Well the LSD should make whatever you do...fun. if you dont have to smog test it...
Do an intake and 4 brl swap, up the exhaust to dual 2 1/4 pipes, install and "MSD" ignition, recurve the distributor with some lighter springs and you can keep the egr if you want.. because its just a milage enhancer and shuts off when you stomp on it. It only opens at cruise...Oh and put air in your tires, that helps too-B.Obummer.
After market air cleaner is a good idea too.
Flex or electric fan will free up 5-20hp depending on the rpm.
I don't gotta smog test thankfully
