Since the maximum rpm is now 8500 x sqrt (144/122) = 9250, 8900 is seafer than 8500 with the stock spring. I did also the complete calculation (more complex) and the result is the same.

I never changed the oil pump, and yes I feel a little bit affraid about it, I broke one on my Honda engine last year (H22A running at 8000 rpm on vintage Lotus Europa 69).

Best

P.S. I am living Montreal downtown.
Marc,

How do you like the rev limiter? One of things that we really like is how smooth it is compared to the stock limiter. You can actually drive on it without upsetting the car (although it's never recommended). You can also differentiate fuel limit from spark limit.
