What's up H-T? I've got a question for the pro's. I bought a 90% complete turbo kit. It is coming with 780 precision injectors. I have a 98 JDM ITR swapped EJ8 thats bone stock. I'm only wanting to run it at 6-8lbs. It is a daily driver and I drive about 17 miles one way to work. I would also like to know what you prefer to run Fmu & vafc (< since I'm not going to be running over 8lbs), S300, or Neptune rtp. Which is more user friendly? I've done some searching on here and google. I am wanting "up to date" info. more of what I read is for older software. Technology moves fast and things change. So again thats why I'm asking for "up to date" opinions.. Thanks in advance..

 

FMU and VFAC are the pinnacle of stone age technology.

Those will be fine. Your tuner will tell you whats safe PSI to run according to your set up.

youll need a fuel pump and new filter.

You also should get with your tuner to see what he tunes on since re-tunes will be needed. then you know what route to go.

RTP is not needed unless your data logging to which your not, so the basic neptune program will be fine to burn on your chip.

 

OK, I bought a Neptune RTP/Demon today Thanks to ^^ Rob giving me the guys phone number.. He said that the RTP would be a good set up. Plus it was only about $20. more. Thanks for the info. I just wasn't sure about the injectors but if you say there fine then cool.. Thanks again..

 

All this talk about psi.......and you didn't mention what size turbo or even what HP you're going for???

How do we know which injectors will be best with so little info?

 

Bone stock ITR on pump gas is safe to 300-350whp meaning you need between a 550-650cc injector. With Neptune and a good tuner, those 780s should be fine. I would suggest buying a GM 3bar map sensor before you hit the dyno. There's no reason to limit yourself to less than 11psi. It'd be helpful to know more about the setup...specifically some details about the turbo

 

I saw the kit, Its an AFI kit with .57 trim garrett.

Ive been answering questions thru PM's and its all good.

btw hes got a rtp demon coming with software from turbogixxer

 

Pump gas will be 91 octane <---- thats all we have around these parts

Neptune RTP/Demon coming soon <-- stated below

I'm not wanting to crack the stock cylinder walls <----- that's why I say 6-8lbs

T3/T4 Garrett .57 trim <-- stated below

AFI Ramhorn manifold Afi Intercooler w/ 2.5" Powdercoated piping Tial wastegate and tial bov..



Thank ya Bro..

 

well, you tuner will get you the best safe relaible boost setting for your 91 octane. So no worries.

The OEM map will work to 10psi... so if your 91 gets you past that, then look into a 3 bar like stated above.
