Slide 1- 5-Speed Conversion: Installing a Porsche Gearbox into your Type I IRS Chassis

Slide 3- Starting Point:
In order to install a 5 speed gearbox you must first begin by locating one.
For this conversion the following gearboxes are acceptable starting points
901 and 902 (5 Speed)
901/911 and 914 gearbox
915
For this guide we will discuss the 901/902/914 family of gearboxes. The 915 will follow the basic procedure

Slide 4- Distinguishing Porsche Gearboxes

This is an example of an early 911 gearbox. (used in the 911 from around 1965to 1968)
These boxes are referred to as 901 boxes.
Identification marks are located on the bottom of the gearbox
The 902 boxes are identical to the 901. It was found in early 912, and has the same internals as the 901 but different ratios

914 Side Shift Transmission
Late 914 utilized the side-shift configuration.
Look at the similarities in the case to the tail shift.
Nose cone and shift rod and fork internals differ
The 914 Side Shift transmission can still be utilized for the conversion but will require additional work and components
