Are the Comptech billet oil pump gears worth buying?. Anyone ever seen a failure with stock gears?

As with so many things from CT, the price seems excessive for what it is, limited production or not. Not that the protection isn't worth it, I'm just looking at how deeply they gouge you for it.

I had a 94 engine seize due to oil starvation (high rpm at extended high g left hand turn) I will not drive the NSX hard without the CT oil pump gear, I also recommend the hi-cap oil pan dali sells also I dont have it on my 97...yet.
Maybe woodwork can shed some light on this, but a Honda source told me the 3.2's were re-engineered to prevent this as Honda noticed this happening to a number of NSX's..I am not sure I am buying into this but its what I heard.

Reading through this it just sounds like the gears are weak for over-revved engines. OK, I can think of other engine parts that can cause significant damage too in that scenario.
Does anyone know of gears that fractured and failed for a non-over-revved engine
Also, has anyone ever had one of the aftermarket oil pump gears cause problems
Has anyone done something along the lines of re-working ("porting") the OEM oil pump?
Yep, the NA2's are stronger.
IMO, if you're not driving your car balls to the wall, you don't need these reliability upgrades. If you are, get as many as you can afford... The NSX wasn't engineered to be driven balls to the walls, every time..
Yes, Dali offers a wider gear (and therefore housing), that increases oil volumetric flow rate by ~17% with no drop in pressure:
I think everything is identical, even the same engine bearings.
No insult intended, but our lay discussion is somewhat academic.
