So, i have this project Eg and i live near SoKo (Engine Importers) i was looking into doing a ZC 1.6 SOHC Vtec (they do make em'), BUT come to find out the Dohc Zc and the Sohc Vtec 1.6 Zc are gonna be pretty much the same price... can any one point me in the right direction for any kind of instructions on swapping a Dx - Dohc Zc?
i would be thankful for any help!

Ive got one in a del sol. its a straight forward swap. HMOTORSONLINE.com has them, you have to call they arent listed on the web site. My advice to you is make sure you purchase the ECU that goes with it, and try and get the LSD tranny as well....Other than that its plug and play......Use your stock wiring harness, but your stock ECU isnt that great of an idea. Change the timing belt, use the one from a 90 prelude Si. CAm seals if you need them are the same as a del sol B16. Trust me the ECU is the key to making this swap worth it, without that ecu the engine sucks!!

i can use the stock Dx wiring harness? or am i better off with an Ex harness? i'm planing on running aP28 chipped w/ chrome, it's gonna be turbo'd! i was just gonna pick up the long block since i have a Z6 tranny already.

sorry to threadjack, but this question relates to u 2,

does the stock motor mounts for the EG/93-95 Del Sol engine mounts work on the DOHC ZC?

Dont forget to get the proper length axles... I think it's a mix/match on either side.

Dont mean to thread jack but I dont want to start another thread.

So from what I gather, the ZC swaps right in plug for plug into and EG correct? The one im using was OBD0 I was building it in my EF so that why Im keeping it and wanting to put it in my EG I have the mounts for the EG and OBD1 ZC diztributor. My question is regarding the IM, will an OBD0 one work as long as I use my CX injectors or are they too small? I have the firewall mounted map sensor as well. Will my stock P05 get the car running to driveable conditions? I will chip it with a P29 PROM as soon as I swap I just need to make sure the car will actually start with the stock P05. Ive got the si tranny as well so its pretty much all ready to go minus the manifold I just want to confirm everything first.

wow.. thers alot of confusing questions in here.. i just recently did the obd1 dohc zc swap in my 92 cx hatch.. if anybody has anyquestions feel free to pm me i will help out as much as possible.. im using the obd1 dohc zc hydr zc tranny with halfshaft.... the right computer to get would be the p29... they are very hard to find.. i got very lucky and bought mine from a guy on thezcr forums for 60 shipped.. its in excellent condition.. i was happy but you can chip anycomputer to the p29 specs.. id just get the cheapest one like the p05 cx computer since the p29 specs only use 1 wire o2 anyway...

the motor is a direct swap with an ex tranny.. use the axles for the car and use the dx wiring harness.. or the cx wiring harness would be better since u only need the 1 wire o2 sensor wire anyway.. it wont look like crap like mine.. i am using the ex harness.. (the only spare i had) so i have the vtec pressure switch sensor and solinoid plugs there.. and i have my 1 wire o2 soldered in with the 3 wires sitting there..kinda ghetto .. just use teh cx harness

the dohc and sohc zc's are all plug and play. Look at your O2 sensor and the map sensor. If the map is on the fire wall get an engine with it on the fire wall'if your o2 is 1 wire get an engine with one wire. try to get the ecu or chip it to what ever you need to to turbo it. there are seveal zc's to look for the 1st gen brown top(88 89)integra, the 2nd black top(88 91)obd0,and the 3rd black top obd1 (92 95). the sohc is for the 88 to 95 civic. it has vtec or non vtec. All d series parts are interchangable so you oppsones are great. Just look a round. I have the obd1 dohc zc with a t25 turbo and i had no problem with the install. If you need any more help let me know

i had to make custom axles.. you can buy them from raxles.comi gues there kinda expensive... i bought 2 ride side axles for my car.. the civic 1 drivers side 94-01 integra axle and 1 passanger side 88-89 acura integra axle

its kinda a pain in the ass to make them if u dont know what ur doing.. if u live in cali somewhere near socal i can help you out.. but what u have to do is take the inner cups that go into the transmission off the integra axles and put them on the civic axles it takes me about 30 minutes to do it and put them on

if u want u can pm me and i will show u the pictrues actually i did a write up on how to make them search for it... how to put a zc tranny in 92-00 civic
