I have searched, but cannot seem to find the answer. I want to replace the stock rubber hose couplers with silicone ones. The stock ones are old and I believe may have cracks that are opening under boost, causing a leak. What size couplers do I need to get? Same on both ends, or is a reducer needed? I am still running the stock top mount intercooler with the stock turbo, and have no plans of changing it.

Could you not just take them off and measure them?

Not while I am at work. Very Happy I also wanted there to be a record here so anyone searching for this in the future can find it.

That is perfect.  I found a company selling this kit in the US as well, so I should be able to get it a bit quicker.  Hard to tell, but it looks like it might actually replace the hard bits of the piping too.

As Mr b says it only replaces the rubber sections on the standard intercooler and turbo .... don't think I've ever seen hoses that replace hard pipes ...

The order I placed for the Samco kit was rejected because they said they were no longer available.  I measured the circumference of the pipes on the car, and did the math.  Looks to be 2.5" diameter all the way around (as Gostek stated).  The bottom looks to be maybe a 45 degree, and the top is a 90.  I am going to try just ordering some couplers from a company here in the states.  It looks like you can get both for less than $40 US.

You can get the samco ones here in uk.

I am going to have a run at ordering the individual couplers from a US supplier, as it looks to be a good bit less expensive than ordering the Samco kit (and I can get them much quicker).  If they do not fit, or I run into other issues with it, then I will just order the Samco kit from that side of the world.  If it works, then I saved ~$80 US, if not then I am only out about $30.  I will post here if they fit and look to be good quality so others can use them as well.

Ordered from Amazon. Total of $32 for both.  I ordered a 45 degree for the bottom and 90 for the top.  I will have them Sunday, and will go ahead and fit them if the weather is nice.  I'll update the post when done.  My only concern is that the bottom may need to be more like 30 degrees.

I put them on last night. 2.5" works with a 45 degree on the bottom and a 90 up top. You will have to shorten the length on each side, as they are way too long as they come. The ones I got, I picked up from Amazon Prime for $16 each. They seem to be good quality.
