$10,000 may be conservative if you do it right.
Check out gear prices…at G-Box, California Motorsports: New at about $1,000 a gear set…on a 3rd - 5th replacement, you'll need at least three (3) gear, that's $3,000. Some machining is involved to make your present 5th, 6th, $500? We are at $3,500
Steel Synchos at $300 a pop. You'll need at least three…3rd, 4th and 5th. There is another grand….up to $4,400
You should also add forged shifter forks, about $600 for both, 1st 2nd, 3rd-4th. Now up to $5,000.
Since you will be driving the car a little harder, you should add a forged side cover to the tranny, keeps the LSD from moving around. About $350. Now at $5,350
Of course you'll need a Golden Rod and a Factory Short Shifter $500? Now at $5,840
Since you will be maxing out performance, you'll need RS tranny mount and two RS motor mounts, $1,000..now $6,850
Figure labor, I understand that $2,000 is pretty typical. Now at $8,850, best case scenario,,,that is, if nothing else needs replacement.
Now there are the while your in there costs…RMS, a clutch, maybe a LWF. And there are misc. bearing that may/will need replacements and the usual gaskets, and misc.
Just as in divorce, you know why it costs so much? Because it's worth it….

I have 2 993, one with stock gear ratio GBox and one with custom: night and day difference!

Funny how all performance threads lead to gearing changes... even when the thread is started by someone w/ a tiptronic. :-)
Since we're on the topic though, can you guys w/ re-geared transmissions comment on relative noise differences between the various gear suppliers (Albins, Guard, other)?
Has anyone used California Motorsports 'weld on' 1st / 2nd gear replacement instead of buying the G50/3x or early -/2x mainshaft?

redlightrisch said.....I have seen some converted to race cars, but I was trying to learn about streetable power upgrades, and what can be done.
forget 993 -- buy a corvette!

Anyone re-geared a 993 turbo box? Is it doable? Worthwhile? I think I can give away 30 mph top end in a heartbeat if I can get to my max sphincter speed of about 150mph a little quicker

Oh my,..........
You need some enlightenment here. This has nothing to do with track events; re-gearing DOES provide torque increases at every RPM & speed due to the lower overall ratios and much reduced splits at each shift. Its just perfect for those country roads!!! The only difference between track & road use are the specific ratios chosen for the job.
My best suggestion is for you to drive a 993 that's been re-geared properly for you feel the experience for yourself. Its a true epiphany!

I understand that lower gears = increased TQ multiplication and greater acceleration capability.
I'm just not sure if the butt dyno experience in "everyday driving" from a re-gear is the same or significantly better as a baseline engine TQ increase.
Excellent advice re trying to get some seat time in a properly modified car to find out.
cheers

It's very difficult and expensive to get meaningful torque increases from the engine, much easier to lighten the car so that the torque you do have has an increased effect or regear to get gearing torque multiplication
here is a healthy 3.6 w/ w a stock /20 compared to a regeared /20 where 1st was kept stock and 5th was moved to 6th
red is regeared, red/blue is kept gears and blue is stock. This could be improvedby eliminating the x over tails where on gears torque continues below the next gears torque, ideally you want the end of a gears useable torque to end where it meets the next gears torque curve, the difference in heaight between each corresponding gear set is the increased push that yoor butt experiences, in this case each is meaningful, you really ought to try to get a ride in a regeared car, it's night and day compared to stock

I let 6-8 guys (and one girl who occasionally competed pro in the old Koni Grand Am series) run the yellow car way back when. Funny thing was when it was street licensed and I offered it up, no takers.
Since the repaired box will likely end up in the 4S at some point, same offer will stand. Might have to show up in Phoenix, though............

I was told by the guy who should know that PMS gears would be less noisy than Guard. Albins did not come up in the discussion.
