Matt:  With regard to performance mods and economy, I recently
installed a BBR turbo.  I havn't tried to test 0-60 because I don't
want to possibly damage the clutch. It is much much faster in standing
start but I don't have the numbers. However, I have tested 50-70 mph
in 4th gear and 5 th gear and the car is about 1.4  to 1.5 fold
faster than stock.  What is suprising is that all this increase in
power occurs WITHOUT a decrease in gas mileage which surprised me. In
fact mileage is actually about 4-5% greater than stock. I don't know
the exact reason.  I assume that this occurs because the engine does
not have to rev as much to generate the same power as stock although
the increased power is there when you need it.
