The MR2 mk1 had the 1.6 16V 4AGZE which was supercharded and iron/ally. Don't bother its old tech and very heavy with all the cast iron bracketry and inefficient Denso blower.
The Mr2 mk3 had the all ally 1.8 1ZZ-FE. Not too heavy but only about 140BHP and quite bulky like most of the all ally engines.
The blacktop 1.6 4AGE 20V engine from Japananese imports only is one of the lightest and most compact small engines (excluding bikes of course) you can fit. 150-160 BHP and around 90kg if you include the manifolds and standard individual throttle bodies (fitted as standard). Due to a light flywheel and lightened internals compared to all previous 4AGEs.
However you will still be hard pressed to beat the Rover K series engines for lightness. Again a bit more bulky due to the all ally design but about the same or lighter than the Zetec SE and up to 1800cc.
I found the very early Sierra diffs are about the same weight as the Freelander diff at about 17-18kgs. All later Sierra diffs I believe are at least 22 kgs or above. The only draw back is the driveshafts are unique to the early diffs as the input diameter is smaller for the driveshafts.
