While wanting to swap, I see that the earlier generation motor/tranny packages are reasonably cheaper in price. After looking at 92-96 and the 97-01 H22a motors I noticed they have almost the exact same specs in HP & Torque. I am wondering if anyone could tell me what the prime reason between the motors as to why there is such a price difference. My first thought was age, but I don't think im completely right.

 

I'm not sure, but maybe the old the cheaper?

I also heard that it's illegal to put an engine in your car that's older then the car itself, especially in CA, since they're very **** about it. (e.i: 92' h22a in a 1997 accord)

 

im researching this swap myself ... i believe the the a1 has a closed deck and a4 is open ... meaning it has "floating cylinders" or whatever ... but pretty much its just a difference in emissions ... a1 is obdI and a4 is obd2 ... im doing an h22a1 swap screw californias law ... besides its not going to stay stock which is going to be illegal anyway ...

 

Im in Southern CA. Only thing holdin be back right now from the swap is paying someone for labor. We should meet n' swap together.
6th G's unite.

 

i dnt know the difference, but i have a 2002 accord coupe with jdm 92-96 obd1 h22a with the mb24 lsd tranny, and it runs hard. i took out a s2000 already, the swap is definetly worth it.

 

that would be cool as hell man but my buddy is going to do my swap he lives out in covina/industry area ... im out here by the san fernando valley myself ... i almost have all the money to finally do it

what ecu are you running? stock or modded h22a? well its good to hear the capabilities of the swap ... so then i will have no problem ripping a rsx type-s in half then yay lol ... my goal is to be able to rape the evo of some guy who thinks too much of himself

 

Was he trying to race you?

 

chip P13. Thats if I swap the motor. I think Im just looking at a 5spd swap right now.

 

HaHa thats funny I sold my 9 MR to build my H22 accord

Anyways It is correct that H22a and H22A1 have closed deck.
The H22A4 is open deck. also The JDM H22A has roughly 10.6:1 compression
Where as the USDM H22A1 and H22A4 have 10:1 compression and the red top H22 type S motoor has 10.999:1 compression....... roughly

 

i was contemplating on either the h22a1 jdm or h22a4 usdm ... what are the differences or pro's and con's if you will ... between those specific motors as far as hp & tq and any other goodies?

 

Go with the JDM motor unless you are trying to get Bar'd. I prefer the Closed deck block and you'll have more compression.

 

i actually wanted to do the swap myself. so i can tell you ask much as i know. and some of my recommendation along with other people recommendation on 6thgenaccord. FIRST OF ALL YOU CAN RUN A H22A4 LEGAL, ON GUY HAS IT AND IT PASS ALL SMOG AND STUFF. IDK IF HE ADD A WHOLE OTHER STUFFS TOO.

BUT I HIGHTLY RECOMMEND GETTING A USDM H22A4, SINCE IT EASIER TO WORK WITH, AND MOST LIKELY WILL PASS SMOG. OH AND YOU WANT TO GET THE ENGINE WITH THE SAME YEAR HAS YOUR CAR OR NEWER. LIKE I HAVE A 99, SO I NEED TO GET LIKE 99 OR ABOVE. (THAT IS WHAT I HEARD FROM A SHOP). AND YOU MAY WANT TO KEEP ALL EMMISSION SENSOR ON THAT H22 SINCE YOU GOING TO NEED IT ANYWAY IF YOU WANT TO PASS SMOG.

THE MOST IMPORTANT THING IS THE ECU WHICH YOU CAN HAVE A COUPLE OF OPTIONS.
1. CONVERT YOUR ECU NOW TO OB1
PRO: EASIER TO TUNE TO MAKE MORE POWER
CON: WILL ALWAYS FAIL SMOG CHECK
2. FIND obd2a p13-a12 ecu from the 1996 Prelude Si 5spd vtec
PRO: STAY OB2 AND PASS SMOG
CON: HARD TO FIND SINCE IT ONLY FROM A SPECIFIC PRELUDE AND ONLY IN 96
3. GET A AEM EMS
PRO: DON'T HAVE TO CONVERT ****, JUST PLUG IN THE ECU THAT YOU HAVE ON YOU ACCORD NOW AND JUST TUNE IT. CAN TUNE FOR ANYWAY YOU LIKE. AND USE IT TOO IF YOU DICIDE TO GET MORE HP. BASCICLLY YOU CAN USE IT FOR ANYTHING THAT YOU PLAN TO DO LATER ON LIKE TURBO, OR JUST TUNE YOU CAR TO THE MAX AND GET THE MOST POWER OUT OF YOU NA ENGINE.
CON: NOT PASS SMOG, COST AT LEAST $1000

YOU CAN CALL THIS SHOP CALL SWAP SHOP RACING IN COVINA (PHONE# 626-261-4052). I CALLED THEM AND THEY GAVE ME A QUOTE OF $2500 FOR THE COMPLETE SWAP. BUT THEY DON'T DO TRANSMISSION CONVERT FROM AUTO TO MANUAL CAUSE THEY SAID IT TAKES TOO LONG TO DO ON OUR ACCORD.

WELL THOSE ARE THE INFO I GOT FROM PEOPLE SO FAR. HOPE IT HELP YA SOMEHOW. I PERSONALLY KIND OF GIVE UP ON THE DREAM OF SWAPPING ENGINE IN MY CAR SINCE IT KIND OF HARD TO FINE THE RIGHT STUFF. I THINK I'M GOING TO GO THE ROUTE OF ADD BOLT-ON (MAYBE A TURBO ROUTE IF I HAVE ENOUGH MONEY) AND AEM EMS, AND TUNE THAT **** OUT OF THE ENGINE. I THINK IT SAVE TO SAY THAT WITH JUST BOLT-ON AND EMS I SHOULD MAKE 180HP ON THE CRANK. AND TURBO OH BOY I CAN GET MORE HP OUT OF THAT. THE GOOD THING (KIND OF HASSLE TO) WHEN IT COME TO SMOG TIME, I HAVE TO TAKE EVERYTHING OUT AND PUT ALL STOCK PARTS IN THEN TAKE IT TO TEST. ONCE PASS TEST THEN PUT EVERYTHING BACK ON. THAT MY .2 CENT ANYWAY.

 

good info guys! like i mentioned before im not planning to keep it stock so i wont pass emissions regardless ... so jdm h22a1 it is and since i cant afford a aem ems im just going to go with a hondata s300 and an obd2b to obd1 jumper harness

$2500 is that for an h22a1 or h22a4 and what does that include ... tranny, harness, ecu?

 

98 and newer A4s have 55mm Main bearings, 97 and prior have 50mm

nice find jweller that is exactly what i wanted yay thank you

 

im runnin a p13 with a messed up tps, and we did a third gear roll, s2000 was was half a car away at 110mph, but go jdm, it has a higher compression if im correct

 

i've got a 6th gen accord and would love to put in a h22a or h23a vtec but the car is too heavy!!!figure a prelude is lighter than ours(not by much,but enough)and they're quick but in a 6th gen I can't imagine it being faster than a stock prelude,that is if the accord with h22 is not modified.correct me if I'm wrong..I never drove an accord with a h22,only civics.i'm probably going to go for an j32s with a 6 speed trans for my car.but I still don't know what I want.anyways good luck with your swap.and us 6th gen guys should unite.it's nice to see accords tastefully done up an whipping ***.

 

yes unfortunately us 6th gens are heavier than a prelude but not by much ... personally im doing this swap because its the cheapest swap and easiest swap ... also it opens up a lot of upgrade possibilities since the H series motors have a larger variety of upgrades than F series motors ... if i had the money for a j32 swap id be in heaven lol

 

Actually, a 6th gen DX is lighter than a 5th gen prelude, and the LX coupes are within a value meal of being the same weight. I'd guess the VPs are lighter or equal as well. I've got a friend with a swapped DX and it f-ing rips. The 5th gen lude is a fat pig, go check the official weights of the cars. I'll bet you'll be surprised.

 

how about 6th gen sedan .. lighter than coupe? ...

 

i believe so, i know in civics, my buddies 1995 civic coupe is heavier than my friends 1995 civic 4 door

 

Well you wont be able to rip an RSX-S in half. Its lighter,has better gearing, better VTEC, and the same HP. And well dont even approach the EVO. You got mods to do to beat those cars. Now, you can use whatever year motor you want. However all of the emissions controls have to be from your year car or newer,meaning you can use an obd1 H22 as long as you have OBD2 emission controls on it..

 

i have a h22 sh swap in my 99 accord the car runs but just to get in and out of the garage to work on what are some of the problems with this swap like do i need to get some kind of piggy back system for the ecu?

 

your probably right but the rsx has 140ish torque as to h22's 160ish torque ... i dont know the weight numbers but i doubt its that much lighter than a CG ... i think it would come down to the "better driver" ... omg no i wouldnt even step to an evo before i throw in serious mods into the h22 ... if that was the case i'd borrow my brothers camaro for that lol ... im not worried about emissions any longer, my plans for my car will make emissions unpassable anyway
