Porsche Gearbox and GB 5-speed

[Toby Erkson <Toby_Erkson@ccm.jf.intel.com>]

Talked with Tim at Gene Berg and here's the scoop on the 5-speed for a '72 
and later Type III -- can't be installed easily like a Bug.  Apparently the 
frame horns are different and there isn't a place to mount the extended 
nose cone.  A special tranny mount must be fabricated.  Previous to Tim I 
spoke with someone else at GB and he had said that there was someone 
putting the fiver in his Fastback and fabricating a mount.  I need to call 
back in a couple of weeks to find out the progress of the T3 mount.

I'm taking an educated guess here (a WAG maybe? [Wild Ass Guess] :) but if 
someone was to put in a 911 (generic term) gearbox some custom fabbing 
would need to be done since it is a bigger box than a stock T3.  And 
Patrick is correct about the 5 reverses and one forward!  Gonna have to 
flop 'em.

For those who don't know, the 911 tranny isn't shifted from the nose cone 
like what we're used to, it's shifter is actually on the side of the tranny 
(a.k.a. a side shifter), which is why the linkage would need to be 
customized as well (Patrick, I can't remember, but did the earlier 
gearboxes have a rear shifter or were they just a different sloppier 
version of the side shifter?).  Also, there is a gear driven speedometer 
output from the tranny, opposite side of the shifter (VWs get speedo info 
from the front left tire, 911s and 914s get it from the tranny).

This type of modification for Beetles has been covered in quite a few tech
articles in many VW mags.  I doubt that an adapter will even be needed, as
certain 911 clutches will work for this application.  The biggest problem
is probably welding in the mounting brackets.  Again, I believe that it
depends on which tranmission you use: 901 or 915.

It should very similar to doing this swap in a Beetle.  Toby was also right
about the linkage.  More welding will have to be done to extend the
linkage.  Some type of modification is also needed so that you don't end up
with 5 reverse gears and 1 forward gear if you take the transmission out of
a 914 (901 gearbox).  This is also explained in the tech articles.

 * I have read the Volksworld article in Sept 1997 issue on installing into the
 * bug and wonder whether there have been any features printed on
doing the same

 * Any help/leads would be greatly appreciated.

I doubt it.  You can probably use most of the info related to doing this
into a Beetle, but in some areas, you will be on your own.

 * P.S.
 * I would like to transplant the 1970cc Type 4 motor from my '80 wedge into my
 * '73 fastback and would like to know what to do regards cooling
tinware/engine
 * mounting bracket

I don't know why you would want to do this, but anyway, the guy that runs
Big Boys Toys in the UK (Paul Howard) has a 1971 FB with a huge TIV engine
in it.  I would ask him - BTW, his car is for sale.

Good luck.
