motor swap help

[reg7991]

I've got a 97 Civic hatch and I have some questions about doing a motor swap. The motor I want is an H22A. I found one at hmotorsonline.com and was wondering how their reputation is. Next I was wondering about the obd compatibility of this motor. It says that the motor is out of a 92-95 Prelude. I'm not worried about actually putting the motor in as they alos sell the correct axles and mount kits for this particular swap. It comes with the wiring harness, but is it going to need a lot of changes in the wiring? Any information that anyone has on this would be much appreciated. I am also planning on turbo charging as well a little later down the road.

hmotorsonline are the best.... i got two motors from them and they are A+.... adn the 92-96 are ODB 1, what you need is an OBD2A and used your stock harness, plus you should change your ecu harness to a jumper from OBD2 to OBD1... an yes you get everything but..... the harness needs to be hack to work on that civic... you might need different axles and different shifting cables....go to Honda-tech.com and find more infor about the hybrid swaps.... OR Tobi can do everything for you for a good price

you could always but a wiring harness for the obd1 -> obd2 engine swap. They are around $80 I beilive. Turbo isn't the best route on this motor stock, 5 PSI on a t3/t4 is about your max, its due to the sleeves of the motor. You would probably want to re-sleeve, and throw in some low comp forged pistons Then run all the boost you want :) Dont forget you need a mount kit www.jdmshit.com or www.HAsport.com have them.

but like Rice said, go to www.Honda-Tech.com and search in the hybrid section and the Prelude section for mounds of information. But just dont post up broad topics in there because all you will get is people telling you to search :)

Right on thanks for the information. Who is Tobi. You're probably gonna call me a dumbass for asking that question but oh well, never heard of him. I'm also planning on getting a carbon fiber hood, is there going to be any clearance issues I need to be aware of?

[RiceNmotioN]

no... there shouldent be... the only thing is if your keeping the H22 power steering you might have to shave a little off the the head light brakcet.. the hood will be perfect.... if you do decide to change the fron into a 99-00 let me know i have a carbonfiber hood looking to sell for 350....

Sorry i got here late, Hmotors online is a good place to buy. I would have to disagree with these guys on one thing though. If you live in CO. you will want to stay OBD-II for emissions purposes. Your car will no longer be emissions legal, and you wont be able to pass a smog test. Nor will you be able to sell the car without it passing. It is just as easy to swap in an OBD-II motor. and it will run like it was from the factory.
Also with the right tuning 7psi is doable and good 2XXwhp is easy to get.

one thing i've always wondered was why would you need to hack the stock wiring harness? couldn't you just use the wiring harness and ecu of the new motor?

[HONDA GHANDI]

It wont connect to the civic harness directly, they have two different connectors.

Tobi is HondaGhandi

as long as your car isn't lowered too much you should have any clearance problems.

[reg7991]

well i'm not planning on keeping the power steering but what i was kinda hoping was possible was an Integra Type-R conversion on the front end (sorry RiceNmotioN, but thanks anyways). Is that possible because i've heard that Civic and Integras have the same bolt positions for the fenders and hood and so forth. I'd like to have an H22A powered, Integra Type-R hatchie if at all possible.

Oh yea, by the way i'd just like to add that all of you guys on this forum kick ass and I have to give mad props to whoever started it. Thanks for helping me out. ;wor;

[HONDA GHANDI]

To install the integra front end you have to cut off the factory radiator support and weld in the integra support. After that it is all bolt in.


And I think the clearance youare talking about is the hood/valve cover clearance? It willbe fine. The firewall to intake manifold clearance is the one that gets tight.

I know this is a little late but I didn't read this thread before, slight correction here, the 92-95 h22 was obd1, but the 96 even being the older body style is obd2.

[RiceNmotioN]

yea the 92-95 are obd1 and the newer one are obd2

[forum]

thats not what you said earlier...

Have you done that front end swap before? What would it cost to have that done?

[HONDA GHANDI]

It is generally between $1800 and $2000 for the parts depending on where you get them, and about another $1000-$1500 in body shop labor to instal and paint. This is a ballpark figure of course too, shop prices vary.

[David]

conversions are expensive and a waste IMO. Just spend the money on that and get a turbo setup, or build up your motor.

[reg7991]

That doesn't sound like to bad of an idea. Does anyone make a sleeve kit for the H22A so that I could run higher boost levels at the track? I'll need to get all custom piping made for a turbo set-up too wouldn't I?

[David]

I know they have sleeve kits for the h22, but I dont know of any off the top of my head (try google and froogle) as for the piping, I would just make your own. JCwhitney sells mandel bent pipes for pretty cheap, get that and silicon coupling and you can have a custom made charge pipe kit for very cheap.

that or you could buy a pre-made kit for a B series turbo, I think it would all still work but dont take my word for it.

[reg7991]

What kind of turbo kit brand would you reccomend? What about the size of the turbo? Like a T3/T4 or something else?

[HONDA GHANDI]

Benson and Darton and Golden Eagle all sleeve H22's. I personally use Benson, best in the biz. AFA turbo kits, there are a few out there but the best way to go is to buy a manifold and a turbo, (different depending on your plans) and build of have th piping built. You get a better product that way and you get a hand in doing some of it yourself.

[reg7991]

Right now I am actually deployed, but I had to come to Germany for surgery. When I get back though i'll have a decent amout of money, hopefully at least, got some old bills that are still being paid. But i'd like to do this swap as soon as I could back home. I'd like to do it myself, but i'm not wanting to fuck it up at all. Is there anyplace I could go to have it done but also be able to give a hand and work on it as well?

[David]

im sure there are plenty of people on the board that would love to help you out on this kind of stuff, depending on were you live.

[RiceNmotioN]

o sorry my bad .....thank for correcting

[HONDA GHANDI]

I charge the same to do the job alone or to teach you how to do it. :D

I should just open up a school for aspiring mechanics.

[reg7991]

Well i'm stationed at Ft. Carson, but I live in colorado Springs. I may have to take you up on that offer when I get back Honda Ghandi. I'll be back sometime from mid-march to early april. About how much would it cost for the install?

[HONDA GHANDI]

You have PM

[phil]

i think you may have misunderstood me. i meant the wiring harness off of the new motor and the ecu off of the new motor.

[HONDA GHANDI]

They still have to hook into the civics harness at one point and they wont connect.
