TME TD05HR 20G (!!!) with 10.5 turbin housing

I have been offered a brand new TME turbo but with a 20G compressor wheel matched/machined TD05 compressor cover (turbo is from the US)

Anyone had any experience with this turbo...results?

Im hoping the 20G wheel will give the car better top end - i think this turbo is 650cfm.

Ive been researching this turbo as it will be an easy install (i believe same oil and water lines, downpipe etc) but still give a good increase of power over my standard E4 turbo.

Thoughts please.

TBH it's not a common conversion over here so you might struggle for info. You'd probably be best to ask the same question on evolutionm.
