Following to add

1:
In 1985 the Volvo Turbo Cup Volvo got a intercooler and more horse powers, about 250 hp. Also available was the same 16  
     inch wheels/tires and rear spoiler on the trunk as the group-A Volvo.

2: Many of those parts that are equipped on a Volvo 240, can be bought over the counter at you local Volvo dealership store.
    The Turbocharger kit (Volvo Turbo Cup) was available to buy at your local Volvo dealer to (it was and expensive kit, but hey
    you needet it to compete in the Turbo Cup Series), also stronger sway bars that makes miracle on the suspension on a Volvo
    240. To be able to keep the car on the road or track is always funny even if you do have or don't have 250 bhp on the wheels.
