Cause like in GT4 you would have to chose: N/A or Turbo, so I don't know if you could mix the two in real life  
2nd, what is it all about those compression rates like 11,1:1 ? Can someone explain a bit more about this, like why they calculate this etc...
Thank You  |
This is the reason i am setting up those new info sections. Good questions like this always lead to informative answers.
Nth's post is pretty much it in a nutshell.

this is an article one of our members, who has become a lurker, wrote awhile back on turbocharging. It's pretty long and contains alot of really good information that i think will answer your question.
Most engines can go from NA to FI with no work being done to the internal
components providing you don't run any more than 6-7psi. However you can't take the turbo/supercharger off an engine that was setup for it right out of the factory.
Same as setting up an engine to handle high boost pressures. You can't revert back to NA without changing the internal components back to a natural aspiration set up. IF you were to do this, it would be cheaper just to have a NA engine laying around in anticipation.
