ehhh...I dunno where you heard that from...they have made turbo kits for awhile. http://store.crawfordperformance.com/store/products/18
now he's gonna come back and say that "traditionally" meant that they didn't back in the day when he had his Subaru...before he moved.
I am curious what engine management they are using. They claim it can use E85 and does on the fly map switching.
