Sadly don't have a Morgan at the moment but still lurk on here. Bought my 2014 GDI Plus4 new. I feel the earlier non GDI Duratec would have been a better buy because much more tuneable. Eventually I tossed out the n/aGDI engine and inserted a Focus ST turbo motor (loads of torque and 270 bhp so went quite well). On the injection question the answer is easy -- change to VTA (vent to atmosphere). Very easily done. I did this from new with the GDI and the inlet tracts and the inlet valves backs remained clean as a whistle. I do it now with all GDI cars and with my Beemer 340i (same engine as the latest Plus six). The Americans even do a kit for it. Hope this helps.
