quick dumb question

[Derk_eliso]

do certain cars take certain injectors or are they just kinda like...universal?

[shakewell]

with a few exceptions, they are specific to the vehicle. there are high performance injectors to replace oem, but even those are usually specific to the vehicle. in other words, you cannot just put corvette injectors into your cavalier (if that's what you were sort of asking)

They are pretty much put any injector you want on your car. The wiring clips will be different, so they would have to be wired up for the correct pigtail. However, they all flow different amounts. If i recall correctly the 2.2L OHV are 18-19lbs high impedance and the 2.4L are 24lbs. However, ford brown tops clip into the stock clips, and they are low impedance just like the 96-98 injectors. They are 370cc or 35lb/hr injectors.

There is a lot of math involved with switching them around, but yes you can pretty much run w.e you want. But your going to need a FMU to control the fuel

Thanks for numbers CRJ. Interesting, twin cam has like 4-5 more psi in there injectors.. Im sure that makes a decent diff when u think about it.

[Derk_eliso]

yeah, okay thanks guys. The reason being, when I get my turbo installed I want to up the injector size...not because it's an almost manitory upgrade to get anything out of the turbo, but because my injectors need replaced. I was thinking like 450cc, but I don't want to like mess anything up, lol. The 370cc ones, was that the ford brown tops? is that their name? Ford Brown Tops?....and where could I buy them? Thanks in advance

You can get the off e-bay. In our shops turbo'd 2.2 we are running injectors from a 3400 V6 engine.

In order to select the correct size injector for your application, you might wish to use one of the following formulas.


In most cases a naturally aspirated engine will have a B.S.F.C of .50. This means that the engine will use .50 lbs. of fuel per hour for each horsepower it produces. Turbocharged engines will want to be at .60 lbs. per hour or higher.


Using these numbers as a guideline, you can select the approximate injector size in the following formula for a four cylinder, naturally aspirated engine at 200 bhp.


Most injectors will max out at 80% duty cycle and this is the accepted industry standard.


B.S.F.C is brake specific fuel consumption - How much fuel you are using per horsepower per hour

Thanks Cody. I think the 3400 ones are 25lb ones.... So the 200hp were you basing that on what my car will be when turbo'd or....? I'm confused where the 200 came from, lol.
