I have a 00 ZX3 with mods and i want to figure out how much Hp it now has?

Nobody can give a realistic number with an assortment of modifications. Take it to a dyno and find out the HP at the wheels.

i'd say around 145, give or take a few... I have the same engine w/ 4-1 race header and straight piped. Still slow, but fun in the curves :)

I'd say like Patrick said, about 145-150 hp. 136 Hp Cold air 5 Hp Fuel rail 5 Hp Header + cat and exhaust maybe 12 Hp max. I own a 2003 Ford Focus zx5 that produce about 250 horsepowers. Mods: Vortech Supercharger, fuel injectors(42 lbs), headers 4-2- 1, cold air, exhaust and thats about it. Without any engine mods like for examples, comp cams, or forced induction you will stay at 155-160 BIG max. Chip.

Well its a 2.0 dohc with cai, cat back exhaust, supercharged air intake, a mod 1 chip and a crank pully. plus just freshen up head,3 angle valve, slight mill. just don't know what to exspect
