Gear swap..

[86pony]

Hey guys..
I have a 2000 GT 5spd i am going to do a gear swap on..
Have searched through the postings on this, and the prevailing theory seems to be that the 4.10s are the best way to go.
first question is, how much more rpm will i be turning compared to the factory gear set at lets say 50mph...
question 2...since the rear end is going to be opened up, would it be worth re building the traction loc setup at the same time..
The car has about 50.000 miles on it and has not been used hard, and as far as i know, it seems to be functioning correctly, but i do not know what the general lifespan is of this setup is, so if the milage dictates that it is getting near the end of its days, it would be better to do it while swapping the gears.
Thanks for any imput...

4th gear @ 50
~2200 rpm with 3.27 gear
~2500 rpm with 3.73 gear
~2700 rpm with 4.10 gear
It's probably worth it to rebuild your trac-loc while you have it out, especially since parts are only about $40 or so. But mine is still going strong at 75k.

Thanks for the input 1989GT..
Since my car is a 5spd, i will assume that it will be turning less than 2700 rpm in 5th, which is good because i do quite a bit of hwy driving in the summer months, but the 4.10s should work out ok.. Think i will go ahead and re build the trac loc, then it should be good for another 5yrs...

Hey all, I just talked to one of the guys at my local performance shop about the gears for my 04 GT and he said that at 80 mph, I'd be at almost 3K with 4.10's. It seems like a lot especially how gas prices are going..
They have a special where you get your choice of gears and an ACT tuner(incl. 1 tune)for $569 + $260 labor. I was debating this over an exhaust since my intake is done and I can tell that the car needs to exhale a little better. In your opinions is that too pricey?

But my real question is about the Clutch. Would a stock clutch have any issues handling 4.10's?
Also, 4.10's and 4.56 for that matter seem like a great idea for drag racing, but how bout road racing? I intend to start taking my pony to the track so I want to make a good decision.

Thanks ahead of time for the advice...

hey narshadda, i replied to a thread you started a while back and i rambled on about gears, only to read this right after. d'oh. to be honest: as soon as i put my 3.73's in, my clutch started making a whine noise when i would release the clutch pedal. then again, my car has 80+ k on the clock, so it might have been time to swap any way. see my post "vibration at 3k" regarding my clutch problems. new clutch whines exactly the way the old one did, does feel like it has a positive engagement though, snaps the neck! i've got another 50 miles on the centerforce directed break-in period on the new clutch. then, i will romp on it hard, and see if everything is OK.. but right now, feels like vibration from clutch is hindering car's performance. before the clutch swap, post gear swap, the car was a freakin' beast. hope to help, shoot me back if you want for more advise. stay cool man

Hey Mark, thanks again for the advice.
I know that Gears are a great upgrade but I can see how other upgrades should be done with it. ie. Clutch, SpeedCal/Tuner etc... So If I do this right, I know I will be spending around a grand in South Florida. THings have a tendency of being more expensive down here.
