The MD321 is a specific type of turbo, based on using a Garrett GT series ball bearing core.
P18, & P20 refer to the two sizes of Subaru IHI exhaust housings.
In context, the MD321 uses a modified version of the smaller P18 exhaust housing, which gives better spool up, & response than the larger P20 exhaust housing.
