Thread: Stock injectors or 42.5?

Will stock injectors be enough for an s1x, gen v with a 3.4 on stock heads or should I get 42.5 injectors?

42's fa sho.

i also have a set for sale lol

Whoever has 42's for sale pm me your brand, mileage, and price. Thanks!

There's a classifieds section for that.

honestly you might be okay on stock injectors if you arent trying to quelch knock with fuel.

Yeah stock injectors should be ok, but you know you wont be done modding so go 42.5 or 60s.

Go greentops! I will be gettin inectors for xmas...so sellers be ready then comes 300+ whp finally

Chris..Rule of thumb is that stockers are good on a Gen V until you hit 3.2" pulley size. That's where they typically start to run out of room.

When I initially modded to an S1X/Gen V/N*/3.4" I stayed with stockers to keep costs down.

Bill.. Aside from keeping costs down, would it be beneficial to run the 42's? Or would it be too much fuel? Looking to set myself up for future mods beyond the cam and gen v.

Future setup, go 42.5's.

Here's part of the thing. The larger the injector the less atomization of fuel happens. the spray on stockers is say a fine mist aka most ideal. The spray on something like a 60lb injector is more like a garden hose.

Gotcha.. I just wouldn't want to run pig rich and destroy my motor

I ran out at 3.3....but I agree with these guys on staying stock as long as possible to save money

because youre using fuel to keep knock at bay instead of running lean like youre supposed to.

I'm not running super rich. Just a tad
