Fried Injectors..... Check Out My Photos

[HRthirtyone]

pulled out my injectors/fuel rail today and found a bad surprise

is this even the standard fuel rail? was there meant to be collars installed, and they have been blowing out under boost? can i still use them?

cheers

woah nasty... how was the car running before you pulled them out?? have u checked their resistance??

[HRthirtyone]

by the way they are sard 550cc for rb20 engine.

what are the resistance readings meant to be?

It was running fine tho, until i cracked a piston!

Get them cleaned and flow tested, That will be your best bet to see if they are still ok. New pintel caps and baskets is a deffinate need.

you are running the resistor pack arn't you?

[HRthirtyone]

no resistor pack - i thought you need that when your running GTR injectors cos theyre low impedance. these are high impedance top feed specifically for rb20 replacement, as far as im aware.........

RB20's come with a resistor pack, all RB's do... series II RB25 different setup.

But RB20 you should still be using the little black box

arhh k sorry dude i wasnt 100% sure thats why i asked hehe

even running microtech?

i doubt u need one running microtech, just make sure the tuner has set it up the ecu for the correct impedance.

I think you guys are trying to confuse everyone here.

The rb20 runs high impedence injectors and no ballast resistor which is where cruiseliner is confused.

R31nismod is talking about the ignitor that sits at the back of the engine on top of the coil cover piece.

The microtech doesn't necessarily need the ignitor and it definately doesn't need a ballast resistor.

To answer some of your questions, the resistance shoud be between 12 and 14 ohms, the rail is stock, i don't know what collars you are refering to but the assembly you have is complete as the rail holds the injector firmly in place unlike hosetail injectors or side feeds which do have a collar, and i suspect the pintle cap has melted as a result of your engine dying and combustion has gotten back into the intake. A fuel injection specialist will be able to clean and flow your injectors and replace the pintle caps, orings and insulators and tell you if they are still ok.

I suspect that it wasn't running fine if you cracked a piston Find a new tuner once the new engine goes in......

thanks for clearing that up BHDave!

[Cubes]

It looks as if the pintle cap has melted???

Especially Injector2.jpg

[Jolinator]

umm, there is also supposed to be a rubber grommet between each injector and the rail, mine had these stock and i had them replaced when i had the injectors out and serviced. i can take a pic later if needed

nismoid you sexy beast give yourself an upper cut!
