bolts redlining at 8500 rpm daily.

 

wow ladies clam down this post isnt about egos the op had a good question that he needed help with he doesnt care about ur ego. So lets save it for the gen. dis. forums.

EDIT:
Yes all oil pumps are the same LS RS GSR all the same.

 

Thanks for the info to those who responded to my questions. However, noone has touched on my question about needing the crank sensor. Should I be running a crank sensor on this engine? I might use an OBDII Type-R ECU so I would need it right?

 

Yes if the ecu has a crank sensor then you will have to run one other wise you car will not run rite if at all. Ur computer uses this sensor to determin the rpms to make adjustment to timing and works with the camshaft sensor to monitor valve to piston relation and is a very important sensor used to engauge vtec. Most of the time when this sensor goes out the engine doesnt even start.
So if the ecu is pinned for a crank sensor ur ganna have to use one.

 

Great info. Didn't know half of that. Thanks very much. I'll be switching out the pumps so I can run a crank sensor.
