Rob1000 your correct in what your saying but to change everything that you need to, to make the car run actually sufficently well again its much more complicated then that.
My mate has pulled his turbo out of his 180 thinking a simple fix, he's recently having to spend $5000 to fix all the bits he's now ****ed up.

Just keep the turbo in, DISPLAY your p plates as you won't lose another 3 points
