never turbo'd. I did have a kit for it, had fabrication done to ic piping so it would fit and all, but i did all that because i planned to rebuild the motor and boost down the road( i used to have a legit ka-t and it was fun as hell) But all the bitch work is done to the car so sometime someone can boost it, (oil pan tapped, and battery in trunk. Would love to have sold within the next couple of days, found my next car.
