TURBOCHARGING / SUPERCHARGING
Due to the complexity of the ADRs after 1 July 1976 affected by the fitting of a turbocharger or supercharger to
a naturally aspirated engine Transport SA requires the vehicle to be fitted with a Second Manufacturers ADR
plate to demonstrate compliance with all ADRs.
Passenger cars manufactured prior to 1 January 1972 and passenger car derivatives (car type utilities and
panel vans) manufactured prior to 1 July 1976, fitted with petrol engines, can be fitted with a turbocharger or
supercharger without Transport SA approval.
Passenger cars manufactured on or after 1 January 1972 but prior to 1 January 1974, fitted with petrol engines,
can be fitted with a turbocharger or supercharger without Transport SA approval subject to the following
condition:
• The carbon monoxide exhaust emission output emitted by the engine does not exceed 4.5% when tested
at the manufacturers recommended engine idle speed.
Turbo timers are not to be fitted to vehicles manufactured on or after 1 January 1972 (ADR 25 Anti-
Theft Locks). ADR 25 requires that the normal function of the engine only occurs when the ignition
lock is in the engine on position.

MY car is registered as 'modified' with Vigil. When my car is on the road with the charger (this week, when I get an HIF44...) I will notify them. I asked prior anmd they said 'as long as it's road legal'. In SA any car prior to Jan 1st of 1971 can have a supercharger or turbo without approval or notification of Transport SA.

But still must comply with emissions? This is one of the reasons Minis can't really legally be fitted with a Weber, because it is a non-standard carburettor and TSA therefore require very expensive emissions testing to be carried out. (From what i remember anyway)

Yes willy you are correct, kinda. It says on the Modification in SA thing from Transport SA you can do it to a pre 1971 car as it doesn't ahve to comply with emmission controls. <edit> it actaully says pre-72... Heres the actaul quote.... If you don't have this writing, go to mods of A/A+ section, go to a sticky about State laws on mods and follow the SA links and downlaod it, it's called 'info_bulletin_3.pdf' or something Quote: Passenger cars manufactured prior to 1 January 1972 and passenger car derivatives (car type utilities and panel vans) manufactured prior to 1 July 1976, fitted with petrol engines, can be fitted with a turbocharger or supercharger without Transport SA approval.
