Fuel Pressure Regulators

[highlift]

I am planning on running some management [Greddy Emanage] as welll as installing a ZEX Nitrous system [55shot] B)

Gonna take the plunge for the occasional blue fire spitting hehe, but on a serious note, the ZEX system is designed to run on stock to slightly modded cars with no need to replace the stock fuel pump but I was trying to think on the grand scale of things.

Should i look to install a fuel pressure regulator and possibly a bigger fuel pump to deal with the new demands???

you will have a hard time replacing your FPR, it's in the pump housing in the fuel tank, not on the fuel rail like a conventional return-style system.

Your car already has a FPR... it is located in the pump housing in your fuel tank... The fuel system on the zze rollas is a returnless system meaning there is no return line running to the tank, and all the fuel sent to the rail gets used....

If you wish to run an aftermarket Adustable FPR you will need to modify you current fuel pump housing and remove the std FPR (may aswell upgrade your pump while you are at it I recomend a walbro 255lph GSS342 fits with little modification required and you can get one for $175 delivered to anywhere in AUS from http://www.importbitz.com.au/ ) you will also need to run a return line back to your tank to return the fuel, and you will need to either purchase an aftermarket fuel rail with the ability to run a return system, or tap a fitting into the end of your current rail to run the return from...

IF you do go down this path, then with your emanage i would recomend getting both the optional ignition and injector harnesses, it will give you more flexability in the tuning...

But In reality if all you are planning is to run a 55 shot and posibly clean up the a/f ratio and adjust the timing with the emanage, then there is no real need to upgrade the fuel pump, or change to and adjustable FPR....

For more info on nitrous systems with regards to the 1zz and 2zz's take a look at http://www.newcelica.org/ there are plenty of guys over there who have nitrous systems installed, all with different setups.... so you will be able to get an idea of all the choices you have.... ther is also a guide to setting one up in their installs section...

Hope this helps
