Z1 VRX60B vs?

[5thZ]

AMS isn't making a kit to my knowledge but CZP is with the Garrett 550's but I don't know about the torque curve they said it would outperform the Z1 turbos in terms of power though

i used to have 550s on my 350z back in the day, kinda small

Interesting that CZP said they'd make more power than the 60s or 70s then
