Very sweet. I see these swaps are becoming more popular as these cars become cheaper. Kinda like a modern day AC Cobra. Little car, lotsa motor. Keep us posted.

dang, what's that thing weigh in at? you've got -what- 440 hp at the flywheel? by my calculations, it should be around 3ooo lbs, which seems a little heavy to miata n00b. maybe i'm wrong though.
by the way, what's with the cops on your street? (kidding)

Ah. I figured on 25% hp loss through the drivetrain, but it looks more like 20%. My virtual engine calculator spit out 3ooo lbs for a 116 mph trap speed. Of course, the ET looks a little high for the speed. Probably had some tire spin judging by that 60' and high speed compared to the ET - I'm sure you could get it into the 11.50s. Great .083 light though!
