I bought a 94 accord ex with a bad motor. I'm not looking for an upgrade I just want to get the car running. Right now there is a sale on the F23 and I am just wondering if it will fit the car or what modifications I will have to make. Thanks

 

F23, the first I come across this, I've been looking into the H23

 

Pretty straight foreword swap. The F23 will bolt right in no problem. You will need the ECU for the F23 and a OBD2 to OBD1 conversion harness as your car is OBD1. Look in the FAQ section for more info, it is a sticky at the top of the page.

 

so the f23 just bolts right up to the stock trans as well? or is it more complex than that?
this swap sounds like its pretty straight forward

 

Im in the process of putting this motor in my 93 cb. Its fairly straight forward but you will have to change a few things out.

The stock f23 driver side post mount did not work with my 93 mount so I used the 93 f22 post mount bracket.( it only has about 1/2"-3/4" of space but I think it should be ok)
The one stud on the f23 bracket is super freakin long and has a fairly long shank.

Im using my stock 5spd obd1 harness and using obd1 f22b1 injectors, POA ecu, obd1 f22b1 dizzy. Also on your exhaust, what I did was sawzall about 2" from the converter flange because my bolts had so much rust that it just looked like a blob of rust instead of a bolt and Im using the f23 downpipe and just welding a piece of stainless pipe in place to connect the system.

Other than that, its easy. Just a few things for a heads up. There isnt realy much detailed information on this swap. At least I couldnt find much info.....


Good luck!

 

You'll need to make an IACV adapter plate to retain your 2-wire IACV because the F23 has a 3-wire IACV which won't work with your '94 Accord engine harness. Then you'll need to lengthen that connector, so it'll reach the IACV if I can remember correctly.

Besides that, everything will plug right in. I'm not sure if the F22 VTEC distributor will work on the F23, but I don't see why not as they're very identical because you want to re-use your distributor since it's OBD1 and will still plug right into your engine harness.
