h22a type s install - Honda Prelude Forum

rentien · 11-20-2003, 03:03 AM

alright so at the end of the school year i am going to buy a 95 vtec prelude off my cousin, it has 180k miles on it so the engine needs to be replaced no matter what... i was thinking of the jdm h22a type-s so i could have a small edge over other prelude's, integra's, and rsx's out there, it seems like no one likes to drop this engine cause i dont' find maybe threads or postings about it, i find some where peopel post a couple messages but then they dont' post anymore so here i go, yes i have found it for 4200-4600 with lsd transmission and all that, and it is very much more expensive then just a jdm h22a, but i wanted to have a little more power without taking the engine apart and losing reliability becuase i'm quite a lazy person so after this car stuff gets done i don't want to mess with it that much anymore, i just want to be done, i dont' wanna be a car addict to keeps slowely adding things to their car and end up spending so much on it total even though i am planning to spend a lot... i just want it all done at once and be done with exceptions if i am low on money... anyways so if anyone has any suggestions on getting just a normal jdm h22a and getting the hp so the total hp of the engine alone before i/h/e is around 220 i am up for those suggestions, but i really care about reliability, anyways i talked to a mechanic today and he said that the h22a type-s can run fine on 91 premium fuel from the united states opposed to the 93 octane rated gas they use in japan, i just want to make sure other people have heard this too? i really wish i could talk to someone who has done this swap... i can't seem to find too many though, anyways does anyone know exactly what is different between the h22a type-s and the jdm h22a, i knwo the compression ratio of the s is 11.0, but what did they do to change this? and would those changes make it harder to find parts if some were to break? if so i might reconsider buying the engine all together because as i said i would like to avoid problems, and does anyone know exactly what i need to get on top of the engine, as in when i get it shipped to the shop that is going to install it i am going to need to buy new hoses, whatever whatever etc., i dont' exactly know what i need to buy so if anyone knows exactly what i need to buy that would be very much appreciated... and i know this has been a long entry... anything else... if anyone thinks of any other info for me to knwo that would be greatly appreciated too... um... alright o yea i heard on the jdm h22a you have to change the distributor and maybe the ecu for the USDM ones, is that because of the change from 93 to 91 gas? because if so maybe the same problem will carry over to the type s?

i heard people think installing the type s is stupid is that why like no one's responding to my thread haha

I could be wrong but I think the type-s engine had an ATTS transmission and to get it into the 4gen (or even non atts 5gen) would take a lot of work to make everything fit ...

as well the top of the engine (header) and intake etc is different.. I dont know if there would be clearance issues ..

to answer the question about what made the type-s engine 11:1 CR the type-s engine has type-s pistons which are bigger than the h22 that increase the compression. I think theres also a different valves...

get a jdm h22a with lsd, throw in some type-s pistons, maybe get some better cams.. stage2 if your going all motor (you said reliability) get a v-afc and get it tuned then call it a day.

and hey, if i put any wrong info here im sure SOMEBODY will correct my ass ....

check out the n/a forum as well and see other peoples buildups off the H22

rentien · 11-20-2003, 02:08 PM

i thought in regards to the fitting of the engine it should be the same as the jdm h22a... so i wouldn't have to bother with the fitting o yea and this one doens't have atts, like when i'm buying it, it says it comes with lsd so if that would help the fit?

preluda92 · 11-20-2003, 02:15 PM

The Type-S is just an H22 block and head with a better intake tract, TB, IM, more agressive cams, upgraded vavletrain, higher compression pistons, and a better header/exhuast system. The motor itself should bolt right in, it uses the same wiring harness I'm not sure if the ECU is different. The oil pan has better baffling but, it's supose to be the same size. The only problem you may/should run into is the fact that the tranny is drastically different. I've heard that as long as you use a non-ATTS tranny that the motor will bolt on and slide right in. But, I've also hear the motor will only bolt up to an ATTS transmission. So.... good luck.

Any and all bolt-ons you want will bolt up to it. SO long as they are designed for an H22

Zimmlude · 11-20-2003, 02:42 PM

The Type-S motor is out of a 5th gen Type-S. It has ATTS (not LSD). The block is basically the same as the 5th gen SH block. A standard tranny (ie. non-ATTS) won't bolt up to the type-S block. The main problem is that instead of a halfshaft to the driverside axel it has a neat little box of clutches to "Actively Transfer Torque".

Like they said, you would be better off getting a JDM H22A with a LSD tranny and building up the internals with type-S parts. In the end it will be cheaper.

buy H22 dummy!

rentien · 11-20-2003, 05:04 PM

so does anyone know what i could do to get to 220 before i/h/e for just a jdm h22a? and does anyone know what the peripherals around the engine are that i need to buy for the engine drop type-s or not?

rentien · 11-20-2003, 05:06 PM

and would it be cheaper to biuld the engine up? it's 2-2.2g's more for the type-s, o yea and are type-s replacement parts hard to find? i was hoping i wouldn't have to build an engine up cause that might mess with reliability so that would be why i would try to get type s instead cause it's been manufactured so i wouldn't have to get it touched or taken apart

jsmooney · 11-20-2003, 05:55 PM

hell yeah it would be hella cheaper to get 220 before i/h/e with the valvetrain, cams, and pistons, hell you could prob even get a port&polish AND bore the motor and get v-afc for 2-2.5g's more

4thGenReady2Go · 11-20-2003, 08:29 PM

but if you still don't think you want to build, and just buy as you first posted, then the engine you're looking for is the Euro-R H22, just like the type-s (220hp, same compression) only it mates to a mech. LSD transmission, not ATTS. It'll run around the same price, and whomever you found to sell the Type-S for the price you mentioned should also be able to get a Euro-R, if not, there are places out there. Unlike the Type-S, the Euro-R will swap into your 4g without any complications.

rentien · 11-20-2003, 09:00 PM

i swear the website i was looking at said i get to pick between atts and lsd on it... i'll give a link, and yes it's not expensive i think i even found better but i forgot where the other website was... http://www.allbodykits.com/JDM_Engines.htm

that would be great i would love if that was possible...

4thGenReady2Go · 11-20-2003, 09:50 PM

Well I didn't see anywhere on the site where it says you can choose. It says LSD for the Type-S, but they really mean ATTS, if you can find some pics of the Prelude Type-S, you'll see ATTS badges on the front grille and rear deck lid, so they just are a bit confused, and probably assume that ATTS is the same... it's not. I've received a price better than 4600 for Euro-R with LSD,

JDM Wholesale sells both the Type-S and Euro-R @ $4200

and I remember

JDM Honda Parts giving me a price on the Euro-R which was better than 4600 , just click on "Engine Packages", then "Engines We Stock" It'll say sold out, but they told me they could get me one... lol, I was just curious, I only wish I had that kind of money.

rentien · 11-21-2003, 07:08 PM

so people keep telling me not to do this... besides the cost, does anyone know what the disadvantages are of getting this engine, would it be less reliable? would i have a hard time finding parts?

4thGenReady2Go · 11-21-2003, 08:15 PM

well, besides the aforementioned parts that make the type-s/euro-r better than the jdm h22, the other parts shouldn't be too hard to find, or too expensive. One thing to keep in mind is the distributer, which applies to all JDM cars. It is internal, as opposed to our USDM external coil, so I don't know how that works exactly as far as parts goes, ludeboom told me that it's been known to cause problems, what people do after the problem is caused I don't know, but it's not as if the type-s/euro-r are the only jdm engines with the internal coil. Hey, if you have the money, and you're pretty adamant that you don't want to be tinkering around with the engine, go for it. A lot of the people on here who are pretty mechanically inclined may have a hard time with the idea that it's not always as easy for some as it may be for them. Food for thought.

rentien · 11-21-2003, 08:37 PM

yea i was just going to ask a question because people with jdm h22a's have to change the distributor and ecu? why do they change the ecu to usdm ecu is it to be able to take 91 gas instead of 93? and if i were supposed to change the ecu... well there aren't usdm euro R's so... what am i supposed to do, or is it just the distributor cause in that case i have a new one on the bad engine that's on the prelude now... o yea and thanx a lot for your information so far 4thgenready2go you've helped a lot, i never even though of the euro R before...

4thGenReady2Go · 11-21-2003, 09:34 PM

The ecu change has nothing to do with the gas. Most people doing the swap are going from non-VTEC to VTEC, and there are necessary pinouts on the ecu for the VTEC to operate, such as oil-pressure (sensor?) and VTEC solenoid, which "triggers" the cam lobe change. I'm not sure exactly how the distrubutor thing works, someone explained it to me but I've forgotten already, all that I know is that there is a way, and it has been done (basically for all the people who have done jdm h22 swaps). I'm not even sure if it's necessary to swap the ecu, I believe it is possible to add the pinouts for VTEC engagement, but I'm not authoritative source on that. Search the 4th gen forum, you will no doubt find plenty of information on that topic.

94lude · 11-21-2003, 10:13 PM

I would just personally go for a complete rebuild if the mileage really concerns you. Replace all valves, seals, piston rings.... etc...

The H22s is pretti much bullet proof in stock form. I wouldn't even bother with the Type S cams and such... I never really saw any impressive numbers from the upgrade. Also seems to add more wear and tear on the rest of the system. It completely throws the balance of the engine off.

You're talking to a person that had 260K miles on his original engine and tranny on the H22 before it was sold. I would leave all internals stock on the H22... can't go wrong with stock in my opinion. Just get the basic bolts ons... I had intake, header, exhaust, bored throttle body.

Just my 2 cents

damn, 260k miles... that's insane, especially for a VTEC.
