Fuel system or pulleys = more power?

[sprayedlude93]

I am thinking about getting one of the next set of mods. Either a pulleys set from UR or a fuel system, consistion of AEM Fuel rail, fuel filter, fuel reg, 440 RC injectors and a Walbro in tank fuel pump. Which one will make more noticable HP for me?

My current mods are as follows:
JDM H22A
Injen C.A.I.
Magnaflow Cat-back
DC Headers
Magnacore Wires
NGK Plugs
Msd SCI box
Msd SS External Blaster coil
Aem Cam Gears
Eibach sportline lowering kit
Toyo FZ4's

if i am correct, if not then ignore me, but uderdrive pulleys can only add up to around 37 hp at the wheels, so i would have to say the fuel system.

37hp more from an underdrive pulley? where'd you get that info from?

anyway, based on thsoe mods, i see no need for you to upgrade your fuel system as such. especially 440cc injectors?? that'd dump a whole lot of fuel, more than you'd need. a lot more. good luck passing smog with those.
you have to keep in mind, the more fuel you add to the mixture, the more air you need to add to it as well. i don't see an upgraded fuel system being all that beneficial to you at this point for the price it'll cost you.

i would go for the pulleys before the fuel system if i were you. the stock fuel system is sufficient for the mods you have on your car.

i agree. you're just gonna run the car rich, IF you were turbo'd or supercharged i'd say go with the fuel upgrade, but chances are you would already have that stuff installed if you were turbocharged because a turbocharged car would run poopie without it. no point really adding that stuff without a fuel management system or like a hondata or something to control it anyways.

some import mag had their pulleys rated up to a 37 hp gain, but then again they prolly put theirs on a shity as geo and used those results. by the way tho this site has unorthodox pulleys for 8-14 hp gain http://www.importperformanceparts.ne...ts/ur_ur3.html

there will not be that much of a gain just from a set of underdrive pulleys. i am sorry but that is just a false claim and is pretty far out of line as far as i am concerned
