This is my 1976 911S Targa, I have owned this car for almost 30 years. I have tried hard to keep the car original, up to date and healthy. It is a driver car, not a show car:
.
At speed, and especially into the wind the nose of the car always felt uncomfortably light. If you look at the above picture you can see I added a front spoiler made of 1/2 inch plexiglass. The spoiler attaches to the front tow cleats and can be easily removed to return the car to it's original configuration. I ordered two black plexiglass pieces from the Internet, one was 40x4 inches and the other was 40x5 inches at the cost of around $70 because I wasn't sure about down force and clearance issues. I installed the 40x4 inch spoiler and the front of the car has been locked to the road ever since. There has been no clearance issues since I installed this spoiler years ago but I don't attempt to drive through deep ditches or huge speed bumps. Here is a picture of the 40x5 inch spoiler I did not use:
I wanted to install new adjustable Koni Sport struts/shocks but the "gland" nut would not come off. I bought/ordered every tool recommended but nothing worked. I ended up modifying a 41mm socket and after lengthy hammering with a 1/2 inch air ratchet I finally got the original nuts off. Here is a picture of the modified socket:
I rebuilt the CIS fuel distributor and after many tries I finally figured out how much sealant is needed. Here is a picture of the precise amount of anaerobic sealant necessary to reseal the distributor. Too little sealant? You will smell gas. (You will rarely actually see a leak.) To much sealant? The fuel distributor does not work right. And by the way, the fuel pressure O-ring and spring are key to making the rebuilt CIS fuel distributor work correctly. Here is half of the distributor with sealant applied: (Notice there is less sealant around the pin-hole spot, smaller hole in the middle right.)
This is my effort to try and give back to the Pelicanparts community. Over the years I have found Pelicanparts Forums helpful to get me looking in the right direction. I would warn newcomers though at times the suggestions are misleading and sometimes 100% wrong so do your homework and try and understand how things work
