Federation Internationale De L'Automobile Regulations for the "Junior" Racing formula

Article 1: Definition

Cars of the "Junior" formula are one-seater racing cars, whereof the fundamental elements are derived from a touring car recognised as such by the F.I.A. (minimum production 1,000 units in 12 consecutive months)

Article 2: General characteristics

  1. minimum wheelbase : 200cm
  2. minimum track : 110cm
  3. maximum width of body : 95cm (measured outside)
  4. maximum engine cylinder capacity : 1,100cc
  5. minimum weight : 400kgs

The latter weight limit, however, is reduced to 360kgs for cars with a cylinder-capacity of 1,000cc or less. the above mentioned weight shall be measured with the car "in running order", viz. without ballast, and with all accessories required by these regulations but with dry fuel tank(s). The ballast which is prohibited is that of a removable type. It is, therefore, permissible to complete the weight of the car through one or several ballasts incorporated to the materials of the car, provided that solid and unitary blocks are used, and that they are fixed by means of a tool and offer the opportunity of being sealed on, should the officers entrusted with scrutineering deem it necessary.

Article 3: Mechanical elements

  1. the cylinder block, including the cylinder head and cylinders (if the latter are removable) must be those of the engine belonging to a car classed by the F.I.A. in the Touring category.
  2. the gear-box must be that of an F.I.A. recognised touring car. Complete freedom is left with regard to the number and staging of gear ratios
  3. the system and principle of feeding (by carburettor or by injection) must be the same as on the car from which is taken the engine
  4. the cylinder capacities specified in the present regulations may be achieved by modifying the original bore (increase or reduction). No modification of the stroke is permitted.
  5. the car must have an automatic starter.
  6. the braking system shall be such that the pedal normally controls four wheels, and in the event of failure of any one part the pedal shall still control at least two wheels of one same axle. For cars constructed before 1962:  the braking system and principle (viz. drum-brakes or disc-brakes) must remain the same as on the car from which is taken the engine

Article 4: Body

The body, open and offering only one seat, shall comprise, around the pilot's seat, an anti-roll bar, protecting him from being crushed should the car turn over. There shall also be a protective device against fire as required by the International Sporting Code (Art. 125)

Article 5: Silencer

The supplementary Regulations of the events may provide that an efficient silencer is compulsory.

Article 6: Prohibitions

It is not permitted:

  1. to use an engine with one or more overhead camshafts
  2. to use a self-locking differential
  3. to change the number of crankshaft bearings
  4. to change the location of the camshaft

Article 7: Fuel

Only commercial fuel, as defined by the F.I.A. shall be used

FIA International Racing Formula 3

as described in 1964 CAMS manual

The original FIA rules governing this formula are identical with the Formula Junior rules, as illustrated above, except for the following variations

  1. The maximum cylinder capacity of 1000cc may be achieved by modifying bore and or stroke dimensions
  2. The gearbox is limited to 4 forward gears, and must have a reverse gear
  3. The engine is limited to 1 carburettor with a 3mm thick, 36mm restrictor mounted between its flange and the intake manifold
