VT2-650 was just released, im sure you will see info posted as customers begin to receive their kits and get them installed. The 650 looks the same as all other VT2 kits. The changes made to improve performance over the 625 do not affect the cosmetics of the system.
This thread contains a video and dyno made by Arkym of their project car running our VT2-650.
