Sam, can't you use the spring hose clips for it? Just like the golf fuel lines.
Seriously though, they can't be too tight,.they clamp down just enough to keep the pipe secure......the standard 306 ones might even use that type of clip, can't remember though.

Right here we go. At FCS I had the car rolling roaded again.
RS Tuning (Leeds) RR @ 108hp with just a induction kit (ebay filter)
FCS 2012 RR @ 123hp with GTI6 inlet manifold, service, De-cat and de-centre box.
[/code]
So thats 15 more. The de-centre box pipe was blowing heavily in several places which should have brought it down a bit.
There has been a few remarks about the rollers used at FCS etc but tbh you can always say anything about any RR.

Glad to see some sort of proof that it works (C.A.R take note...).
And I will say, your car was running fine until I....errm I mean someone unplugged one of your injectors. Just proof once again this is a worthwhile mod!

Is there any issue with mpg, especially regarding 1.8s?

Nope. Mine didn't change 1 bit. Well except for more hooning!

Lol the only difference to mpg is the right foot getting addicted to the bwaaaarp. Good RR results though Sam. Good to get this cleared up
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - spawn - 18-06-2012
Very very tempted to do this.
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - Eeyore - 18-06-2012
Yep I had £20 to start with and put in £50 for all of the FCS traveling and track time and i got 350 miles. So withg the amount of hooning that went on that weekend Id say it would have been 400 to a full tank which is what it used to get when i first got it!

If you can find them try and Mikalor fuel clamps, by far the best on the market!!
Not cheap but very good and grip well and even around the hose
As for bolts

I've got a full inlet for sale...
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - Eeyore - 11-07-2012
ok here is some evidence of improvements...
Standard @ RS Tuning in Leeds- 108hp
![[Image: RR.jpg]](http://i1184.photobucket.com/albums/z327/srowell3/RR.jpg)
After GTI Manifold and with decat and no centrebox @ FCS mobile dyno with no fans - 123hp
![[Image: samuelrowellATHTOMAILCOUK.jpg]](http://i1184.photobucket.com/albums/z327/srowell3/samuelrowellATHTOMAILCOUK.jpg)
So thats a 15hp increase and with the exhaust not blowing in several places and with fans i reckon it would make a few more!
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - Niall - 11-07-2012
Can't see the manifold making that much of a difference. Don't trust the dyno at fcs at all!
That said I do think it makes a difference.....just not that much!
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - samass - 11-07-2012
agree with niall. the only way to really see what difference this makes, is to do it on the same day, at the same dyno, with the same fuel, the same airflow, the same operator etc etc. the only variable should be the manifold, otherwise it isnt worth looking at.

Hello guys.
I have a 306 S16. I disassembled the original intake manifold. I mounted the intake manifold of the 306 GTi.
I'm stuck because I do not know how to connect some pipes.
before I post the pictures and then I try to explain my doubts!

Speaking of the intake manifold S16 I understand that:
4 - the tube that sends the oil to the engine.
5 - are the two tubes that control the dual valve timing of the intake manifold.
6 - is a tube that arrives to the control unit to control the depression of the intake manifold.
7 - I do not know what is its function.
8 - I do not know what is its function.
Speaking now of the intake manifold of the 306 GTi:
1 - I do not know! (I think it's a vacuum socket)
2 - is the aspiration for recycling oil vapors! (correct?)
3 - is the aspiration of air to keep the engine at idle.
Now let's talk about what I did not understand.
In the transition from collector to collector S16 GTI there are 2 or 3 small tubes that do not know where to connect.
5 - where do I connect the pipes n. 5 that in the collector S16 commanded the double timing?
6 - The tube n 6 arrives at the control unit. Where do I connect the collector of the GTI?
7 - Where do I connect the pipe n. 7 in the intake manifold of the 306 GTI?
1000 Thanks

I have another question ...
in the intake manifold RFY there is a tube that goes towards the pump of the brake. See the photos below to understand the way the yellow line!
![[Image: fJPG-1.jpg]](http://www.theywhoshallnotbenamed/forum/images/imported/2013/10/fJPG-1.jpg)
passes for "a" and splits into 2 directions!
What is "a"?
a tube goes to the master cylinder!
![[Image: f1JPG-1.jpg]](http://www.theywhoshallnotbenamed/forum/images/imported/2013/10/f1JPG-1.jpg)
a tube goes to "b"!
What is "b"?
![[Image: f3JPG-1.jpg]](http://www.theywhoshallnotbenamed/forum/images/imported/2013/10/f3JPG-1.jpg)
where do I connect this tube into the manifold RFS?

there is another tube that starts from the butterfly valve dell 'FRY.
hydroguide comes near the tank and enters a hole in the fender ...
follow the purple line in the following photos.

what's this pipe? where does it go when it enters the fender?
where do I connect this tube into the manifold RFS?
In the intake manifold RFS there are these connections. 2 and 22.
What do I connect 2?
What do I connect in 22?
![[Image: 100_5053JPG-1.jpg]](http://www.theywhoshallnotbenamed/forum/images/imported/2013/10/100_5053JPG-1.jpg)
the connection of the number 22 is that correct?

RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - devilchris - 19-10-2013
With a little patience and ingenuity I was able to do everything all over. The machine is fine. I only have one doubt.
I have not connected the tube No. 8. I put a plug in the part where you put the engine oil.
is that correct?
RE: How to fit a gti inlet manifold to a 1.816v / 2.016v - Dg95pug306 - 08-06-2014
Hi, need some help, i have bought a gti 6 inlet manifold for my 1.8 16v and i'm trying to figure out where the wire for the grey bottom sensor ( A white mini plastic in the throttle body, air sensor i think), i simply can't find the wire which needs to go on there! And another thing is on the top on the manifold there's a some kind of a broken plastic pipe maybe for the brake servo i think, but how do i get that plastic off, or should it be on the manifold?

Great guide, makes me want to do this to my 1.8, though I'd have to source from the UK as I have no chance of sourcing one here in Australia.
The plastic manifold makes me nervous in a 20 year old car, considering how brittle I'm finding the other engine bay plastics thus far.
