I took the blown d15b7 out of the car.

1.
Went to swap the harness and found that the sensor behind the intake doesn't have the same plug, the one with the black cap, upper back drivers side corner of engine. What do I do?

2.
I knew the transmission was cable instead of hydraulic, but why if the d16z6's a 92-96 engine?

3.
The distributor From the d15b7 of course matches the pinout of the harness (the dizzy from the d16z6 has round white plugs instead of the grey square ones i have on the 92 harness) But I can't get the dizzy to line up it's bolts! Ideas?

4.
I noticed the fuel rail is different on both of them, in fact the whole intake is, what gives?

5.
the d16z6 vtech solenoid has a 1 wire peice and a 2 wire connector. Neither of them have a home on the 92 harness. Where do these go?

Thanks

Update:

More confused now then ever, neither of these distributors seem to line up. any help at all would be appreciated

Sounds like you got a Z6 someone had swapped into an EF and converted to OBD0. Stock Z6 trannys are hydraulic. All the electrical problems you are having are due to someone using OBD0 components. A stock Z6 will drop in and plug up just fine, the only work needed is to wire in vtec (on a '92 civic you can simply use an EX/Si engine harness and not have to wire anything, due to vtec being prewired to the shock tower plugs.)

Whoa, the tranny is cable? I'm about to get this swap and thought it was hydraulic.

So the stock dizzy on my 92 d15b won't work right? How do I tell if the other dizzy i have is vtech? It's got odb0 connectors spliced into it which i can prolly undo with a wiring diagram.


Since i'm having plug problems with my intake manifold, does that mean it's obd0 too? Should I/could I swap my d15b manifold back over?

94EG8

They are hydraulic, the tranny the OP has was not originally mated to a Z6

The only difference between a Vtec and non Vtec distributor is the mounting flange, everything else is identical (on OBD2 D-series distributors theres no difference at all)

Most likely, though its hard to say for sure without pics. If its OBD0 it will most likely say PGMFI across the top, OBD1 units say nothing

You can, but its more restrictive than a real Z6 manifold.

So it WILL fit? How do i know if it's lined up correctly? Can I do what I've done in the picture below?

Check out pics below and let me know which one I should go with? I can always split the wires on the connector that doesn't fit. (where's a pinout?)


Also, look at my thermostat housing conundrum and the extra connector on the pic below and let me know what you guys think?

10$ paypal 'd to however gets me running tonight. (This engine hoist is expensive to rent.)

What's mainly holding me up right now.

--Need to know about the green connector on the vtec solenoid vs the water pump connector on the d15b...

--Need to know how in the world to get either of these dizzy's hooked up correctly...



Here's a pic of the dizzy the guy said would work with the engine he gave me. It's been drilled out in a couple of places and lines up all wierd. i don't know which way it should be facing or anything. That's my biggest concern right now.

94EG8

you can use one bolt to hold the distributor on, The better solution would be to buy an OBD1 D-series vtec/vtec-e distributor. (all you really need is the bare case, everything from the D15B7 distributor can be swapped in)

Reuse the D15B7 IM. or again, ideally pick up a Z6/JDM D15B Vtec IM

I'm pretty sure I can see the thermoswitch on the thermost housing in the Z6 peeking out from behind the wiring harness, otherwise someone swapped an OBD0 thermost housing onto the block (OBD0 engines have the thermoswitch on the back of the block, and either way you need one, otherwise the rad fan will not turn on) The green plug is for the vtec pressure switch, you will need to run the wiring for it and the vtec solenoid (in pic as where does this cable go??)

willpower102

No, it must be an odb0 thermostat housing bc that's just a watter pipe you see. So I'll swap those.

So A total of 3 wires need to be run manually correct? I can do that no problem. Where exactly do they terminate? (someone mentioned before my 92si harness having a vtech connector somewhere, like maybe the part attatched to the bay?)

I'd love to pick up the correct manifold, but the car has to be outta here saturday. I also need to get a test fire out of it tonight before I continue on to swap the tranny and install my brand new clutch, so I need to kinda of have it "as is" Until I get it back to my place where i can put on the correct dizzy and do the computer mod or order another one.

94EG8

The distributor the guy told you would work is a butchered OBD0 unit. It wont work with an OBD1 ECU, even if you rewired it, there are either more or fewer teeth on the toothed wheels inside for the CYP/CKP/TDC sensors. As I said earlier the D15B7 distributor will work, using one bolt, its just not ideal.

94EG8

Correct.

All '92 only civics have vtec prewired to the passenger side shock tower plugs, see pic below. All you have to do is run two wires from there to the vtec pressure switch and vtec solenoid, the third wire is a ground coming from the vtec pressure switch, you can ground it anywhere on the engine.

Unseen Racer

change the plug from your d15b7 to the IM from the z6

as mentioned before, the z6 tranny was changed to a cable tranny.
just get a hydrop D series tranny

you can either buy a new z6 distributor or line up the top bolt.
many people run with the top bolt only on for easy tuning

the z6 has a bigger IM and bigger TB. the d15b7 has smalled TB and IM.

drop the motor in and head out to a junkyard tomorrow.


ITS VTEC!!!!!
not VTECH!

Vtec= variable valve timing and lift electronic control
Vtec=Phone

get a 92-95 Ex or Si Harness.
your b7 didnt come with VTEC so it has no plug for it

willpower102

So which bolt is the top bolt? The d15b dizzy only allows one position for the bolt to go all the way through, but then the housing is pointing with the round section at 90 degrees straight up. Is this correct?? What direction should the round section face? Every photo i see has it facing about 210 degrees as per below? I've got the engine suspended in the car and would like to try a test fire but this is the last thing I'm lacking.
