In 1968 the FIA decided to re-classify the 911 T into the same category as the 911 S. Considering the T road car weighed 52kg less than the S and that for competition it could be equipped with a more powerful engine, the S Rally was dropped in favour of the new T/R. Built from 1968 for customers who wanted to go racing and rallying, the T/R was the first homologation special based on the 911. Unlike the highly experimental R, the T/R would be eligible for GT class competition (specifically Group 3) and quickly found favour with professional and amateur drivers alke.
   
Almost any combination of parts could be ordered, from a 906 engine to a steel body, whatever the customer required they got. All cars were received without sound deadening (saving 25kg for starters), the suspension being suitably lowered and anti-surge fuel tanks with dual pumps installed. Two engines were available, the less expensive option having been a 160bhp unit from the standard 911 S. This could be enhanced with the optional Rally Kit that featured larger carburettor venturis, open inlet trumpets and a twin outlet exhaust, all of which took output to 180bhp. At the other end of the scale, you could opt for the 230bhp 906 engine with its titanium conrods, Carrera 6 pistons, lightened flywheel and stonger clutch. When the 906 engine was specified, a limited slip differential was was normally fitted as standard. Additionally, it was commonplace for customers to order R parts for their S engines, valves, ported heads, pistons, Marelli ignition and pressure side oil filters all cropping up.
 
Externally, materials could be mixed and matched as the customer desired, some cars being completed with lightweight glassfibre panels whilst others were manufactured with standard steel shells and stock glass windows. Cockpits were generally stripped of all unnecessary fixtures and fittings. A variety of options were available including closer ratios, long-range 100-litre fuel tanks, a dry sump oil system with a cooler under each front wing, extra driving lights and a limited slip diff. About 35 T/R's were made, four of which were right-hand drive, most cars differing in detail.
