WHAT SETS THE NOSTRUM FA24 PUMP APART: 

  • Fully assembled HPFP  
  • 100% Flow tested before sale  
  • Ethanol Compatible  
  • Limited Lifetime Warranty  
  • Installation guide included  

The new FA24 from Subaru is proving itself to be an improvement over the previous FA20, making easy power with basic bolt-ons, but it is still held back by the factory fuel system. This is where Nostrum comes in! 

Nostrum’s HPFP for the turbo FA24 is capable of flowing 37% more fuel than the factory fuel pump. The additional fuel flow allows you to dial in more boost earlier, resulting in a substantial increase in low end torque. Being that our pumps are ethanol compatible, you also have the added benefit of being able to run e85 or blended ethanol fuel. Ethanol is wonderful on turbo cars, as it has a higher octane rating and is less prone to knock than 91/93 pump gas, and you have the potential to make more power as a result. The HPFP can also be installed and driven on without a tune, but we recommend tuning to utilize the pump’s full potential. Our pumps are tunable on Cobb and ECUTek software.  

While the additional torque from the upgraded HPFP is a wonderful thing, most people are looking for more peak horsepower. Pairing our High Flow injectors, which flow x% more than stock, with the upgraded HPFP creates the ultimate DI Fueling package for this platform. There’s no need to worry about secondary injection controllers, filling meth tanks or clogged meth injectors. These are the only aftermarket injectors for this platform that are 100% compatible with the stock ECU and tunable on Cobb or ECUTek. Injector Data and Tuning guides are available upon request.  

Nostrum backs every part we sell with a limited lifetime warranty. All Nostrum products come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.

  • Direct fit high pressure fuel pump (40% flow increase over stock) 
  • Installation instructions

Great for potty training
Size: 3T-4T, Unit Count: 20
We really like these pull ups and they have worked well for us during potty training. They are easy to pull on and off, which is great for toddlers who are learning to be more independent. They fit well and do a good job containing messes without leaking. I also like that they feel comfortable and not too bulky, so my child can move around easily. Overall, these have been a reliable option for us and something we continue to use during this stage.

Nice
Size: 3T-4T, Unit Count: 112
Good pull ups, it could get a little linty but it fits perfectly on my toddler. It stretches which I love. I do love how I could strap and unstrap the sides of the pull up. The designs on the pull up are cute. It holds a lot of pee and soaks it up very well. It’s comfortable on my toddler and the pee and poop doesn’t leak out of it. It is worth the money.

The Fast & the Curious- Potty Drift
Size: 5T-6T, Unit Count: 60
Who knew toddler potty training required both a PhD in fluid dynamics and Jedi mind tricks? These Pull-Ups prove the science part: leak-proof, absorbent, and surprisingly soft. The toddler-psychology part? That’s a battle of wills. Our little one was a die-hard fan of Huggies diapers—too loyal, in fact. We begged, we bribed, we pleaded: “Please, let’s move on!” Resistance was fierce. So we went stealth mode, sneaking Pull-Ups on at night like parents on a covert mission. Credit to mom—she cracked the code and finally got the kid interested in the toilet. Suddenly, the “potty rush” moments became less of a flood and more of a sprint. Diapers were too slow to peel off; Pull-Ups gave our little sprinter the speed boost they needed. They’re soft, rash-free, and practically leak-proof (unlike that other brand we don’t speak of). Pro tip: size up for easier toddler self-removal. The result? A drier, happier kid, less laundry for us, and the toilet finally earning MVP status. If you’re ready for your toddler to graduate from Diaper University, this is the diploma. Bonus: you’ll save money too.

Mom of 3 recommend!
Size: 5T-6T, Unit Count: 14
I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.
