jengis 0 Posted March 26, 2009 My 1.6 box is making noises, perhaps diff bearings are worn.... will have to get it off and open it up anyway. I have a 306 XSi box that I could use instead (I have the XU10j2 engine in) but it would be nice to know the ratios before I use it. I won't bother if its a long-legged box. I think 3.79 f/drive??? That would be ideal! Anyone have a clue, even if its just a guess! Cheers, Kev Share this post Link to post Share on other sites
jengis 0 Posted March 26, 2009 A post by ifcho in an old thread included a gearbox/engine chart from a 306 workshop maual. Under "capacity" it gives 16 * 61 (suggesting a 3.81 final drive). So I think I have answered my question! No idea what the ratios are but I'm guessing they would be the same as the 1.6 box. Should suit the engine perfectly! wish I'd chosen this box when I swapped the engines......benefit of hindsight Share this post Link to post Share on other sites
KRISKARRERA 2 1 Cars Posted March 27, 2009 When that engine is in the 405 the gears are fairly long, 70mph in 5th is only 3000rpm or maybe a bit more. Share this post Link to post Share on other sites
welshpug 1,622 Posted March 27, 2009 (edited) unless you have a turbo it may be rather too long for a naturally aspirated engine in a 205. right, a check of servicebox gives two final drive combinations, both 3.68 after that its difficult to be 100% without a code off the gearbox.

jengis 0 Posted March 27, 2009 I know the engine will have been used in a fair few different pugs and citroens but unlikely they will all have the same ratios. hmmm 3.68..... Is that the same as a 1.9 f/d ? A bit too long for my liking as you say. I've tried using servicebox myself but struggled with it. Is the info available under the "free services" (i'm not subscribing) Cheers, for the help. Share this post Link to post Share on other sites
welshpug 1,622 Posted March 27, 2009 quite possible a few other cars would use the same gearset, and yes the final drive may be the same as a diesel, though the gearset may be even longer. if you have the VIN, or the code off the gearbox you can get a better picture of what's inside, unless you want to take it apart...

jengis 0 Posted March 27, 2009 box is in my mates garage, will pick it up tonight. So a search using the code should get me the info? Will try later. Cheers Share this post Link to post Share on other sites
welshpug 1,622 Posted March 27, 2009 on servicebox it may well do yeah. Share this post Link to post Share on other sites
jengis 0 Posted March 27, 2009 (edited) After digging around from various sources but mainly servicebox I'm pretty sure these are correct for the 306 XSi 8v (BE3/5 S1 gearbox): 1st - ? 2nd - 1.850 3rd - 1.360 4th - 1.069 5th - 0.865 f/d - 3.79 Edited March 27, 2009 by jengis Share this post Link to post Share on other sites
