g50/31 box
does anyone know if a regular C2 box can be converted to a 31 or 32 by changing the gearsets/shafts etc. ?
|
All of the /20 & /21 can have 3-6 changed easily enough, 1 & sometimes 2 are integral w/ the main shaft, the changeover trans #s are
G50.20 - 02693 G50.20 - 02174 (M220) G50.21 - 05072 G50.21 - 03094 (M220) before only 1 is fixed after 1 & 2 are fixed, to change them a new mainshaft is required(last price I saw Was ~$2000, I'me sure it's much more now) The Motorsports boxes, /30 -/33 have loose gears in all positions 1-6 Many choose to leave the main shaft alone and change 3-6 and that works but isn'e really an optimal way to do it. |
thx Bill, can you actually still order a complete 31 or 32 box from Porsche ? They much be huge money if you can ?

/31 is 1 step up from /21 which is a step up from /20 /32 has more good stuff and better gearing /30 has the most good internals and the best gearing but isn't going to be generally available |
I just did this last year. I agree with Bill, better (and actually way more cost effective) to simply sell your old box and buy a g50/31. In addition you also get a Porsche Motorsports LSD. As a bonus, I'm guessing your old box is a g50/21, which will be easy to sell for top $$$.
Here's a link to my impressions of the new gearbox: https://rennlist.com/forums/showthre...ferrerid=21390 Cheers, Joe |
A member on Pelican recently priced one out of Germany. It was more than $12,000 plus shipping. You could build one to that spec for less than that.

Last prices I saw
/32 north of $12k w/ a like exchange /31 $north od $6.5k w/ a like exchange I'm sure that jmarch has better #s [QUOTE]You could build one to that spec for less than that/QUOTE] So could you price one out at current prices w/ new mainshaft, steel syncros, billet forks, billet shift spindle last prices I saw a few years ago was $1950 mainshaft $750 2nd gear set $695 3-6 gear sets $2350 for 40/60 lsd h/d 1/2 shift fork $199 h/d sbillet shift spindle $275bearing kits ~$140 each |

A change of heart Jackal???
I saw your discussion on a P/heads about gear ratios, where you thought the standard ratios were better for your use of the car....Even if it did surprise me. There are always people looking for these, some end up in Ultimas with big power etc.... For some reason the previous owner had the /32 in mine rebuilt at an OPC in 2001, remove, rebuild, refit was £11k!!!.....glad I didn't have to pay that particular bill!!! |
