Gearbox - will a hdi box fit a TU engine? - swigham - 16-11-2012
Anyone know? is the linkage the same? - i'm sick of the ratios on the petrol box, doing a lot of motorway miles and sitting @ ~3250rpm @ 70 mph is annoying me.
and as i'll be changing the clutch anyway.....

simply no. BUT....a gearbox off a 1.4/1.5 Derv 106/Saxo will fit the 1.1/1.4 TUs. Noit sure on the 1.6 though. I put one on my 1.1 106 (back in the day) and got the revs to sit at 2750rpm @ 70mph IIRC

yeh a gearbox off the above will fit but still wont give you better ratios unless you go for the 1.5D box. Are you really willing to have crap gear ratios on the bottom end just to run lower RPM at the top? Also just for the record my 1.8 was much more efficient on motorways than my 1.4 so a smaller engine isnt always more efficient.

With a angle grinder, welder and great big f*cking hammer, yeah. Otherwise, no, but there's loads of different ratios for the TU boxes.

Cheers guys - nice bit of reading up to do then, yeah i'll hapily put up with a crap bottom end, doing 100 mile a day roughly, of which 90 are motorway.
