Where can I get a 50 trim Garrett turbo, cheap in the UK?

So, I'm looking for a Garrett T3T4E 50trim with a 76mm turbine (Stage3 wheel) AR .63.
What is the cheapest location for a turbo like this?

CHeers!

 

Does Garrett GT3076R fall into simmilar spec? If so i know a good source

 

Sorry just red your post properly, you said 76mm turbine wheel, that is massive! GT30 wheel is 60mm i thing and GT35 is 68mm? i think anyway

 

Definitely try AMT engines in Chesterfield 01246 273929, I doubt they will be beaten on price.

 

If the GT3076R is cheap enought, I wouldn't mind
But from my understanding, a 76R is 84trim, so I said it wrong in the first place. Sorry

The AMT engines have a web site?

 

They do, but call the chap ( Andy) as he will do better than the quoted figure.

I think I'll give them a ring tomorrow. Let's see if he can understand my English
