Thanks for pointing those things out, all are an easy fix which ill do. But i think the gas tank is the correct shape (take a look at the image i attatched). ALso, by collector do you mean the box in the engine which holds the filter (I really dont know the propper name
)? IF so, ill just remove it as im gonna model a turbo so it wont need one, maybe a cold air intake for the turbo instead. Finally, it might go into GTA IV (if it will be possible) or that realistic racing game which i forgot the name of
