Hi All,
Time to start a new project. Actually for a friend.
He has Just done a motor conversion on his Truck from a supercharged 999cc Suzuki engine to a 1400cc (CR14) vvti Nissan. Still running the Factory ECU and DBW setup. currently causing a few issues.
It has a few challenges going forward so I thought I would float them out for your idea's and comments.

Attached are the Crank and Cam triggers.
Crank trigger looks like a 34 tooth (notch's) trigger wheel (hall effect pickup) with 2 missing teeth. 180' apart. Not ideal as it will not easily divide by 360' . Plan to make a new cutout to make it at 34-1. But need to split the motor and gearbox to make sure the picture is accurate and they are equally spaced.
So a Non 360 deg trigger will be the only choice, unless I make and install a new trigger wheel on the crank ie 36-1. but would prefer not to unless i have to.
Has any one had any experience with this trigger pattern. i have read it has a few special requirements.
The Cam is a real fancy one. number of teeth = current cylinder to fire (Also Hall effect). Don't think there is any thing for that one........
We will be replacing the DBW throttle with a SR20 cable operated one (as its on the shelf) and TPS
COP factory smart coils
VVTI - Open loop to start with until we get the Cam trigger sorted.
And a KiwiEFI ecu (as I live in NZ where they are made) One of his fancy ones
has MAP and IAT on current engine in loom. which will get reused.
Thanks in advance for your thoughts.
