The thing is with engine changes, more cubes or killowasps are not always (rarely) the best way to go. A couple of years ago I saw a Mk1 Escort at an autocross with a huge turbo bolted on the side of pinto. Off boost it was a dog, it would spool up and the car would light up the wheels uncontrollably with the driver fighting to keep the car straight..... Very entertaining to watch[88][88][88], didn't look like the driver was having too much fun though.
