Does anyone know the gearbox ratios for 1.6 and 1.9 turbodiesel Audi 80's?
Thanks
Hi Arthur
I got a free 1Y engine and I plan to put it into a 1.6 Audi A4 or Passat. (they have throttle cables). I don't know what gearbox to get but I know there were Audi 80's with 1.9 diesels both straight and turbo and the 1.6 td. I have a box from an A4 TDi but I think the ratios would be wrong. I Intend to convert to turbodiesel in the future. This is a Bushmills and Stella in the shed winter project. Any light you can shed would be much appreciated.
Hi there, first stamped on the top of the gearbox bell housing is the gearbox type if you pass this on I will probably tell you the ratios. I have just taken the gearbox of an early a4 diesel with the if I remember DHF gearbox. The box in the audi 80 tdi is the BAA with an overall ratio of 2.656 : 1 the dhf is almost the same and gives the speedo 1mph higher. ps the elsawin 4.0 dvd is on ebay very cheaply, might be worthj a try, all the gearboxes of this era are there and a lot more info. Come back with the gbox number and I will reply with the ratios. Arthur
I'll get the code off the tdi I just want to know if the older boxes had different rations. 1st and reverse would work :)
Thanks Arthur my gearbox is dirty I has assigned the cleaning to boy wonder so i'll have the info later on. I don't think the 1.6 petrol box would mount to a diesel, I recall someone telling me this
Right here we go.....,.Audi were aware that the BAA gearbox fitted to all audi80 tdi were fragile, poor bearings, with the release of the a4 this was put right??? with poly bearings, so the best gearbox for you will be from an early a4 1.9tdi about 1995 to 1999. there are a number of variants with various gear ratios mid range but all have the same ratio in 5th which is what you want, or recalibrate speedo, not good. So look out for a CPC, DHL, DVS, DWE all are the same overall ratio, you may find a DHF which is slighly less overall ratio than the BAA but will also fit and you will not really notice the difference. Audi use the same casting for all these gearboxes ie 012 with odd variations in mounting but all the bolt holes for the old fixings are still there. The !.6 petrol gearbox will fit mechanically but the overall ratio is too high, petrol engines produce power at higher revs. Hope this is what you want. will not be back now till Monday
I just read this and want to make something clear, what you are looking for is an overall gear ratio when in 5th gear this will include the gearing in the differential so that speedo is correct when normal driving. Even in 4th and 3rd you will not really notice any difference. Just to put your mind at rest
Thank you Arthur
My thinking was that the 1Y I have is the early version 64 bhp so I was concerned about the engine not being able to make the car move. I remember a guy selling an escort years ago 1.6 ghia with I think a 1.1 engine on the 1.6 box. It was an awful car to drive. I intend to get this done then get a good AAZ and fit an AHU turbo next year
thanks again
