i was wondering what all is needed to swap a JDM D15B VTEC motor out of a 93 civic Ex into a 91 EF civic Dx? plus the 93 motor has a hydro tranny and the EF is cable i think. thanx for any info

 

I know nothing about that swap except that there are adapter kits available to convert a cable chassis to hydro tranny, and there are engine mount kits readily available. There are also ODB0 to OBD1 adapter harnesses for the D15B ECU, but you also have to do some other wiring mods I believe.
Someone else can chime in for the rest.

 

You will not have to use a mount kit unless you want to use stiffer mounts like hasport. You can use the mounts that came with the EF. Also I am not sure if the car that you have it dual point injection or multi-point fuel injection. Multi-point fuel injection cars are easier to do swaps in because you will not have to do as much wiring. If you car is a dual point look on google for dual point to multi-point conversion for the wiring steps. the wiring is easier with the engine out of the car.

Good luck.

 

thanx for all the info
