Wanting to take an SH prelude and swap a non SH tranny into it... what all do i need to complete this?

Tranny
ECU?

 

you need an adapter plate so you can bolt a base intermediate shaft to the SH block.

you also need the base intermediate shaft. I am not sure you might need the axles also.

The adapter someone on the bored makes. I always forget his name though.

 

engine, axles (depending on year) I think 4gen have different spines. I'm also looking in this. also need axle bar ( ATTS takes the place of this) and the bearing. Its not an easy swap as you might think its also expensive.

 

the intermediate shaft can be fabbed up using a base intermediete shaft and welding a simple plate to it and drilling holes through the plate i have this setup and ill see if i can get the pics off my buddies cmputer.

 

why not just get a factory inter shaft and bearing? where does the hanger bolt to?

 

why do you say engine??

 

a base or any other h22 trans will not bolt directly to it you need an adapter or a non sh motor.

 

sounds good thanks...

 

I just did this conversion over the weekend. Parts needed:

Intermidate Shaft(AKA half shaft)
Base axles
BASE tranny(i used M2B4)
Steel template( 4'' wide by 1/4'' thick) can purchase at lowes.
Also need 14mm studs and bolts.

Its not that hard to do the conversion, just fabing the plate is a pain.

 

Iv'e been looking for some pics for this conversion on how it looks the adapter plate when installed. I know I saw it before but I can't find it anymore.

 

What are the numbers on the H22 sh? I need to know if my head is an sh.

 

Don't think the SH head is a different part # you can check here but I thought all H22 heads were the same.

the sh motor will bolt to a non sh trans no adapter needed, i think you can eneven keep your sh trans just remove the atts and replace it with intermediate shaft, and buy base axles

 

The adapter plate everyone is talking about is for the intermediate shaft to mount to the sh block.


PirateMcFred makes them so if you don't want to fabricate it contact him.

Really? I thought you need a base tranny to this conversion? I know HT covered this topic with some pics and i just could not find it. That would be good if this is true, this saves money a lot. I've been trying to convert mine so that i can ran p28, but thinking about buying used tranny is kinda expensive.

I would be glad if someone has a complete and correct list of this conversion.

 

You can run the P28 w/ the ATTS, it should just shut off and run as an open diff. It'll be extra weight and you'll need to swap it later to run an LSD, but if you're just looking to tune you don't need to swap your tranny.

Then you can have a mechanically funcitonal car.

If you have an SH swap that you're trying to put into a Civic then an adapter plate, a base transmission and an intermediate shaft is all you need to emulate a standard H22 swap.</TD></TR></TABLE>

 

thanks for the help guys
