T34 is the turbo from an escort cossie
T35 is the turbo from some kind of scannia truck
most people refer to the T34 as a T35, hence the confusion. 99% of the time when people say T35 when talking about cossies, theyre really talking about T34s
i beleive jano was selling real T35 turbos at some point for fitting to fords too which confused things even more
