meh. awhile. but yes i am "slapping" a turbo on a running ka but im not cutting any corners. and my other KA i have is fucking immaculate. it should last me for quite a while. and once its boosted, i will be taking extreme care of it. plus the highest im pushing it is 10 psi on a t25. but once this ka is in my car and boosted, im gonna build my other KA while im driving this one.
