Any non-factory boosted car is going to have alot of maintnance. Supercharger or turbo. I wouldn't make a decision based on that. If you spend the money on a nice wastegate, overboost is going to be rare.i pick a supercharger over a turbo because less maintnace. just put in the the supercharger you will never worry about over boosting.
Just wanted to add, yes, you absolutely can buy all of that shit at Andy's, but Andy's is overpriced. The days of Andy's are waning...much better deals to be found elsewhere now...its funny u say that i found mad upgrades at andy`s auto sport... they sell the chips, superchargers, turbo kits, you can even boost the f`n thing if u waned to. i kno if u swap with a 3.5 and do a 4 in intake low 13s alone on street tires
