If you keep the boost low run good gas & conservative timing.
You should not need & J&S or intercooler right away.
Problem is, once you start making boost it gets addicting & you'll want to run more & more boost, & you will not have the good & safer supporting mods to your turbo set-up.
You'll just need to have self control, it's hard, though, ask Snowman.
Curious, what turbo do you have, what are the specs?
