What Should I Buy To Upgrade My Fuel System

[bobert]

Current mods
hks suction air filters
walbro fuel pump
S/S free flow exhaust system
front mount intercooler
apexi power fc
325 fwhp

I am wanting to modifiy my rx some more and I think my stage is to up grade my fuel system (injectors).
Can any one give me a bit of info about what upgrades that are avalible?

You can go for 1600 injectors but these are a bit of a pain to fit if you still have the rats nest due to the custom fuel rail thats required.

Or you could go for putting secondary injectors in the primary\'s to get a bit more fuel in. Either of the above will require a remap.

Third option is 1300 injectors in the secondaries although personally I would not risk these as a few people have lot engines when using these, apparently they are bored out stock units that have been know to get hot and stick because of the thinner bored out walls

A easy fuel mod is to replace the fuel pressure reg with a after market raising rate one to increase your fuel rail pressures. Once again your looking at a remap. Depends a lot on what you want and where you want to go long term as regards mods and power.

You\'ve not upgraded your fuel system yet ?  What duty cycle are your injectors running ? - you should not go over 80%.

I\'m running 1300 cc secondaries with no issues what so ever while running a full width Apexi GT intercooler.  To manage these I\'ve had to upgrade my fuel pump (Bosch 404 or 044, which ever the intank one is (the other is a secondary inline), and then uprated fuel pump wiring on advice.

I\'d get rid of the walbro to start with. Your better off with the standard pump. Just upgrade the power supply to the pump and the earth to the pump.

What about buying a greddy elbow with the additional injector holders !!! Then you can run 6 injectors and keep the standard 550 850cc\'s in place.
Just a thought and i might know someone thats selling one ..........................whistle whistle:rolleyes: :Laugh :Santa

Do any of the above and make sure you replace the fuel filter, makes a big difference to the flow rate.
