CA slow??? LOL search before you post something like that. rb is way better then KA and sr…ka wasn’t made to be turbo charged …unless it’s a build up engine…turbo on a stock ka will be good for not more then 6 months. That’s when all the problems begin. if you’re looking for something normal swap an sr. goodluck. --- _[View the full topic](https://forums.speedlife.net/t/engines/135502)._
