what should I expect from the greddy.....

[Racing Rice]

The engine I named out is for the VX which as a little less power then the EX and SI model in the 5th Gen (92-95) have these motor/specs:

D16Z6 - 1590cc
4 cyl, 16 valve
SOHC VTEC
9.2:1 c.r.
PGM-FI (MPFI)
125 bhp (to the flywheel) @ 6600 (just over 100 to the ground.)
Redline: 7200 rpm 106 lb-ft (to the Flywheel) @ 5200

With a Greddy turbo at about the stock 5.5 lbs of boost that comes preset on the kit, your civic will probably put out 135-150 (to the ground). Depending on what else you have done with it, and if you decide to turn the boost up a little more you could have more power to the ground, I think about 140 hp to the ground is about average, but it really varies from car to car. This doesnt sound like a whole lot of power but keep in mind that thats with not many other mods, in a pretty light car. This will probably put you low 15's high 14's pretty easy.
