Weight

Gear Ratio ? the overall gear ratio of the vehicle, which includes transmission and axle

Drag ? drag coefficient of vehicle

Frontal Area ? frontal area of vehicle

I'll be needing this to setup my Nology PDA-Dyno

You're gonna have to give us more information. 5-door hatches weigh more than 3-door hatches, automatics weigh more than manuals, final drive ratios differ from auto to manual...Do you have the SOHC or DOHC engine?

Anyway, let me take a crack at it.

WEIGHT:

2374LB (add another 33lbs if auto)

GEAR RATIOS:
FINAL DRIVE: 3.72:1 (auto 3.19:1)
5TH GEAR: 0.89:1 (auto, 4TH GEAR 0.68:1)

DRAG COEFFICIENT:

I couldn't find this value but I would guess a value of 0.32 would be a fair assumption.

FRONTAL AREA:

I couldn't find this info either but it can be calculated fairly accurately:
FORMULA:
(Height x Width) x 80%
(56.3 x 66.1) x 80/100
~2977ci

You can toy with these values until more help arrives.[/b]
