TB are good for power but bad to fit and set up on a 350Z
1, stock ECU wont run a car with ITB
2, servo vacuum are low
3, unless you use a ECU that runs DBW your need to fit a throttle cable/set up
4, fitment under the bonnet if you run a air box (which is a must for road car)
just fir a SC or a cheaper turbo kit which we are developing
Alloy cam covers , just use the Nissan Pathfinder Stock Alloy covers , off the shelf part.
