Here's a question for all you engine techies out there. I would like to know the diamter of the biscuit shims that sit ontop of the solid lifters in as many Nissan engines as people know.
The reason is I am looking to see if there are any that are interchangeable with the March. They unfortunately stop at a whimpy 2.98mm and are approximately 27mm diameter. I have some high lift cams to fit but because they hare of highlift type their base circle is therefor reduced, pushing the clearances out of the standard Nissan range.
If people know of any companies in the UK that can make these types of shims to order I would be most greatful.
I am trying to use tophat valve shims to fit under the current lifters but they look as though the thickness range is not in the correct range to work with the standard lifters..........you can see my problem.
Anyway, any help will be most......err......helpful
