    Is there any advantages using injectors from other cars to fit the S3 8L.

    And what about cleaning them?

    Alternatives to paying the price of brand new oem ones?

    You could get them ultrasonically cleaned if you really wanted...

    Dont think you need bigger ones unless your running a much larger turbo and map to suit.

    Think most companies charge about £15 per injector so you're looking at around £60.

    Oh yeh. You should really do it with new injectors too as they might not be flowing the same rates.
    If you like, you can send them down to me n ill do them for a score.

    The best quick easy injector upgrade is the Bosch injectors from a Vauxhall C20LET engine. Available from Vauxhall parts dept. Not cheap though for brand spankers.

    No point on a standard or Stage 1/2 car though.

    But I'd imagine there would be a better feel and delivery of power, I definitely see the point when upgrading a cars turbo's etc but definitely think to myself that there "should" be a much better feel even on a standard car as all our S3's are starting to get on a bit now days...

    How is it you clean them Alex?

    Could be quite alot of difference depending on how much they are out. I remember testing a set of new bosch injectors and just doing a 5 second idle test they ranged from 35cc to 45cc, which is 420cc p/min and 540cc p/min. So one cylinder will be getting 120cc less fuel a min than another just on idle.

    I use pretty much the same thing as the company that Welly posted. It's an ultrasonic injector cleaner n tester, think they're like £5000 worth of equipment.

    Also forgot to mention the spray pattern, you could have one that is pissing out like a hose (just as an example, unlikely) and another with a nice even spray which will burn alot better.

    A garden hose style injector won't allow the fuel to atomise properly which results in a poor burn.

    That's why I recommend getting injectors cleaned.

    And I second your recommendation.... :thumbsup:

    May be worth slapping some injector cleaner through it first to see, although I am sceptical of what that really does to be honest....
