Civic EG

ok so next week i will be putting in a motor for my brother he has a 94 ej2 and the current motor is a d15b7 and he is buying a motor from a 00 civic i know it's a d16 but i dont know the rest of the code and i was wondering if i will be able to just drop the motor right in and hook everthing up and it will run fine or if i will need anything for it?

i cant say i know everything but ull need another ecu and the wiring may need to be cut and redone, i only know this from when my mate got one in his it was a D15b7 to a D16z6, so if ur putting vtec and mpfi in then ull need a diff ecu and wiring loom plus gearbox.

i dont know if the new motor is v-tech but the i wuz hoping that i didnt have to mess wit the wiring harness cuz i hate anything electrical but all well...

A different engine will need a ECU for it. Also it will require a wiring loom if it is a VTEC. Non VTEC uses a different loom

find out if it is d16y7(dx, lx), d16y8 (ex), or d16y5 (hx)
that will make a big difference in what you need to do.

You'll need a OBD2 conversion harness and the appropriate ECU.

If you have charcoal canisters in your country then you'll need an OBD2 charcoal canister.

You'll need the throttle cable from an OBD2 Civic or you'll need to fabricate a throttle cable bracket.

You'll have to extend the IAT sensor wires over from the intake manifold to the intake tube. If you have an aftermarket intake you'll have to mount the IAT in it.

I'm pretty sure you can re-use the old engine's distributor on the new head so that it plugs into your OBD1 distributor wiring. If not you can buy a distributor conversion harness.


It's always better to swap the same OBD generation engine as the chassis.

dam thanx for the info guys idk if i wanna go through all that jus to drop in another single cam but it's wutever it will be a learning experience..
