Gti-6 Injectors = Bosch Ev1 Type?

[boeseturbo 1]

Hi friends,

 

 

are the GTI-6 injectors like the standard GTI injectors (Bosch EV-1 style) ? Has anybody a picture of these injectors?

 

Cheers

Hi Jan,

 

i´ve got a set of them left and i don´t need them anymore

[DrSarty 100 1 Cars]

OK, can we make a deal? I'll go to my garage and post shortly a picture of my GTI6 inlet, with its injectors fitted which you'll see are different to GTI 8v & Mi16 injectors as they are silver & green.

 

I need to know what the flow-rate is of these injectors from anyone please, and what their technical max BHP limit is. Having looked, they seem to have the Weber 'W' logo on and only two numbers, one which may be a batch number as it's stamped rather than moulded in.

 

Moulded: IW204

Stamped (into the green plastic): 2818/02

 

Pictures:

 

Hope the details and pics help and someone can answer my flowrate/ultimate power questions^^.

there's lots of incorrect information about gti6 injectors on the forum, the truth is here

Mine are black and green

265cc at 3bar, which is about 205bhp at 90% duty. I'm using these on the Trio at 4 bar, which equates to approximately 305cc, good for about 240bhp at 90% duty.

[DrSarty 100 1 Cars]

Thanks Sandy.

 

Out of interest, I'd heard that exceding 80% duty cycle should be avoided, and you're running at 90%! Are there any issues with this as I feel between 200 & 240bhp is what I'll need with my build?

 

And secondly, to do this, will I have to upgrade my standard 1.6GTI fuel pump and/or do anything with the GTI6 fuel pressure regulator currently on my '6' inlet tract?

 

Thanks again in advance

sorry to hijack slightly.

 

what can the S16 injectors flow upto? as there the same as the 1.9 ones iirc?

i know people say that using the '6 injectors on anything other than a '6 will over fuel, but im runnin an S16 with a '6 inlet and was wondering that when i get it remapped (eventually) on the standard ecu, is it worth using the '6 injectors? or will they still continue to over fuel?

[Sandy 191]

It would have to be properly re-mapped willxs. i don't know what injectors are fitted to the s16, but I seem to recall they're the same rate as Mi16/1.9 yellows, which are 214cc @3 bar.

 

Mr Sarty (anticipating your inevitable promotion to consultant); less than 85% duty is advisable on an engine that in run at high duty for extended periods, but on a road car, or a light overpowered car that only sees maximum duty for short periods, it isn't an issue. To reduce the duty cycle you have to trade resolution at part throttle and idle. Many people argue that small duration injector openings with modern ECU's aren't a problem, sure it works/runs etc, but i've found significant improvements in economy and smoothness from using well matched (to the power) injectors. The ultimate extension of this is to use two sets of smaller injectors, staged on duty cycle; which gives you the best of both worlds and probably better mixing too. ( I believe it does improve mixing, but don't have "scientific" proof).

S16 injectors are smaller than Mi16/1.9 8V. They only flow 195cc compared to 214cc for the 1.9L injectors. A good upgrade for an S16 is to fit 1.9L injectors! It richens up the mixtures nicley, giving much better throttle response.

If you like the sound of this and want a set of Mi injectors, I have a set in great condition as sent to me by Rob Thomson. If you add £2.50 to our other pillar badge business to cover postage, you can have them with your badges when they're delivered.

Rich, your gti pump is fine for the job as gti6 pumps run same fuel pressure as a 205 anyway

If you dont part with your spare injectors or have any others let me know, Im in need of some, ideally want a bit larger than the 1.9's though.

[boeseturbo 1]

seems to be standard Bosch EV-1 injector

 

 

do anybody know the gasket-ring diameter of Opel VXR Turbo-Injectors?

[DrSarty 100 1 Cars]

@Richie-Van:

 

If WillXS doesn't want the injectors (Mi ones that is) you can have them, but I did offer him first. Perhaps I'll PM him.

 

Plus, I also have a set of those blue ones pictured ^^^ by boeseturbo if you/anybody wants them. I took them off a Rover 600 of some kind and seem in fine nick.

Hi Rick,

 

could you compare the pictured blue injectors with the standard-GTI injectors? Will they fit into the intake and

into the fuel-bar ?

 

Cheers

Yes they do (well they did on my Mi engine anyway), because I've fitted them before myself. I don't think the GTI fuel rail or injector dimensions are any different either.

 

My head gasket was on its way out however, so I never really got to see how they performed.

 

Do you want them?

Do you know the part number of the blue injectors? i want to find the flowrates. (PS, Its Richie on chris's PC)

Hi Richie-Van (using Chris' PC),

 

here's a photo of the 4off light blue injectors, that look Boschesque and came from a 16v rover in a scrappy.

 

Long number on side is: 0 280 155 885

 

They also have stamped on them (batch no.?): B927 on the electrical connector sprouting off thingy and 966 in line with that on the barrel. The long number above runs along the centreline of the injector's main body.

 

Up for grabs along with a set of (good nick) Mi injectors. Richie - you could have them delievered along with your Gucci new rear pillar badges

 

Rich

[chris 417 mi 36 2 Cars]

no good, they are only 148.2cc/min

I only need the sticker part of the pillar badges , not decided what colour Im doing the pillar badges yet.

[DrSarty 100 1 Cars]

no good, they are only 148.2cc/min

 

That seems a very low flow rate. I swear the Rover engine was a 2.0litre. I didn't think the 600 series ever had anything less than 2.0L 16v, but I've been wrong before. I thought it was a 620si, but never mind, they're going in the bin now if that's their flow rate. It's pants!

[Richie-Van-GTi 74 2 Cars]

thats better, logged into my account now

MI wont be any good for me either, looking for around 240cc/min.

[DrSarty 100 1 Cars]

If you read Sandy309's detailed replies earlier, it seems GTI6 injectors (as I have already) will be fine up to around 240bhp when running up and around 90% duty cycle.

 

When it comes to the dyno, I'll see how it goes and if necessary swap for a set of red tops that I've acquired for £60.

 

And there was someone (in Germany I believe) not needing their '6' set. So perhaps you could get them off him and do as I'm doing?

That's true Rich, but you will need a 4 Bar pressure regulator, as opposed to the standard 3 Bar one

Which 'Red top' ones do you have? And what is the part number on them? Because if they are the same as the ones that I have they should be better for your application, especially if you run them at 3 Bar.

well if that is the case then im pretty sure i have some standard 1.9 8v ones lying around somewhere. will have to dig them up and give them a clean.

 

this also means ive some GTi-6 ones i dont need anymore if anyone is after some.

 

Thanks for all the info, Cheers for the offer rich, but as i said, think ive got some.

 

Cheers, Will

That's a good point SJ but one I can't answer as I haven't received the red-tops yet. I would prefer to run using the std 3bar regulator as you say, meaning no more outlay to muck around with fuel pressure via using the red tops (if they're correct & when I get them).

 

However until they turn up, a 4bar pressure reg should be a really simple swap so I just need to find one suitable and cheap enough (What donor cars please?). I suppose I could've spent the £60 I spent on the red-tops on the pressure regulator, but the red-tops came up from a trustworthy, friendly source and I couldn't resist .

 

I suppose it's swings and roundabouts on this one n'est pas? '6' inj + 4bar versus reds + 3bar. Incidentally josh, why would/might the latter be better?
