OK, I've read many posts about fuel injection setup for our cars but I would just know if you think that the setup I'm planning to use could work safely.

My car: 2001 Civic EX (D17A2) manual

Turbo setup: intercooled T3/O4
38mm External Wastegate w 6psi spring
Sequential Blow Off Valve

Nothing is in the car yet, I'm still have to buy some stuff like the e-manage, oil lines to the turbo, charge pipes, etc.

Now, for fuel I'm planning to use:
-RSX Type S injectors
-Walbro fuel pump
-Greddy e-Manage

Is this enough to have my car well tuned to SAFELY run 6-8psi daily?

NO "just search" replies, I've tried and I've not found the exact information requested.

If you think it could not work, please make me a complete suggestion.
I appreciate your comments!!

Thank you!!

Just use Rsx injectors and emanage thats good enough for that psi when you want more get the return fuel system up to 10 probably and then when you get internals you can run even more boost thats when you might need rc 440 or something.

Thanks for your reply

But, I've read that fuel pump might get some damage or stop working if using the RSX-S at 8psi or more??

8psi with rsx injectors your good but if you want more then 8 you will need bigger injectors and maybe a return fuel setup

But even if I want to use more boost (12 psi for example), will the RSX-S injectors still work for that amount of boost if I install the return fuel setup?? Or will I HAVE to use bigger injectors??

depending on how much fuel you are controlling through them with the emanage, the rsx type s injectors usually max out around 10lbs

So this means that even using the return setup, I would need to install injectors like the RC 440........
Why not using the RC-440 without the return setup???

What about the RC-440, e-Manage and Walbro fuel pump without using the return setup??

Sorry about the noob questions, I'm just trying to understand everything needed for my setup.

IMO its always better to overkill than to get buy with the min. I would suggest walbro with return system

But wich injectors?? RSX-S or RC???

But I still have the question if the RC injectors could work well without the return setup if using the Walbro and e-manage??

Or if the Walbro pump would work with the RSX-S injectors without the return setup and without having fuel problems at 8psi? (tuned with the e-manage)

at 8 psi you don't even need the walbro the rsx s are good. 12 pounds your going to need rc injectors and probably a return fuel system would be good no necessary but very useful.

o yeah but besides that higher than 10 will probably not be safe with stock internals

So, the stock fuel pump WILL be able to handle the RSX-S Injectors at up to 8psi of boost without having problems with it if tuned right with the e-manage, right??

Right

Thanks a lot for ur info and patience.

Wait a minute
You don't need a return fuel system?

I thought only a stand alone ECU could handle boost without a return fuel system?

Nop, as far as I know, the E-Manage would handle boost setups without the return system.

Just as an example before i switched over to full return with the walbro in tank pump . I hooked up the modified fuel rail and fuel pressure regualtor. At that time it showed me the pressure that i was running. And on my car as you blurped the throttle the fuel pressure would drop at first then raise back up slowly. This was on an 01 civic with only about 20,000 miles on it at that time. This was the point where i decided that i wouldnt want to risk possible lean conditions with the stock fuel pump. All the steps i did on my turbo was in phases. This enabled me to judge each mod and make sure it was working and accomplishing what i wanted it to do. With the full return system and walbro pump i can now blurp the throttle and get just a flicker from the pressure guage where as before it was dropping a good 5-8psi . What it comes down to its not a matter of what you NEED to boost but what risk you want to take by not doing a complete system. Like i cant imagine not having a wideband guage and boosting. Its not a matter of if something will go wrong its a matter of WHEN something will go wrong and by doing the complete system your lessening the chances of WHEN

So could I get away with a higher flowing walboro pump, and a fuel pressure regulator, and just an emanage to run the thing. Im talking low boost 10-15 psi at the most?

Were you using RSX-S Injectors by that moment?? or just the Walbro on stock injectors?
And what are you using now?

 
Rep Power: 327

Was using just stock injectors, walbro and return system. i didnt install the rsx injectors until AFTER i completed the turbo system and started it to make sure every thing else was working properly

I'm running a t25 with the tsi kit, 11 psi of boost, 255lph walbro but no return fuel system yet, and rsx type-s injectors, greddy emanage....

11.5-12.0 a/f ratio, no detonation.

been running on this setup for 3 months now, daily driver, no problems.

and trust me, i don't baby this thing, so it's had it's fair share of full boost.

Have you retarded your IGNITION TIMING with the e-manage?
