Turbo sizing

["Turbo-T"]

Why are some turbos started off as "TA, some as "TE, some as "PT"....???

TA has a stock style inlet bell, basically where your MAF pipe attaches. The TE's inlet would be like your TE-44.

Now days, most are all TE style, so they are PT for Precision Turbo.

So is PT like a "newer" version?
