Injectors

[WogBoyz]

i did a search cudnt find anything to help me

now my question is

can the manga v6 equivilent model injectors fit into my vs 3.8 v6?

would it chew fuel? and any preformance gain from it?

thanks everyone

NFI on all of them

no point putting bigger injectors in unless you have the mods to support them, and yes it will use more fuel

[S2_VR_]

yeah thers no point unless your motor NEEDS more fuel put into it.... get yours reco'd or buy some reco ones if they are shot...

bigger injectors? hmm noting was said about them being bigger.

Ive heard great things from doing this, they have a better spray pattern that gives it a bit more torque without losing power. I know that they just screw in, same wiring cause its all Bosch gear. Apparently a big let down with the Ecotec are the injectors and these are supposed to make them jump.

If ur that far in doubt go to a wreckers and pull out a V6 magna injector and pull out a VS injector and have a look. You will find that they are the same size. Bosch make different spray patterns for different customers (ie Ford, Mitsubishi and Holden) to the specs that they want, IE economy or power.

Also its not about how much fuel is being pumped into the motor, its how the fuel is sprayed and mixed. Like the VW Golf, uses less fuel and gets more power cause they spent millions getting the injectors to spray the fuel that lets the engine use as much of the fuel as possible. those VW injectors cost nearly $700 each.

You can't tell what the flow rate of an injector is just by looking at them. Many of the Bosch injectors are the same size, but have different flow rates. From what I can tell the flows rates are: 227 cm^3/min(Magna - 0 280 155 723) vs. 208 cm^3/min(VS - 0 280 150 973) .

The design of the manga injectors is much closer to the VT (0 260 155 777 - which are EV 6 style injectors) than the VS ones (EV 1 style injectors). Yes they do atomise the fuel better, but you will be pouring fuel out your exhaust until the car enters closed loop mode, at which point the oxygen sensors will force the injectors to inject less fuel. So you might see slightly better performance due to a better spray pattern, but not because they are larger volume injectors.

The VT injectors are a much better match to the VS injectors in terms of flow rate with better atomisation - however their fuel flow rate is slightly lower than the VS injectors at the VS fuel pressure.

I don't know why the VS injectors are bagged so much, I can guarantee they do a far better job than the VR injectors. Much better designed pintle, and a better spray pattern. That said, when the VS was released the newer EV6 style injectors were available, but they went with the EV1 style - still the VS injectors are not too bad and they are more serviceable than the EV6 style injectors

so bascially adding the magna or vt injectors wont really do much at all apart from making it run richer

[aceventura]

The magna injectors will make it run richer, but I don't think the vt ones will - I am not sure what the consequence of using them would be, but I would it would be small either way. Some companies sell the vt style injectors for VN-VX, so they must be a reasonable match.

The way I see it, the ECU assumes the car has a given injector in it, if you change to an injector that has a higher flow rate without telling the ecu (i..e. by changing the tune), it will just go on as if nothing has happened and inject way too much fuel, so that your air/fuel ratio is all wrong.

yeah i was thinking that too, i mite just leave the vs ones in as they work good and when they made the vs they woulda made the pump to suit injectors and all the rest, i dont wanna stuff around with all that lol

thanks for the info mate

[squidgymop1]

i also on a vs commo with an ecotec in it dead stock except 2.5" cat back with no resinator, anyways if i used the magna injectors, an adjustable fuel reg and have the ecu remapped to suit would i have to improve air flow like bigger throttle body, cai and i high flow air filter to gain any real performace gain and what other mods would i need to do to run around 14 flat on the quarter? i have a mate who has spent quite a lot on his ecotec and only runs 14.2 so iwanna rub it in lol.

engine has done approx 250 thou and still quite a quick car compared to other dead stock vs commodore also take vns with minimal mods quite easily

[daron]

if your getting a remap changing ya injectors is a waste of time your factor ones will be fine for a remap
i have 3 sets magna jectors and tryed them dont waste ya time or cash on stock motor youll just use more fuel if you wanna get flat 14 add boost

[squidgymop1]

not going to turbo or charger. girlfriend drives the car everyday and she has a heavier foot than me

[immortality]

i jsut fitted some reco'd standard bosch injectors inthe missus VS, starts first crank now, much better throttle response and better economy and power

though the difference between EV1 and EV6 was theplug style?

where did you get them man?
