im trying to get my 91' civic with a d16 z6 to v tec and im kinda new to the whole motor thing so im trying to learn a little but i want to know if i can convert it to have vtec. also if someone could help me find the parts that would be awesome
 
Well the z6 IS a vtec engine, so all you need is the right ECU and the proper wiring to make it work.
 
well id still need a vtec valve cover too wouldnt i. and the cam gears.
 
actually i feel really stupid right now
but i read the letters and numbers wrong
its just a zc but its still the d16
 
Is it the SOHC ZC or the DOHC?

DOHC cannot be made VTEC.
SOHC can.
 
ummm... i still dont really understand the vtec thing yet im used to american motors and my dad just knowing what we need lol how do i tell if its SOHC or DOHC

The valve cover is just a cover that goes over the top of the engine head. You need a lot more than just the valve cover to convert your motor to VTEC. You'll need an entire VTEC head, plus an ECU.
 
well i got the ecu. but im confused as to what i need to get to get this vtec thing going

Seriously?

Step 1.) Open your hood.

Step 2.) Look at your engine.

Step 3.) Answer this question:

Does it look like this?

Or does it look like this?

The top one is a SOHC. The bottom one is a DOHC.

Is that clear enough?

:slap:

I just told you the answer to your question in my previous post; to convert your car to VTEC, you need a complete VTEC head and an appropriate ECU!

You seem to be confused on what a valve cover is. The valve cover is just a metal piece that covers the valve train, it doesn't include any of the internal engine parts.

A motor has two halves. The block is the bottom half, it contains the pistons, rods, crank, etc. The head is the top half of the motor, it contains the valve train, cam shaft(s), etc. The head is where the intake and exhaust manifolds attach.

In order to convert your non-VTEC motor to VTEC, you need the entire head from a VTEC motor, not just the engine valve cover.

Please, go to Wikipedia or something and do some basic research on how an automobile engine works. If you were slightly more knowledgeable about typical engine layouts this would be a lot easier for you to understand...

ok well first of all i couldnt figure out what style motor i had because all it says is zc. nothing else. secondly i was confused about the hole head thing i didnt realize that vtec heads were different, i thought i could just get the cam shaft, gear and the ecu and call it good. thirdly i thought that the valve covers that say "vtec" on them were different somehow

the first picture is the motor i have.

and by the way im just learning this shit so give me a break man.
 
ok.. another question.. you say the top pic is what you have.. are the spark plugs in the same spot or are they on the bottom side of the valve cover
 
ok well first of all i couldnt figure out what style motor i had because all it says is zc. nothing else.
Yeah, all ZC motors, whether they're VTEC or not, single cam, dual cam, whatever, all they're gonna say is "ZC." So yeah, I guess it could be kind of confusing, but still, it's not that hard to tell the difference between a single cam and dual cam, obviously the valve cover is wider to account for the two camshafts in the DOHC motor pictured above.

secondly i was confused about the hole head thing i didnt realize that vtec heads were different, i thought i could just get the cam shaft, gear and the ecu and call it good.
Nope, you need the whole head. VTEC is in the valve train. Just putting in cams from a VTEC motor won't do it.

thirdly i thought that the valve covers that say "vtec" on them were different somehow
They are different...they say "VTEC" on them...

My point was that the valve cover is just a cover that goes on top of the engine. It has nothing to do with the cams or the valve train or VTEC or any of the motor's internals besides simply covering them up.

the first picture is the motor i have.

and by the way im just learning this shit so give me a break man.
Sorry if it was too harsh, but you just seemed like you were totally lost and not understanding anything at all, so I just wanted to lay it out very simply.

What you need to buy is a complete VTEC D-Series head, preferably with the intake and exhaust manifolds attached, plus the ECU for that motor. If you can afford it, I'd look into picking up an EX or Si transmission as well. The gear ratios will be narrower, which will help with acceleration and be better suited to the powerband of your motor once you get the VTEC head on there.

Hope that helps...
 
yeah basically i was lost. i read all this shit on wikipedia that just made me more confused. i couldnt really figure out what kind of engine i actually had because the engine only says zc because my old engine died so i had to go through all these papers to find the invoice. anyways i think its starting to go through my head now. i can get an ecu a friend of mine has one for vtec. and my civic is an ex model so that kinda helps.

another thing, do you think ill have to find some special stuff to convert it since my car is automatic?
 
If the ECU is from a manual transmission car that could be a problem. I know you can chip an automatic ECU for a manual transmission, so maybe you can do the reverse also. Otherwise, you'll probably need to find an automatic ECU or use a VTEC controller.

Other than the ECU issues you won't need to touch the actual transmission itself.
 
ok cool i figured id have to find a different ecu for an automatic. and wouldnt i need a vtec controller anyways?
 
If you want to be able to set your own VTEC engagement point then yes, you will need a controller. It isn't necessary to do it that way though. All you need is an ECU that's appropriate to your setup, like an automatic Civic EX ecu for example.
