Adapt the Porsche parts, adapt the VW parts, or full custom. Now that the trans is located where itвЂ™s new home is going to be, it is time for shift linkage! There are three options for shift linkage. Step 4: Modifying the Frame Tunnel and Adapting the Shift Linkage With the mount position determined, and the trans in a static position, build a front mount.Д«ottom view of fabricated front trans mount I welded ears to the outside of each frame horn for the Volvo trans mount studs to bolt to.

These mounts will also make it simple to swap in solid aluminum mounts for the strip just like the Gene Berg intermediate mount. I selected the hardest rubber versions for maximum rigidity. These are quite generic and I found at least four different brands. I determined that a mount built from scratch would look and fit best. In this conversion, I elected to build my own mount system because the 911 mount needed over four inches added to its width to fit the way I wanted. It is possible to adapt the original 911 front mount. It is helpful to have the floor pan upside down at this point for obvious reasons. With the rear mounts bolted down and a floor jack supporting the front of the trans, you can begin to figure out the front mounting system you canвЂ™t buy this stuff, you have to make it! Keep using the straight edge on the bell housing and measure to the torsion tube to keep the bell housing parallel and square. Step 3: Fabricating the Front Mounting System Do not remove any more material than necessary!Д¬learancing for clutch bowden tube bracketД¬learancing for right-front of trans case Also lightly clearance the front of the trans and also the torsion tube. In order to get the rear of the 901 as close to 22.75вЂі back from the torsion tube.

A hole must be cut into the bottom of the pan. The input for the shifter on the 901 exits the bottom of the trans rather than the middle like a beetle. It is good to clearance as little as possible to keep some strength in the frame horns. Mark the areas to be clearanced using a paint pen or marker. ItвЂ™s far easier to modify the car to accept the new 901 location then modifying the body for an engine that sits 1вЂі further back! Clearance the frame horns for the sides of the gearbox and for the clutch tube bracket off the side of the box. It is important to have the 5 speed as far forward as possible because it is about 1 inch longer than the beetle trans. With the beetle trans this measurement was 22.75 inches. When you first lift up the 901 and try to fit it using the rear mounts as reference to where it needs to be, you will begin to realize how much larger and longer the 901 really is! Place a straight edge parallel to the ground and on top of the input shaft as a reference, then measure to the torsion tube one foot from the center on each side. Now the transaxle can be coupled to the floorpan. The nice thing about performing the rear mount adaptation first is that it gives you a static point to work off of for fitment to the VW pan. Use a bit that is just larger than 8mm so that the mounts fit nice and tight. We recommend a spare set of Urethane rear pad mounts because they do not have studs (they use nuts and bolts) so you can place the mount right over the area and mark it perfectly. Step 1: Adapt the Rear Transmission MountsДЄdapting the rear tranny mounts to the 901 is done by drilling holes in the 901 to match the holes in the original beetle transaxle. It is an appropriate gearbox to use for the 5 Speed Conversion outlined below.ДЄ late model 914 Side Shift transmission can be used for a 5 speed conversion but requires additional work and components not covered in the article below.В The Porsche 915 gearbox is larger and not the subject of this do it yourself conversion article. The 902 is the same size and has the same internals as the 901, but different gear ratios. The 902 Porsche Gearbox is found in the early Porsche model 912. 1969 still used a push type clutch, but 1970/71 switched to a pull type clutch system. Late 901 Porsche Gear boxes (1969-71) were made of magnesium. They were made of aluminum and had a push type clutch. Porsche 901 gear boxes were used inВ the Porsche model 911 from around 1965 to 1968. Identification marks are located on the bottom of Porsche Gearboxes. Tips for Identifying an appropriate 5 speed Porsche Gear Box Candidate And of course, you will need to locate a good used Porsche 901/911 or 902 5 speed gear box. Type 1 VW Transmission Conversion to Porsche 5 SpeedДЄn IRS rear suspension setup is required rather than a swing axle setup, because the Porsche box is only available in an IRS configuration, and can not be converted to swing axle.
