Few questions before I pull the trigger

- I have been told that supercharging these motors causes main bearing failure early on and it's a high chance of happening...just wondering the legitimacy of this

-Im doing BE bearings and rod bolts at the same time, this is the best known combo now to insure a longer engine life as far as I know...is there anything better out there ?

- I was quoted $4100 to install the supercharger and do rod bearings/bolts is this fair or expensive?

-how many of you have been supercharged for more than 30k miles with no issues ?
