thanks KE70kid.....7shades is right..the ke70 already has an ca18 in and it would be easier to swap in an SR....soo I'm sticking with swappin in a gearbox to the CA18 or taking that out and putting in an SR...gonna talk to my mechanic this weekend....if i swap an RB20DE(T) gearbox with the CA18DE,can't i just swap in either an CA18DET or SR20DE(T) engine only (later on though) since the RB20 can handle the torque??
