Superduty pedistal is shorter, and the turbo bolts from the top
OBS is taller and the turbo bolts from the bottom.
#9
Completely differant turbo...
There different because of 5 years of development... 94.5-99 are more or less the same, then 99.5 they went to the newer turbo...
The E99 is very similar to a OBS turbo, but with a .84 exhaust housing.
