Upgading Fuel Delivery System.

Post by Adam Archibald »

Ok guys I have some questions. This Thursday I will be starting to
upgrade my fuel delivery system. I am doing this because I will be
placing a larger turbo in the car and increasing the boost past 13 psi. I
am also under the impression that with the car over boosted to 13 psi the
stock fuel pump is too small and the car is already running lean. Here is
what I
am considering for Thursday.

Holley 255 High Pressure Fuel Pump.
AEM Fuel Pressure Regulator.

Later down the road....
550cc injectors.
Engine management system.
Bigger turbo :)

Once the new parts are in the car, it will then take some runs on the
dyno. I will be placing the fuse into the FWD/AWD slot in the engine
bay as the dyno is not AWD. Has anyone run their car on the dyno using
this FWD trick? What size fuse should I use?

So let me have it!

Current mods on the car so you know background.
STI engine mounts
IC off 95 WRX
2.5' Custom exhaust with 2.5' down pipe, high flow cat, reactive muffler
Boosted to 13psi, Autometer boost guage.
KYB struts with Whiteline Legacy Select Springs
K&N filter (wow feel the power :P ) with 'snorkus' removed
17' primax rims covered in Falcon GBR tires.
and yes it is still a crappy auto :(

FYI the australian RS Liberty Turbo stock fuel pump puts out a little more than 150 Litres / hour.(39.6 us gallons /hour) This is fine for 17 psi boost, which i run at.
cheers, Rod .. in oz
