1973 sees Chrysler going all-out to win. In Group 1 Saloon Car Racing. All major UK rallies. TV Rally Cross. Which is good news for all the motor sport enthusiasts who've been clamouring for special performance kits and parts for their Imps and Avengers.
So here they are - all you need, developed, tested and proved by Chrysler Competition Centre. We want you to get the best out of them, and we're ready and eager to give you free advice. So if you have a problem, just write, phone or call in to the Special Tuning Section.
We're also getting ready to meet your demand for purpose-built performance variants for racing and rallying. So now you can compete on equal terms in club and national events. Or simply improve your car to really outstanding road performance.
For three years in succession, the privately entered Imp prepared by George Bevan and driven by Bill McGovern has won the British Saloon Car Championship.
And in its first year's racing an Avenger GT (the Mopar Avenger) prepared by Chrysler Competitions Manager Des O'Dell and driven by Bernard Unett, has won its class and come second overall in the Britax Saloon Cal' Championship.
A similar car, driven by Colin Malkin, won Class 1 of the RAC Rally. And two privately-entered Avenger GTs took second and fourth place.
Join us on the starting line.

Complete 998cc engine, built to Imp Sport specification but with 998cc block and pistons. The power output of this unit is 65 bhp at 6000 rpm.
The engine comes complete with clutch, distributor, plugs, manifolds and carburettor.
If you prefer to build your own 998cc engine, we can supply a cylinder block, pistons and head gasket. To suit individual competition requirements a range of special parts is also available - such as modified cylinder heads, camshafts for road use, for rallying or for circuit racing, lightened flywheels, con rods and competition clutch.
Competition inlet/exhaust manifold for twin DCOE Weber carburettors, equally suitable for racing and rallying (CTS 1023A).
Available also for rallying in a skidded form (CTS 1023B) mated up with transverse silencer kit (CTS 1024) which gives a legal noise level.
The air cleaner (CTS 1022) is essential for any dust or dirt driving, including road use.
Springs of varying heights and rates suitable for everything from fast road motoring to all types of competition, are available.
CTS 1206 and 1207 are heavier duty versions of the standard fitting; CTS 1208 and 1209 are shock absorbers with competition settings for road use and club events; and CTS 1211 is for serious international competition use in the roughest conditions.
This kit consists of a pair of modified king pin carriers which, when fitted to a high pivot car, give ½° negative and, with low pivots, 2° negative.
Disc brake conversions, developed for racing and road rallies such as Motoring News Championship events. Alloy calipers are included, which are not suitable for general road use and should only be used on pure competition cars.
VG95 brake linings which, allied to brake drums in a good condition, give adequate braking for all except tbe most rigorous conditions.
Foot brace bar as fitted to thc passenger side of 'Works' cars, giving bracing for the navigator and a foot rest for the driver.
This is as used on 'Works' cars for rough road rallies and is capable of withstanding a tremendous amount of punishment. It covers both transaxle, sump and radiator.
This is just a skid which guards the sump and oil filter and is designed for smooth rallies and events such as Auto-cross.
Ready to accept all normal Imp fittings.
Of Imp Sport pattern, ready to accept all normal Imp fittings.
As homologated in Group 2. These require considerabie bodywork modification to allow wider wheels to be fitted and are only the external spats to cover the wider wheels. Competition Centre can advise on how to modify the bodywork.
Rallye dashboard (CTS 1502) which accepts the normal switches etc. off pre-1969 cars. It also accepts the following instruments: 140 mph speedometer (CTS 1503); 200 kph speedometer (CTS 1504); 8000 rpm tachometer (CTS 1505); 2" fuel gauge (CTS 1506); 2" temperature gauge (CTS 1507); temperature gauge transmitter (CTS 1508).
Alternator, ammeter, control box, all the brackets and wiring etc. to fit an Imp.
7" Lucas Light Units of either Continental (driving) long range or fog type (CTS 1113). Lamp bar to mount four 7" lights, (CTS 1114).
These stop the fanbelt flying off at over 7,500 rpm and alter the ratio of speeds of the water pump and either dynamo or alternator.
These are intended purely for road work. We do not recommend modifying Mk. 1 engines.
This is the normal Imp Sport set-up and is complete with air cleaner, and longer throttle cable.
When fitting this kit to the standard Imp engine, remember that inlet valve stem oil seals should be removed.
This is complete with all clips end brackets and represents a worthwhile improvement on standard.
Complete with all parts necessary for the conversion, and supplied with a competition type cooler unit.
This is a Sport head with 10.4 : 1 compression ratio, opened up and polished exhaust port and reshaped inlet port, giving a very worthwhile power increase to both sport and standard engines (further modifications are required for use with a standard engine).
This is only a selection of the many kits and parts available for Imp and Avenger conversions. If you would like any more information, or simply to discuss possible future conversions even if you do not have anything currently in mind, we should be glad to talk things over with you.
