I recently bought an f22b from tigerjapanese. I thought since I had a 96 Accord that was already Vtec it would be a simple swap. However it's not. I have run into several problems and it's been a few years since I performed my last swap so I'm a bit rusty.

1st problem wire harness that came with the motor is completely different from the one in my car. I swapped the harness from my car to the motor so that my distributor would work with it because the wires did not match. Anything I should know? Will I need a different ECU?

2nd I need to swap the crank position sensor, do I need to swap the oil pump as well?

3rd Vtec solenoid has one more wire than my stock one..what do I do? Use my stock vtec solenoid??

Is their anything else that I should know? Is the f22b that tiger sent me obd1 and how could I figure out if it is. I know my car is obd2 and I ordered the motor for my car but surprise surprise it's not going to be that easy.

PLEASE help and if anyway possible could you text message me or call me if you can 228-344-5830 if not just post help here...

The CKP sensor is located in the distributor on JDM motors. You'll probably want to replace the oil pump with a USDM OBD2 version if you want to continue using your stock ECU.

Anything else you could let me know? Know anything about the different Vtec solenoid? Oh and how do I tell if it's obd1?

adams90crx@msn.com

Sorry the jdm vtec solenoid has a black sensor in it but my usdm one doesn't, I have nothing to plug into that sensor so do I just leave it unplugged or is there something else I need to do. I think it's the oil temp sensor?

adams90crx@msn.com

Figured it out I think jdm vtec solenoid has an oil pressure switch that tells the ecu it has 55psi before it will allow vtec to engage. I just simply have to splice green/yellow wire coming off solenoid into blue/yellow wire coming off pressure switch? Pretty sure this was done on my ls vtec with jdm head? Is this right? I found it on another site.

Or should I simply use my usdm solenoid?

Can you take a picture of it?

adams90crx@msn.com

Here's a picture of the JDM Vtec solenoid...

Another question. HOW in the H to you get this stupid crankshaft bolt off. I have NEVER in my life not been able to take on off with ease. I even bout the crankshaft tool to hold it in place. It's not budging at all, even with my kobalt impact. Anyone know any tricks or should I go borrow my buddies ingersol rand 600ft lb in reverse impact lol.

Is there anyone that could answer my original questions?

Part of the issue is you are OBDII and the motor is OBDI, so you will have to either downconvert the car to OBDI (not that bad) or upconvert the motor to OBDII (more difficult IMO).

However if you downconvert the car the OBDII scanner port used for emissions testing becomes worthless and your car would not pass inspection (if that is required where you live)

I would suggest getting an OBDII to OBDI conversion harness for the ECU, and follow some of the H22 swap guides on how to rewire the stuff required. (I used this with my H22A http://www.phearable.net/shoppingcar...ness-p-33.html )

*edit* I would also suggest running a chipped ECU (P28 or similar)

I don't want to go to obd1 I want the car to remain obd2, it's not a race car just going to be a daily driver. How is it that I this motor is obd1 when I ordered it for my vehicle specifically. How do I tell obd1 from obd2 from looking at the motor?

I just need to know if what I'm doing is correct. I'm pretty sure all I have to do is use the f22b1 parts on my f22b which would be HELLA cheaper being as I'm totally broke now.

Did I mention that I still do have my original motor so if I just need to swap parts please advise. I mean if everything will bolt up why can't I just swap everything onto the block and head?

Off the top of my head distributor, injectors, and probably a 2nd O2 sensor for the motor to be converted over.

*edit*

that VTEC solenoid as well

the 94-97 had the f22b2 and f22b1 in terms of I4's. If I remember correctly, most of the 94-95's are OBDI and the others are OBDII. I think you should just sell that motor and pick up the correct one from a junkyard for a couple hundred. f22b2's are cheap.

adams90crx@msn.com

f22b1 came in my car and just selling this motor and picking up another one isn't an option that would require more money that I do not have. If all else fails I rip it down to block and head then put EVERYTHING off of my old motor=free... but I would rather just change what few things I have to. Other option is to send motor back for a refund.

19Accord97

Why not just send it back and call it done?

It'll be a heck of alot easier to pick up the same motor that will work. Just make sure the OBD is correct and it is an f22b1 and you should be good to go.

adams90crx@msn.com

because sending it back is going to cost me $300

adams90crx@msn.com

Ok I had a talk with the technician he says the motor is the same and it's out of a 97 Accord. It is the same obd but I have to add the crankshaft sensor, distributor, intake manifold, and vtec solenoid. So that's really A LOT easier than sending it back since I have every single one of those parts on my old motor. So at the end of the day what I have learned is JDM=GAY.

If it's a F22B, it isn't the same and would not be USDM. Every USDM motor would be either an F22B2 or B1.

*edit*

And if you have to add those sensors it is definitely not the same OBD level. What tech did you talk to?

adams90crx@msn.com

The technician at tigerjapanese. The motor is from a 97 JDM accord who said anything about it being USDM? I have also a USDM motor with all the parts I need to interchange. f22b is the JDM equivalent of an f22b1. The reason you have to change these sensors is because in japan they put the crankshaft sensor in the distributor and have an extra sensor on the vtec solenoids. I'm not questioning what this guy says he works on these motors everyday and is completely right.

Your motor is not the same OBD level is what I was getting at, which is why you to swap stuff over for it (the car) to remain OBDII and the scan port to be active. Since the technician said 'they're the same' it is not exactly correct. Yes they are similar but they are not 'the same'.

You still run into the issue of VIN plates not on the motor (if that is a concern)

I did the OBDI H22A swap in my '96 (OBDII Accord, so I had to deal with similar stuff.

adams90crx@msn.com

I would just swap it to obd 1 if I could find an engine wiring harness or guide but there is absolutely nothing on it and this seems to be the other option. I don't see them refunding me the money so beware of tigerjapanese :/. I used to like JDM but that's when I was messing with b series and oh god do I wish this was still a b series lol why do f series have to be more complicated it should be easier..

TheMuffinMan

Honestly would not be too bad - the biggest thing is the ECU wiring harness which you can buy. Other than that I wager most other stuff would carry over.

adams90crx@msn.com

What about the engine wiring harness? Do you know where I can get a wiring guide? I mean if it's possible I would love to keep the JDM motor completely intact and just change the wiring but at this point the intake manifold, vtec solenoid, crank sensor, and distributor all have different plugs on so they would work with the cars harness..

Oh btw thanks for all your help man, I signed up at accordtuner.com opened the same thread and all those noobs did was bash me because I didn't know that much about this f series swap. At this point it doesn't look like many have been blessed with this inconvience lol.

I have a 96 Accord EX with the stock F22B1 engine, and I also considered buying a JDM F22B SOHC V-tech engine. After a lot of research, this is what I found:
In USA all 96-97 Accords are OBDII, the 94-95 Accords are OBDI
In Japan 94-97 Accords are OBDI
Therefore, there is no JDM F22B SOHC V-tech OBDII available.
There are (1998 and up) JDM F23 SOHC V-tech OBDII engines available; however, I do not think that the sensors or wiring are identical.

I would suggest that you just use the long block from your JDM F22B SOHC V-tech OBDI engine. Swap over your complete intake manifold, fuel system, distributor, and any sensors that are different. You will also have to swap over your oil pump with the crank sensor. No wiring changes, leave it OBDII.

Because of all these differences, I am currently looking at just buying a 1996 USA F22B1 engine with 100K from a salvage yard. A few more miles, but a lot less hassel.

Is there no crank sensor bypass like for the civics and integras for a 1997 accord lx with a jdm non vtec motor?
