Looking for some advice re: fuel system upgrades
 

Hey guys, looking for some guidance or reading materials regarding upgrading my fuel system. I'm running a c38 supercharger on a 2015 brz - stock motor with a lw pulley, red intake manifold, 4-2-1 EL headers and a 3" exhaust.



I'm planning to replace my injectors and fuel pump with the ID1050x and DW300C but was wondering if there is any benefit to replacing the stock fuel rails with something like what radium engineering makes.


Do I need to go ahead and replace my spark plugs too? I've read that using different injectors requires the spark plugs to be threaded deeper or something

I don't know anything about spark plugs but I don't see replacing the rails doing anything for you

How much power are you making? As far as spark plugs, I would keep the OEM ones unless your tuner tells you otherwise. I know a lot of people who run the stock plugs that are boosted. A good investment for your fuel system is the verus fuel starvation door and upgrading your fuel pump. I would only upgrade the fuel rails if I knew it was restricting me.

Replacing the rails is useful if you're changing to a return style loop or adding extras. For stock setup there's no gain
