Plan #1 power
1. Trick Flow heads $999.00
2. Trick Flow Street Intake(idle-5500) $400.00
3. Trick Flow cam $150?
4. BBK Longtube headers chrome(it's cheaper than jet-hot) $240
5. Matching shortie H-pipe $120
6. Your choice aftermarket mufflers $91 for the pair
Well that is your $2000. All those parts will give you, your REAL power. The little stuff is alot easier to buy as you go along. Those things should get you a real solid start, and you'll be running mid to low 12's with a few more parts...Injectors.....etc. Those parts will give you a solid base for your new engine, and will keep you satisfied until the supercharger. Another thing you should consider is buying used parts, saves alot of money.
Plan #2 chassis & tune-up
1. BBK subframe connectors $90
2. BBK strut tower brace $110
3. Battery relocation kit $210
4. New cap and rotor $17.99
5. Spark plugs $15
6. Plug wires $40
7. New shocks(varries big time on what kind you go with)
8. Ahhh I could keep going on forever, but I'd go with plan #1.
