Alright bear with me guys, I havent posted here or been on here much so please redirect me if there is already a thread about this subject.

I found some 800cc injectors for the Ralliart. I was curious what else I would need to do to support these injectors? I'm about to buy a turbo back exhaust and start off with the AMS performance stage 0 with the ECU flash and boost pill. Thanks!

 

Definitely upgrade the Intercooler and UICP before anything else dude

 

Injectors are gonna need to be scaled for sure.

 

for bigger injectors... you need a bigger fuel pump and a turbo that's bigger than the EvoX's turbo....

 

+1 on the fuel pump and you need an ECU tune too.

 

800cc injectors was good for 344/322 on a dyno dynamics running a fp red with stock fuel pump.

 

Bigger injectors are not going to be necessary until much further down your modification path. Neither the stock RA turbo, nor a stock X turbo will max out your stock injectors unless you are planning to run e85 fuel.

Unless you already have them, I would recommend investing your money elsewhere, first, as you will not see any gain, whatsoever, from the injectors at this point in time.
