Before you start modding your car I recommend that you freshen it up first with a few basic maintenance.

The stage upgrade that I'm about to mentioned is not a rule of thumb that you have to follow, many fellow Dsmer's went about it in a different way, this is just an idea what route to take.

I will go on details in another section in WHY, and How, to do some of the mods.

Stage 1: Nice tuneup, suspension(anytime)

Stage 2: K&N open Air Filter, or HKS Super Mega Flow(mine)

Stage 3: 3" Cat-Back Exaust, Fuel Pump

Stage 4: Dave Brode UIC Pipe, Blow of Valve

Stage 5: Boost gauge, boost controller

Stage 6: EGT Gauge, Air/Fuel Gauge

Stage 7: 2.5" Downpipe, 3" catalytic converter

Stage 8: Turbo

Stage 9: New Clutch

Stage 10: Fuel Injectors, Air Fuel Controller

Stage 11: Front Mount Intercooler

Stage 12:Engine work, Porting, etc, etc, I'm not going there
