so i bought a used jdm f22b engine for my 96 accord to replace the f22b2. now im running into a few problems. there are several things i can see that are physically different between the two engines. i think the new jdm engine is obd1 but im not sure.

-egr valve is a different design
-exhaust manifold has different bolt patter for front pipe
-no external coil on the new engine
-different electrical connector on distributor

i think the exhaust manifold will be an easy fix, just swap the old one on to the new motor. and i think that the distributor will be an easy fix as well, simply swap the old one to the new engine and bolt up the external coil to the block. as for the egr valve: the bolt pattern where it bolts to the intake manifold is the same for both. can i just swap out the egr valve and have everything work ok?

so these are my ideas. is there anything else that is different from the two engines. is there anything else that needs to be changed over or swapped? would i be better off just swapping the whole intake manifold? any replies would be greatly appreciated. thanks!

I always swapped out the intakes on those imported engines, the emissions are always different in Japan.
But I've had good luck with the basic engines.

how bout the distributor?

jdm f22b dohc?

redline870

no jdm f22b sohc non vtec

redline870

exact same as the engine that came out of the 96 accord, just jdm version and possibly obd1. im not sure if its obd1 or obd2.

OBD1 or OBD2 F22B doesn't matter about the block. You should be able to take all of the sensors, coil, distributor and just about anything else you need from your USDM F22B2 and swap them over to the JDM F22B. The SOHC Non VTEC JDM F22b is identical to the F22B2.

There is one exception. You may want to see were the CKP sensor is. (crank position sensor) I believe that the OBD1 CKP is located in the distributor were the OBD2 (96+) is mounted on the oil pump housing behind the timing belt cover above the crank. You should see the wires coming out from behind the plastic cover if it's OBD2.

This will ultimately be your decision maker on weather to convert your F22B2 wire harness to an external coil with an OBD1 dist. or take the oil pump from your OBD2 block and swap it with your OBD1 oil pump. Then you can run with the OBD2 dist. and external coil setup.

IMO i think you should take the extra time and swap the oil pumps....i have seen it done and its apparently not that time consuming if the motor is on the ground

so the wires for the ckp sensor will be coming out from behind the timing belt cover?

how do i go about to "convert your F22B2 wire harness to an external coil with an OBD1 dist." do i take out the internal coil on the obd1 distributor then put an obd2 cap and rotor in place of it? and what about the ckp sensor if i do that? where will this connect to the wiring harness?

On an OBD2 block yes.

I'll have to get back to you after work when I have more time.

Here is the OBD1 dizzy wire diagram.

right click the image and save to your desktop. or drag-n-drop it to your desktop.

The OBD2 wires that you are looking for are a blue wire Pin C2 on the ECU & a White wire pin C12 on the ECU

Unfortunately I am unable to do up a Step-by-step with pics as my engine bay is empty but I'll see what I can do.

Cheers

i really want to do this the right way and swap the oil pumps but i dont know about taking a pump with 170k and swapping it with a pump that has 50k. what do you think? think i should just bite the bullet and buy a new oil pump? or use the old one?

GhostAccord

You could remove the oil pump from your older OBD2 engine and check the inner and outer rotors to see if they are within spec.
Standard is 0.02-0.16mm (0.001-0.006in) and the service limit is 2.0mm (0.008in)

But if you really want piece of mind a new one would be the way to go. Also remember to buy new oil seals. If you have the money, and it hasn't been done already, you could do the timing belt, balance belt and tensioner while you have the cover off.

As for getting to the pump You will probably require the use of a Hex 50mm pulley holding tool in order to get the harmonic balancer/pulley off. I bought mine for $25 from a local parts store. I think I remember someone saying that some parts stores in the US rent them out?

redline870

-i dont know what the inside of the pump looks like so i dont know how to check the rotors on the pump know of any pics i could use for a reference?
-by new oil seals, do you mean just a new front main seal? is there a seperate seal behind the pump or any other seals to be replaced?
-i already have a new timing belt, balance belt, and water pump. the dealership told me not to worry about the tensioner.

I really need for someone to help me find the connector from the harness in the engine bay that attach to the CKP sensor in the crank. My car still has the OBD2 harness but I can't find the dangling connector.

GhostAccord, I just checked my engine and it looks like the it has an OBD2b (small plug) distributor. There's one single plug with 7 pins and a smaller with 2 pins (black/yellow wire and dark blue wire) that looks like it's been spliced out of the harness and attached. Is this a CKP bypass or am I looking at a mod to make the OBD2b work with an OBD1 JDM engine.

Anyone can help shed some light on what's going on?

I've found another solution since my Honda Oddy now has an OBD1 Engine and Auto Tranny, I'll convert to OBD1 ECU using the method found here:

http://forum.pgmfi.org/viewtopic.php?f=54&p=119274

I've already made the harness and I've got a chipped P75 ordered with the Integra LS bin and ingnition and engine maps of Accord burned on it.

The ECU is on it's way. Should this work?


Thanks

Hello..ok i bought a jdm f22b sohc vtec to replace with my f22b2 in my 96 accord lx auto...i was told that i had to change out the oil pumps because of the crank postion sensor in the 96 n up accords, so i had the pumps changed, i also bought the correct ecu that i have to use, but im havin trouble finding out what distributor to use. I bought a 96 accord ex distributor but the plug dont match the engine harness out of my old motor because it has an external coil and the one i bought has an internal coil...so my question is do i need an accord ex engine harness? Is there anything else im missing to complete this engine swap? I want to keep everything obd2

nus_dogg

DVSRM450, Why don't you just swap over your old distributor from the F22B2?

SOLVED!!!!>>
iI FOLLOWED THE INSTRUCTION IN THE LINK ABOVE TO CREATE MY OWN HARNESS COVERTER AND USED A CHIPPED P75 ecu and works like a charm ; no idle problem or misfires anymore. no more ecu light.
thanks to all for inputs

I have a 97 accord lx 2.2l non vtec and I want to replace my f22b2. I've looked through a few forums on where to buy a used engine and so far I think ima go with a f22b I found on jdmracingmotors.com and I wanted to know if I would have to switch out parts from my old engine if I do get it. Any edvice will be appreciated.
