    Default GS Rotary

    Guys, I thought some of you might be interested to see what a 12A looks like under the bonnet.... Blasphemous, I know- but what can you do.

    Hey,

    Ive got a few quick questions to ask about ther GS conversion?

    1. How does the driveline hold up with all the more power, does it have to be modified in anyway?

    2. Will a 12a turbo or a 13b fit in there or will there be drivetrain issues with all that power?

    3. Is it a tricky conversion, does much have to be modified under the hood to get it all to work?

    Thanks heaps!

    1. it has the same old GS driveshafts
    2. a 12a turbo would fit, but there's no way you could squeeze in a 13b.
    3. plenty of mods such as...

    - a gs 5 speed box, so a bit of firewall hacking had to take place;
    - an adaptor plate to fit it onto the motor
    - flywheel had to be machined and redrilled to fit on the 12a's crankshaft
    - the plumbing of the hydraulics had to be altered
    - two radiators for oil and water had to be fitted
    - better discs to survive the heat of the motor
    - better clutch with more bite

    ... and that's just the tip of the iceberg. it's a very costly exercise to say the least

    Nice! How does it go compared to a 1220cc GS?

    The rotary sits well forward in the engine bay. It's easy to see why the Birotor had it's engine tranverse mounted.

    hehe. The engine is actually sitting forward of the spare tire. Where the oil filter is would be basically the back of the engine (mounted on the end plate). The oil filler just forward of it would be centre plate between the two rotor housings. And the dizzy is at the front of the engine.

    For a pretty much stock standard 12A, it's double the power of a standard 1220 GS flat four. 100km/h in 2nd gear was something the 1220 couldn't aspire to

    Default Can't see the Pics

    hi,

    Great idea - but the pics won't come up for me - is it my config, or have they not come through for anyone else?

    Love the idea, might be an interesting alternative to my CX-Rotary conversion concept - the question is then how would I also fit an Air-Conditioner to make it a Year Round all-weather car...

    Do you have a Website with PICS on it?

    thanks

    speaking of spare tyres, how safe is it to have a spare tyre in your engine bay. I couldn't see having one in there would be a great plus if you had an engine fire, as rubber seems to burn quite nicely as well as creating a whole lot of smoke

    There's a fire extinguisher just under the glovebox for those embarassing situations. The tyre under the bonnet is purely a cosmetic thing for the photo shoot

    Orestes - It was done with most of the old cits - and anyway, if you have an engine bay fire, you're going to get smoke regardless.

    CXs and SMs love a good bonnet fire... any car that has a carburettor close to the alternator. It just adds to the excitement!

    Jim Reddiex once had a rally GS with either a D or CX motor fitted. Pretty tight fit!
    I remember an 1100 GS got second outright in an ARC round back in 1973, so they were pretty quick even in standard form.

    I don't know much about the CX but the alternator on the SM is miles away, it just catches fire for the same reason most Cits do....the fuel hoses fall off!

    Stalled,

    A 13b will go in if you cut and shut the front panel and bumper to gain an extra 2.5cm. The heavier GSA drive shafts would probably be a good idea but don't apear to be a necesity. An uprated clutch is a must with the 13B, 12A turbo or extend ported 12A. A CX front torsion bar, early D spheres with the dampening washers and lower suspension arms "adjusted" to provide some postive camber are ways of taking care of the handling dept and the extra weight.

    Chris.

    This car is for sale, by the way- if anyone is interested. Any serious offers are most welcome.

    For some reason unbeknownst to me, the photos don't seem to show. Please feel free to pop me an email if this is the case.
