They are designed around a specific turbo and target so you would really need to speak to alyn
Not so. Mine ran perfectly well on a TD05 20g, MD321t and SC46. I only changed the 2 bolt Harvey up pipe when the matching Harvey ported manifold cracked and I went to a 3 bolt GT spec gen 2 manifold and up pipe.
I already have GT spec headers purchased from Abbas on here, I don't want the matching up pipe though.
I have to say I was unaware the uppipes were matched to the turbo

I can most certainly confirm that a Harvey up pipe for a td05 will be visibly different to a 321t so defo speak with alyn.

I had many conversations over the years with Harvey (as many of us did, he gave very freely of his time and knowledge) and in particular about his 'trick' up pipe. One of its obvious advantages is the slip jointing that allows expansion of the manifold without stressing it. However, although he was well aware that I was going from one of his TD05 turbos to an MD321t there was no mention of any need to change the up pipe to match the bigger turbo. And when I changed to an SC46 the same up pipe did the job perfectly well.
I would be very interested to hear what Alyn has to say on the subject as I have never heard there is a difference depending on the turbo.
