Same as your alky car has. Just have to make sure everythings happy with alky
- Alky carb or injection
- Different fuel pump maybe, or just change the seals in your current if it can't take alky. Maybe a bigger pump however if your current one is marginal on gas
- Lines/fittings/seals, all have to be good with alky
- Regulator (alky happy)
- Fuel filter(s) (alky happy)
Fuel cell should probably be ok, but might want to check (yours has a sender in it IIRC).
The nitrous system is another whole deal though. For simplicity since you'd have to change out pricey items and also re-tune it I'd just use gas in the nitrous system and alky for the motor for now
then maybe switch once you've sorted out the main fuel delivery system.
