you have to understand how much more common the honda fixer uppers are than the 420A and the availability and interchangability of their parts also. YOu can take an integra LS block and put a vtec head on it with a type R intake and it will work like it was made to be. We've already come a long way.. give it some time. I remember when this board first started.. there were only a very few people including myself. It was hard enought to find intake and exhaust for our cars back then. Thomas Kim had the Star Turbosystem prototype on his car. The very first ever made. Guess who's car it's in now... It's mine!!
