Update 16: Awaiting final paperwork

Date: 12/05/12

The current waiting game and absolute silence in this section of our GTspirit Garage has happened because of a problem with the Ultima GTR. The paperwork has still not been finalized, because the problems with the engine. The engine is not legal in many of the European countries, which means that the owner has to swap the engine for a different one and file the documentation again. All the time the car stayed in doors and has not moved a bit. Hopefully we will see the car soon on the roads in Europe.




Update 15: Awaiting final paperwork

Date: 23/10/11

The owner has indicated that the Ultima GTR has completely been finished. The vehicle is ready to the hit the roads. The only point that still needs to be sorted is the paperwork. The owner is waiting for the final documentation and license plate. Stay tuned for more in the near future and the first driving footage.

Update 12: Problems with the drive train

Date: 03/06/11

Problems have occured with the drive train. There is a problem while sending the revs/min to the ECU. The motor had to be taken out again. After a week the motor was placed back in the car again, but now there is a problem with the starter. The dents do not fit 100 percent together. So another few days of waiting. Problems over problems. but they are still in a good mood.




Update 11: Body is on the chassis

Date: 24/03/11

The system has shift lights, built-in warning lights, rpm, speed, gear, and warning alarms. You can change all the settings of the system via USB and a PC. A great addition to the setup of this sports car providing all the appropriate data to the driver.

Update 4: Basic construction has started

Date: 04/03/11

The first phases of the basic construction have started. The construction has started with the basic monocoque. All future parts are connected to the structure shown on the pictures. The owner has tested the seats. They are like a second skin and weight almost nothing. For the feet you don’t have a lot of space. Especially in height there is not a lot of space in the cabin. A Digidash will be outfitted behind the steering wheel.

The installation of the fueling system has also been accomplished. In the end it was quite more complicate than expected, because the car has two fuel tanks: one on the right (installed yet and one on the left side (not installed yet). Brakes and main part of the cooling system were installed as well.
