would getting some refurbed injectors make any differance to the performance of my car? is there anything that wears inside a injector?

cheers Neil

AFAIK the problem is that over time deposits can build up on the injectors and reduce their efficiency rather than them wearing out.

i had them done in my IS when i had it, waste of £40 imo

Don't buy refurbished ones. Get a set refurbished yourself. If you refurbish an injector and leave it out of the car for any time more than 10 days and it will be no good. Air has moisture in it and any moisture in the injectors will corrode them. Buy an old set in need of refurbishment, get them done, once refurbished swap em over, then sell yours. You WILL notice the difference. Iirc about £10 or £12 each. Cheaper for a 4 pot!!

Had mine refurbished,
Yes they made a difference, much smoother.
I took mine out sent them off to injectortune (who have a link on the trade sales forum here) very quick turn round.
Can definately recommend it.

BG44K £20 from Kwik fit - much cheaper and very effective

You'll never go bust selling snake oil to the gullible!
Reconditioned injectors are probably the single most cost effective improvement you can make to the average E30, assuming the injectors fitted have been there for 60,000 miles or so.

so its good to use then ?

are you saying not brian ?

I think what Brian is trying to say is...................NO!

How can anyone think that putting a liquid through the injectors would be as good or better than replacing the o rings, gauzes and heads and an ultrasonic clean ?

So I could expect a bit of an improvement for ones that have been there for 145k then Brian

As part of a package of making sure everything else is working as intended, then it will, but if for instance, some other fault or deliberate modification is already making the engine run rich, then refurbed injectors will initially make things worse until the other problems are sorted.

It will be Brian - I don't think the engine has seen any non-essential work for quite some time - it hasn't been messed with but then it hasn't been maintained either

No offence Tedswagon, can anyone confirm this?
I was thinking of getting mine done and this is obviously a factor if true. Surely they run some anti-corrosion coating through them when they refurb?

EDIT:- Maybe this is true as a general rule when you don't know for how long and under what conditions they've been stored, but I'm sure if treated and stored properly it's OK.

I purchased some refurbed injectors from a zoner and had them sat in my spare room for nearly 2 months before fitting them. After fitting she fired up on the first turn of the key, all injectors worked as they should and you can feel the difference, the engine feels perky again

I removed my fuel rail, removed my injectors, pushed on a 5cc syringe, pressurised it with carb cleaner, hooked the injector up to 12 volts and blasted the cleaner through each injector - result;
single best fix i have done, slow kangerooing at low speed when cold is gone, ticking from injectors that goes up and down with revs is nearly completely gone and the power delivery is much smoother. It took a couple of hours as it was my first time, but man, what a difference.





Cost me 50p for the syringe and £5 for the carb cleaner.

No offence taken. All I can base this on is what the guy who ultra sonicly cleaned / refurbished mine told me. First thing he did was check the efficiency of mine, spray pattern. On the e 30 it is a bit basic, no pattern, just a single stream. But the more corroded the injectors or damaged the nozzle it makes sense the less effectively they perform. The nozzle is plastic, petrol and heat over time make it more brittle so that will see most damaged or broken. The gauze is the to catch anything bigger than the nozzle so as you can imagine it can become clogged. I don't think they are treated with anything to prevent them corroding as they spend the whole time immersed in petrol.
All I can talk about with any authority is the way my engine performs since I had em done, I noticed smoother acceleration as the main advantage. Take it or leave it.

my spray pattern went from water pistol to fine mist spray pattern - nice.

You may well have improved them, but the worn parts and imbalanced flow will still be there. No substitute for a proper refurb, which is hardly expensive at £10 per injector.
Newly refurbed injectors are known to occasionally stick, but a tap with a spanner should sort them out.
