H22A Swap FAQs

[wadzii]

H22 Swap Faq's General Swap Info Use the accord wiring harness and lengthen/modify the harness to fit the H22. ECU Wiring For Obd1 ecu's vtec soleniod: Pin A4 vtec pressure switch: Pin D6 knock sensor: Pin D3 Secondary Intake Soleniod: Pin A17 Use accord axles Buy a manual for the year prelude your H22 came from, the year of the ecu you have and the car. ex. 97H22 with p13 obd1 ecu into a 94 accord. Get a 97 prelude helms, a 93 prelude and a 94 accord helms manual. Goto www.helminc.com to get them Air Conditioning To keep ac take the bracket off the F22 and put it on the H22 and use the accord compressor Power Steering Use the prelude pump and bracket For 5TH gen Only Use 92-96 prelude timing belt side mount, keep in mind that you will have to grind it down to fit, and the rest accord mounts Swap pin A6 with pin A11, the accord is unique from other hondas. those 2 wires control the o2 sensor heater and egr control soleniod. they are backwards in the accord The exhaust must be reduced in length and it is reccomended that you get a cat to match the year header you have. (ex. if you have a 94 h22 header get a 94 prelude cat, etc) the 97+ header is different and the cat isnt the same. To keep the Powersteering you must have a custom line made using the lower 1/2 of the accord line and upper 1/2 of the prelude line OR use a 97 prelude line For 4TH Gen Only Use all accord mounts The exhaust bolts up to 93-96 Prelude header No pin swaping is required No changes need to be made for the power steering hose obd2 engine in a obd1 car ex. 97+ H22a4 into 90-95 accord You must get an obd1 ecu, obd1 injectors and obd1 distributor. obd1 engine into obd2 car (5 Spd Only) ex. 93 H22a into 97 accord Get your favorite obd2-obd1 conversion harness, skunk2, hondata, etc Move the crank angle sensor wires from the crankpully/timing belt area to the distributor. Repin the distributor connector using the obd1 plug that should have come on the engine, put the 2 wires you just moved into the 2 left over pins on the plug. Internal/External Coil Issues If your car came equiped with an internal coil then the jdm h22 distributor will plug right in no problem. However, if your car had external coil then you will have to modify one plug. The plug you will need to modify is the plug that went to the stock coil. There are is a yellow and a yellow/black wire, splice those 2 wire together. The green wire is useless, dont worry about it What Cap To Use For JDM internal coil use 00 civic SI or 90-93 accord ex cap and rotor For USDM internal coil.... DUHH!!! use 93-95 prelude vtec cap MSD Install For External Coil equiped cars Cut the Plug that went to the stock coil off, splice the yellow and yellow/black wires together, and you will also need to hookup the small red wire from the MSD to these 2 wires. The green wire is the trigger, connect it to the White wire on the MSD box or the negative side of the coil if you are only adding a coil For Internal Coil cars You will need the MSD conversion distributor cap. Take the coil out of the distributor. Run the 2 wires that orignally connected to the coil out through the hole in the cap, rember which one is negitive and positive. Connect the positive to the small red wire and the negitive to the white wire. ApexI VAFC Settings These settings are different for each car, use these as a baseline and get your car on a dyno -2 from 0-4800 wide throttle -5 from 4300-8000 wide throttle vtec low<>high 4800 Vtec high<>low 4600 Throttle point low 10 high 50 1/4 Mile times for your Hybrid It really depends on how well you can drive and the condition of your engine. We have seen anywhere from mid-low 14's to 16's in accords with H22 swaps. 6TH GEN TECH There isnt much info on 6TH gen swaps. Aperantly the timing belt side mount is an issue as well as the immobilizer Transmision Codes thanks to V4lu3s m2a4...jdm prelude tranny non-lsd m2b4...jdm lsd h22a tranny m2s4...usdm h23a1 tranny/possibly also JDM f22b tranny as well m2f4...usdm h22a1 tranny m2ya...usdm h22a4 tranny m2u4...usdm type sh tranny

Just to add:

A 97+ lude p/s bracket with accord p/s pump and line is another option.

For cat just get universal, anything oem or made to fit will be $$$. I paid $87 shipped for my carsound cat and the install was covered in the swap price since you got to mess with the exhaust anyways welding.

If you use an OBD2 engine on your OBD2 Accord, you can keep it OBD2 for smog legal purposes....no need to convert to OBD1. You can't use a 97+ Prelude ecu because of the immobilizer. However, if you can find a 96 USDM P13 or a JDM P5M ecu, you'll be fine. JDM ecu's do not have the immobilizer. I was able to pass smog and the state ref here in California. 100% Smog Legal Swap!

its a civic, you dont need ps... but if you must, then you have to use a prelude pump and im not sure of the line you need. we usually throw ps out.
