Is this possible? If so does anyone have any more information that I can use to do this swap. Ive read so far that I need a base H22 tranny and I have to remove the ATTS unit. I was just wondering if there was any other way to do it or if after all that work would it be similar to a base H22?

 

Look i hate being an ***, but i just typed in <U>h22 into a 90 accord</U> and got 955 results,

please use the search.

 

Well not to be a smart ***, but how many of them returned anything on the SH engine and tranny?

 

Why not just do one and find out

I believe this thread will help you out

While I did find that with a relatively quick search you guys need to lighten up.

And you want him to look through all of them?

 

Thanks.

I did search through the topics with h22 in 90 accord. Searched through around 5 pages and came up with nothing on the SH engine and tranny.

PS: Theirs = There's

As far as the swap is concerned, there isn't a major difference between an SH engine and tranny, and a non-Sh. It is a pretty easy swap and there is an abudnance of information about it on this site.

In fact, there is a guy in Northern VA that is doing one in a couple of weeks, hook up with him and you can see how its done.

Copied from this thread:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by honda-tech members &raquo;</TD></TR><TR><TD CLASS="quote">The SH has a different block, it's a fact. That's why the SH and Base trannies is not a bolt on swap. Internally they are the same, but the block design on the outside is differnt. Intermediate shaft and tranny mounting, oil filter and a bunch of other stuff.

There is a thread on PO.com that details how to do a SH tranny swap to a base, it's not easy and involves fabrication.


The swap to a base tranny is NOT DIFFICULT. Trust me, I've done it...they are my pictures on preludeonline. The _only_ difference is the SH block has mounting points for the ATTS unit instead of an intermediate shaft. The modification to bolt an intermediate shaft up only takes a little bit of work to the bearing carrier of the shaft as well as the fabrication of an adapter plate (which is simply a drilled piece of 1/4" plate). You can retain your SH axles and nothing else changes...you only need a base tranny and intermediate shaft. My pics are here:

You guys also need to keep in mind that, power-wise, the engines are the same between the base and SH models.

 

I know that there are differences between an SH and base setup. However, these differences will not cause a major problem in the swap that he is considering.

Did you read everything I quoted? It mentions what is necessary to bolt a base tranny to an SH block. It may not be a problem to you, but for the OP it might be a different story since there is some fabrication involved, even if it is a relatively simple fab.

And the reason I mention that the engines are the same in regards to power, is that I'm hinting at the fact that it would just be easier to buy a base H22 and tranny. The only benefit of the SH model is the ATTS, and he's going to be throwing it out.

Understand what I'm getting at?

 

My mistake. I misread the original post. I thought he was swapping an SH engine and tranny. If he was, he wouldn't have any major problems. Since that isn't the case, he is going to run into some problems. My apologies.

Dude u went out like a bitch, just kidding

P.S. I KNOW THAT GUY!!!.

 

Apologies aren't necessary. I was just making sure we're on the same page.

 

You are right. I just totaled my 01 Prelude SH and the engine is fine. I was going to swap that into the accord. I wasnt sure if the ATTS was going to get in the way of the swap, or if all the articles Ive been reading could work for both the base and SH engine.

" The only H22 to avoid is from the Type SH Prelude. The brilliant torque distribution system (an electronically controlled box of clutches bolted to the block that Honda calls ATTS) replaces the intermediate shaft and its mounting bracket. The engine and transmission code to avoid is H22A4 and M2U4, respectively. Again, when someone actually swaps this in functionally, let us know. "

Read that here:http://www.sportcompactcarweb.com/tech/0311scc_hybrid/

Thats why I asked and wanted to make sure what all was involved, whether it was getting a base tranny and fabracating or just putting it all in and not wiring ATTS.

Thanks for the help so far.
