   how much acceleration lost with a vtr gearbox in a vts? will have 2" decated pipe to magnex back box with no centre silencer if it makes any diference.

   slows you down a bit in terms of acceleration but you gain slightly in top speed. also takes the vts engine out of the powerband. wouldn't advise it unless you were getting the vtr 'box cheaply and were desperate.

   I wouldnt. As sean says, it not worth it as itll detract from acceleration a bit.
   
   Just get a cheapo 1.1 box, similar ratios to a VTS box anyway. If youre worried about mpg on the motorway, just change out 5th for a diesel of VTR one.

   can you change the 5th? not arguing i'm actually curious as to whether this can be done as i'm led to believe it couldnt?

   Yeah you can change 5th, dead easy actually. 1st to 4th are part of one gear cluster. Two mins I think I have pics.

   Not the best of pics but...
   
   On the second pic, you can see the one-piece gear cluster, its the lower of the two. The two splined parts at the ends of the shafts, on the right, is where 5th sits. Pop it off with a bearing separator and you can change them about.

   the vtr box wont make you drop out the power band on gear changes, as all the sport models use the same cluster the rev drop between gears is the same.

   Changing 5th gear, is actually really interesting.

    gabb - just thought, vtr uses same cluster as vts, so you would need to swap it for a non 'sport' 5th gear.

    Thats weird, the VTR boxes Ive had apart have had taller 5ths, forget the tooth numbers, but equates to 0.767 instead of the 0.85 of the VTS box.

    fit an S1 106 rallye box if you want out and out acceleration, but why do you want acceleration in 4th and 5th gears?
