Have you ever wanted to own an electric car? or have you ever wanted to drive a Porsche 911? I wanted both, so I decided to build one. This blog is here to document my journey as I convert a 2002 Porsche 911/996 Carrera 2 from a gas guzzler to a completely electric vehicle - not a hybrid!

After months of learning and small tests around the neighborhood, I've reached the conclusion the transmission needs to be replaced.  The main issue is a mechanical grinding noise whenever the RPMs get above 900RPMs.  Once I reached the conclusion the transmission had to go, I put the car back up on car jacks, removed the back wheels, and the bumper to prepare for the major change.   

I looked into replacing the automatic transmission with a manual transmission.   I priced out the manual transmission and all the supporting equipment (clutch lines, clutch pedal, shift cables, shifter, console, longer transaxles, etc.) and the total ranged about 4-5 times the price of a used automatic.  Once I figured out how expensive it was to convert, I turned back towards just replacing with another automatic.  

Today I ordered the new transmission.  While the car is up on jacks, I'll also install the Orion BMS system and try to get the 6 remaining batteries mounted.  More to come when the new stuff arrives.


  1. Too bad about the transmission. Aside from the cost, delay, and extra work to install, it will be nice knowing that you have a strong, new unit matched to the motor.

  2. What were the prices you encountered for the used auto and manual transmissions?
