   The gearbox in my vtr was replaced by one from a 1.4, will this effect the performance much at all does anyone know?

   Not much at all mate. The 1st and 2nd gear ratios are very slightly shorter. Final drive is the same though. The 1.4 furio gearbox has a much weaker diff though so take it easy in 1st gear especially.

   The diff is included in the gearbox itself mate. I did in three 1.4 diffs. When i picked up the one i have on the car now from the scrappy, the bloke said the reason your doing them all in is due to the shit you're giving it in 1st. Just don't do two many wheel spins or you'll end up with more smoke than you bargained for lol. Yeah 1st and 2nd you'll notice a slight difference 3rd 4th & 5th are exactly the same.

   do a search on gear ratios on here mate if you're interested, someone has done a complete thread on all the different ratios of each gearbox on each different model of saxo and different tyre sizes etc.

   It wont alter your performace atall, will just limit at different speeds.

   CoolC if the ratios are different it is obviously going to alter your acceleration / top end. Between these two boxes there isn't much difference though i know.

   Yeah i know, but it wont alter performance which is what he asked. It will limit at diffents speeds, like i said.
   But yeah as you say there isnt much difference between the two
