Quick rundown on what pumps you should be looking at for your cars.
1200psi 1.91 GPM
Min-Max times 1.2s
Recommended versions 2010-2012 from Mazda 3 & 5. Pre-2010 had water ingress issues. 2 Connectors on the pump means its the 10-12 variant, 3 connectors, means pre-2010 variant.
Average cost at junkyard: $50
1200psi 1.91 GPM
Min-Max times 4-5s (Depends on specific years)
Don’t recommend. Slow to respond, over priced compared to Mazda pumps.

Charger / Jeep
1700psi 2.5 GPM

Recommended, but comes with a terrible design for a high pressure fitting.

You can always go overkill on the pumps, but there’s not much use if you don’t need it. Pumps will not blow out your seals, as they only produce flow, while the rack and other restrictions are the ones that create the pressures. The recommendations I have added there are based on cost vs need. If I recommend a Dodge/Jeep pump, its because that style of car will probably need it.
