How's it going fellas?

I drive a 99 4cyl 5spd Accord, and I have already made my mind up for a H22 engine swap. However, I am currently standing at a T-intersection at which I cannot decide whether I should go for the H22 obd1, or obd2. I have talked to different dealers and they offer a complete H22 OBD1 swap for circa 2700 dollars, while 3000 dollars for a H22 OBD2 swap. I know a few mechanics and they have different opinions regarding this matter. One says that since my car is already an obd2, it would be much easier and less troublesome, if I installed an H22 obd2, while another mechanic tells me that I should go for the obd1, since its easier to tune and modify, and it has less restrictions and sensors.

The H22 obd1, seems to be the lighter and more tunable engine, but I'm worried that I am going to have to pay more money than I expected, due to more labor time and parts, e.g. wires and harnesses. Also, it seems that if I wanted to go forced induction the H22 obd1 would be prefered, since devices like Hondata is more compatible (and/or perhaps it only works) with OBD1 other than OBD2. I'm not too sure about the AEM EMS, but it seems as if Hondata is prefered over the AEM EMS.

Any suggestions and info would help greatly, but I'm especially interested in finding out what H22 OBD other 6th gen accords are using.

Thanks in advance,
Bjorn

 

and obd2 swap would be easer, since you car is obd2

 

Thanks for the reply, but in what sense is it easier? Are we talking an extra hour or two worth of re-wiring? Re-locating a few parts?

 

yah im pretty sure with just the wiring, thas the only thing, dont quote me though

 

go obd1 this way if you wanna do any ecu options for upgrades,you have a lot of options be it turbos or na, if your looking to have a daily driver
and a motor swap and thats it well then do obd2.
i have an obd 2 car (97) and did an obd 1 conversion. it was not hard at all
what so ever. the down side my car will never come close to passing emissions.
later

 

I'm bringing this post back from the dead to ask an easy question (for you guys). Which year H22 engines are OBD2 in both the USDM and JDM? Thanks Alot.

 

Lol, it's funny to see what I said back then.

Anyhow, the OBDII would be 97 and up, while H22 from 92-96 is OBDI.

If I'm wrong please correct me.

 

I know the 96+ Accord engines are OBDII, so then the prelude engine is different from that?

 

I also would suggest going with OBD1 for the reasons you have already clarified. Please do note though that if you are very serious about tuning once the engine has been put in (which it sounds like you are since you are considering Hondata), is that more than likely you will need to resleeve the engine block. Why this is needed is because of the overall weekness of the stock sleeves that come in the block already. Maybe you already know that, I'm just stating if you did not. Good luck on your swap bro!

ob1 one for the extra tuning options.

I have a 98 with 99h22a4 in mine wich is obd2 but i converted over to obd1.

 

the 96 USDM H22 was OBDII and it lacks the vehicle immobilizer that the 97-01 ludes had. this why a USDM 96 P13 ecu is so sought after and is $$$ if you can find one.
