if i put 270 injectors in my 01 ls with every external bolt on possible what are the chances of a fuel system rich code getting thrown and will it really make a difference from the stock 240's as far as power gains or will it just be a waiste of fuel? Has anyone tried this, does it really make a huge difference?

 

I ran 310's on my almost stock b16. car ran fine with them in, but they would not seat right in the fuel rail, so I wa leaking fuel and had to take them out. Didn't notice much if any between the 310 and the 240's, Mostly because I didn't need them.

 

if you put 270's in you will notice nothing but worse gas mileage.....it is pointless to install them unless you are planning on spraying a little bit of juice or youve done alot of internal work and are flowing lots more air, i personally think they are too small for turbocharged applications......your car runs a little rich at w.o.t with a stock ecu, you put in bigger injectors and keep that stock ecu without at least a piggyback system to take out a little fuel and you will have problems including loss of power from super low a/f ratios.........
