YANG PAKE MESIN HONDA ZC DOHC NGERUMPI DISINI YUUU..
Ini thread buat ente2 yg mesin mobilnya udh di swap ke mesin Honda seri ZC utk dipake Drag, sekedar kenceng buat harian atau emang bawaan mobilnya.. Daripada jadi anak tiri ngobrol di threadnya orang2 yg pake mesin seri B, F dan K mendingan kita ngerumpi disini aja ama sesama pencinta mesin ZC.. Mari kita berbagi info, tekhnik dan trik utk bikin mesin ZC kita makin yahud..
Sebelumnya gw perkenalkan mobil gw dlu..
Gw pake Honda Civic Si Gulf Spec karna gw tinggal di Qatar, ini foto2 mobil gw:
Mobil udah pernah dipake gaul beberapa bulan, sekarang saatnya mo gw korek abis buat time attack..
Ini sedikit info soal ZC dari berbagai sumber:
ZC similar to D16Y4, D16A8, D16Z6, D16A1, D16A3, D16A6, D16A9 and D16Z5 engines
A few D-series variants are labelled (Japanese: Honda ZC engine) (usually JDM), but they are not truly a different series.
There are both SOHC and DOHC ZC engines.
The non-VTEC SOHC ZC is similar to the D16A6 ('91 - '96) and D16Y4 ('96-2000) engine, but with more aggressive cam timing.
The SOHC VTEC ZC is similar to the D16Z6 ('91 - '96).
The DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.
Found in 1986-1991 (JDM) Civic and CR-X
Displacement : 1590 cmł
Bore and Stroke : 75 mm X 90 mm
1986-1987 Compression : 9.3:1 1988-1989 Compression : 9.5: 1
1986-1987 Power : 113 hp (84.3 kW, 115 ps) @ 6250 rpm; Torque : 99 ft·lbf (13.7 kg/m, 134 Nm) @ 5500rpm (US)
1988-1989 Power : 118 hp (88.0 kW, 120 ps) @ 6500 rpm; Torque : 103 ft·lbf (14.0 kg/m, 137 Nm) @ 5500rpm (US)
1988-1991 Power : 130 hp (96.9 kW, 132 ps) @ 6800 rpm; Torque : 106 ft·lbf (14.7 kg/m, 144 Nm) @ 5700 (JDM)
Valvetrain : DOHC
Piston Code 1986-'87 : PG6
Piston Code 1988-'89 : PM7
Fuel Control : OBD-0 MPFI
Euro Mk1 ('85-'87) 1.6 CRX's are fitted with an engine designated "ZC1" which is a higher spec 130 hp (96.9 kW, 132 ps) version of the D16A1. Which were later to be switched out with the D16A8 or B16A depending on which model.
1st Gen ZC Identified by: External coil, small distributor, dual butterfly TB, cam cover bolts on top, brown/gold cam cover. Large cam pulleys. +3cc PG6B pistons, non-pent roof combustion chamber. As a ZC it appeared in JDM AV Integra Si and JDM E-AT Civic/CR-X Si. Commonly produced at the time but now over 20 years old and getting harder to find. D-series version D16A1 '86-'87
2nd Gen ZC (rarest) Identified by: Internal coil, large distributor, single butterfly TB mounted on slight angle forward, bolts on top of cam cover, black cam cover, large cam pulleys. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a ZC appeared in JDM facelift AV bodied Integra Si did not appear in Civic or CR-X, rarest ZC only produced for less than one year. D-series version D16A1 '88-'89 (sometimes +7cc P29 pistons)
3rd Gen ZC Identified by: Internal coil, large distributor, single butterfly TB. Black cam cover. Cam cover bolts on the sides. Small cam pulleys. Inlet Manifold stamped PM7. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a ZC appeared in JDM EF3 civic and EF7 CR-X, did not appear in an Integra body. Most commonly produced ZC, manufactured in Japan from end of '87 through to early '91 D-series version D16A8/9 (Euro Civic Si) (sometimes +7cc P29 pistons)
4th Gen ZC Identified by: Internal coil. OBD1 EFi system (grey plug). No cam angle sensor on exhaust cam, now located in distributor. Rubber plug where cam angle sensor would mount. Black cam cover. No PGM-EFi plate on the inlet manifold, replaced with three ribs instead. P29 stamped on inlet manifold. MAP sensor on TB. +7cc PM7 pistons, pent roof combustion chamber. As a ZC only appeared in EG5 Civic bodies, no Integra or CRX received this engine. Reasonably common produced from '92 to '94. (20th Anniversary edition & Japanese car of the year) D-series version D16A8/9 (Euro & Australia Civic Si & NZ Civic Gti) (sometimes +7cc P29 pistons)
The ZC will bolt right in to the 88-91 CRX/CIVIC no fabricating or welding is needed
The swap can use your existing wiring harness if you have an SI, if you have a DX then minor modification is necessary.You can use the SI or DX transmissions, they both bolt up. You can also use the SI or DX flywheel.
The engine only adds about twenty-five pounds to the front of the car, so your steering and suspension should be the same. If you are still concerned about the added weight, move your battery to your trunk.

The S2000 OEM Filters will work also and are made by a reputable company in Japan that makes high performance oil filters, but you will pay more for them.
MY Suggestion…Get OEM Its only a couple bucks so why buy others when you can have a OEM filter for mostly the same price.

But any D-series 1.6L rods will work for upgrading.
88-89 Integra OEM
the std bore on a zc is 75mm so anything with that bore would work. a6,z6.ect. will work as long as it's a 75mm. but it depends on the compression you want to run.
There are many companies that offer ZC specific Pistons now, so Aftermarket is there.

is the same as the 88-91 CRX/CIVIC SI D16A6..... 55mm
b18b 58mm throttle body on a obd1 zc, it bolts right up but you need to port match the manifold to the throttle body
HKS makes cams for the ZC, here are the specs, 256 degrees intake and exhaust duration, 5.95mm Intake lift, 5.3 mm exhaust lift, they are ground from new billets.
The exhaust manifold for Greddy Turbo kit for the 92-95 Civic, was originally designed for the ZC. Greddy modified the casting tool for the D16 ports, so there is plenty of material to safely port it back out to ZC sized ports. However, the guys at greddy say don't bother until you are running over 7 psi.
" The scoop on the headers, is that while the bolt pattern for the Civic SOHC engines and the ZC engines are identical, the port pattern is not. The ZC engine has the ports shifted almost 3 mm (appx 1/8"). In real terms, this means that when you use the SOHC header, the ports do not align properly. The exiting exhaust gases literally run into one edge of the misaligned header flange. You can see this by holding the steel exhaust gasket from the ZC engine up to the DC header.
The easiest and best solution is to use the ZC gasket as a template and mark the misalignment. Using an air grinder, with a small stone "port" the header to match the ZC port configuration. While you're at it clean up the entry point of the header a little so that the whole port on the header is slightly larger than the ZC port. It is an old, but proven trick that the larger header port decreases the chance of exhaust gas reversing flow and re-entering the still open exhaust valves. It is better to have the port larger than to have them matched identical. Do not under any circumstances grind the port on the head to match the header though. This gives poor results."
adjustable cam gears
you can use B-series cam gears on the DOHC ZC, however, the marks for aligning the camshafts on the B-series gears are not the same as on the ZC gears - the B-series gears have 16 teeth between the teeth with the marks, on both the top and bottom of the gear - the ZC gears have 15 teeth between the teeth with the marks on the top side of the gear and 17 teeth between the teeth with marks on the bottom side of the gear - to use the B-series gears on the ZC, the mark on the left side of the gear for the intake cam is o.k., but the mark on the right side of the gear for the exhaust cam is one tooth off - you need to scribe a new mark on the next tooth above the tooth with the mark for the B-series and use that new mark for lining up the camshafts - here is where the new mark goes:
ZC Swap Links
links are from fourth Gen Hatch all these wright ups are made by that dude.. ive used them and know they work. he has alot of good tips aswell.
3G ZC Swap
You need an 87 Integra parts to run an 87 F.I. ZC motor:
tranny (waayyy better than a 87 ZC tranny (longer gearing))
hub & spindle assembly.
If you can get a Japanese ZC ECU get it!! I had it, it runs good at
idle. The 86-87 ECU tends to run a little rich at idle (stinky fumes
emmitted), the ZC ECU fixes that
& runs a bit smoother (way less fumes).
89 Integra valve seals DO FIT a ZC
almost all Integras have the same size valve stems dia. approx 6.6mm. My Helm book for 89 Integra confirms this, it says 6.56mm-6.52mm. My other Helm book for the 91 Civic says that the SOHC engines have 5.46mm-5.42mm valve stems.
I removed my exhaust manifold (again) and stuck a pair of dividers in the port to get a measurement. I did not use the most exact method because my dividers had straight legs instead of the ones where the tips curve in (wouldn't fit in the port). I then measured them with my calipers and got 6.5mm! I would say that that is pretty close.
I also got to thinking, if it was thought that the Teg had the 5.5mm valves, somebody would have noticed that when the valve seals were being installed. I'm sure that the machine shop would have given me a call to let me know that I got the wrong seals, that is quite a bit of slop for a "seal". So after all this, the 89 Teg valve seals DO fit a ZC.
4 speed 88-91
5 speed DX 88-91
5 speed Si 88-91
5 speed ZC 88-91
ZC Pressure Plate:-----1989 Civic DX
ZC Clutch Disk:-----1989 Civic DX
the 89 DX and the 89,90,91 CRX use the same size shaft and same number of splines on the
transmission. The 89 DX clutch disk and pressure plate is smaller in diameter by about one inch than the CRX Si. Although the flywheel is the same diameter on both. As long as you stay with one or the other it should work fine.
I know these have been asked before, and I know they will be asked again,
but here are a few ZC tranny questions.
Q-1.) For axles, I use the ZC halfshafts, 90-93 teg axles, and the 90-93
axles fit on all the 4G hubs?
Q-2.) Which clutch, preassure plate, and flywheel do I need? 90-91?
Q-3.) Does Quaife make a limited slip that would fit the ZC tranny? Are
the diffs in the ZC the same as in the other 4G's?
A-1) A better choice of axle would be two 88-91 Civic/CRX DX/Si right
hand axles with 90-93 Integra inner joints. If you have a CRX HF or
Civic Standard model a custom job is called for. OR you can use 88-91 DXSi knuckles and hubs and make your life simpler.
A-2) The clutch should match the year of the transmission you have, 88
if it is an 88 and your choice of 89 or 90-91 if the transmission is
89 or later.
A-3) Yes they do, I have one, it is not available through Autotech
If the tranny is an 89 or later you may use a 90 91 clutch, pressure
plate and flywheel.

Mobil gw sendiri pake ZC generasi ke 4..
Sekarang buat yg pake ZC juga ayo dong pada tunjukin mobilnya atau hasil korekannya..
Gw juga lagi ngebangun Civic ZC buat time attack nih, dan gw lagi pusing nyari camshaft racing en intake karbu 4 barrel utk mesin ZC. Klo ada yg mau jual kabarin gw ya..
Wah, kek na di indo mesin kek gini jarang de bos.
Cm kurang tau jg y.
Mesin ne lumayan bos setau sy temen da ikut drag pake mesin ne jg 201m dapet 10 kecil di body crx.
Mesin na std ja, cm gnti koil luar.
Sukses bos ma project na.
wah zc dohc jarang bgt di indo..
btw genio 2 doors yg di film the fast and furious 1 yg bajak trailer itu zc dohc yak? seinget gw genio 2 doors di amrik sering dibuat drag race baik resmi ato ilegal dan klo ga salah pake zc dohc
Iya, banyak yg dipake balap liar.. Soalnya klo yg VTEC sayang klo VTECnya mesti dibunuh buat bisa pake cam derajat tinggi.. Tapi gw liat di modcom ada juga beberapa orang yg pake mesin ini deh, terutama yg main gaya JDM..
biasanya di indo zc yg sohc pak bukan yg dohc..TS nya kan bahas zc dohc

Dlu temen ada pake di genio, gw bengong waktu dia bilang baru gnti mesin honda 1600 DOHC NON VTEC!
Eh baru tau gw zc non vtec ada yg DOHC ehehehe
Waltu itu spec mesin cuma modif stage 1.
Tenaganya lumayan kok
Emg si kayaknya di indo nyari barang2 kompetisinya dikit
Tp kalo diluar smestinya banyak.
Si bos gk coba cari info2 disana?
Soalnya gw nonton di utube ada lumayan bnyk mbl2 honda disana yg kenceng2.
di amerika sampe ada kelas khusus zc hehe
pernah gw liat mtv ada cewe' dibedah rumahnya sama cowo2 tuh cowo' kaget liat tuh cewe punya genio or eg9 2 doors zc engine buat balap liar dsana
ni mesin asoy lho....pernah nyoba zc dohc gen 2 std abis pake karbu maestro buat harian enak bgt....klo gak salah yg jd inceran tuch gearbox nya seri L3 klo g salah,mainin d final 4.4 dah sip...tp y itu spare part racing nya susah beeng....org2 mending pake SOHC or malah naik Bseries skalian....kir2 bgtu....
final gear civic jdm kan 4.4
kpn hari ada yg jual di bursa 2.5 jt klo ga salah
19th June 2010, 15:43

Emang langka yg pake nih mesin ya padahal klo dimodif pake 4 barrel nih mesin bisa lebih kenceng dari ZC SOHC.. Skrg di Indo ngetrendnya pada ganti B series atau ganti head ZC sohc yg vtec, padahal diluar negeri pembalap liarnya justru pada matiin VTECnya pake camshaft VTEC killer.. Suaranya jadi kyak mobil2 drag di sentul http://www.youtube.com/watch?v=dHVCyj4GqPo makanya daripada gw pake B series mubazir VTECnya mendingan ZC DOHC kan..
22nd June 2010, 05:37
fastest zc di amrik zc non vtec 10 sec @quarter mile..cm apa itu dohc ato ga gw ga tau..up up
22nd June 2010, 06:02
23rd June 2010, 14:18
for mas seto
mas,skrg ada di indonesia ngga? saya mau banyak cerita2 nih tentang ZC DOHC saya ..
asli saya lg pusing cari barang3nya skrg,jujur emang kenceng ni mesin untuk ukurang di kelas std .. karena stdnya aja saya udah bisa masuk HP:122hp torque: 150 mesin cuma di ganti header,modul bahan bakar,delco city,dan setting2 klep sedikit.. kemaren sempet tes di senayan sama yg kelas 14 - 15 sec alhamdulillah bisa dapet mengejar diatasnya tp yg saya bingung cari cam,per klep,sama as roda nya,karena saya pasang mesin ini di mobil nissan sunny kotak tahun '92,dan sekarang lagi bermasalah dengan as roda nya..
thx tolong bantu yah mas seto
24th June 2010, 08:01
Wih sadis juga ya hp:122, torsi 150 bisa ngudak mbl 14sec di atasnya...gw aja ke asaf kadang suka bawa zc sohc vtec klo disuruh lawan mbl yg waktunya kira2 udh 14dtk sih ampun2an.
