So I'm currently getting ready to drop my 2JZ in my 350z however I'm asking you guys for some advice with this in mind. For the time being I plan on running the stock turbos due to financial reasons. I want to get the car up and running within the next month and I have the parts to do so. Waiting to save up for a single turbo would make down time about another 3 months. So with all that in mind my question is should I run with a radium fuel rail and ID 1050x injectors (which I have) or are the injectors to much at the time being considering it'd probably only make about 300hp. Also what is the point of the "bottom" ports on the fuel rail are they just extra feeds? I would assume I would just need to plug them since I'm running one feed and a return.

 

Why add bigger injectors if you don't need them.

Stock 2j injectors are good up to around 280-300hp being 330cc IIRC. Adding a new rail and injectors is just adding headache to a non existing problem. Not to mention you just put miles and duty cycles on them wearing them out faster.

I say just keep them in the part bucket until you upgrade the turbos. I see almost no gains in going bigger in your situation on stock turbos.

Your stock injectors are 330cc.. So you would be literally tripling the flow size. Which would require a bit of tuning with literally 0 gain.

 

unless your standalone ecu it will be hard to tune a piggyback for 1050s

 

You will need a engine management solution to run anything besides stock injectors. Fuel rail any brand will work.
