there seems to be no weak points as such, but can still go wrong due to build/tuning error as with any engine.
very tuneable, with the ecu being the main restriction limiting the rev limiter at 6200rpm and not seen the results for one with standalone ecu and a proper cam, its yet to be done.
safe tune, mine was quite happy with 23psi, 230bhp/lbsft which is about the limit of the std (scoff fettled) ecu. about 18mths of daily abuse, pod etc just requiring the odd adjustment and usual service once the conversion niggles are sorted.
for me, have been volvo for many years, in fact, only had a c1j in my first gtt which spent more time in bits than on the road.
