The IMS isn't rotating at crankshaft 7.000 rpm. The camshafts are rotating at 3.500 rpm when the crankshaft is at 7.000 rpm (4 stroke engine).
So because the IMS seems to have the same gearwheel diameter (didn't count the teeth, so i don't know exactly) as the cams i would say it rotates at around the same rpms as the cams and not as the same rpms as the crankshaft.
That means you have to look for an extreme high speed capable IMSB.
But it's important to take a look at the individual bearing specs.
I also would go with a sealed version.
And please remember that an engine in a car with acceleration, deceleration is not an engine on a engine stand. So if you have around max. 1g acceleration in changing directions, there is engine oil everywhere,
And if you want to reuse the center bolt, don't pull it with the cheapo "standard" tools some people like to sell for a lot of money. They are only OK if you replace the centre bolt anyway.
OK, enough IMSB talk for today.
Think if you do a good research you'll find enough information to get everything right.
