I'm looking for a 930S, 87-89. How come regular 911's prior to '89 came with 5 speeds but on a 930 5 speeds did not come availble until year '89? Something to do with being a Turbo?
Of course, I would prefer a 5 speed, but can be happy with a 4 speed in a '87 or '88..depends what comes up for sale first....

Improvements to the turbo have always lagged behind the N/A versions. The 3.2 Carrera received the G50 update in 1987 and the turbo followed in 1989. The turbo gearbox G50/50 has a larger ring and pinion to handle the updated power of the turbo, so it wasn't a drop in from the Carrera. Don't forget that Porsche was entering a period of slow growth.

Does the 89 930 with the G50/50 still have torsion bars? And would a stock G50/50 out of an 89 car just drop straight into any 930 without any modification? Last but not least, is there anywhere that someone can buy one?

Heavy and costly mods to the box are required just to get a G50 into the 88 and earlier Turbos.

thanks for the quick comments. I have an '02 996, 6 speed, so I am totally spoiled with 6 gears. However, I do have a 4 speed Chevelle that I love driving for the sheer "experience," even though it winds up pretty high on the freeway.
As a newbie to 930S', would I be that disappointed with a 4 speed '87-'88? Of course, limiting myself to just model year '89 930S is going narrow my selection of cars out there.... and I sense that 5 speed '89's are noticeably more expensive than 4-speeds (could be my imagination though)
Newbie question #1: what is G50/50 vs. G50?
Newbie question #2: so the N/A versions pre-'89 had 5 speeds available due to the engine output vs. turbo outputs? Pre-89 930 5 speed trannys were not developed to handle the additional horsepower?
Thanks.

The G50/50 has a larger ring and pinion, but the same smaller differential that the G50 5spds all had.
Yes, Porsche upgraded the G50/02 to the G50/50 which is stronger for the turbo application. The gears are interchangable between the boxes though.

As for your Chevelle.... muscle cars are big fun with a 4spd. I always preferred a cruising gear in mine..say a 3.90 or 3.73 The 3.90 is a compromise if you really want to smooth it out, do the 3.73.

Don't think you'll be disappointed at highway speeds and you'll just love 2nd and 3rd while onboost!
Newbie question #1: what is G50/50 vs. G50? Think Jeoffrey got you covered on G50 vs. 50/50...
Newbie question #2: so the N/A versions pre-'89 had 5 speeds available due to the engine output vs. turbo outputs? Not exactly... Development for the Turbo has always lagged behind as it was not viewed as a primary market. N/A cars have had 5 spd trannys since the 70's (915 box). In 87 they got the much upgraded G50 along with a Hydraulic clutch. The Turbos were 4spd from 76 through 88 with a change in 4sp trans (short bell housing to longer) begining with the 78 model yr. Pre-89 930 5 speed trannys were not developed to handle the additional horsepower? There are no "Pre-89 930 5 speed trannys"
Thanks.

Fortunately, I'm a sort of newbie to the 930 as well. I bought mine last February and absolutely love the car. And yes, it has the 4 speed box. Not sure why some folks make it appear as though driving a 4 speed is much like having cooties or a third eye, but I absolutely love driving it. And I'm sure there are others who love their 4 speeds just as I do...If I were you I would try and experience driving both cars and then base your decision on what you like and not someone elses opinion.
Good luck with your search...

I have a G50/01 in my 930 and the engine does not appear to be any further back than the engine in my 1984 3.2 carrera that has the stock 915 tranny.
I presume my G50/01 has been shortened at the bellhousing. This is possible by replacing the rubber centred clutch with a spring centred clutch.

I understand, however for me, I personally would not even think about spending the time effort and dollars to convert to a G50. Not that there is anything at all wrong with the conversion... the 4sp does me just fine, and with the other cars I have, there is always somewhere better to spend the money..
