Hey folks. I have a few questions as I am about to embark on my single turbo setup shortly. I am still in the stages of collecting parts at the moment. Right now the setup is stock twins with 440cc injectors, safc-2, with stock turbos at about 12-13 psi full 3 inch exhaust, stock fuel pressure regulator. I didn't have it dyno'd as our only dyno in the country was moved and not reassembled as yet.

The single setup will be Holset HX35y with .71 a/r, safc-2, full 3 inch exhaust, tomei type s fuel pressure regulator. Now I was wondering I was thinking about getting some 800cc side feed injectors. Can I tune them with the safc-2?

Secondly I will be using a Toyota Supra Bosch pump 12v ensured, will it be enough to get fuel to the injectors via the stock fuel lines or would I need to run larger lines or can I even use that pump?


Would I be off sticking with the 440cc injectors for now?

Looking at around 450-500hp with an afr that would not have me leaning out. Eventually I will be going standalone.


Thanks in advance for any help provided.

 

You shouldn't need to be moved to the engine forum having been here since 2009. Please use the proper forum

 

I would look for 550-650cc injectors if I was shooting for 450-500hp

 

Sorry man. I just recently really started posting. I spend time reading the main page. so pardon me while I get use to posting and asking questions.

 

Reason asking about the 800cc injectors is the use of the stock fuel rail for now and also it's high impedence. I can come across the 800cc injectors very easily vs. the 650 SARD high impedence side feed. I really want to eliminate the addition of a resistor box

 

If you really want to run the 800cc I would recommend you invest in something like a emanage ultimate, some would even recommend a full stand alone. I think you likely to do alot better sticking with the 440cc injectors while using a super afc. A wideband would be a good tool to have on your set up as well.
