i have a civc ek hatch with a d15z6, and the gear ratio's are way toooo long.....
my engine has 115bhp as standard and i have got a 4-branch manifold, standard middle box, and s/s back box and induction kit located behind the bumper, i reckon ive got about 125 bhp now, can anyone tell me any different?????

with that power, the car feels underpowered with the long gear ratio's, so i realli need a shorter ratio gearbox, but dont know what car to get one from

is there a gearbox that is closer ratio, for quicker acceleration.????

If you count mixing-and-matching OEM gears/FD's.....

Si 1-2/ZC 3-4-5/4.4375 FD

Thats pretty much a DOHC ZC with a ZXi FD; except the DOHC ZC 2nd is 1.944 vs. 1.8xx

**thats cable btw***

ZC + 4.90FD + 9000RPM = Yummmmy... And then the motor goes BOOM!

Ah, I miss my old setup, it was a blast on a track but sucked ass at autox...
