It's 2500RPM if you have a P185/60-R14 tire.

that doesnt seem right... mine is at 2800.. and takes almost 4qts til it registers correctly on the speedo gear dipstick notch

[bhazard]

2800 is about right with the .8 gear...
About 2300 with the .71 gear from the 626.

[fastivaB6TG25MR]

is that a 5th gear swap?

[bhazard]

Yeah azgtx on teamcapri sells them for $55.

We're both 100% right. I said that's only the case with 185/60-14 tires. With your 215/50-13's, you're right, about 2750RPM.

LOL wow... screw that!

[Damkid]

Ya going down the highway at 120kmh at it's screaming at 4000 rpm :shock:

All the more reason why I want to run escort ZX2 tranny internals to keep the rpm's down lol

You know your car makes too much power when down-gearing your transmission's ratios is the best way to improve traction.

[sasquatch]

and with 2.5L of motor at 4000rpm it must just guzzle the gas.....

It's more about gas mileage, traction isn't toooooo terrible with my car

and with 2.5L of motor at 4000rpm it must just guzzle the gas.....

The best i got with a full tank of gas was approx. 300kms
