the ca like the article said wasnt produced as much as the sr.. its a great motor.. low displacement.. thats the only downfall.. in my opinion ka-t is the way to go in 240s.. then i like the ca just for low cost of swap.. then sr.. mainly because ka-t is CHEAP and easy build and if you build right it can be fast and if you put the same money into turbocharging a ka that you do for sr swap it can be made faster.. and a ca swap is extremely cheap compared to both of them.. iron block is amazing for holding power.. i dont know much about the rest of the motor tho.. its a good swap if your looking for that kind of thing
