The owner of this Opel Vectra C 1.9CDTI already did some performance enhancing upgrades to his car. There were still some upgrades left on his wishlist and he wanted us to carry out some of his wishes. We already tuned allot of GM diesel engines.

The swirl flaps were deleted because these flaps can break off and end up in the engine where it can cause damage or engine failure. We also replaced the water pump in combination with a distribution service using a new timing belt, pulleys and tensioners. The butterfly valve was also deleted from the throttlebody. We also removed the DPF and deleted it from the software. We also closed the EGR in the software.

The rear trailing arms received new bushings and inserts. We also placed KCPerformance Whiteline bushings in the rear axle and in the new front trailing arms. We also placed butterfly trailing arms from a Saab 9-3 in the rear of the Vectra.

The engine received a service with new oil, oil filter, fuel filter, interior filter and brake fluid. The software was updated to a KCPerformance stage 2 chiptune with 420NM and 200hp. These upgrades ensured that the already tuned Vectra now has more power and grips more in the corners.

The Vectra also received new suspension parts developed by KCPerformance and AST. This is the cream of the crop of suspension technology. The set is adjustable in height and damping, it is calculated especially for the Vectra C Estate. We also installed AST topmounts and a Wiechers racingline strutbrace to make the complete package fine-tunable. This way your can set it to a hard setup for track use or a comfortable setting when you are cruising along the highway pumping The Gap Band out of the speakers.

We also replaced all the major components of the airconditioning and to top it off we installed a new Forge intercooler with new silicone hoses. This way we gained another couple of horse out of the engine. The brakes were replaced bu better EBC brake disks and Ferodo DS2500 brakepads. The driveshafts were also thanked for their service and replaced by a new pair. During this process we also replaced the transmission fluid. The Vectra is now ready to be loved and used by his sympathetic owner.

After driving some kilometers the client came to us with the question if we could get more power out of his engine. KCPerformance is known for always going the extra mile compared to other tuners, on all fronts. We advised him to do an upgrade to a KCPerformance stage 4. We flashed te ECU with a KCPerformance stage 4 chiptune and replaced the turbo and downpipe with a enlarged turbo (GT1749MV) and downpipe without precat. We also replaced some silicone hoses together with the thermostat, tensioner-, crankshaft- and idler pulley. The car also received an oil service with new oil- and air filter. After checking the car on a large list of points we decided to top off the power steering oil.

The beautiful Vectra is now back in top condition and received a nice power increase. Again, it was real pleasure working on a Vectra that is in pristine state and has allot of power.
