ok so i have a s5na that is s5 turbo swaped, i have a 89 turbo ecu and a whole bunch of injectors, i have the na's, turbo and even a few 720's, the thing is that when i go to start my car with the stock t2 injectors in it, it will not start, kinda pops or starts and revs to 3k right away and then dies, but when i repalced the primary turbo injectors with the na's, it starts right up and runs, what the hell is going on cause i even put in new stock s5 t2 injectors and nothing happens. i have the right voltage going to them as well. me and my buddy cannot figure this one out, so does anybody out there know whats up?

 

any ideas at all?

 

My first thought is that your T2 injectors dont match the impedence required, and the NA's do.

But, if its an s5 motor and ECU and all, they only used HIGH impedence injectors.... so as long as you're sure thats what you have you should be ok.

The T2 injectors might just be bad... have them tested if you like. Or my advice would be to just get some new ones!

 

its all s5 junk, and the t2 injectors are new, well rebuilt but working ones, i got them like 5 days ago, as for the impedence i tested the signal and its getting the required amount so im clueless.
