is a Gt3255e turbo, dual ball bearing?

Nope. There has never been a dual ball bearing GT3255E.

With PTEs turbos, the part number has to contain the letter "R" which stands for Roller bearing, aka dual ball bearing.

Here's an example.
PT6776S = non ball bearing with an S compressor cover.

PT6776RS = dual ball bearing with an S compressor cover.
