I could provide a dyno sheet, but can't find it right now.  Long story
short, a Mitsubishi "tooner" has been building this 1000HP Evo with 5
inch exhaust, a turbocharger that makes Happersizing look more like a
Happy Meal, dual fuel rails on a sheetmetal manifold with 1000cc
injectors, 2.4L stroker 4G63 Evo motor and an intercooler that
requires partial removal of bumper (Trevorsized?)

Basically, they overdid things to the point where the car makes less
power than a stock Evo anywhere but highRPM (7.5k-8.5k) where it
finally spools and makes 600whp.  Needless to say, they're working on
it to make the powerband a wee bit wider.
