Low boost single turbo is a good option, depending on what the situation is like in SA you. I know here everyone 2nd shop would setup a single turbo for you for not too expensive. Turbo parts and accessories are cheap too thanks too all the jap guys.
Std motor yields pretty awesome results from a low boost single turbo. Best bang for your buck when it comes to these cars.
Also, 80km in 4th? Thats light 2nd gear territory
