The Stock Aluminum LS2 in my experience tops out at about 650rwhp before blowing
So you can easily be at the same power you were at before,
If you want to go the Turbo route again there's three major turbo Kits for the GOATS

APS http://www.airpowersystems.com.au/ls1/us_gto.htm
Gen TT from Australia http://www.ls1turbo.com.au/
Later Iron Block 408 Maybe? and you'll be well over 600RWHP in the GOAT
weight issue is covered with power Given, I pull on my Brother(04STi) and Causin(94)Supra all day and I'm a Big guy 6'3" 305lbs. and my car is stock
Tire issue Varies what you do some people have gotten away with running 305s in the rear, but mostly 275s
Shifter is an easy fix with a GMM Ripshifter
