Ok here is the deal I already posted that I just bought a H22 for my 96 accord. The Engine code is H22A4 since it came out of a 2000 Prelude SH. Now I was doing some homework on it and this is what I came up with

( " The only H22 to avoid is from the Type SH Prelude. The brilliant torque distribution system (an electronically controlled box of clutches bolted to the block that Honda calls ATTS) replaces the intermediate shaft and its mounting bracket. The engine and transmission code to avoid is H22A4 and M2U4, respectively. Again, when someone actually swaps this in functionally, let us know. " ) from this site
H22 Swap the article is titled Picking the Engine.

The reason I am asking is I thought that H22 was very friendly going into the accords. I am just a little discouraged now, when I should eb happy. Can somebody please tell me that. Someone has put a H22A4 into an Accord before. Please anyone info can be helpful.

Well, I dropped an H22A4 into my 97 Coupe. I'm actually using a non-SH engine from a 98 model. I'm using my original Accord intermediate shaft and axles with my swap. I don't know too much about the ATTS unit but it seems like you can ditch the original ATTS unit and all of the junk it comes with and bolt up the Accord shaft. Is there any difference in the SH's tranny??? Also, if you want to keep your Accord OBD2, you'll need either a JDM P5M or a 96 P13 ecu.

I will prob be keeping my car OBD2 for now since the engine I got. Is already OBD2, but why would I need the JDM P5M or 96 P13 Ecu for when I have the P5P Ecu which goes to the 2000 Sh engine that I got. Did I miss somthing there. Thanks for the info though bro much appreciated.

The US computers have an immobilizer. Something about a computer chip in the prelude key that tells the computer its ok to start. I used my original Accord computer for a while until I found a JDM computer.

I know a guy that has a 96 P13 for sale, also about the SH you need to get a base model tranny and also you need to build a bracket for the accord halfshaft in order to move the bolt holes from one side to the other. Search my name here and on H-A.net and hondasociety there are alot of post from me about this swap. I did it about 2 years ago

PS Ron where have you been man glad to see you are still around hey hit me up i need some help I still have CEL code 92 with the 96 P13 hit me up

so wait let me get this straigth I need the base SH tranny I cant use the one that came with the 2000 SH that I bought. Also on top of that I need the 96 P13 Ecu and i cant use the one I have cause of the immobilizer. Now does that have anything to do with this ATTS that I am reading up about. Is that something that is going to srew me in the long run. Once again I appreciate all the help guys. I just dont want to regret getting this 2000 H22a4 since it so pristine you know.

no you need a prelude base model tranny the only thing that you can use from the swap that you bought is the long block. The 96 P13 is the only US spec ecu that is OBD2 that will run the car

any idea where i can find a prelude base tranny. If you dont mind why cant I use the tranny that I have, I am sorry for all the questions I am noob at this. Also i have been searching for 96 P13 ecu and all i come up with is the OBD1 version.

accordhybrid

the reason that you can't use the tranny is beacuse of the ATTS system it uses a tq converter that allows it to work like a LSD. So with the tranny mounted to the and the ATTS system installed the halfshaft and axle don't work.

Go to slhonda.com and search 98 prelude sh 5 spd and you will see the tranny and the ATTS system and it should make more sense

Also there is no such thing as an OBD1 96 P13

92-95 P13 = OBD1
96 P13= OBD2
97-01 P5P= OBD2 Immbolizer
