I can't find anything that uses the same injector, 03-04 Volvo C70 with the Turbo 5 cyl. Bosch part # 0280155968 These are only 42# injectors and I can't tell the EV1 from EV6.
From what I can tell it seems the 8.1L engine uses 42# injectors but only if it is flex fuel and they seem to be much shorter and are referred to as Multec 2 connectors.
As far as a MAF that connects directly to the 04+ cars I haven't heard of anyone switching out the stock MAF for a larger one, I can't find any info on that either.
