The guy above me was sort of on the right track. The whole not good for turbo is false. If you BUILD IT RIGHT and don't cut corners like many do. It will be as realiable as any other motor. But if you were going to put a turbo on it later down the road. Then the lsvtec is a waste of time. When you could just port and polish the ls head turbo cams and upgraded valvetrain and you'll be good. But if you do the frank motor make sure it's done right with the right parts and not half assed because he won't last long. Look at lsvtec kits that companies sell the kit and go from there.
