Thanks for this thread! I found it very informative. I too was curious about putting a blower on my ‘03 I have all the mods done but I think I’m just going to switch to 3.73 gears for now (I do a lot of highway driving) I don’t want a blower to end the life of this 152k mike engine, even though it is in excellent running condition with a lot of new parts and tuned!!!
I LOVE my 3.73 gears! Just make sure you change out the gear on the output shaft or your speedo is going to be WAY off! Mine was registering roughly 20mph more than what I was running. It actually saved me from a ticket once or twice! Look down and it reads 90 but you're only doing 70. Lol.
