if you have a JDM DOHC ZC it will bolt right in and you need to make a minor wiring change at the distributor - if the engine is a D16A1 from 86-89 Integra, it is not a ZC and will not bolt right in and really is not worth the hassle to try and use it - we have been swapping DOHC ZCs into these cars for the last 8 years and have done around 3 dozen of them - what do you need to know?to who ever that has completed a ZC swap into a CRX Si 91'. i need all the info. in doing the swap and was told that it bolts right in? I was planning at first just to swap in a 92'si hatch motor, but decided to buy the ZC from one of my boy. he said i need to do some mods with the wiring. What parts, wiring info., and what problems i might get into??please if ya completed this swap, and your car is running fine. Please help a brother out and so therefore i can get this over with. Currently i'm trying to finish my first swap of an type r motor into my 92'si hatch, hey almost done. any info. regarding the ZC would be a great help. thanks ya......
the D15B7 transmission uses a hydraulic actuated clutch where the 88-91 cars use a cable actuated clutch - to use the D15B7 transmission in the 88-91 cars you would have to fabricate mounts for it - you would have to either install the hydraulic clutch system in the car or somehow convert the transmission to use a cable clutch - the D-series transmissions have a different bolt pattern (where they bolt to the engine) than the CG transmissions, used in the 86-89 Integras - you can get most of the bolts for the D-series transmission into the D16A1 block, but not all of them - the starter on the D16A1 mounts different than on the other D-series engines - it bolts to the transmission only where the other D-series starters have one bolt to the transmission and one bolt thru the transmission into the block - the D16A1 engine block does not have a hole for the long starter attaching bolt that goes into the block, so you end up with one bolt holding the starter on - the driver's side engine mount on the D16A1 is on the front (toward the radiator) of the engine and not on the end like other D-series engines - you need to fabricate a new mount in order to bolt the engine into the carfor 90 crx
do you think for the d16a1????
d15b7 tranny and flywheel fit to the d16a1 and i know ill have to change the dizzy and t/b but i think thats it and out ppl argue that it will not go in no matter what i do unless its make my own mounts
