Mechanical Pron

More Mechanical Pron... This is 4U-GSE (Toyota), and the FA20D (Subaru), 2.0 Liter, horizontally opposed four cylinder engine. It has chain driven dual overhead cams, direct fuel injection, and port fuel injection. It is a small displacement engine, but it is about as hot as you can make a normally aspirated engine which gives it an aggressive, sporty demeanor. It's horsepower rating is 205 HP at 7000 RPM, and that is a little more than 100 horsepower per liter of engine displacement. The main reason a normally aspirated engine can produce that level of horsepower is high compression, in this case 12.5 to 1. The Bang Boxes in this one are very efficient. Altogether what I am saying is... Lots of fun, especially when you are kicking the tail out...
