t25 turbine wheel trim?

[BluntyR5GTT]

Just wondering what trim wheels any of you guys running t28 turbos use as i will be upgrading the turbine wheel on my turbo after this dyno day on sat. Currently running a t28/t2.63

The wheel from a tomcat turbo seems to work well although if your changing the size of wheel i think you'll need to change core too to T25 size due to the shaft being T25 (wheel is part of shaft).
