What is the 914 SIG?

The 914 SIG (Special Interest Group) is a part of the Porsche Club of America (PCA). It was founded in 1998 to foster pride in ownership and to increase communication among 914 owners. We do this via this web site and by hosting events, where 914 owners can drive, socialize, and compete.

How do I join the 914 SIG?

Membership in the 914 SIG is free and does not require PCA membership. You can join the 914 SIG by visiting our Registration Page. Registrations are reviewed manually.  Once you are approved, you are encouraged to add each of your cars to your Garage.

Can you compare the various 914/4s for me?

Here is a quick run-down of the 914-4 models. Some sources say that a few 1969 models were produced.

Can you compare the various 914/6s for me?

All 914/6 models were delivered with engines from the 1969 911T. This engine had Weber 40 IDT carbs, a 8.6:1 compression ratio, and was rated at 110HP @ 5800 RPM.

Here is a quick run-down of the 914/6 models:

Some sources say that a few 1973 models were produced.

In addition to the production models, there were 914/6GT race cars produced...27 in 1970 and 20 in 1971. 916 models were produced in 1972...a total of 11. However, these were not really race cars.

What should I watch out for when buying a 914?

Rust. There's no such thing as a rust-free 914. If you've found a totally rust-free 914, check again. Chances are you'll find rust somewhere. Particularly prone are the battery tray (check for it having been replaced) on the right hand side of the engine compartment, everything below that (which includes the right-rear suspension!), the firewall in front of the engine, the jack points on the sides of the car, longitudinal members of the frame (the inner rockers), the rear of the rear trunk floor, and the lower channel where the windshield sits are known trouble spots.

Body Flex
. You can check for flex with the "Big Butt Test." Get someone of large size (>200 lbs) to sit in the passenger's seat (the side with the battery!). With the door closed, roll the window up. Then try to open the door. If the window sticks at the top or back edge, the body is flexing. Also try the driver's seat. Body flex is fairly bad news. It can be cured, but it is generally time-consuming and expensive.

Oil Leaks
These are relatively common. Some of the cures are cheap in parts, but expensive in labor (e.g., oil cooler seals). The oil pressure idiot light sender, on top near the distributor, can leak. Push rod tube seals commonly leak, but can be replaced with the engine in the car! The aforementioned oil cooler seals, the galley plugs, and the front or rear main seals are also not uncommon leaks. The engine may need to be removed to fix these.

Bad Shifting
The 914 is known for transmission shifting woes. Sloppy shifting is part of the car's character, especially on the pre-73 cars. Replacing the shift linkage bushings can help; these parts are plastic and can wear quickly. Most cars will crunch going into first gear; this is generally regarded as "normal", except for a brand-new transmission. Some will also crunch going into second. This may mean a rebuild is in the near future.

Broken Clutch Cable Tube
Another source of "transmission" grinding noises is the clutch cable. Specifically, the tube in the center tunnel that the cable goes through. Rust and time can cause this tube to break loose from the tunnel wall, which will keep the clutch from fully disengaging. This causes grinding when shifting gears.The tube can be re-welded, but it may require cutting open the tunnel.

Top Leaks
Take the car to a hand spray wash and see if water gets into car. If so, check for signs of previous water damage.

Taillight Leaks
The taillights can also leak water into the rear trunk. Look under carpet for rust.

Broken Hinges
The hinge pivots for the rear trunk lid can break off.

DPO Mods
Lots of 914s have had significant modifications performed by the Dreaded Previous Owner. These modifications can be good, but more often, they totally screw the car up! Have someone knowledgeable check the car for condition and originality. Know what you are buying.

What is a Ramble?

A "Ramble" is an event for 914s and their owners. The name was invented by John Dunkle in 1997. The term "Ramble" has been used to describe 914 events all over the US. These events normally involve several activities (Car Show, Technical Seminar, Rally, Tech Quiz, Autocross, Tour, Banquet, etc).

What is a Register?

First of all, there's no charge for Register or SIG membership and we are quite non-commercial. You should also understand that at least where the 914 SIG is concerned, there is one SIG and 6 Registers. Further, your car is the member in a Register, but you join the SIG. The 914 Special Interest Group and its 6 Registers is a sub-division of the Porsche Club of America (PCA). It is intended to comply with the general objectives of PCA, i.e.

"To encourage the highest standard of safety and courtesy on the highways, and to increase the enjoyment of owning a Porsche by the exchange of technical information and by engaging in such automotive and social events as may be agreeable to the members"

Additionally, the 914 Special Interest Group & Registers go one step further and provides a focal point for owners of 914 Porsches, to be able to discuss and learn more about this particular model. The primary focus of each Register is to build a database of each car model with the various identifying numbers, options, and modifications. We also organize events, where owners can meet, socialize, compete, and learn more about their cars.

Is membership in the 914 SIG private?

Yes.  All personal information is hidden from public view.  Some information may be available to your fellow members.  Sensitive personal information is never published (name, address, phone number, e-mail, VIN, etc...).

What's in it for me?

There are many benefits to being part of the 914 SIG. These include being a part of a friendly network of owners with whom you can discuss the pros and cons of just about any issue pertaining to your car. Whatever the problem you have with your car, some other SIG member has probably had a similar experience and could give you advice. We organize events where you can meet other 914 owners, see and touch their cars, talk about issues, plus learn more about how to maintain, upgrade, and use them. We have fun!
