Brian Luti known as Scooter on the Two-Sixties forum, runs the Dreadnought Garage in Callander, Scotland and apart from running a ZT race car was the 'go to' person for anything supercharged.
Some of the must-do inspections and modifications to keep your Two Sixty/R75 on the road and your mind at ease, taken from Scooter's and the collective's experiences shared on the Two-Sixties website
Fit the orange clip to the fuel filter**
Fit the Two-Sixties replacement heater hose and restrictor (if missing), only fitted to ZT and ZT-T
Modify the block on the bonnet opening mechanism**
Fit Two-Sixties Black Olive replacement heater valve
Check your spark plugs, they are known to work loose, or worse, to blow out of the head. Take them out once a year regardless of mileage, lube the threads with a LITTLE copper grease and replace. DO NOT OVER TIGHTEN as there are only a few threads in the head. Torque to 12Nm (8lb/ft.) no more.
Fit a lighter throttle return spring to improve accelerator feel and minimise cable sticking
Be heard! Fit the second horn, originally removed by the factory as a cost-saving measure
Service your air conditioning compressor and especially replace the original refrigerant/oil mixture with the CORRECT quantity
Fit the Two-Sixties magnetic hex-head sump plug
Adjust the handbrake carefully, you may have to replace the handbrake compensator and the handbrake shoes**
Check rear sub-frame cross-tube for rust
Check welding on the four radius arms on the rear sub-frame
Fit Scooter's rear wheel alignment replacement bolts and bushes kit (and new radius arms if needed), available from Austin Garages (Nick Bonthrone)
On pre-facelift cars, check the rear springs for broken top coils
Throwaway the four locking wheel nuts**
Upgrade the cooling fan resistor or the complete cooling fan unit**
Keep an eye on the alloy wheels as they are known to crack at the rim and cause slow leaks - they can be welded to make good**
**Common to all ZT's and R75 V8's
