I have a guy that brought me a 98 prelude base model car that has a hydro locked engine. He said the new motor he bought was the same motor but he was wrong it is out of a sh model prelude and has a big *** "atts unit" attached to the block. So my main question is can this swap be put in the base prelude or is all the wiring and everything different on the chassis harness of the base. I'm not a prelude genius so i thought id ask you guys. as much info as possible would be nice.

 

Dont do it. The engine wont even fit. the easiest thing would be to get another non sh block.

 

Ya it wont work u need a regular h22 no sh

 

I have the entire swap out of the sh prelude. motor trans ecu. But if its a pain in the *** ill just tell the guy to come get his car or to buy a short block

 

It's basically the opposite of the SH to base swap, so I would think you just need the motor, trans, and intermediate shaft and it should work fine. Obviously the ATTS system won't function, but all of the regular motor sensors and connectors should be exactly the same, so it should bolt up minus the things mentioned.
