    Default Engine Codes

    Good morning all
    Can anyone enlighten me if there is a book available that lists the Renault engine codes, or alternately can you identify an 842/05 fitted to R12.
    I have a number of blocks from different vehicles, and currently trying to work out the best for our hillclimb car. As always I appreciate any info you can give
    Cheers
    Harvey

    An 842-05 is a (originally 1251cc, 71.9mm bore) Renault 12GL motor, with 9.5:1 compression, running a twin-choke 32DIR Weber. It was only used on the Australian assembled 12GL sedans between 6/1974 and 12/1974. Note that many of the 842-xx motors are now likely fitted with a “normal” rest-of-world 73mm bore piston liner kit.

    There is no single book featuring all the permutations (which include all the technical details of all models). However all the Renault 12 (iron block) permutations are featured in the Renault 12 workshop manual of the era, as well as some of the "quick reference" guides. Note that there are other variations such as the alloy block 12 Gordini, US spec alloy block cars, which have their own workshop manuals, and technical notes for the 1.4 litre cars in addition to the normal workshop manual. Renault don’t like making things easy when it comes to documentation.

    842-01 is 1251cc 8.5:1 compression
    810-02 is 1289cc 8.5:1 compression
    810-05 is 1289cc 9.5:1 compression (manual trans)
    847-05 is 1397cc 9.5:1 compression (manual trans)
    xxx-06 indicates the motor was originally used with an automatic transmission.

    Default Engine Codes

    Thanks Simon, I had quite a bit of info in manuals and my own notes, but a fire in the house destroyed that and a bit more.
    I had started to compile a list of engine codes and relevant specs, guess it's a case of starting over again.

    That's not too good losing all the info in a fire. I've got another problem, since I've gone cold turkey from 12s, I've forgotten more than I can remember.....

    I always felt the 1251 was more of a revvy engine than the 1289

    Not so much the 1289 which is the same apart for the piston diameter but did (does) rev better then the 1.4.
    But the 1.4 had larger bearings and a heavier flywheel so were smoother.
