Message The rb25 and 26s have:
3 more crank bearings/journels
more rigid block
can handle higher revs
Cools easier
Smaller in width compared to the VGs allowing more options with turbos.
Better flowing stock exhaust manifolds

The VG30s give you a shorter engine in length and height (except for the tall intake manifolds)
Lots more tourque because of larger pistons
A growling deeper exhaust sound

the VG20s give you less of everythin...
