The 993 Carrera for US got longer gears than the European one, is that also true for S/4S versions?

os993

Yes I think so.

timothymoffat

Yes. US and Canadian cars had the longer geared G50/20 from the start of production on all models. ROW cars were blessed with the shorter/closer geared G50/21 through early calendar year 96 I believe then also switched to the G50/20 for the rest of 993 production.

So if I want shorter geared 993 I need buy RoW until early 96? Did early 4S also got shorter G50/21?

God luck by finding another 993 Gearbox, especially a G50/21.
If you do, be prepared to pay a fortune without knowing the conditions of the box.

If you really want to do something, just re-gear your existing box

No - all S and 4S had the /20 gearbox from the factory. I believe all Targas also had the /20 box.

ROW narrow bodied cars, 2wd and 4wd, had the /21 gearbox until they exhausted supply in the factory, sometime around August 1996

(obviously all 4wd cars had the G64, and the 2wd had the G50)

I own a Nov/1997 Carrera S RoW and it has the shorter one. Not sure if good or bad, but I like it

orangecurry

Nahhhhh you don't

You have the G5020-10 gearbox - go and look at your underbonnet sticker, and put up a photo if I'm wrong

I'd tend to agree with @orangecurry but stranger things have happened. The difference is quite significant in the intermediate gears (2-5). From memory the glaring differences below:

G50/21; 4th gear @ 6800rpm: 114(ish)mph
5th gear @ 6800rpm: 141(ish)mph

G50/20: 4th gear @ 6800rpm: 138(ish) mph
5th gear @ 6800rpm: 159(ish) mph

To the best of my knowledge is the short one … I’ll get him a CoA anytime soon and I’ll answer tour question!!!

Out of interest, which one is better? if any is better

I always wanted a regear but just didn't have the money to throw at it when the trans was out. It would definitely be better suited to my frequent trips into the mountains.

jepp, over the thumb about $ 1,000 per gear you want to change, but compared with the insane prices for a full gearbox (if you find one), its still comparable 'inexpensive' ...

When i searched for a gearbox, the cheapest started by $15K, and that was still a G50/20. I decided to put in a 996/7 GT3 box, nearly completely regeared, and still cheaper!!
But also IMHO, that makes only sense if you convert a tipper...

orangecurry

Apologies if I missed your thread on the car - does it not have an underbonnet sticker? Or the same sticker in the Service Booklet?

Cactus

I looked into a regear/rebuild when my trans was out for clutch and all associated parts. I think the cost was going to be $11-12K in addition to all the other stuff.

Sorry for my mistake !!! I was wrong. I got the 20 one following the sticker.

The reason of the mistake is dual: first from my longest trip so fa (400 miles) and downhill, 4th gear the car didn't go faster (compared to a modern Hybrid I use as well), and secondly, I went to the official Porsche garage to chat with a mechanic and he said I might have the short one.

Sorry again and thanks for the learning !!! THANKS
