I was reading the (Honda Engine swaps, by Aaron Bonk) and the was a paragraph about 1997 Preludes being equipped with the ATTS engine and transmission. Will I be able to keep the Transmission and all the wiring the same if I am going to put a JDM H22A in the car with a conversion harness OBD2 to OBD1(P13) or will I need a complete change over?

 

if the car u have is atts equiped, then you will need a complete changeover. The atts motor and tranny are different than the regualr h22's, you can't mix and match the atts and non atts stuff. Good luck

 

Thanks.

 

Can I use the Head? Because its the transmission that equipped with the ATTS system right?

i'm pretty sure u can, but the atts engine block is different also, the oil filter is in a different spot along with the mounting points for the atts unit on the block, the non atts blocks have 3 holes for the intermediate shaft but the atts unit doesn't use an intermediate shaft, the atts unit takes the place of it. I'm curious, why not just get another atts engine???

 

Also not all 97 preludes have atts, so make sure yours does.

 

How can I tell the difference?

 

I have not been able to find another H22A4.

 

Also check out the crap they gave me in the Prelude forum. My post was
Who is the idiot that thought of the ATTS system?
Thanks for your help.

 

i have a 97 h22a4 without atts.
that was only offered on the premium models.
also what wrong with you engine?

 

Its blown! Rod went threw the front of block.

 

Its a base model, thanks alot for your help. I really appreciate it.

 

you could probably take your h22 atts 1-5 gears and put them in an accord wagon trans, which also has the same 4.2666 final drive
