What fuel pumps are you guys using for your sr20det setups?

I currently have a walbro 255lph, but im gonna upgrade, im stuck between the aeromotive stealth 340lph and the bosch 044 300lph, what has been everyones experience with pumps?

Why upgrade? Do you need the additional flow? Are you making over 450hp?

JDM SPUG · 04-22-2012, 09:02 PM

Bosch 044 FTW!!!

i hear shitty shit about the Aeromotive for some reason.

I just switched from the walbro 255 to the 340lph stealth. I ran into flow issues around 375whp on my s13 sr

shootin for 400whp for pump gas/meth, and 550whp for high boost c16

they are two different animals, with respect to how they work and how they should be configured. The Bosch is a great pump but because of the design you need a fuel filter before and after the pump, as the 044 can displace particles into your fuel. It is a tried and true, reliable pump. The Aeromotive on the other hand is quite impressive on it's output readings and doesn't require a fuel filter after the pump. I have run both a dual external walbro setup and a single Aeromotive stealth 340 pump, and I am currently running the Stealth 340.

i was gonna keep a walbro in the tank and run the bosch inline if i decided to go with the bosch, which maybe my route with more research, im jus not liking what im reading about the aeromotive pump

While nothing wrong with the switch, I'm surprised you had issues at that powerlevel with a 255 (unless it wasn't a HP one). Heck a single 255 should be sufficient for 450whp.

O/P, don't forget to consider the line size as well.

My current setup is a walbro to surge tank, surge tank to 044, 044 to 1000cc ID injectors. Should be good for 700hp. Twin walbro's will get you what you need. I think your only choice really is a big external or twin internals. Twin wallys are known to be good for serious power. My buddy has twin wallys running 600+ on pump and 800+ on race.
