I want to up the compression on the KA24DE, and I hear to get it up to 11.1:1 you can use KA24E pistons. I know ITM sells them including the rings, pins and locks for around $150. What I want to know is will they fit right in a DE block or is there any boring or anything else needed? Thanks in advance, all input is appreciated.

 

The drop right in.

 

hey artic i asked the same question didn't i??? im getting all my parts next week so i will be doing a full write up on the bottem end rebuild... with the sohc pistons... new crank and bearings... will be taking pics of everything so i can keep everyone informed on how it goes... the parts for the head are going to be here soon as well... the plan is to do a full write up of everything i do to the motor and dyno results after it is all done... we will see what we can get out of a na ka24de motor...

 

Alright wikd let me know how everything goes, Im preparing to do a whole new bottom end and put in some PDM cams, I'll write up and take pictures of the cam swap.

 

Be sure to use at least 91 octane from now on.
