The M178 MB engine is pretty tight with the turbos in the V but the integration of the electronics and ECU stuff must be a BIG job.
Not to mention the cooling challenge when packaged in a Morgan with their small frontal area and limited room for large radiators & intercoolers.
According to an interview with the MB program engineer in charge of M178 and the related M133 (the derived single-bank 2.0l inline four) the biggest development challenge for the outputs these engines provide was heat management and cooling. Pretty marginal in their OEM application according to him (and likely to require a back-to-blank-sheet approach to evolve them much beyond where they are now in terms of bhp/l). Be interesting to see how/if Aston Martin can raise the bar with the customer M178.
