New Updated Starter
 

What year did the new updated starter come out? Do any of the series I's come with it from factory? I heard it came out in 2007, or is this wrong?

2006

So since I have a 2007 RX-8 I should have the most updated starter already installed?

2009+ have superior starters. But you do have an upgraded one, compared to the earlier models.

My Mazda dealership is claiming I must upgrade my starter to an updated one so it improves my compression numbers. Without the starter they won't process my warranty claim for a new engine. Does that make sense?

Your starter could be going bad, hence they want to to upgrade. However, you can either test your current starter, you can get a used upgraded (06+) in good condition or get a new 06+

The starter doesn't change compression. If it's failing and turning too slowly to start the car, fine, but that's different from the engine warranty claim.

They said there's nothing wrong with my current starter they said "it spins faster".

This is true, and I should have brought that up.

However, it does need to achieve at least 250rpm in order to operate minimum crank speed

Haha ok that's just BS. Tell them to do their job
