There are plenty of vendors that manufacture carbon fiber stock hoods for the galant. The catch is the wait time and cost of shipping.
That said, I see you would like your galant to weigh-in at less than 3,000 lbs. -Thats a huge weight drop for this platform and will entail quite a bit beyond obviously the hood and trunk.
If you haven’t already I would encourage you to consider removing/replacing the following:
1) 4WS system
2) Cruise Control
3) Emission System
4) ABS System *Full removal to include associated wiring, Ring Gear, Sensors, etc.
5) Relocate battery and replace with a lightweight unit
6) ACT/Fidanza Light weight Flywheel
7) Driveshaft Shop Aluminum Driveshaft
8) Balance Shaft Delete
9) A/C System *Full removal to include associated wiring behind the dash
10) Manual Seatbelt conversion from LS/GS 89 - 93 galant
11) Replace front seats
12) Replace fuel tank with a Fuel Cell
13) *Hop on the treadmill and shed 10 lbs of driver weight
