i appologize if this is often posted, but i was wondering if anyone knows of where i can find a complete list of parts to swap a b16a into a 91 crx si. i know u need small parts like a 90-93 integra rear tranny mount, and some cables from it as well. if some 1 knows a complete list, or where to find it, i would really appreciate it. thanks

Some1 add to the list if u think i missed something...

- b16a1 complete w/ sensors, dist, IM, Exh man, TB, etc.
- ecu (pr3 or pw0)
- b series cable trans
- wiring harness
- clutch *
- waterpump *
- 90-93 teg axles & int shaft.
- mount kit
- u will need to add misc wires for vtec etc.

(* these items are not NEEDED but smart to do while the motor is out of the car.)

90-93 clutch,tranny,speedo cables?
90-93 integra rear tranny mount?
90-93 integra map sensor?

90-93 clutch,tranny,speedo cables?
teg speedo is electric. not sure on whether the stock dseries speed sensor bolts up, it might.

90-93 integra rear tranny mount?
not sure

90-93 integra map sensor?
no, stock map will work fine.

You can get 90-93 teg linkage and modify it to fit! Not that hard if you can weld or know somebody who does! The map is located on the firewall, and first gen b16 tb's dont have map sensors on them anyways! You use the wiring harness off of your old motor. If your crx is a hf, you will need to do a dpfi to mpfi conversion. I have this memorized and can help you easily! Other than that, you just add a few wires, and change a few pinouts and violla!

I have just recently done this swap on my 90 civic si.....First off hopefully ur car is either a hf or si since it makes the wiring so much easier...basicly this engine bolts right in and wires up fine all except 4 wires....the wires are knock sensor, 2nd o2 sensor, vtec selinoid, and oil pressure for the vtec selinoid.....these plug right into the pr3 or pw0 ecu, i would recomend a pr3 ecu if u can get one.........now aboput the axles needed...i have a S1 tranny, which means my engine came out of a integra xsi from japan, there are many tranny combos from the s1, y1, j1...basicly if u have a s1 tranny the half shaft on the back of the tranny is the same as the 90-93 half shafts on the b18a trannies so just get 90-93 integra axles...now the if u get a y1 tranny or a tranny out of a SiR, then u need to get a axle combo...i believe hasport has the right info on the axle combo....now for mounts u will need to get a mount kit from like hasport, hcp engineering, place racing, places like that....also a good place to get info on the swap is hybrid honda.com....lots of good info there..but basicly the swap is pretty easy...the only tedious part is wiring up the 4 extra wires which takes about 30 min if u take ur time and know what ur doing...just research it all before u do it...that is the best tool....also u will need to get new radiator hoses since the d series will not fit, not long enough and too small of a diameter....go to discount auto and get a 92 gsr upper rad hose and 90 integra ls, or gs lower rad hose....also u will need a 90-93 integra ls, or gs throttle cable, and it will just bolt right in and work auto or manual throttle cable will work....the d-series cable is too short....hope this helps out a little with the swap if u have any questions just pm me...

Actually, the HF is MPFI, the DX is DPFI

and for the 2nd o2. its not an "after cat" o2. I believe the ecu is setup to read 1 o2 for cyl 1 and 3 and 1 o2 for cyl 2 and 4.

that way it can compensate lean conditions for each pair instead of a general change.
