ok i know this has been gone over a million times so i dont need any fuckface remarks just knowlegable ones thanks. ok i currently have a 99 civic si just about stock only a few bolt ons. but this is where it starts i have an aem v2 cold air intake. it wasnt secured well enough and it got a hole rubbed in it so it was sucking dirt and **** off the road. i think it went a few months like this. i found this out about 8 months ago. i havent had any problems untill about 5 months ago she started smoking like a bitch it uses a quart every 500mi. now 2 weeks ago vtec just up and quit on me i replaced the selinoid and pressure switch but it still wont work i hooked it up to my snapon diagnostic tool and ran all the tests the pressure switch isnt turnign off. so to sum it all up i think i dont have enough oil pressure getting to the head to activate vtec and if i take her to 8000 it throws a code vtec system malfunction.... so i been workin like ****** to fix it and nothin seems to help now im pndering the idea of pullin the b16 out this winter and building a ls vtec. my idea is to bore it to the max sleeve it and run high comp pistons new rods rings valve springs ....etc i would like to get some ideas from anyone who has done this build on exactly what parts i should buy i do not want to booost this i want it to be all motor. or if you have an idea about my lil problem that would help me out too thanks

You can find info here, here, or here.

Next time before you start off by saying <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 99civicsib16a2 &raquo;</TD></TR><TR><TD CLASS="quote">ok i know this has been gone over a million times so i dont need any fuckface remarks just knowlegable ones thanks.</TD></TR></TABLE>, why don't you search. It took me all of 5 seconds to click search and type in LS VTEC.

And as far as your problem, have you replaced your oil pump? I doubt after all the crap that's gotten in there, that the oil pump would fix it, but who knows. Perhaps if you try changing the oil a few times as well as cleaning the vtec screen, this may help to cleanse the motor the dirt.

-Shane

 

i chage my oil every 3000mi im a truck mechanic i know all about the importance of changing oil and **** like that. i fixed the hole as soon as i found it it was like 8 months ago so im pretty sure the motor is clean now. yes i have had the vtec selinoid body or whatever the expletive you wanna call it off about 5 times this last week the screen was clean. i also drained the oil checked for metal none found. i filled the crank back up with ATF and ran it till it got hot then dumped it hoping maybe a passage was blocked or somethign and the ATF would flush it out. i filled it back up with oil and changed the filter still nothin it kinda sounds like primaries are workign but deff. no secondaries. and i havent changed the oil pump. it weird vtec was workign just fine the night b4 and i got in the next day and had nothing. ps: the oil press light isnt on inside either?? i seen somwheres mentioned that a coolant temp sen may be at fault for this too or is that not neither here nor there???

 

Just because the oil pressure light isn't on doesn't mean that there is enough oil pressure for vtec, or enough to not ruin the bearings. Trust me, I am experiencing this right now. I installed an oil pressure gauge, and my pressure gets up to 50 psi MAX. VTEC is in-and-out, but my oil pressure light is not on. The light only comes on when as my manual states, the oil pressure is "dangerously low." Also, it takes 57 psi to fully engage vtec.

So, I am in the process of replacing my oil pump since I know my vtec solenoid is good. Just saying that it COULD be the pump.

-Shane

 

1. What are you talking about primaries and secondaries for?

2. About the coolant temp. problem, I know that if your car is not warmed to N.O.T., vtec will not engage, so this could be a problem.

-Shane

 

sorry about how i started this too its just how some of these guys rag on people its wrong not everyone knows a honda inside and out. i just started playing with em 2 years ago. b4 that i couldnt tell ya the first thing about a honda. i was strickly a chevy guy i knew a small block like the back of my hand but now im trying to get more info on hondas. its just stupid to rag on someone for lack of knowlege

 

i was talking about primaries and secodaries because maybe it will help if someone knew what was goin on in depth. i said that it sounds like the primaries or what ever you wanna call it at 4500rpms it sounds like that parts workin just fine. but at 5500 the secondaries do not work at all!!! i was thinkin maybe it takes more oil pressure to make the seondaries work or somethign

 

I am the opposite of you. I have had my experiences with different cars, but I REALLY got into it with my Civic. Now I own a '99 Sierra as well, and I am anxious to start doing stuff to that. I mean I've had the thing for over a year-and-a-half.

The reason I was asking about primaries and secondaries is because if you are talking about the intake mani, yours is a single stage runner, not dual.

-Shane

 

nah i was talking about the cams and all that. its a b16a2 dohc vtec engine... i was talkign about the points in which the different stages of vtec kick in 4500 primaries 5500 secondaries right?????

That would be on a gsr, the b16 will only have the engaugement at 5500.

I still don't think that the GSR has 2 different engagement points for each butterfly.

-Shane

 

im pretty sure your wrong about that cause if you were right then y in the hell would there be 3 cam lobes ???? normal mid high and y would the gsr cams work on a b16 head doesnt make no sense to meee?????

yeah it does

just build up a oem bottom end and get your head freshened up and put it all back together

 

wtf are you talking about butterflies??? like the butterfly in the throttle body?? im lost

No.

-Shane

 

do ya think ya might be able to explain what your talking about butterflies???

 

When you were talking about primaries and secondaries, the first thought that came into my head was the GSR intake manifold. It has primary and secondary butterflies (no I am not talking about the throttle body).

-Shane

 

ok well back to what i was talkgin about the b16 switches cam lobes at 4500 to a higher lift cam lobe and then again to an even higher lift lobe at 5500 right ???

5600.

You my friend need to search. The B16 has a single-stage intake manifold. Upon reaching 5600, VTEC engages. Once. That's it.

However, on a B18C1(GSR), there is a dual-stage manifold. VTEC engages at 4800. Air flows through one stage of the manifold for low end go, until 6000 when the second stage, commonly referred to as secondaries or "butterflies" opens up for more top end pull.

GSR cams work in a B16 head because all B-Series DOHC VTEC cams do. There's more to it, but you can look for it yourself.

As for the cam lobes, look it up. I'm not explaining it to you.
