injectors
 

can i run 800cc injectors on stock ecu for secondaries?

I don't know what size the stock ones are on an FC but if they are a different size then no. All the mapping in the computer is based on the size of the stock injectors. Without a way to change the mapping the car will run like crap and the transition will be all screwy. The car will buck and hiccup all over the place. Not to mention the fuel mixture will be off and you wont be able to do anything about it.

Stock FC turbo fuel injectors are all 4 x 550.
Dropping 800's in the secondaries would raise capacity by about 23%.
I cannot guarantee you that the engine will run efficiently without some kinda fuel controller.

Why are you trying to do this without an S-AFC or equivalent?

You gotta pay to play.
Performance cost money.
You try to get cheap, and it's going to bite you in the ass.

they were on the engine when i bought it. the engine was blown when i bought it so i didnt really know what was in there until i recently pulled it apart. does anyone have any 550cc injectors they would trade for two 800cc rc injecfors?

these are the two kinds of injectors that were there. the ones i think are stock not sure. if someone could verify that with me that would be great. and the rc injectors there 800s i beleive if anyone would trade or buy them that would be great too

How much you tryin to get for those 800cc's and is there anyway you can get them tested to make sure they are still good?

He could always put 12 v on the leads and listen for a click. They may need cleaned, I've cleaned injectors by soaking them in a plastic bag filled with carb cleaner overnight , then installing them in a fuel rail filled with carb cleaner, pressurizing the inlet and blocking the outlet and then applying 12v to the injectors and pulsing them on and off. Worked really well for some injectors that had been sitting and were gummed up and stuck.

They could also be sent off and cleaned.

yes i can test them. make an offer on them.
