Hi NiCkeL,
While the CT26 won't bolt straight on, it is the easiest to make an adapter plate to bolt up to the standard 3T-GTE manifold, & it does work very well.
3T-GTE
The CT26 off the 7M-GTE only requires the mounting holes in the turbo to be slotted a few mm, no adaptor plate is required. You do need to port the manifold out to suit the new turbo for best results though. There were pics posted up somewhere on the forum of the work required, was it TE72_Turbo who posted them?
