I am fixing to have a semi-stand alone (no ignition) and I was wondering on the practicality of the following:

extra 2ndary fuel rail (s4 or S5) w/ n/a injectors (availability and cost)

drill and weld 2 new bungs on intake

run another stock fuel line to the tank

run n/a pump to power it.

I'll move my 460's to the primary and have 4x 550 on the secondary. I will have all 4 secondaries running on one bank.

and we KNOW the wiring can be done.

does the rest sound do-able?

 

You can get 2x 1600cc injectors for the cost of the additional fuel rail plumbing and time to install it.

 

160cc won't fit in the stock fuel rail, not to mention that a lot more time than I do money. If I can't make a setup like this work, then I just won't go for the power. that simple. But if I can, then why not go for the power?

 

sounds like A LOT of work to me.

but i am a guyt aht did homemade stuff on his car, so i know how ya feel.


go for it and good luck.

 

Take the extra fuel rail you want to instal and drill it out or modify it to fit the bigger injectors.

I'm all about making stuff yourself, I've done everything on my car. But this seems like a headache wating to happen.

K.I.S.S. = Design words to live by.....

 

You can get a greddy sub injector holder for not too much money, it allows you to run 2 additional injectors, and it's specifically for our cars......... Just a thought.....
