This is why I plan on a slight rebuild of the KA to make it not only run better but it would allow me to use a turbo setup. The plan at the moment is to gain around 200-250hp N/A and start working out a turbo system. I am debating still between this and an SR20. you’ll put more money into making a 250hp n/a ka then you would a 300hp KA-T. N/A isnt really worth it unless you need the instant throttle responce without the lag. plus to build an n/a engine you want a higher c/r where as with a turbo motor a lower c/r is more desirable for reliablity. --- _[View the full topic](https://forums.speedlife.net/t/official-sr-vs-ka-vs-ca-vs-rb-vs-vq-vs-lsx/88991)._
