Of course you just
had to take a personal attack. Couldn't keep it technical, could you?
I have no hatred for P parts. My own car rides on Fuchs, original Porsche wheel locks, Porsche rear disc brakes, and has a late 944 steering wheel. My rear shocks also originated at the Porsche factory. One day when I get around to it, the 924 stub axles I have will go into my trailing arms. Same goes for the 944 Turbo CV joints in my garage. In fact, I used to own a full set of 911 SC, and 944 parts.
I'm just throwing up an alternative to the enless advice here that you MUST use a Porsche g'box on this forum, even when it is so clearly not the ideal choice, such as in this topic's original question. In fact, I find it very humourous that you can't suggest a Berg 5 on this site without getting the full attack from everyone here. Don't believe me, do a search and try to find any thread where a B5 was suggested and not shot down.
For the original question, I would recommend a 4.37 German 8 bolt R&P, with
3.78
2.25
1.48
1.04
.82
Rebuilt IRS Type 1 ZFs can be had for $900, almost half that of a 901 ZF.
It is possible to build a Berg 5 without doing a rebuild, but as you know, it makes no sense. That is because the normal rebuild parts will set you back less than $100.
You keep quoting your experience in converting your unusually low mileage trans as if it is the norm. It is my experience that 40 year old gearboxes are rarely in fantastic condition. Here's an example of what it costs to rebuild a 901:

I can't believe anyone would want to install a 901 that would grind through the gears. Isn't the whole idea to
improve the driveability?
