I have a 1993 200tdi automatic. Changed from a ex military S11A that i purchased in 1981 and sold in 2005. That one i fitted 2.5 tubo, Disc Brakes and Parabolic Springs, made a big difference to performance from the 2¼ lump that was fitted.

 

Trev, welcome to the boards. Sounds like you get into the tech stuff about as much as Disco Mike. You two would prob have a blast talking Rover tech over a cold beer overlooking a beautiful ravine you just took a treacherous trail to get to. Just don't go there without me!!
