spray is expensive but that's for the track and special occasions and to tell the truth who really cares. put out for a turbo kit on a stock engine....eventually you'll break ****.......repair ****.......and you're still out money and you won't be seeing 350 off the turbo on the stock L61 anyway. the 2.2 ain't gonna run on any kind of boost forever so does it really matter how you do it? i'm building upon a race proven engine and i'm only looking to run a measly 350whp on occasion the car will be running 200whp or so daily. my build should be able to handle more then my 350 horsepower goal. again work with me here and ready my plans before you pass judgement.
