(a brief word from our sponsor)
Please fill out your profile[img]images/icons/smile.gif[/img] people look there to learn all sorts of good stuff about you.

I'm sure that you meant 31" tires. If you have 51" ..there are some on this board that want to know how you did it ..and where you found them[img]images/icons/smile.gif[/img]

If you have an automatic:
Save your money for gears.

If you have a stick:

Forget about 5th gear.

There is NO shortcut to horsepower.

How much faster do you want to go then 75 mph? Are your normal driving habits going to require warp speed of a higher order? Admittedly contemporary traffic habits tend to "go as fast as space permits" ..but 75mph seems to be the "normal" ceiling of acceptable highway velocities.

...also ..the 4 banger never came stock with 31" tires fact I don't think a TJ came with anything bigger than the 30" tire package (28.7" in dia.) ...have you changed your speedo gear ..or verified that it is correct? You may in fact be doing faster than you think. You won't go any faster ...but you will feel better about how miserable the thing is performing.

Any true power gains are going to cost you. Forget about the exhaust systems and even the intake thingies unless you want a reusable filter.

Save your money for probably won't go any faster ..but you'll feel better getting there.

Re: My 2.5L

thanks a bunch, and yea i did mean 31" tires sorry about that, its a 5 speed manual, and 2day i experimented a little with my clutch-gas habits being this my first manual and i have found an easier way to accelerate faster than what i thought i could, and no the 31" tires are not stock, they were put on by the owner before me, along with some nice american racing rims, thanks for your help
