Are there any turbo builders in the UK that will build a one off turbo i.e. mixing and matching components on a garrett CHRA so it remains bolt on but you can use more advanced turbine and compressor wheels?

Why bother when there are so many turbo options off the shelf ?

Although pretty much any turbo specialist should be able to do what you want ?

Exactly what do you have, and are trying to achieve ?

Needs to work within a T03/T04e frame and the replica KKK turbine housing. It is already a hybrid of sorts but the turbine wheel is too restrictive. I want to machine the turbine housing and fit a stage 5 (t350) wheel or similar but most people are only interested in selling off the shelf kit that I have come across so you are limited by the compressor & turbine pairings. For example the t350 wheel seems to come paired with the 61mm compressor wheel which is the well known Garrett Stage V turbo but I would like to run it with a smaller comp wheel. Holset have some nice stuff but I wold have to play around with it quite a bit to make it all bolt up. Current turbo is a T03/T04e 60 trim compressor with a t31 (Stage 3) turbine wheel. I think the turbine wheel is holding back the top end.
