Hi can anyone let me now if i can put 16v injectors in to my 8v 20l gti i have been told that thay will fit and give me better performance any info would be great thanks ja.
-
It's new to me. :huh:
-
wont make proper power gains, if it has any effect it will be purely overfueling which isnt a good thing, if it were that simple more ppl would be doing it
-
Thanks over fueling bad will have to look in to getting more power some other way ..
-
the injectors will fit (but so would cosworth one's!) but you can't beat the ecu (and all the sensor's that give the signals)
If you want more power it depends how much you want to spend! For true power you need supercharger's etc
-
All you will do is dump more fuel in and in the end damage something.

Will they even fit?
8v are traditional back feed type, where 16v are stubby side feed type....so I'm not sure they'll even fit.

I'm waiting for danny_p to get back to me on telling me what saab injectors I need, he thinks it was the 9000 turbo. They are bosch green injectors and are a straight swap over from the current 8v ones. However I now I'm underfuelling very badly (17:1) so I would beneft from larger injectors, but I've got mods to suit the bigger injectors, you don't so if you start dumping more fuel in you will just end up with bad fuel economy, no power gains, more backfiring and possible terminal damage to the engine. Unless you NEED to get bigger injectors then I'd leave them well alone.

I don't think you need bigger injectors, standard injectors will be fine, fueling can and will be sorted with a remap.
-
+1 the standard injector should be fine for the amount of fuel youll need, they will just have to be open for longer/ saab injectors will output more in a shorter time, its all down to the mapping :wink:

To be honest mate, you need to find out why your engine is underfuelling so badly.
Just fitting bigger injectors might mask the problem, but it won't cure it.

I know why it's underfuelling.
There's a 285 cam requesting more fuel but the injectors can't provide it. I'm combining the injectors with emerald management and an ABF throttle body, that's why I need the saab injectors :wink:

Sorry but your standard injectors should be able to cope with the cam, I would find out if maybe they are faulty or not working as they should first, have seen many cars built with 285 or hotter cams but never known someone need to change injectors.
Also worth remembering the injectors will only delivery a preset amount of fuel on the standard map, if you had the car remaped then you might not have an issue.

car was running perfectly healthy when standard. I have the A:F ratios from JKM's RR back in march. Only since the cam it has been underfuelling.
The ECU lets out max amount of fuel from injectors for a preset time according to danny, so sticking bigger injectors in is a ghetto way of giving it more fuel without a remap (although I'm going for emerald ecu as well) as the ECU opens the injectors for a preset amount of time rather than quantity of fuel.

A remap can and will sort that without the expense of the emerald ecu.

I know it will, but I'm getting the emerald ecu for free/peanuts + it will allow me to tune it with far more accuracy and better outcome overall.

I'm surprised at that. The standard ECU map should be able to cope with your cam, although a remap would certainly be better.

You shouldn't need bigger injectors with Stand Alone Management.
What type of injectors are the Saab 9000 type?
If they are the old pintle type - like the old cossie ones...don't bother.
You can do better fitting modern injectors.
Old technology can give poor atomisation at idle, and poor emissions on large injectors...going to modern disc type will give better combustion, lower emissions and if you use 1.8T EV6 types, cheap at breakers.
A set of 150 1.8T will give enough flow for 200+ BHP...180 ones around 240 BHP and 210/225 around 280 BHP, all @ 3 bar FP.
Personally, I'd look for a set of recent 150 1.8T injectors - they are also high impedance and so perfectly suited to the Emerald ECU!
You should be able to source 150 1.8T injectors easily...as people fit 180/210/225 when they fit a K04 turbo...so there should be a good supply about.

there arent any other emerald ecus goin cheap?
