Replacing F22B with an F22A

[MR2_3VZFE]

Before I get hit for posting in the completely wrong site, Ive been waiting all day for a registration email from cd5tuner.com. I have a wrecked
cb7 with a lower mileage "JDM" engine. My buddy wants to buy it and install into his friend's 94 cd5. From what Ive read people have done it cause the
F22B apparently *cough* blows *cough*. Haha, I wouldnt know, thats just what I read. Anyone know of a writeup and required parts list that I can give him along with the engine? Ive searched for a few hours and Im not familiar with Hondas, so be gentle!!! Id imagine its pretty simple, wiring harness is probably different and ECU obviously, but theres always little tricks it seems.

should drop right in..

cd5 accord and cb7s are like the SAME thing..just diffirent doors, and fenders haha

y would u wanna get rid of your f22a? thats like taking a D series instead of a b18 in a civic.

but to answer your question yes same family motor and it will fit.

the cd7 is my sisters car, its getting parted out and the old f22b in the CD5 will be replaced by the superior low mileage F22a. You can see the sexiness of my sis's cd7.



Id imagine Ill be using everything from the F22a (engine, sensors, ignition controls, wiring, ecu) Be similar to my V6 swap in my MR2. But hopefully somebody has a writeup, cause Im all out of beer! Impossible to read wiring diagrams without it...

realistically, you just disconnect everything and pull the motor out

I still say that poor CB could be fixed up like new again!


I believe if you use the CD transmission, the F22A should bolt right up to everything else. If it's a non-vtec F22B2 (LX and DX models), then the wiring should be about the same as well. The header on the F22A may not line up perfectly with the exhaust, or the length might be different, so that may need to be addressed.

One thing to keep in mind is this: Putting an older motor into a newer car is illegal in many states. If you live in a state where anyone cares to look under the hood, and they know what they're looking at, that could be a problem.

if its a internal coil distributor than you have to change the ecu i think.

Rewiring can be done. Not a big deal. The PT3 from the CB7 will be needed anyway. The CD ECU will run it, but not properly.

cool definately the answers I was looking for.

I am running a 95 Accord LX P0B, for F22B2 ECU on an F22A6 and it runs absolutely perfect. Same results with PT3, PT6, or even P0H (F22B1 OBD2A ECU).
