Clyde, I don't know. I'm not interested in hearing about how I'm doing it wrong at every stage
Sorry I wasn't clear but I'm using a Mazda "L" engine, aka Mzr, aka Ford Duratec (designed by Mazda) in the 2.5L displacement. It's a very light aluminum four cylinder with 9.5:1 compression, factory forged crank and pistons, designed from the start for boost. Obviously I'll build it to handle the power I plan to make (around 520 at the crank).
Same basic engine as the Ford ecoboost inlne 4.
