It's kind different. I think the biggest difference is the hydraulic internal slave cylinder. Beside this (compared to a 350Z of a friend) the 370Z trans has a speed sensor on the trans itself, something that the 350Z doesn't (based only on what I saw on the 350Z trans --> I dont know the year).
And yes I'm using an adapter plate together with the Tilton clutch and ZSpeed heavy duty slave cylinder.
