Bigger fuel lines
Question for the pros. When you turbo a beta engine do you have to upgrade the fuel lines or do the stock ones handle as much power as you can throw at it? I ask because you upgrade every other part of the fuel system like injectors and pumps but I never hear of anyone doing anything with fuel lines themselves. I would think the lines would be the weakest link in a high horsepower scenario.

You would only need new fuel lines if your fuel pressure was dropping below your desired values (and you had already upgraded your fuel pump).
You're more or less stuck with the stock fuel rail, and the hard metal connector that attaches to it..so even if you upgraded fuel hose diameter, you're point of most restriction is that stock metal line that's 1/4 inner diameter.
