I just bought a H22 to swap in to my 94 Accord EX. The problem is it is an OBD2 motor. I know I need injaectors and distrutor. My question is would it be easier to find a OBD1 ECU from a H22, or can I get the stock Accord EX one chipped to run it. Please let me know what I need to do, Thanks.

 

Should have read up on everything and had all your bases covered before even deciding to do such a project. This is why swaps go wrong and things get messed up. Accord ECUs are absolutely useless when it comes to chipping/modifying, they're setup differently than civic/integra ecus. Either hunt down a P13 or buy a Chipped P28 with H22 basemap from Xenocron/Phearable/whatevercompanyyou'remorebiasedtowards. Chances are it'll probably be cheaper to just get a chipped P28 because P13s are pretty expensive last time I checked.

 

i wanna do a h22 swap on my 94 accord lx 2.2 automatic, any suggestions?

 

will i need engine mounts?

 

would i need to change my tranny too?

 

doin an h22 swap what exactly am i gonna need to change out besides the motor?

 

I recently crashed my H22A swapped 95 accord. It ran really sweet, innovative mounts, ob2 japan acccord ecu and original prelude tranny.

 

I have 95 oem parts for sale. I have oem rear taillights, oem front turn signals, front strut bar and replacement rear bumper all for $50.

 

I have been doing a lot of research on the swap. is the p28 a direct swap as far as wiring? is the p13 a direct swap as far as wiring?

 

Both of them will require you to swap pins A6 and A11, otherwise, plug and play.

 

Thanks dude it seems that you are the only one willing to help.it is only A6 and A11 other wise plug and play awesome. Any other helpful info for me. lol

 

You can use your f series tranny it all bolts up the same. Im pretty sure you can use the same mounts to because in the older accords like mine its direct swap also. As for ecu choice p13 is your BEST choice for stock setup. P28 is mainly used because they are easily tunable, lower vtec engagement (5200 for the auto p28) and they are cheaper. Choice is all up to you tho, good luck with swap

 

I knew about the tranny and from what I have read I just need the drivers side mount from a prelude.The main concern was converting the OBD2 motor to OBD1 and the ECU. From what I know my Accord harness will work i just have to wire in the knock sensor. Can i use anything from the f-series to convert the motor to OBD1?

 

A guy sells vtec wiring kits on ebay. The only difference between that motor and obd1 is that there is an extra sensor on the oil pump which you will just leave disconnected since you will be using an obd1 distributor that will be taking the place of what would otherwise plug into that sensor. Then ya you just need to source a p13 jdm obd1 intake manifold with the works. This will include injectors etc etc.

You can use hondaautomotiveparts.com to check and see what other sensors other than the oil pump sensor are the same for obd1(93-95) p13's vs obd2(your motor 1998) or someone else can just chime in with info. I would think that if your harness connectors can plug into it it should be fine.

 

You think I have to change the whole intake manifold? I was told just the injectors needed to be changed. Wow, I hope not, this could get costly. I got the motor for 500 bones. I really want to get it in the car A.S.A.P.lol but who doesn't . From the research I have done it says I only have to add one wire for the knock sensor and nothing else. This was because I have an EX with a SOHC VTEC allready I know it is the F22 but I can not remember the rest I want to say B1 but I can't remember.

 

No, you don't need to change the whole IM unless the H22 you bought comes with a 3-wire IACV(I know the Euro R does) then thats when you get yourself an OBD1 H22 IM that has a 2-wire IACV. That way, you can plug in your 2-pin IACV connector from your F22 harness.

All you need is a OBD1 JDM H22 Distributor cause it'll be a plug and play into your OBD1 EX harness. Same goes with OBD1 H22 Injectors because they're peak N hold, not saturated injectors(OBD2). You will only add Knock Sensor and IABs if you are running a P13 ECU. Running a P28 chipped ECU, you will not have to wire up those two things, because the P28 doesn't support them, so thats how many ppl by-pass them to save work.

 

the motor I got is USDM. That being said that is what i thought nut I guess i wanted reassurence on it lol. So you thing the best idea is to run a chipped p28 in stead of the p13 just for ease of the swap?

 

nus-dogg are you on cd5tuner as well?

 

You can still get a JDM OBD1 H22 Internal Coil Distributor, because the F22 EX harness is a internal coil setup. So by getting a internal coil dizzy will be a plug N play. Thats what I have. I would get a P28 chipped ECU. You can bypass the KS and IABs plus you can go in for a dyno&tune session whenever you're ready to make more power.

Yes I am. I'm everywhere; any Accord forum, you'll find me.

 

lol any Toyota forums ?

 

im thinking of swapping out my h22a4 for a h22a in my 99 lude... im still undecided but leaning towards the obd1... people are telling me it will be a much easier swap if i stay ob2 but im thinking i might get into adding some goodies that ill need to tune.. whats your guys opinion on it? would it be a much easier swap staying obd2???what else beside the harness conversion am i gonna have to change??? thanks for the help i plan on getting motor this week as long as i can decide on which route im gonna go lol

 

id like a bumber, rear and front do you have both?

 

I have a newly built H22a swap and it runs really rough. I can't figure out what is wrong with it. Any suggestions.

 

well thanks for bumping a year old thread, Well we would need alot more info....
