Parts needed:
86-89 integra
-transmission (four out of five bolts line up on the 88-95 blocks, even the dowels line up. You will have to tap ((12x1.25)) the starter hole that normally goes through the tranny into the block because the hole is not lined up with the one on the block)
-front tranny mount
-clutch
-flywheel
-shift linkage
-Starter (drill out the left mounting hole (when looking at the back of the starter) to accommodate the larger 12x1.25 bolt)
-pressure plate
-intermediate shaft (the two bottom holes will line up with the area on the block which you must tap ((10x1.25)) the top hole will NOT. You can cut and weld it so it does line up. Make sure you align the shaft while the tranny is on the motor so you can get the angle PERFECT.)
-axels
-knuckles and/or hubs
-engine wiring harness (to harvest plugs off of, an 88-2000 mpfi engine harness will also work)
-exhaust manifold ((the angle will be off if you use an 88-95 exh. Mani. You could modify it to work though.)
88-95 civic
-any d-series motor (the d16a6 has the holes for the intermediate shaft already drilled and tapped, for the other motors you will have to drill ((it will tell you what size of drill bit to use on the tap package)) and tap ((10x1.25)) the holes yourself.)
84-87 crx/civic
-front engine mount (you must drag one of the two holes on the right of the mount, also you have to cut the mount in order to weld the mount again to get the far left hole to line up with the one in the block)
-rear tranny mount and bracket (the two bottom holes will bolt on but not the top one)
-bottom radiator hose
-original si harness
94-2001 integra
-upper radiator hose (cut to fit)
snags and solutions:
#1-alternator bracket will hit the master cylinder. Trim the bracket to give it clearance, also factor in the rocking of the motor�.give it room. Don't cut into the slotted adjustment area.
#2- the stock fan wont fit. Get a slim fan.
Wiring:
This is the fun part :insert sarcasm:!!!! What I did was used a donor engine harness for plugs to sensors that aren't found on the si harness. sensors which you will have to add are VSS (search on here for vss info, its a subject all on its own), ELD (get this out of the under hood fuse box of any 88-91 civic,crx. its a small black box with a 3 wire plug going to it), EVAP purge (crx has one but its in the emissions box). you can cut off and tape up the wires that lead into the emissions control box, they are of no use now. I suggest modifying the harness while the new motor is in the car this way you can see which wires need to be extended. after i figured out which plugs i needed to add i ran the wires up to where the 2 main plugs on the engine harness are located, i then bought male and female 9 pin connectors from radio shack to accommodate the new wiring running from the ecu to the engine bay. I modified my wiring harness to complete obd-0 electronic advance mpfi (88-91 crx ). After doing this I used an aftermarket obd-0 to obd-1 conversion harness to run my p28 ecu (I swapped in a d16z6). If you are going to run a obd-0 motor you will not need a conversion harness. !!see wiring link below!!
Installation tips:
- only bolt on the front mount and the rear tranny mount that bolts on to the crossmember while lowering in the motor. After you have the front mount loosely bolted in lower the motor down and support it with a floor jack as well as the hoist. Now bolt the front tranny mount and bolt it up to the chassis loosely. Now the rear and final bracket, after this is on go ahead and tighten all the mounts. The motor will have a forward tilt which is completely normal.

wiring help
i found a couple of differences between my wiring and his which i will list
#1 instead of A8 it should be A6 (purge wiring)
#2 the change to A10 is not needed on this conversion (no resonator on 88-91 motors except for the d16a1)
other than those changes everything will work. i had no CEL so i know it will work.
