Recent News & Work

911 Design added 9 new photos.

Our customer recently brought us his 1986 Gemballa Avalanche Turbo. There were only 12 of these cars made total. These cars sold new for between $250,000 and $300,000 depending on the options. We have been tasked with getting this car running as well as some restoration work.

We have removed the motor and transmission from the car to do a full inspection. We've completely dismantled both the motor and transmission.

After dismantling the motor we know exactly what we need in order to get it running again. The motor requires all new oil lines, a spark plug wire set, a new restrictor fitting, turbo feed line, and oil return tube.

There will be more photos to come of this work in progress!
