All HPT 850's received TD04HL-15G turbos, with stock boost for turbo and T5 models set at 9.6 psi, and T5-R and R models at 10.5 psi (stock hp are 222 and 240, respectively). (The European 850R received a 16T turbo)

All HPT 70-series cars received 16T turbos (with the exception of the V70R's, which received 18T's in 98 and 99, and 19T's in 2000). Not sure on stock boost setting, I'd assume it's around 10 for the T5's and probably 12.5 or so for the R's.

The 98 v70r comes with a 16t stock just FYI. The 16t Definetly spools faster but my feeling is the 16t with a tune performs stronger on the highway. This is my personal experience so I prefer the 18t in our big Utah highway mountain passes where it's helpful/needed.
