Re: difference between v8 and 6 t5 gearbox
As honer said, the input shaft length is wrong as is. The I6 box also has slightly different ratios to an 8's box...
From what I've heard, you need to be very careful getting boxes from wreckers etc second hand. A lot of the time a 6 box will be sold as an 8 after the input shaft has been altered, and just about the only way to tell is to open up the box.
Plus I imagine there is very little in the way of warranty ( I know some ppl here have been burnt buying second hand t5's that only survived 6 months ). Reco's are expensive as well . . . :/
