There is a wide range of options and formulas to apply when planning to build your next rally car, but have you considered the freedoms and flexibility offered by the Club Rally Car regulations?
Club Rally Cars are now eligible to score points in the Gary’s Motorsport Tyres NSW Rally Championship and the Techworkz Development Rally Series and is open to all 2WD vehicles.
In a nutshell, the rules require the constructor to use an engine from the same manufacturer as the body and in the same format. That means that a Nissan Bluebird can use a SR20 16 valve twin cam engine, rather than an L20 or Z18. The same applies to a Datsun 1600 or Datsun 1200 coupe. It also means that a Holden Gemini (and there are plenty of them out there after the successful Gemini Rally Series), can use a 4ZE1 Rodeo engine or, better still, a C20XE 16 valve twin cam Cosworth engine (sold here in the Holden Calibra’s). Retaining the original engine format means that if the original engine had 4 cylinders, so must the replacement.
Turbo chargers are free if the original car had a turbo. In the case of the Bluebird, it was sold with a Z18 turbo, so a SR20 turbo can be used.
Suspension modifications are to be in accordance with either PRC and/or Classic Rally Car regulations, which allows the fitment of a 5 link or 6 link (watts linkage) rear suspension to the Bluebird, Escort, Datsun 1200 coupe or Gemini.
Generally, everything else is free, but it is a good idea to read over the very brief regulations before you take out the angle grinder. Of course, you may also wish to read over Schedule R which is the basis for all rally cars (roll cages, fire extinguishers, etc).
These regulations allow the competitor / constructor to enjoy the freedom of design and the thrill of driving a powerful 2WD car sideways again. There is a growing number of Club Rally Cars that are competing – and quite a few more under construction. Many are being converted from the much tamer PRC regulations by replacing engines and suspensions set ups.
Come and join the fun. Build your car to these simple regulations.
