Hey guys, i was just wondering if anyone has any experiance with turbocharging an Astron II EFI. I have a few quesions.

1) What turbo was used, and did you need a new exhauset manifold
2) How did you get a vacum reading for a BOV (Did you drill into the plenum chamber)
3) What PSI is it safe to run to and did you use an intercooler (did detonation occur at higher boost without one)
4) What was the first thing to break
