2017 NUGGET NATIONALS
Sporting and Technical Regulations
Version 1.3 – Published on 01/04/2017

Introduction

Nugget Nationals is intended to be a friendly, cheap and informal competition in which competitors participate at various sprint events with the goal of achieving the fastest lap time in an inexpensive vehicle.

Nugget Nationals is a reaction to the exorbitant spending and modifying that occurs in sprint competition.  We at Nugget Nationals believe that supersprint motorsport can be fun and challenging at an economical price point, and that those with a smaller budget should be encouraged to participate.  With this in mind we have inaugurated this series, to promote friendly competition and participation for anyone interested in club level motorsport.  The series focuses on competition between drivers, with cars and modifications taking a back seat.

Technical Regulations

T1.  Preamble

(a) The intention of the technical regulations is generally to limit costs, maintain a degree of parity and encourage regular participation with reliable vehicles.  Competitors must keep all records of expenses on a vehicle, as budget may be a consideration for future events.

(b) In addition to these regulations each vehicle must also comply with the entry requirements of each individual event.  These requirements are the responsibility of each event organiser and may vary.

(c) In any situation where a vehicle does not comply with these Technical Regulations due to a modification, existing or otherwise, a competitor may apply to the Organisers for an exemption and that vehicle or modification may be accepted if in the opinion of the organisers it does not constitute a competitive advantage.

(d) Where the term OEM is used this shall be defined as: A component produced by or identical in specification to a component produced by the original manufacturer of the entered vehicle intended for fitment to a vehicle complying with T2 parts (a) and (b).

T2. Eligible Models

(a) Only vehicle models produced in full volume and eligible for road registration in Australia may be entered, this includes vehicles eligible to be fitted with an Australian Compliance Plate, a Low Volume Used or New Import Identification Plate or equivalent only.  This does not include vehicles imported and registered through other alternative schemes.

(b)  For the purposes of part (a) of this regulation, ‘full volume’ refers to a vehicle that was supplied to market complete and in a state ready for registration in numbers exceeding 10 per annum.  This excludes kit cars, clubmans, and replicas.

(c) Vehicles not complying with part (a) of this regulation may be accepted at the discretion of the Organisers.  A competitor wishing to enter a non-complying model must apply in writing to the Organisers.

(d) Only models fitted from the factory with an engine with capacity less than 1,500mL swept volume are permitted.  The engine must comply with regulation T5.

T3. Purchase Price

(a) The initial purchase price of the entered vehicle may not exceed $3,000.00 excluding any  fees or registration costs.

Note that $5,000 is considered to be the absolute upper limit that a vehicle should cost complete and including all modifications, excluding any safety devices, a vehicle exceeding this is not in the spirit of Nugget Nationals.

(b)  Notwithstanding clause (a), in cases where the competing vehicle was purchased before 01/01/2014 for a price exceeding $3,000.00 the ‘purchase price’ of the vehicle may be taken as the present value as documented on Redbook.  In this case the value will be taken as the lower limit of the private price range.  Alternatively a different value may be accepted at the discretion of the Organisers.

(c) The vehicle must be purchased at a price within or valued within the price cap specified in part (a) in a running or near running condition.  A vehicle purchased requiring major repairs or not in running condition will not be accepted within the value limit unless that vehicle is demonstrated as being generally available within the price limit.

T4. Modifications

(a) The following Technical Regulations specify all allowable modifications. If the regulations do not explicitly allow a modification that modification is not permitted. Where a modification is permitted that modification may not perform any other supplementary purpose beyond the permitted function.

(b)  In general a modification is defined as: any removal, modification, substitution or addition of components.

(c) Any factory option for a vehicle model variant is not considered a modification and may be freely added or removed except where it directly contravenes a Technical Regulation.  Only options available for the exact model, year and variant are permitted to be fitted or removed under this rule eg. “Nissan Micra LX 3 door hatch” is a model variant and only options available for that unique variant, such as A/C or power steering may be added or removed.  Road Vehicle Descriptors as published by RVCS will be used to determine available options.

(d) Entrants must provide complete details of their vehicle and modifications to the Organisers prior to each round.

(e) Wear and maintenance items may be replaced with components sourced from non-OEM manufacturers, but must be of identical specification, geometry and mass as the OEM item originally fitted to the vehicle.  Components complying with this clause are not considered to be modifications.

(f)  The Organisers will be the final judge of what constitutes a modification.  If any doubt exists as to whether any alteration to a vehicle is considered a modification, or if a modification is compliant with these regulations the Organisers should be contacted in writing for clarification.

T5. Engines

(a) As per regulation T2 the engine capacity must not exceed 1,500mL swept volume.

(b) Notwithstanding point (a), allowance is provided for capacities in excess of 1,500 mL in cases where engines, originally displacing less than 1,500 mL, have been rebuilt.  However the OEM stroke and cylinder liners must remain and a maximum bore oversize of .060” or 1.5mm is allowed.

(c) Any form of forced induction including nitrous oxide, whether originally fitted or aftermarket, is not permitted.

(d) Only one engine is permitted per vehicle.

(e) Rotary engines are not permitted.

(f) Engines must be of internal combustion type, supplementary electric motors are not permitted.

(g) Engine swaps are permitted only to replicate a manufacturer’s option or model/trim variant for the vehicle in question, and the vehicle replicated must comply with sections T2 and T3.  However any other options or trim differences which were included in the different model or trim variant must be replicated fully, such as more luxurious, heavier interior features and A/C.   All engine conversions must be approved in writing by the Organisers.

T6. Engine Modifications

(a) Engines may be rebuilt or reconditioned to the manufacturer’s original specification however all components fitted must be OEM as specified for the particular engine and vehicle model, alternative components to those factory fitted to that particular engine variant in that model are not permitted whether OEM or not.  Resizing of crankshaft journals and cylinder bores during the rebuilding of an engine is not considered a modification.

(b) The cylinder head and block may be resurfaced but the combined total of material thickness removed from both items may be no more than 0.020”.

(c) The following engine modifications are permitted:

(d) Engine oil sumps may be modified or replaced to assist oil control.

(e) The exhaust system may be freely modified downstream of the mounting plane of the exhaust manifold to the cylinder head.
