Will a 6 speed box from a mk4 tdi fit into a SDI without any problems?

I presume you would need to change the short shaft also.

At 68bhp would the sdi have the power to take advantage of the extra cog? Just a thought....I remember having one and she was very underpowered in 5th

No idea to be honest, I was asked the question myself so passed it on.

He said the van is doing 3k at 60mph in 5th.

There is a reason why they are geared so low, it is because they have no power.

I've seen threads on other forums maybe vortex/tdi/edition about swaping just the 5 gear cog out from a mk3 for a t4 or t5 one to change the ratio and lower the revs a bit.
don't know this is any help as its for passat tdi
