ok, can someone explain me why so many ppl convert there engines to, for example a h22a when they dont even go that good in preludes where they originate from. and like top quarter mile times are 14.5 average. Dont get me wrong its quick for a lil 4cyl but its not that quick. like i have not seen one quick prelude. And if some1 can also tell me what is the best modifications to make the h22a quicker. cheers...
lol.
well h22a has one of largest displacements of any fwd hone engine from the 90's. it also is DOHC vtec and can be coaxed into produceing a bit more power then stock.
The modification u can do to a h22a is 2 turbo charge it
but its gonna cost ya big bucks
put a h22a in a eg and see how fast u will go ;)
how come the guys and galz who have prelude vti-r they go like buckets lol and it has the h22a engine in it
the body of the car weighs a shit load. and lookn at an NA motor the weight of the car is very important
i think it actually makes a difference is u have AUDM h22a or JDM h22a plus, the gear ratios are different between both spec engines. JDM being better in all area's including ecu which is tuned for jap spec fuel but will run fine on optimax/ultimate plus has different fuel maps etc.
I think most AUDM h22a's are 190hp where the JDM h22a of the same age is 200hp.
it think the later model AUDM preludes are 200hp , not sure
ive driven 99 model prelude vti-r with manual tranny and then i drive my JDM h22a in mah accord and i can say my accord is quicker. some JDM h22a's have factory LSD which is handy if u want to take off fast!
oh koool. reason why im asking all of this is because i wouldnt mind building another accord with h22a. so what year engine do i look for at the importing wreckers and how can i tell if it is a jdm engine compared to the ozzi version
also how can i tell which has the lsd. and what will it cost for me to get one including engine 5 speed gear box ecu and the mounts. and when u get the front cut does it come with all the wiring loom
JDM engine will have the engine code H22A, tranny code for LSD is M2B4, if u buy front cut you can also tell if it's JDM just by looking at the stickers in the engine bay etc, they are all in japanese!
The complete wiring loom comes with a front cut but you wont use much of it anyway, you will only need the wiring and sensor connections from a few sensors that are on the H22A that arent on the f22b. The existing accord harness will connect directly up to the H22A, with that said, a couple of the wires need to be lengthened as the same sensors are in different locations on the H22A compared to the f22b.
What you do is disect the wires you need from the front cut ie, from the sensor to the ecu and once you have the extra ones you need, wrap them up in a new loom and feed it back from the engine to the ecu.
You only need one prelude mount to bolt the engine in, you use the 3 other existing accord mounts.
You should look for a 96 model front cut, i think they are fairly common although, i know that towards the end of 96 honda changed from OBD1 to OBD2 so find out what your car is and get a front cut to match.
I put a 6/96 OBD1 engine and ECU in my 94 accord. You will have to find ( for legality reasons ) a front cut the same age or newer than you vehicle.
Apart from the h22a is it possible to place another newer engine in it such as the euro v6 vtec for example or would you be restricted due to engine mounts size etc,
when i buy the front cut does the ecu come with it? and also say i got an accord auto can i still just do the conversion da same or does other stuff need to b changed like i know the pedals but wat else. asking this because accord vti-s do not come out manual.
well not manual with climate control. oh yeah does the abs interfear when doing the conversion.
it shouldnt interfere as abs isnt ecu related. go check out this website and it tells you.

good luck with the convo mate.
uv been a great help h22a accord. thanks heaps. one last question can you tell me roughly how much a H22A with tranny code M2B4 for lsd and the ecu. that comes with the half cut. how much am i looking for a half cut.
thanks again
theres this place in vic
honda wreck, they have H22A imported from japan, they got heaps of it, they just got in 5 jdm prelude all with H22A, and ive asked them about the convertion for my car and they said about $3300 for the complete make over, thats including labour and everything....all u need to do is drive in, wait for them to finish (1 week maybe) than pay them, and thats it
get a h22 type S
$3300,,, if my sohc engine ever dies,,, I'm definitely giong h22a.
infact I wanna get one anyway,, gotta save up!! hehe
is this price for a new one, or second hand engine?
Alan
i found one from this place in nsw, he got accord siR halfcut. Is that the same as prelude. anyone???
same engine but its 195hp instead for 200hp, how much thy selling it??
its an auto he said if i have a manual gearbox i could use mine and leave him the auto he'll do it for 3200. He said since i got an accord its much easier to do the conversion straight out and straight in. he said dont listen to ppl wen the say prelude fit straight in i laughed at him over the fone he got a bit peeed off but yeah he said cross members and wiring and shafts are all diff but yeah.
Oh, where does the extra 5 horsepower come from in the prelude engine????
the type S has 220 hp
which h22a engine is the type s, and will it fit the same as others. what is the difference with the engine to make 20 more hp
its just called an h22a
like the dc2r engines are called b18c
go read the sticky in the prelude forum on h22a type s, it will show what makes the extra 20hp.
the accord h22a is detuned.
if i were you , get eh prelude gearbox along with the whole front cut because the accord ratios are different.
the prelude box is close ratio and will have better acceleration.
www.adelaidejap.com.au are selling used JDM prelude SIR front cut with M2B4 gearbox and p13 ecu for $3500.00 plus shipping.
they are really good, i have no hesitation in recommending them to anyone!
Your mechanic is a dumb shit if he says the h22a will not bolt in there without changing cross member, shafts and wiring. u can use same cross member, accord shafts and intermediate shaft and all of the existing accord wiring loom except for one sensor that dodent come on a h22a engine.
I am not a mechanic and i did the conversion myself.
Sure, the extra wiring you have to add is a bit of a head **** but if anyone runs into trouble let me know and i'll help you out.
u use all accord mounts except for one
hey h22a accord, is it ok if i get the accord sir front cut and tell the dude to swap the accord gearbox for the prelude M2B4, and would the accord sir have the p13 ecu??
Also when u say the accord is detuned what exactly is detuned cant i tune it to be the same.
good luck finding a 2nd hand jdm m2b4 gearbox :) i dont think the accord sir h22a would have a p13 ecu cos its a prelude ecu.
i think the power loss comes down to the different ecu.
lol. well if its just the ecu that is diff i im sure i can find a p13. and then remap it with a mugen chip so it redlines at 9,200 lol but this gear box thing is the only thing annoying me atm lol
hey guys....so with the 5th gen preludes....r all the engines h22a? coz i own a 97 prelude Si, and i was just wondering if its different to the vtec and type s
someone plz help with details
p13 manual will be a bitch to find.. m2b4 is liking finding a needle in a haystack... and wen u find in be prepared to pay big $$$$$$ .. anyways to me h22a is a good all round motor as stock.. it doesn't go that fast in preludes as mentioned b4 from weight.. but put it in a DA, DC, or EG.. hehehe completely different story.. plus h22a is alot cheaper then getting b18c
if its an Si it would be a h23 engine.
and by the way... my VTi-R lude kicked ass over many a turbo car (before i turboed it)
and now it just kicks ass hahahaa:D
is it just h23 or h23a??Quote:
