Ok so I have started the work on the GU. Its a little difficult as I need to keep it mobile so its gonna take sometime. I was hoping to get the airbox lid modification and turbo installed today but I need the car this arv and have just finished the air box mod. So here are the pics of before and after with the airbox lid. You can see how restrictive the factory setup is.
