Default Oil pump and damper @ 300rwhp?

Getting ready to finish up this deployment and start my build in the next month or so. I've already got most of the build parts waiting for me at home. The questions that I am still trying to answer are:

Should I consider the boundary billet oil pump gears, or just replace it with a new OEM piece?

Should I consider adding a Super Damper?

Price is my only real deterrent to either of these, but I put a high value on doing it right the first time; so I want this to be done right, but I'd prefer not to throw money to the gutter. Here's the information you'll be looking for to help me out:

Currently on the car:
'94 A-pkg
'00 Head
FMII Hydra kit (gt2560 w/550s)
FM 3" Turbo-back exhaust
FM Stage 2 clutch

At home, waiting to go on the car:
MS 6-speed
Mazda Motorsports new 3.636 R&P
Supertech 9.0:1 pistons
Belfab Rods
All new ARP hardware
190lph HP fuel pump
Hydramist W/I kit
Other misc stuff, incl FCM Setup, coolant reroute, etc.

My end goal has always been 300rwhp, though I'm not going to be upset if it puts out quite a bit more. I suspect to increase power much more, I'll need bigger injectors and a bigger snail.

Car is my daily driver when it's running, likely will never see a drag strip, with potential for a lapping day or two in the future. Mostly autocross and enjoying driving.

Do the BE gears for sure - they are hell to install later. The ATI damper isn't required at 300, but it's a good idea too - it's on my to-do list.

I can't see any reason (aside from cost) to not use the Boundary gears and ATI damper. When building a powerful motor, the cost seems minimal given the consequences of oil pump failure. If/when I'm ever making enough power for a built motor (and maybe before, because I'm a paranoid freak about popping a motor), you can bet I'll throw in both of those pieces. The damper is something that I'm planning to do ASAP.

I'm doing both and not necessarily shooting for much over 300. but then I might. And I only want to build the motor once.

and I got my damper 2nd hand from someone in the original group buy so it was cheap.

thank you for the input, much appreciated.

Ill be sure to get the BE gears in this build, and probalby the damper. I just secured a job post-deployment, so I've freed up some extra dollars for a little while.

Thanks!
