oops, 148HP was the L6 with aluminum head that came in the 86 300SDL
the turbo in the OM617 was too small. at high, sustained rpms it works like a blow drier and without intercooler your mpg will suffer.
the earlier (70s) burbs came with the 350 IDI which GM put in their vans as well. years later in the newer model they fitted them with the 6.5 IDI, they might have also used the 6.2 but i am not sure. yes pseudodiesels can be terrible as in the case of the 350, but quite good too as in the IDI VWs.
