What would be your best bet for a replacement? Is there any special place I should try and find one? What's the best possible thing I could swap?

 

Get a JDM h22a, serach http://www.google.com and call some local import shops, check the yellow page's or something.

 

search on the boards for h22. check em all out. ht, preludeonline.com, absoluteprelude.com, hpoa.org, honda-acura.net

those are your best bets. i have seen some people get lucky and get long blocks for as little as $800

 

So to just to make sure, any h22a will fit a SH?

No. If you want to keep your SH tranny and ATTS system you can only get another Type-SH motor. Your only other bet is to buy a Prelude Type-S motor since it had the ATTS system as well.

Bascially the SH block casting is different.

 

Alright. Thanks guys. So basically now it's time to hunt down a h22a4.

the H22a4 came in all 5th gen preludes. make SURE it came from an SH for it to all fit up correctly. otherwise you will need the tranny, axles and ECU as well. so just make sure it is from an SH

 

And from the searches I've been running it looks like I'm going to have a difficult time finding an SH engine. Luckilly I'm just planning ahead so far. I don't need the new engine YET, but I know the engine will go sooner or later.

Limited slip differential is main difference, as compared to the ATTS in the type s/sh. This includes EVeRYTHING, for $4,200, if I could, I would go back in time and just get this and be done with it. Instead I chose to fix/build my hydro'ed SH block which is geting to be just as expensive, if not more, AND I'M still stuck with ATTS. bleh. ..... think about it, good luck!

satan or anyone who knows: typeS computer is different or same compared to SH? thanks!

 

i would get a h23 block with a h22 head so u could have all of that low end torque

that still wouldn't bolt to an SH tranny...

 

since you have an SH. I heard you can't swap a usdm or jdm h22a4 in that car. Someone told me you have to get another SH motor or so for the SH car. My my motor got messed up, I was thinkin of gettin a jdm h22a but the person said I couldn't and I have to get another SH motor. Is that true???

 

^^for USDM type SH you can put either another SH motor, or get a TypeS from japan to retain ATTS. If not, any h22 can fit, just make sure it has tranny with it, possibly ecu too, not sure.

Look in in essential prelude links for all the motor decriptions by Satan.

Forget about ATTS, get the euro R with axles, LSD tranny, ECU for 4,200.

 

I have the exact same problem: blown 97 SH. my choices as I understand them are as follows:

1. Replace it with a h22a4 from an SH only
2. Replace it with a h22a and either fab or replace the Trans (and lose ATTS)
2. Replace it with a Type S motor from Japan but mke sure to have ECU
3. Replace it with any JDM engine but include tranny and at the lose of ATTS.

ANY OTHER CHOICES LET ME KNOW!!!

Few questions... If I do option number three would that tranny includes LSD? In other words it wouldn't matter that much that I lost the ATTS... as far as i understand, cux i would get LSD. One more Q. if some guy with a base prelude swapped out for a Type S and also put in the ATTS box, is there any way he would get ATTS? Or would he have to replace the steering coils and just about everything too?

^^NO, JDM's do NOT have LSD EXCEPT for the euro-r tranny. http://www.jhpusa.com/catalog/...id=61

and that last question regarding base to S, I think ATTS is activated as long as they have the tranny and engine from typeS, ecu hooked up, axles . Wait, aren't there any more sensors somewhere?

One question about that. How easy is it to pass smog, legally?

My buddy was saying that getting JDM's weren't worth it because you're either going to have to put a lot more time/money into getting it smoggable, or you'll have to find a shop that will pass you if you slip em a little bit extra.

 

Anybody? I'm really interested in the Euro R swap now, but the whole smog issue is the only thing holding me back at this point.

huh there are several JDM h22a motors that offer LSD transmissions..

Anways you can buy a regular H22a longblock, fab the intermediate shaft and keep your atts if you're ambitious

 

^^isn't the oil filter in the way? How about mounting bolt locations for ATTS unit?

I didn't know about the other LSD trannys, i guess I gotta go look at your thread.

Anyway, I don't think you'll have a problem with emissions.

 

oh ok, looked at your "Blue/Red Top" post in essential links... the euroR is the best JDM trans with LSD out there, with the best gear ratio's/spacing.

damn, wish I knew all this couple months ago...

JuJu, good luck!

 

Alright... I really need to know what my options are here and I am finally starting to figure them out. Just some questions. I am looking at a JDM engine right now... what problems am I going to have with my tranny previously hooked up to the h22a4 from an SH? Cuz swapping in for an S motor like i really want to to keep the ATTS is just too expensive for me, and I CANNOT find a h22a4 that i could buy... the only one i found that had already been sold had 80k miles on it, and was 200 dollars less than a JDM with 15k. ATTS is not worth that much to me. Well... I just really need to know about tranny hookups now that I know which engines work with SH and what not. If i have to buy a new trans for a JDM then i guess it would be worth it... Also am i going to have the same problems hooking up a H22a as I would a JDM H22a? Thanks

 

All H22As work with the SH, you'll need to get a new ECU and the correct drive shafts though. Problems hooking up the H22A? Please describe.

 

Will the H22a and or JDM H22a hook up to my transmission that was hooked up to the h22a4 with no problems? I dont even care about the ATTS anymore because I cant find an H22a4, and if I did it might not be worth buying... and the Type S motor is way to expensive for me.

And also I just have the trans from the h22a4... if I hook up a engine that can have LSD I still need the euro R or a JDM trans that has LSD right? (prob a dumb q)

 

nope the SH block is different from the base block. Either you have to buy the Type-S engine or buy a complete H22A and tranny set.

nope, you can run aftermarket LSDs like quaife, kaaz, cusco in the H22A trannies.

 

Well I have heard three things now. That you cant put that engine on that tranny... that you can put it in that tranny you just have to do a lot of fab work and its really hard, and that you can put it on and that its really easy with a little work.

Assuming that that tranny is easy to put on... I just found this motor for a great price. Anyone tell me what the BB4 means? cause i haven't heard that term in all my research... This is the item description:

"JDM Honda H22a VTEC engine from JDM BB4 Prelude. engine only, no trans. distributor cap is broken, very cheap to replace...... used item, as-is. prefer local pick up......"
