Additonal injectors
Guy's I am doing a single turbo conversion and wondered if the following would be possible or has been tried?
Instead of buying some larger secondary injectors would it be possible to add in a second secondary fuel rail mounted on the UIM for instance and piggy back the wiring of the injectors from the stock secodary injector plugs. Then in my apexi ECU tell it I am running 1700cc secondary injectors?
Anyone? theory sounds good!
Let me know
Thank you
Lee

You really need to search. There are aftermarket LIM's that have additional injector bungs out there as well as other options to add more injectors. However it is much more in depth as far as the tuning is concerned. You cant just add the cc/min's of the injectors and enter that into the comp.
OH, ps the stock fuel system aleady comes with a primary and secondary rail, so you would be adding a third rail...
Most people just use larger primary and secondary injectors with great luck. When I still had the rotary and a single I used 850 primarys and 1300 secondarys and was able to make 370whp within 80% injector duty cycle. Dont really see the need to add more rails when you can get plenty of fuel with just upgrading the stock rails with larger injectors.

Thanks for the reply..
I know all the traidtional routes! I was trying to think of a potentially cheaper/alternative route.. (I can do or get machine work done and have spare stock fuel rails and injectors). I realise this is adding an additonal fuel rail which if you are going for big power would be normal.
Just thinking aloud!
Anymore info anyone?
Cheers

Even if you're going for high HP numbers, you still wouldn't necessarily need a third rail.
