if your doing it get the bigger comp housing, it will be laggy either way (so you may aswell have the better comp cover), but kick hard when its up in the revs
If you fit a TD05 exh housing with the 34mm door & dump & factory suport bracket, you can use a small 16g one day or a sucking 60-1 the next day.

My mate just chucked a Kando (Kinugawa) td06 25g on his rb25neo with some e85 and bigger injectors and made 380rwkW @ 20psi.
The turbo seems to come on boost pretty quickly, pulls hard and is quite cheap.
Im running a td06sl2 25G with a 3 inch anti surge cover on the silver evo3.
The motor is built with stage 2 crower cams etc and a plug in vipec ecu.
On 20 psi it has made 276 kw at all 4 and makes great boost early etc.
Its making full boost by 4500 and pulls all the way to 8000.
These are a great value turbo.
