Trying to decide on whats best for me to do on a "fuel upgrade"

currently have a single walbro and a JDM aristo in my car with the 440s, yuck.

I am tossed between buying another pump, new rail, regulator, injectors and such.


or do the drop in style injectors, regulator for the stock rail and of course another pump.

my goal will eventually be about 650hp so I just wanted to get some opinions.


(for reference, my current drag car is a civic with an aeromotive A100 pump, 1600cc injectors aeromotive regulator, -10an feed lines with -8an returns)
just trying not to get AS elaborate with this setup and use some smaller injectors that have less dead time and are a tad more street friednly.


Thanks for all the help guys

i'll get cha started.
the injectors almost directly represent maximum horsepower on these motor. AKA 550 injectors will max around 550whp.

so if you want 650, just divide 650whp by 0.80(to make sure you aren't always maxing the injectors).

as far as which route to go, not sure about oem line resitrctions, so i'll leave it to the next guy

Thank you, im just wondering what everyone does as far as the route to go. I mean does everyone just ditch the oem rail and side feed style and go aftermarket rail and regulator or is it still okay to drop in some larger sidefeeds like the 850s, and drop a regulator on that works with the stock rail.

Thank you for the information

i'll give you first reply to that too.
I went new rail, lines, etc. . .

It seems MOST people use the MKIV Supra 550cc injectors, but with a 650goal, you can't get away with that.
