The problems related to the combined Nissan crank angle and cam angle sensor running off the cam.
Link in CH CH had to modify the computer to stop misfiring.
The plugs were firing but not necessarily when they should have.
There was a possibility of destroying the motor--
So the shop had it for over a month and were pleased to see me take it away.
It's interesting that although the car has high power and light weight ,it's nothing spectacular.
Driving back to my workshop I was wondering how to give it some real power--yeah right
