Rebuild Overview

The purpose of this Tech article is not to provide a step-by-step guide to rebuilding a 911 motor. There are complete volumes of Factory manuals on this subject as well as a multitude of books and other written material that cover the specifics of engine rebuilding. This article is simply a collection of my own personal experiences and tips meant to aid in understanding various aspects of a rebuild. It is my hope that this article will become one of many tools used by the determined DIY'er as...

By Motor magazine 1964

otor, the leading British car magazine then, performed a very first test on the original 911 in 1964. Instead of reproducing the whole long article, I quote the most important parts in below The subdued and pleasing noise from the back tells you where the engine is and so does the freedom from wheel spin and the ability to use a lot of the power on corners. But rear-engined handling characteristics have virtually disappeared - there are many front engined cars which are more sensitive to...

Porsche 911 Sc History

Porsche 964 Restoration

When 928 and 924 had been launched, Porsche's director Dr. Fuhrmann planned to reduce the production scale of 911. As a result, all 911s were replaced by a single model, 911SC, whose 3-litre engine was detuned to 180 hp probably intended to prevent it from having a higher top speed than the 928 which was supposed to be the successor of 911 . Although raised to 188 hp in '80 and 204 hp in '81, it was still relatively unremarkable. That was the darkest period in 911's 34 years history. Fuhrmann...

Valve Adjustment

Doing a valve adjustment on a 964 is an easy, straightforward task - but time consuming. If you want to save a few bucks on your annual maintenance costs and get to know your car better, you should definitely start here. First, the question of how often Some people say every 15,000 miles, some say 30,000. Some people say twice a year, some once a year, some say every oil change. Follow your owners manual for the Porsche recommended service interval - but I try to do mine twice a year. One way...

Early Handling Problems and Solutions

The rear-bias was always a problem to 911's handling. Any tail-heavy cars have a tendency to oversteer. If such oversteer is not adequately suppressed, lost of control may occur. Although there were some racing car being more tail-heavy and more powerful yet had fabulous handling, say, the 1000 hp 917 Can-Am race car which carried near 70 weight at the rear, the production 911 lacked their racing-spec aerodynamic aid as well as racing tyres - the original 911 rode on 165 tyres with 4.5 in rims...

Almost Perfect

No one would have expected the already radical 964 would receive even more radical changes after serving for just 4 years, especially if one used to the rhythm of the car's development. Now, we know Porsche's decision was right - the 993 was not only a refined and modernised sports car, it also delivered a lot more driving fun than its predecessor, bringing the company a revival in sales after the slump in late 80s and early 90s. The mission of 964 was finally fulfilled by the 993. The success...

White Gauge Faces

Most of the time when you do an upgrade to your car it is on the exterior, engine, or under the car, so when your driving you don't really get to appreciate it as much as others who can see it from the outside or hear it . Here is a project that you will be able to enjoy every time you get in your car. Replacing the gauge faces with ones of another color is a personal choice as there are some that feel this is changing the originality of the car, but it is YOUR car so do what makes YOU feel...

Wheel Drive

The 4WD system used by the 964 Carrera 4 of 1989 was one of the most advanced designs for the time being. It was derived from the 911 Carrera 4x4 racer which won Paris-Dakar rally in 1984, but the experienced learned from the 959 supercar also helped. In fact, Porsche described it as a simplified version of 959's PSK system. The system employed 3 differentials plus a multi-plate clutch. The epicyclic gear centre differential normally sent 31 to the front axle and 69 to the rear. Although it...

As with all 911's, the Porsche 964 is easily modified to provide additional handling and performance. It should be noted that, as with any automobile manufacturer, Porsche attempts to build automobiles that will be accepted by a majority of people as well as meet strict governmental and...

What Does Din 51607-n Unleaded 95 Ron 85

GeneralAs with any automobile, body modifications are available for the 964 from mild to wild. Whilst some owners would not touch a thing on their car's, others feel the need to customise every aspect of their car. Various suppliers provide a range of body modifications for the 964, though perhaps the wildest designs have to-date come from Strosek. Strosek has produced a range of body conversions that include the incredible shark eye wide body conversion, down to a simple front and rear bumper...

It was determined that the general shape of the new 964 would retain the essential character of the 911, obtaining near zero lift in the front and rear without the aid of the whale tail or other additions that would break the classic lines of the 911 the whale tail, whilst performing its function extremely well, was largely criticised in it's time for its excessively obvious lines . This was essentially obtained via the use of a fully covered floor pan, and an electrically operated rear wing...

The longlive 901 engine

Th e Type 901 flat-six engine was as legendary as the car itself. Think about it, although a lot of progress had been made during those years, the basic structure was never altered. For 34 years it remained to be air-cooled and, most important, the basic dimensions governed by the distance between bore centres remained unchanged. It sounds rather unbelievable, especially knowing the differences between the earliest and the latest engines - 2 litres versus 3.8 litres 130 hp versus 450 hp - I...

One day you will start the car and think that have a cat caught in your fan because of the noise. Don't despair, this is an easier and cheaper fix than you might think at first. Porsche has discontinued the original blower motor for the 964's and they have replaced it with the 993 version 993-624-328-01 . This is the exact same fan and for the 115 you pay Pelican Parts...
