ok i was wondering about this, i have a d15b7 in my civic and its pretty up there in mileage, i was wondering what it would take to get this engine swapped with say a d16y8. i just wonder about the motor mounts mostly. i want to know if i can just drop this in or if i am going to have to buy some mounts to swap this engine in. also i want to know what difficulties i am looking at doing ths swap. i dont have the money for b16 or b18c but i know from my last 2 ex's that the d16y8 is the way to go for sohc. thanks for the help:jump3:

The EX 5th gen D-series motor was the D16Z6, it's an OBD-I motor. You're 5th gen hatch is OBD-I also. You won't need new mounts, it'll bolt right it. You'll need the D-series Vtec motor and the OBD-I sohc vtec ECU. As I said, any 92-95 EX or SI hatch has the D16Z6, and they are OBD-I. If you opt to use the Y8, you'd most likely want to try and use the Z6 ecu if you can, as wiring up a OBD-IIa ecu to your OBD-I car is a headache. All D-series trannys are interchangable, so you shouldn't need a new one unless you want one. If you have an auto tranny, make sure to use an auto ecu, if you have a manual tranny, make sure to use a manual ecu.

ok i see that the mini me swap is also an option but i am unsure of the advantages and disadvantages of it. i see all kinds of stuff to do it and everything on ebay. my questions are how hard is this swap? if i did this swap would i be ordering parts for a d16 or for a d15b7 like i already have. i dont mean to sound stupid about this but i need to explore everything cause my car is up there in mileage and i want to see if it would just be easier to swap the engine rather than attempt the mini me swap. another question i know obd1 and obd 2 has something to do with exhaust cause they are anal here in n.c. over this stuff. what are the differences in the 2. thanks dude

i also found the d15b vtec swap also, is this just as easy to swap as the d16z6 or will it be more complicatehttp://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33615&item=7935312186&rd=1 thats what i am looking at.

JDM D15B VTEC seems pretty good. At first when I got it, I was disappointed, since my old engine was a PH16 (local 1600 non-VTEC one here in the Philipines). But after reading up on it, I found it to be good. Maybe I just convinced myself it's good, hehe! But it should do fine for you as well.
