I have some turbo injectors sitting here and a n/a 280zx which is begging me for new injectors. Now I know that the turbo injectors shoot more so i figure if I am going to change one I should just change all of them. Does anyone know what will happen if I do this, will motor bog out and flood? Thanks

check the archives. consensus is the car will run way rich.

Try it

I think it would run a little too rich also but you might be able to get it to work and get the best horse power by increasing the timing along with installing the turbo injectors but what do i know i have a turbo.

ReON"T Try it!

Waaaay rich. Your O2 sensor can only compensate about 10%, so you would have to run reall real low fuel pressure. There is NO advantage to bigger injectors on a N/A motor running the stock ECU.
You are better using a Rising-Rate FPR.

Read my whole message Tony

Tony you didn't say anything about advancing the timing.

Doesn't matter ONE bit.

You can put the timing anywhere you want to, the timing is not going to do ONE DARN THING other than increase the stresses on the Con Rod. You would have to advance the timing to light the fuel coming INTO the chamber to have a snowballs' chance in **** of lighting off all that fuel!
No way, no how. Turbo injectors supply WAAAAY too much fuel to be properly combusted. There is not nearly enough air let into the compbustion chamber to properly burn the fuel supplied by a Turbo Injector being driven by a stock N/A ECU's injector pulse! Advance the timing all you want, it won't do a BIT of good, there is TOO much fuel and NOT enough air. Period.
