You can do it without removing the inlet manifold. But you have to be prepared to snap off one of the little pipe that heads off under the intercooler from near the turbo. The new (Samco I assume?) pipe will eventually fit through without snapping pipes as it's a little more flexible.
Whilst it can be done, it's very awkward, involves a lot of twisting, pushing, squashing etc to get the pipes through. After about 3 hours finally getting it all finished with some very grazed knuckles, I did begin to wonder if I should have taken the inlet manifold off . . .

Sorry, reading that I could give more of a clue - remove intercooler, diconnect all the add on pipes, including various jubilee clips (many of which could be a b8gger to get to, depending on where they're rotated to). The pipe will then come out towards the front of the engine bay, snapping the one joint as mentioned in my previous post. It will need a lot of twisting every inch or two it moves. I think the main twist is a little under 90º clockwise (looking from the front of the car), but it really is a case of just keep twisting, pulling, twisting, pulling etc until it comes out. Try and remember the shapes, grease the sticky outy bits (technical term!)of the new pipe, squash it a bit and it will go back through.

Hades is dead right in my one-off experience.
It is a very frustrating task indeed.
Lifting the manifold rather than removing it helps a lot but there is just so much connected that the space gained is 20mm max.
Mind you, that is better than the zero clearance you have to start with.
Get the Samco warm to make it more pliable as the stock one is hard plastic but the samco is silicon that drags against everything it touches!
Good luck.
I prefere doing my gearbox this weekend rather than that.

the main one is incleased/smoother airflow as the samco variety is slightly larger (for standard size) alternatively, if you get a bigger one, like me they compare like this....
This is a special "big bore" 3" version though, but you can quite clearly see the difference in size.

Thanks for that comparison
But in turn, what would the increased airflow actually mean in real terms?
Are we talking more boost or something?
I was sort of advised to get one at some point you see when i had my last lot of work done and never really asked at the time.

potential for more airflow coming in....if more air is coming in then i guess the more potential boost you could make and the more power....
for my pursposes i was advised that potentially the inlet tract was proving to be a little restrictive in that my car would only make 1.55 bar absolute max (hybrid GT30), so i am going to use this, along with a 3" reprofiled cover to see if we can up that a little.

Have heard that the Samco hose can collapse, so I am looking into the APS solid pipe intake kit so far have only seen for sale in the US. APS say they are unsure if there is any difference can't see it myself so after January will take the plunge and get one and their fuel distribution kit.

Well I'm only replacing mine because the old one's split. So all in all, better to remove the inlet manifold then? Sounds like fun. Is one way quicker than the other (i.e. inlet manifold off or on)?

Hmm, still no definitive answer as to why use one really? I know the classic pipe is very restrictive from Andy F's articles within Scooby magazine so i can see why you would change that pipe. But for the bug and blob i really need to know what benefits would become from fitting one of these.
I don't see what it would do.
And don't just say improve airflow i mean, i can say to that, and so what?
Yeah it improves airflow, but so? LOL.
Any more answers on what it actually means in performance terms or are we just talking from a "collapsed pipe" point of view?

Benefits - I found it let the turbo spool perhaps 100rpm earlier, and held on to the power a touch more at the top end. Huge increase? No. Noticable, and pleasant for not silly money? Yes, just.

Well I just got my Hong Kong special off ebay and what can I say - it's not the best most shiney silicone but who cares for £65 delivered in under a week?
So I'm contemplating removing the inlet manifold for this job, from what I can work out it goes like this:
1. Release fuel pressure
2. Remove intercooler, airbox, MAF and pipe
3. Disconnect accelerator cable
4. Move power steering gubbins out of the way
5. Remove plug leads
6. Disconnect throttle body/idle valve electrics and water
7. Disconnect any other electrics or sensors around manifold e.g. knock/crankshaft etc.
8. Disconnect fuel pipes.
9. Unbolt manifold
If that's all there is to it, I'll give it a go. Will I need new manifold gaskets afterwards?

If it's one of the ebay ones, chances are the walls will collapse under full boost. This happened with the "Autobahn 88" one I purchased.
When fitting, put a couple of jubilee clips around the pipe, one in the middle if you can and one on the corner at the front where it bends to meet the airbox pipe. This seems to have cured the problem for me.

i have the 3 inch inlet
be prepared it is a bitch to fit
if you look in the pic you can see how the manifold pushes againes the inlet restricting some flow, if i was doing again i would be looking at some manifold insulaters to try and give a little more space
hows the car going ?
and did i say its a bitch to fit!!!

Ive got spacers going on at the same time, im going to lift the manifold off and do it all at the same time, hopefully with some nice perrin fuel rails too.
car hasnt moved in 3 weeks, due to not having any brakes on the front....being rectified on saturday when i fit my new wilwood 6 pots.
thankfully my pipe is the one without all the pokey out holes bar the DV reentry pipe. so hoepfully it wont be too bad, certainly better than that rubber piece fo crap thats on there at the moment!!
just got to get the cover reprofiled first!

Andy, the reason im changing mine is to suppose the 3" inlet on the turbo, as we found that the car simply wouldnt make anymore than 1.55bar we figured this could be something to try and the current cover is standard size.
It seems to be an awfully large compression for a standard size inlet so we hypothesised that it may benefit from a 3" inlet.....would that make sense to you?
i know that this turbo is capable of more boost as i believe you yourself have mapped one to around 1.75-1.8 (albeit on a 2.33 as aposed to 2.5). Hopefully this will help get a little more air in there anyway.
