WTB parts for trenchy

so im on the hunt for more hp and im not sure even where to start on the 1127 motor , so im after parts that people might have that they might want to sell and also after some advice as what to do as I know there is plenty of suzi nutters out there and I know fark all about them , what works , what doesn't

the plan is avgas , igniton advance self done or buy the kit or go full house dyna with multi graphs and 2 stage , jets pod filters dyno tune and sidewinder exhaust , im after torque mostly

yes / no advice , fill me with your info :D

Turbo will give you all the torque you could wish for

NOS is the torque monster , simple cheap no need for ign advance (works better with slightly less in big doses) and you can adjust it in 10 min or even fit electronicly adjustable units.
