    I could be wrong but i think you need a 1st gen integra distributor. If you have a sensor on your exhaust camshaft then you need a 86-87 integra one, If theres no sensor on the exhaust camshalf you need a 88-89 one. Do some more homework on this though. The only zc's i have experience with are the ones that look like the d16a1 s. All dohc zc's use a d16a1 head gasket though. FYI

    Have you tried changing out the ignitor on the old original distirbutor yet??

    not quite correct - 86-87 Integras used a vacuum advance distributor and won't even come close to bolting onto the 88-91 JDM DOHC ZC - the distributor you need is from 88-89 Integra D16A1 - all 86-89 Integras have the cylinder sensor on the exhaust camshaft - not the same sensor, but in the same location

    the ZC in the top picture without the cylinder sensor on the exhaust camshaft is the 92-up OBD1 DOHC ZC which has the cylinder sensor in the distributor - the distributor for it is a TD43U which was only used on the OBD1 ZC - the rest that you have pictured all use the same distributor which is TD03U same as 88-89 Integra

    this is the 86-87 Integra D16A1 which uses the vacuum advance distributor

    this is the JDM 84-87 "browntop" DOHC ZC from the 84-87 JDM CRX/Civic Si which is pretty much like the 86-87 Integra

    this shows the difference between the 86-87 and 88-89 D16A1 heads where the distributor and cylinder sensor bolts on - the picture says crank angle sensor but that is not correct - it is the Cylinder sensor

    STFU how did the thread get jacked. We are trying to determine which zc he has to determine which distributor he needs. Damn I cant stand your kiddy post.

    The problem with this is the motors that are only released in cars that are in Japan make it difficult to source parts, half of the dinks in the part stores will say a z what. I just finished going through this, luckily I got to talk with a mechanic at Honda that actually was familiar with these motors. Otherwise sites like this are your best resort.

    You most likely need the distributer from the 88-89 integra . Look at your block just above your header it should tell you the year of the motor.

    i have been in touch with this guy on another forum - his problem was that he bought an Si car with the ZC swap already in it and whoever did the swap, changed the connector on the distributor to the round Si connector instead of swapping the right connector onto the harness - this caused the problem that the Integra distributor was no longer plug and play and in order to change distributors, he would need to change the connector - he decided to get the distributor jumper connector for Si to ZC from Rywire, like this:
