89 hatch swap stuff?
alright well, i got my check in the mail today for my totaled 92 eg sedan (that also does not run due to needing starter and battery), that being said i have found an 89 EF hatch for sale near me, i dont know much about it since the add was vague but it is an auto and has a "1996 JDM engine swap with 50k miles" i have no idea what motor it is, or if its true, but what i want to know is with my 92 eg laying around do i have all the **** needed to swap to a manual tranny? can i just use everything from my newer civic? oh btw it has a d15b7 with a 5 speed (ofcourse). the ECU, wiring harness, tranny, motor, clutch pedals, master cylinders, everything is there.
if thats not possible then ill just end up leaving the ef as an auto and repairing my eg, then probably selling both to get something better.
im hoping to get it later today, and then my plans also include getting the parts for my civic too

Re: 89 hatch swap stuff?
It is possible that the 89 has a newer motor. It is likely DPFI and has retained the old DPFI intake and exhaust which bolt right up to a newer D-series engine. Same goes with the auto trans - which would need to be from the 89 so their wouldn't be any ECU issues.
You can use your entire 92 setup EXCEPT for the wiring. You will need to convert the 89's engine harness to MPFI.
You will also need to convert to OBD1. This will require a couple connectors to be replaced and wires to be extended on the engine harness so the OBD1 components plug in. Really not even difficult. If you are really good with wiring, you can make your own jumper harness or cut your OBD0 ECU plugs off and solder on the OBD1 ECU plugs. Better yet, spend $100 or so and just buy an OBD0 to OBD1 jumper harness and be done fast.
Lastly, you need to address your transmission. If you plan to use your trans from the 92, then you need to convert the 89 to work the hydrolic clutch. There are several ways of going about this. Check in to the solutions from HASport and Hush.
