Presentation of the Renault 5 Turbo training document
The Renault 5 Turbo technical training document (ref. 7701446962) is the official material published by Renault in September 1980 to introduce the new R5 Turbo model to the network's technicians and mechanics. It presents in detail the technical innovations of the Renault 5 Turbo MR221 : the 1,397 cm³ C7K Turbo engine developing 160 hp DIN, the Garrett T3 turbocharger with its 0.36 A/R and the Bosch K-Jetronic mechanical injection — an unprecedented combination on a production vehicle of this displacement in 1980.
This training booklet covers all the technical specificities of the R5 Turbo compared with standard R5 models: fuel supply circuit, uprated cooling, 5-speed type 369 gearbox, adapted braking and specific suspension. It is an essential complement to the MR221 manual for understanding the model's operating principles and working on the R5 Turbo mechanical parts properly.
