991 turbo versus 930

Since we are quoting..from page 17 "However the 911 Turbo became such a success that it has been in production for 21 years"
and from Porsche press site...read on..again I repeat no wrong answer to the op's original question.
40 years of the Porsche 911 Turbo
Fast, sporty, comfortable – and unique
In 1973 at the International Motor Show (IAA) in Frankfurt, a silver car was on display that
attracted considerable attention. On its trunk lid was an audacious rear wing perforated
with air slots and framed by a thick rubber lip. The vehicle was reminiscent of the 911
Carrera RS 3.0, which had just come onto the market, but the badges on the rear fenders
made it clear that this was an entirely different model: “Turbo” was the word that would
from that point forward captivate the sports car world.
What lay behind the prominent rear wing gave even veteran Porsche drivers pause: a turbo -
charged 3.0 liter flat-six engine with 260 hp, capable of 250 km/h (155 mph). The Porsche
911 Turbo was thus the fastest German street sports car and triggered newfound enthusiasm
for turbocharged engines.
Though the Turbo was only a prototype, the decision had already been made to bring it to
market the following year. This was a bold move: although turbocharged engines were not
unusual in racing by that point, only one carmaker had attempted turbocharging for a street
car, and failed miserably. Drivability, durability, and linearity had all been turbo shortcomings
in street cars – the turbo engine was considered too wild to be tamed.
The fundamental idea: a race car for the streets
Porsche engineers knew how to solve the shortcomings associated with turbocharged
street engines. A short production run was planned for street legal vehicles derived directly
from motorsports. The GT motorsport regulations of those times prescribed the construc -
tion of 400 units, and Porsche could not sell so many vehicles to race car drivers. There -
fore, it was decided that the racing vehicle would be made street legal with just a few com -
promises in comfort. The turbo engine was specified from the start. Porsche had already
gained experience with turbocharging technology from the twelve-cylinder engines of the
legendary “917/10” and “917/30” race cars with up to 1200 hp. As well, the two-liter,
130 hp 911 engine from 1963 was no longer turbocharged but had enough potential for
further power increases to be victorious in motorsport.
40 years of the Porsche 911 Turbo 17
Porsche overcame some disadvantages of turbocharging by regulating boost pressure via
an exhaust bypass valve, a technique that had only been used in motorsports. This vastly
improved drivability at lower engine speeds, ensuring linear power and torque curves that
avoided surges and gaps in acceleration. As well, this control system increased boost and
torque and low engine speeds. To ensure equally high-performance braking, Porsche called
upon its extensive motorsport experience and installed internally-vented disc brakes with
aluminium brake calipers behind the wheels, which had originally delivered excellent braking
in the Porsche 917 race car.
At first, plans called for 400 units – then 1,000 – of the 911 Turbo 3.0. This was way offtarget
as, by 1977, a total of 2,876 units of the 911 Turbo 3.0 had been built. The car was
luxuriously equipped for the times and included factory-installed electric windows and a
stereo cassette radio.
1977: Porsche Turbo reaches milestone power of 300 hp
When delivery of the Porsche 911 Turbo began in early 1975, no one believed that there
would be demand for even more power. Yet there was, and Porsche obliged in 1977 with
the 911 Turbo 3.3, whose larger engine produced 300 hp and incorporated an intercooler.
This sports car was known as the “930” model and remains a legend. In 1987, a Targa and
a Cabrio joined the Coupe.
After a production break of two years, a new 911 Turbo was again offered in 1991, based
on a new 911 platform dubbed “964”. It retained the 3.3-litre engine, which had been upra -
ted to 320 hp. In 1993, Porsche modified this model, enlarging displacement to 3.6 liters
and increasing power to 360 hp. In 1995 the next generation, “993”, was released and set
new standards in sports car manufacturing. The 3.6 liter engine made 408 hp with the help
of twin turbochargers, accelerate from zero to 100 km/h (0-62 mph) in 4.3 seconds, and
on to a top speed of 293 km/h (182 mph). For the first time, it made use of an all-wheel
drive system adapted from the 911 Carrera 4.

Fun thread!
Call it what you want but there is no doubt this 1975 to 1989 911 variant is the single most important race inspired production car Porsche has ever produced.
Oh, and yes by the way, everyone of them had 930 serial numbers, all 15 years of them!

Here is the serial of my 1984. Clearly a 930 because of its gray market Euro status but I do not see a 930...A 93 but not a 930 serial inside. Care to explain? All ears here.

I am looking over some of my serial numbers of my 911 Turbos. I do not see a 930 in them.

The 911 equivalent would be;
WPOZZZ91ZDS100567
It does not jump out at you like the '70's serial numbers but they were all 930's and not 911's just like the 912's, which had their own serial numbers, were not 911's.
Neither the 964 nor the 993 have a separate turbo number, they are all 964's or 993's as do the later 911 derivatives to the best of my knowledge.

Thanks for that explanation on a real 930. That I never knew that you had to find a 93 and a 0.
To answer once again the OP's question as to what he has - a 1989 930 or 911 Turbo here is that link and a quote of page 27 with the time cutoff for 930 cars.
http://books.google.com/books?id=rOK...page&q&f=false
Quoting from page 27-->
"1986 was year for great rejoicing among Porsche enthusiasts as the 911 Turbo (930) was reintroduced to the United States, Porsche wanted to call it the 911 Turbo and drop its 930 designation"…two more paragraphs on specs follow calling it a 911 Turbo.
930 was officially dropped from the name.

I own what I have been calling a 1989 930, bought from Sloan. A friend who has had numerous Porsches/turbos insists that it is a 911 turbo, not a 930. I believe type 930 was the internal designation. Is it correct to call my car a 930 or is there a distinction? He also says no 930's were made in 1989.
Thanks for any information.
Thanks for any information.
Thanks for starting an entertaining thread
To specifically answer your question;
Richard sold you a 930 so I am sure your serial number confirms it is a 930
Your 1989 can be called many things but in the end it is a 930.

All Paper work says 911 Turbo on Automan9's car. I know it . I have seen it. I have worked on his car.
The VIN notwithstanding.
That VIN just confirms continued use of the sequence of '93xxx0' after '930' was no longer used as the car's name.

I have an 87 930. I just got my Certificate of Authenticity back from Porsche. It says the model is "911 Turbo Coupe". Engine number/type is listed as M930/68. Transmission number/type is G930/36. Based on this info, I would say either designation is correct. But who really cares! Just drive the hell out of it and enjoy!

For mine it is listed as, "1979 930 Turbo Coupe" .
It would be interesting to find what others have.
