Hi I have a 2001 GD290 Turbo Diesel Automatic GWAGON. It's a beautiful car, a beast ,runs well and has been maintained well. But it's slow! It's a pity, coz it's an amazing car. My question is simple: HOW CAN I MAKE IT FASTER? My knowledge on cars is limited and I live in Nairobi, Kenya. Can a simply change the engine? Put in a more modern, more powerful Gwagon Engine? Put in another kind of engine? I just want to make it faster!
