Put it (copy and paste) in the right place (like here under this post).
The JWT is the only turbo application for the Z32 that uses a real GT28RS compressor housing (to my knowledge). It requires quite a bit of modification to do it and I use that to rationalize the additional cost in my mind. What it boils down to is the amazing gt28rs compressor map is compromised with any other housing. I learned this in the last couple months. I hope that helps you understand this change in plans.
