Don't know never seen a npc one, depends what the plates look like. If they are a puck style it will be a pain to drive, if they are full face then will drive similar
Nismo copper mix twin plate all the way, drives like a factory clutch and know of one holding 475 at the wheels, including massive launches and been in the car for 8 years
Also have the added bonus of not exploding
Just remember when looking at a 300zx is 90% of them have seeious electrical demons and most of the water hoses are perished and require replacing. They are also very light in the rear and have trouble with traction at standard power levels.
Also they are harder to work on then a gtst (won't say skyline cause the Gtr is a pain) and good ones may be harder to find
