zc/d16z6 rebuild help

[94gay-lude]

i need to know the following please...

is there a zc tranny rebuild kit? if so where can i get one?
is there a d16z6 head rebuild kit?
what kind of clutch would be best for a set up like that? what brand?
and does the d16 head bolt right up to the zc?

[ILIKETODRIVE]

First of all, which ZC? SOHC non-VTEC, SOHC VTEC, or DOHC?

Now, on to the easy stuff...

No need for a "rebuild kit" for the trans. Crack it open, inspect and replace what needs replacing and call it a day. I can tell you that you'll want to replace the ISB seal, both axles seals, the ISB, both diff bearings. Pay careful attention to the shift forks, they can break like twigs. Don't worry about the syncros, they pretty much never fail in D-Series trans.

Clutch? NA or boosted? If NA, any Stage 1 clutch kit is more than enough. If boosted, any 6-puck clutch kit should suffice.

Bolting a Z6 head onto a ZC block? Again, which ZC? SOHC non-VTEC, SOHC VTEC, or DOHC?

my bad, sohc 1.6 non vtec

[ILIKETODRIVE]

Okiedokie, that makes things betteR.

The head bolts up without a problem. It's just like doing a Z6 head on an A6 block. You just need to pull the oil jet that is between #2 and #3 near the back of the block so that the head gets enough oil for VTEC to work.

hmm theres a stock sohc vtec?

[lunchb0xxx]

stock sohc vtec ZC sorrry

[gcboy90]

no no such thing as a VTEC ZC... im pretty sure....

VTEC SOHC would be a D16A6 i believe

but instead of rebuilding... you could buy all my shit? DOHC ZC built??? i cant get it to run in this fuckin car... but it does fire, i got it to turn over today... but it didnt last long..... but thats this stupid car's problem

so i will sell you everything... ECU, tranny, motor, axles... and mounts if you want them... 800 man

[ILIKETODRIVE]

Wrong and wrong. Want pics to prove it?

SOHC ZC non-VTEC = D16A6 (what I have)
SOHC ZC VTEC = D16Z6 (what a buddy of mine has)

Both have a slightly different cam compared to their USDM counterpart. The non-VTEC ZC's had a 4-2-1 header instead of the lame 4-1 of the A6. The carb'd non-VTEC ZC's are, well, carb'd. The MPFI non-VTEC ZC's have a weaksauce IM and TB.

A6 ~ 108hp, SOHC ZC non-VTEC ~ 118hp
Z6 ~ 125hp, SOHC ZC VTEC ~ 130hp

ya was the d16z6 in any obd0 or all odb1? i wanna toss one in my hatch if i dont sell it... if i do. ill be needing some of the SOHC masters advice : )

[ILIKETODRIVE]

Z6 came in 92-95 Civic Si's and EX's and 93-95 Del Sol Si's.

You can easily convert your hatch to run the Z6 properly. Jumper harness, P28 ECU, dizzy jumper, full Z6 longblock. Then, re-use your OBD-0 injectors and leave the resistor box wired in.

[lunchb0xxx]

ya i had onefst91hatch tell me he would help with the wiring.. i just need to find someone with a complete swap, how much do those run?

[ILIKETODRIVE]

If you can get just the complete longblock, shouldn't be more than $400. Full swaps with trans, which you can't use, are around $500-$600.

You could also call H-Motors Online and ask them about the SOHC ZC VTEC. They don't list it but they have them. I believe the longblocks are around $600.

Simon knows his D's thats for sure

Are you possibly the D series version of me?

I wonder

Heed his words!

[lunchb0xxx]

hahah ya... what do you think about this engine in an ef? i know you sport the non vtec

[ILIKETODRIVE]

With the right gearing (aka - ZC trans with 4.25 Si FD) and I/H/E, you should hit high 14's.

[lunchb0xxx]

damn... wish my dual cam zc tranny would bolt up. bell housings are diff arent they? and whats i/h/e?

[lunchb0xxx]

ohh intake header/ exhaust... im an idiot

[lunchb0xxx]

so does hasport make shift linkage? or could i use my dual cam zc shit?

[ILIKETODRIVE]

DOHC ZC trans does bolt up. D16A1 trans from USDM 86-89 Integra does not.

All D 88-91 linkage is the same.

If you have a DOHC ZC trans with midshaft and the LS axles, USE IT. You'll need to drill/tap holes in almost any SOHC block to run it but it's worth it. OR, you can crack it open, have someone like Tage swap in an Si 1st/2nd/5th and Si diff/FD and have a killer trans that is almost identical to a hydro GSR gearing-wise.

[lunchb0xxx]

ya? i knew the zc was a pretty decent trans. i know the 3rd and 4th are bomb, my rpm's hardly drop when i shift into them... but my syncro went out on my 3rd!! : (( so while its open maybe ill try to git some si gears... those are gunna be a bitch to find huh?

[ILIKETODRIVE]

Si gears are the easy ones to find, you already have the difficult ones. :)

Also, it's probably not your syncro that's bad. Heck, I'd bet it isn't. D-Series syncro's don't really go out without beating on them on purpose. It's either a really bad rear mount causing major engine rock when you shift or your 3-4 shift fork is going bad.

Finding an Si isn't necessary, it would just make things a bit more fun with the 4.25 FD and things a bit more lax on the highway with the .771 5th compared to the ZC .878 5th.

Where did I say that? Quote me plz.

If you're talking NA, you're going to need A LOT of compression to make those numbers. Like more than 13:1 compression.

[gcboy90]

well i have a DOHC ZC swap... the ZC is built up too... so lmk
