Q8. I want to buy a 911. For what should I look?
Q9. What should the VIN or engine number look like for my car?
Q10. Does anyone have a checklist for potential 911 buyers?
=========================================
Q1. What's a 911?
A. Yikes. Okay, in 1963 Porsche announced the 901, a car based on
the venerable 356 model. The car was renamed 911 because
Peugeot had a copyright on all 3-digit car model numbers with a zero
in the middle. The 911 has gone on to become, arguably, the most
popular car ever produced by Porsche.
The 911 engine is an air cooled (or oil cooled) six cylinder opposed
design. The cylinders bolt onto the crankcase such that displacement
increases are often achieved by replacing the pistons and cylendars.
The body of the car was designed by Ferdinand "Butzi" Porsche (Ferry's
son) while the engine was designed by Ferdinand Piech (Dr. Porsche's
nephew).
=========================================
Q2. Which 911 Should I Get?
A. The standard answer is "get the newest 911 you can afford".
Unfortunately, it's more complicated than that. I had occasion
to meet Joe Rusz, Senior Editor at Road & Track (gratuitous name
dropping, here); his answer to this question was simply "if you
can afford it, get one with Motronic Fuel Injection" (those'd be
the ones built in 84 and after).
You really have to decide for yourself what you want. Many feel
that one exception to the 'newest you can afford' rule is the
middle year cars (1973 through 1977) due to their short engine
life span (circa 50K miles). Others (like myself) prefer the
early mechanically injected cars (light and sparcely appointed
with quick, torquey engines) over the newer 911SC (with their air
conditioning, electric windows, and bullet-proof engine).
Hopefully, the information in this document will help you decide.
=========================================
Q3. What are the classic problems/areas to check on 911s?
A. The 911 is a really good car but there are a few problem areas
that have, at various times, plagued this particular vehicle. Here
is a list of some of the most notorious problems.
A1. RUST -- Rust can destroy a 911's unit-body and this can be really
expensive (impossible?) to fix. Watch closely for rust, particularly
with the pre-galvanized bodies (pre-1976?). Check the seams around
and edges of the doors, trunk, and hood. Check the jack points and
the torsion bar tubes.
A2. CHAIN TENSIONERS -- The timing chain is held taught by chain tensioners.
The early (pre-1984) timing chain tensioners tended to wear out and
suddenly collapse causing your pistons to come in violent contact with
your valves. This gets expensive. The 1984 and later cars used oil-
fed tensioners which solved the problem.
Many early 911 owners have had their older chain tensioners replaced
with Carrera tensioners. This modification costs around $300-$400
plus labor. Adding carrera tensioners is extremely expensive on
pre-1967 engines.
Some have modified their tensioners by adding mechanical tensioner
guards. These devices keep the tensioners from collapsing
completely when they collapse.
A3. EXPLODING CLUTCH -- The 911SC (1978-1983) used a rubber-centered
clutch which would eventually fail and send rubber pieces sailing
throughout that part of the transmission. These clutches should be
replaced by a spring-centered one.
A4. EXPLODING AIRBOX -- The 2.7 and 3.0 liter 911 cars use a $200 airbox
that can, if the car backfires while starting, explode. For around
$15, you can get a pop-off valve that is supposed to fix this
problem.
=========================================
Q4. So, what's all these problems I keep hearing about the 2.7 liter
911s?
A. It's a tragic story. Porsche increased the displacement of the
2.4 without providing enough cooling and, to add insult to injury,
the US models had thermal reactors (except for 1974) that got
REALLY hot. The result is, among other things, head studs that
pulled out of the crank case (due to thermal expansion of the
cylinders) and destroyed valve trains. All of this resulted in an
average engine life of about 50,000 miles (your mileage may vary --
HA! I was *waiting* to use that line).
So the natural follow-on question (so natural, in fact, that I'm not
breaking it out into its own question) is "can anything be done to
mitigate the design flaws of the 2.7?" The answer is:
- Have the case helicoiled or timeserted. These threaded
inserts are installed in the crank case to hold the
cylinder studs tightly and keep them from pulling.
- Use Dilivar or Raceware studs. These studs won't pull
out because they expand with temperature at the same
rate as the cylendars.
- Replace the 5-blade fan with an 11-blade fan.
- Add an extra oil cooler.
=========================================
Q5. What are the differences between the various 911s?
A. There's *lots* of differences:
First, there are numerous of body styles:
Coupe 4 seats (well, 2 and a couple postage
stamps) and a hard roof. You know. . .
a COUPE
Targa Like a coupe, but with a roll bar and a
removable top. The earlier targas had
soft rear windows, but the later ones
had glass.
Cabriolet A full-on convertible.
Speedster A version of convertible, but with a
short windshield and a fiberglass tonneau
(the 356 speedster was different, but we're
talking about 911s here).
There are several trim and tune options:
T, E, S The early years (the latest any of these
were produced was 1977) cars in touring,
injected and super (also fuel injected)
states of tune.
Carrera For the earlier cars, this was the quickest
standard customer car. After 1983, the Carrera
was the standard customer car.
SC This was the standard car (there was also the
turbo for some of theses years) between 1978
and 1983.
H, N Rare models: Homologation (20 made in 1973) and
a Euro model in 1976.
L The one-year replacement for the 911S in the US.
R, RS, RSR 911 in race trim. These cars are always rare
and expensive.
Turbo This one is, well, turbo charged.
And, finally, there are the various changes over the different model
years. Major Eras Include (the names are, partly, my own):
- 1964-1968 short wheel base (SWB, 2211 mm to be exact). In
contrast, the long wheel base (LWB) is 2268 mm long.
- 1968-1973 early power. These 2.0, 2.2, and 2.4 liter 911s
(my personal favorites) saw either mechanical fuel injection
or carburetors (actually, in 73.5, the 911 T was
electronically fuel injected).
- 1974-1977 middle-year 911s. These cars had the 2.7 liter
engines that had a notoriously short life span. This is
the beginning of the crash bumpers (with the accordion
sections at the edges) and K-Jetronic fuel injection.
- 1978-1983 911SC. These 3.0 liter SCs are powerful,
luxurious, and nearly bullet-proof.
- 1984-1989 Motronic Carreras. Like the 911SC, but with a
3.2 liter engine and Motronic fuel injection.
- 1989-1994 964 (original 911 Carrera 2/4). These cars have
the one-piece, all body color bumpers and the engine cover
that raises at 50 MPH to form a wing.
- 1994-today 993 (today's 911)
Note: Years given are model year. The model years start in August
or September of the previous year (example 1972 model year starts
in September of 1971). Much of the research for this document has
been clouded by research materials not specifying whether they
discussed calendar year or model year.
More specific differences are given in table 1, below.
=========================================
Q6. Okay, so how do I tell the difference between them?
A. Well, you asked for it. . .
-- Short Wheel Base 1964-1968 -------------------------------
1968 and earlier cars have a shorter wheelbase than the 911s built
in 1969 and after (recognition hint: the torsion bar tubes are right
next to the SWB cars' rear wheel well -- there's a gap in the LWB
cars). Other accoutrements of the SWB cars are:
- glass lens covered headlights,
- exterior door handles that opened via an exposed push-button
(rather than the flying-buttress protection or trigger of
later years),
- no side marker reflectors,
- Hella 128 fog lights mounted through the bottom half of the
front bumper,
- a vertical structural strip running under the rear engine
grille,
- sunroof models during these years had a drain slot above the
rain gutter above the back side windows,
And, in the interior:
- chrome instrument bezels with green lettering,
- ceiling-mounted rear-view mirror (1968 was as well, but
it was break-away type)
- a one piece under-dash knee guard,
- pleated door pockets, and
- push-buttons to open the doors from the inside.
Until 1971, non-S models had silver painted slotted steel wheels;
S models had Fuchs alloy wheels.
911s before the 1967 model year had the '911' designation
diagonally across the lower right corner of the engine cover and
the PORSCHE script in one piece (well, actually it was two pieces,
but it looked like one) on the bottom.
--
1964 2.0 liter
There were four 901 prototypes produced (serial numbers 13326, 13327,
13328, and 13330). Porsche went on to build 125 first year (1964) 901
cars.
RECOGNITION TIPS:
The 1964 cars have no rocker-panel trim and and no model designation on
the engine lid or on the dash. Supporting clues are that 1966 and earlier
911s have wooden dash trim and open A-frame window cranks.
OPTIONS:
--
1965 2.0 liter
RECOGNITION TIPS:
These cars look nearly identical to the 1966 cars. The things that
separate these cars from the 1966s is in the interior. The 1965 cars have
no wrap-around knee guard, aluminum backing on the wood dash trim, or
rubber shift boot (I think they were leather).
Both years are similar in that they have the rocker panel trim (this is
not found on the 1964 cars), wooden dash trim, and open A-frame window
cranks.
OPTIONS:
A four speed transmission became standard mid-model year.
Sunroof, tinted windshield, enamel porsche crest on wheels, chrome
plated steel wheels, gasoline heater (LHD models only), ambient
temperature gauge, driver's side vanity mirror on sun visor, recaro
or ferrari seats (actually, both are made by recaro), leather seats
headrests
--
1966 2.0 liter
Weber carbs replace Solex mid-model year. S model introduced mid-
model year. Fuchs wheels introduced. Targa (with soft rear window)
introduced. 911 introduced in US.
RECOGNITION TIPS:
These cars look nearly identical to the 1965 cars. The things that
separate these cars from the 1966s is in the interior (see the 1965
description). Of course, if the car is an 'S' model, it has to be
a 1966 or later.
US models have all chrome vertical bumper guards (standard equipment) --
911S bumper guards are all rubber.
OPTIONS:
sunroof, tinted windshield, enamel porsche crest on wheels, chrome
plated steel wheels, gasoline heater (standard on S-models) (LHD models
only), ambient temperature gauge, driver's side vanity mirror on sun
visor, recaro or ferrari seats (actually, both are made by recaro)
leather seats, headrests
--
1967 2.0 liter
Only 4 prototypes and 19 'production' 911Rs were made.
RECOGNITION TIPS:
The window cranks on 1967 cars are of the covered A-frame type but had
a hard plastic knob.
US Models have chrome vertical bumper guards with a rubber strip
(standard) -- 911S bumper guards are all rubber. The bases for the
switches on the dash go from black to chrome and the dash is matte black
(S model had basket weave vinyl).
OPTIONS:
Rear window wiper optional from this model year on (on Targas, too?),
tinted windshield, rear-window defroster (vertical wires), sunroof,
sportomatic (introduced in 1967), enamel porsche crest on steel wheels,
chrome plated steel wheels, Fuchs alloys on non-S models, 100 liter fuel
tank, gasoline heater (standard on S-models) (LHD models only), ambient
temperature gauge, leather covered steering wheel (standard on S-models),
driver's side vanity mirror on sun visor, leather seats, headrests, recaro
sport seats (available in leather, vinyl, vinyl with with corduroy, or
vinyl with hound's tooth inserts).
-- Early Power 1968-1973 -----------------------------------
Side marker reflectors appear in 1968 (tacked-on side reflector) --
in 1969 and later, the reflectors are incorporated into the turn
indicators. 1968 and later 911s have the model designation mounted
horizontally centered on the engine cover (the hood?). The covered
headlight is replaced with a rim bezel over a sealed beam headlight
(US) or a lens covering bulbs (non-US). Inside, the window cranks
are one-piece with a soft vinyl knob. The door pockets under the
arm rests are vinyl-covered hard cardboard.
1969 is the first year of long wheelbase 911s; these came with
flared fender arches; also, the targas come with glass rear windows.
The 911s between 1969 and 1973 used a 2 battery system.
From 1970 on, the doors opened via trigger-type door handles. The
under-dash knee guard is a two-piece (with room for the ash tray in
between) unit during this time period.
1969 and later, the rear-view mirror is mounted to the windshield.
--
1968 (A Model) 2.0 Liter
A very few targas had glass rear windows at the end of the model year.
RECOGNITION TIPS:
Matte black wiper arms. US Models have chrome vertical bumper guards with
a rubber strip (standard) -- 911S bumper guards are all rubber. S Models

Q7. But, Porsches are known for performance; how do the models differ in
performance?
A. Check this out.
** Note: 0-60 times are subject to the talents (and the desire not
to damage the car) of the driver. For this reason, the times
will vary from source to source. This table has used several
different sources (some of which do not match). Don't take the
0-60 times too seriously.

=========================================
Q8. I want to buy a 911. How should I go about it?
A. There's lots of stuff.
DECIDE WHY YOU WANT THE CAR. Decide whether you want an old
show car, a race car, a daily driver, or whatever. This should
help you settle on which types of 911 are best for you.
HOMEWORK. Get some books and research the different cars (check
out the references at the end of this FAQ). When it comes to
information, some is good, more is better, and too much is just
enough. Figure out which years, models, and features of 911 are
in your list.
Once you decide on a car type, find out what can go wrong with
them and how much it can cost to fix them.
PRICES. Check out the usual sources for prices and availability:
- The "Porsche Market Letter", (619) 727-4856, 1 yr
subscription $55
- Panorama (the newsletter to the Porsche Club of America),
- The "Auto Trader", (800) 845-9612. Some regions also
have the "Sports Car Trader".
- "Hemmings Motor News", (800) CAR-HERE
- The "Recycler",
- The local newspaper,
- The "Penny Saver",
- Porsche Swap Meets.
Shop for insurance at this point. You don't want to find your
dream car and find out you can't afford to insure it. Insurance
companies vary drastically (as do the costs for the different
years and models).
Check out financing. If you want an older 911, you may have some
trouble getting a loan. Used car loans usually only apply to cars
with a value listed in the Kelly Blue Book (those that deal with
older cars usually do so based on a rediculously low estimate of the
value of the car). If you don't have extra dollars hanging around,
you may have to get an unsecured loan (at a higher interest rate).
FIND A MECHANIC. Especially if you are able to look for a car
close-to-home, find a mechanic before you start looking. Ask
friends who their mechanics are and talk to PCA and POC personnel.
Talk to your mechanic (and other knowledgeable people) about what
you should be looking for in a car.
LOOK FOR A CAR. Now that you know the car (and price range) for
which you are looking, start your search. Take lots of information
including VIN, etc.
CHECK-OUT THE CAR. If the car is long distance, you may have the
owner take it to a mechanic first. I tend to like to use Porsche
dealers for long distance check-outs. Dealers may be more
expensive but they should know their stuff.
If the car is nearby, check-out the car in person first. Look for
features, rust, and general condition. Test drive your car: does
it start easily, does it accelerate with no flat spots, does it go
into all gears easily?
TAKE THE CAR TO A MECHANIC. Have the mechanic do a compression
check and a leakdown. Have him make sure the engine numbers match
the VIN. He should be able to itemize everything you need to put
the car into street concourse condition (even if you don't want
to show the car, this will give you an idea of everything the car
needs). The list should help you decide whether you want this
car and, if so, the price range for the car.
CHECKLIST. Check out the following checklist for some ideas of
stuff for which to look.
BUY THE CAR. Join the PCA / POC. Enjoy your car.
=========================================
Q9 What should the VIN or engine number look like for my car?
A. Well, I'm not going to go into that here 'cause it's long and
there are so many other books that do it completely. For VINs,
check out Bruce Anderson's "Porsche 911 Performance Handbook" or
"Guide to Purchase & DIY Restoration of the Porsche 911". For
both VINs and engine numbers, consult Brett Johnson's Restorer's
guides or "The Used 911 Story" (for US cars only).
=========================================
Q10. Does anyone have a checklist for potential 911 buyers?
A. Here it is. . .

Have the owner send receipts and pictures.
If you can, have the owner send a videotape. The tape should
cover the following:
- Walk around the car, SLOWLY
- Get closes-up (check for rust & mating) of:
headlights, door seams (door closed), hood, trunk,
fuel filler,
- Get under-car shots including:
suspension pickups (front and rear), jack receiver area, and
tortion bar tubes (under car).
- Interior shots (take-off targa top, if applicable). Get:
front seat, rear seat, dash, instruments, console (if
applicable) carpeting
- Engine compartment
- Trunk area (lift carpet around batteries).
Have owner take the car to a mechanic.
Maybe have owner take the car to a body shop (check for rust).
Check seams for evenness and for rust (portal closed)
