mgzr 1.4 auto conversion

animalwildchild · 22-08-2020, 10:55

My wife has had an MGZR mk1 since 2008 it was a 2002 model running an r65 gearbox, she doesnt want to lose her car but it is getting difficult for her to drive, would the 1.6 auto gearbox and attachements (flywheel, autoclutch)fit on the 1.4 engine

They would physically fit to the 1.4 (although I think it is a bit more than just fitting the Stepspeed box and its directly associated parts

).

However, the Stepspeed gearbox does sap a lot of power, and I think she would find the ZR very sluggish if you kept the 1.4/105.

Perhaps better to swap the entire engine and gearbox for one from a ZR Stepspeed (if you can find one - they only built a few hundred!). The ZR Stepspeed was a 1.8/120, but the CVT transmission dragged the performance of the 1.8 engined ZR down to little better than the 1.4.

It may be worth keeping your eye out for a ZR 120 Stepspeed - a lot simpler than doing the conversion.

Definitely better off looking for a complete car
