So it is better to keep the 2cv6 gearbox (8/33) which is working well, I guess... Put some bigger tyres on it 145/15 or 155/16 for instant lower reving (don't trust the speedo then) take gps.......... _________________ Russell wrote: Hi Geo, you've been one of the sites biggest attractions in recent years.

Well, 2cv6 gearbox, at 100km/h 5200rpm, same box with 8/31, at 100km/h 4900rpm, and with GS1220 (longest ratio) box, at 100km/h 4100rpm... Very nice for ears, and goes quite well with AM2A (Acadiane) engine. Haven't drive yet over 135km/h, but it was still going strong at that speed... My engine is not tuned, "only" fuel injected... And it doesn't burn clutch, only slight slipping when shidt 3rd to 4th at WOT. BUT, I don't recommend this with carb engine, then clutch will burn!

Yes, and no. With normal engine with carb, I wouldn't even think to put GS gearbox, as I said. But, with 602 IE, there isn't any problem. There is lot more torque at lov rpm, so there isn't any need to rev engine, not even at hill! I had same gearbox with Visa engine (over 15 years ago), where was rised compression, and with that engine there was enough power to handle long ratio box...

It won't be easy to find a mechanic who assures me that the diferential 8/31 will fit perfectly in the 2cv6 box. Meanwhile, I won't touch the one that is currently working on my 2cv. In case things go wrong I will always have this one...

It fits fine put the 2cv one in the Am/Dy box and you have a high ratio and a low ratio box _________________ Kissing the Lash "Any advice of a technical nature is given on the understanding that I've actually done this shit, not just read about it in D*lly club mag some time ago.
