Shamu, I'm not going to be running a built motor yet. Something happens, it happens. Ill be ready. But these cars can handle a lot FI on lower boost settings. It's the heat ill have to see about.

VQ can handle low amounts of boost in street and ax situations. I haven't seen a single boosted VQ engine last on track. You're probably looking very limited motor life without forged internals and major cooling efforts. Why not prepare yourself now rather than face inevitable later in the season? There's a reason I'm not running blown motor anymore. Wasn't willing to spend money on rebuild yet. Oh well you will have some short term fun! I guess you could just replace motor with used one from junk yard. To build proper FI track motor you're looking at $20 k easy. That's why I'm saving my pennies for GTR motor that will run stock or even less boost. I will be interested in how long a stock motor lasts on track with turbo though its a cool experiment. Bets? I say 6 track days.
You need RFS and fuel regulator with most any boosted application. Marketing from companies selling turbos and non RFS fueling systems will tell you otherwise but don't believe them. Stock non return system isn't designed for any level of tuning in my opinion. You will always be compromised without return and a proper regulator.
