FWIW: all the above plus the Thor got
- a much improved WABCO brake modulator
- upgraded ZFHP24 gearbox (vs HP22 for GEMS).
- new ignition coils -2 blocks serving 4 cylinders each rather than 4 blocks serving 2 cylinders each for the GEMS. THOR ignition coils are also a LOT less expensive to replace vs those for GEMS.
- much better designed /more reliable Crankshaft Positioning Sensor ...no chance of fouling the ring gear....
- 4 pinion diffs front and rear (later THOR models)
plus a heap of other small stuff which adds up to an allround, more reliable better package
BTW ...when I got mine 3 yrs ago 100k kms on the clock AND the BECM...the (wholesaler) sales bloke ...(yep I found it on the web...) mentioned the THOR upgrade and said what an improvement it was... thought he was guilding the lily until I became a student of RRs and literally pulled it apart like a Meccano set... :angel: now I have the RR virus and ... am discovering all sorts ways to rationalise draining $ from my walllet :(
