I know you are in the UK and a Holset dealer nearest you would be the best bet, but those guys know their stuff about Holsets, and may even be able to tell where you to go in the UK.

 

nice i reckon its a good start of finding one ,as ive tryed searching for one in the u.k , and have to say half the time i might as well not have rang ,,(useless) ill email them , now and add the rest of the holset part numbers ,,, topman ,,

 

theturbotrader.com, they have the housing in t3 and t4. i've sold a few of them with hx40s. they are very responsive. just call the guy and speak with him, he's very helpfull. good to deal with.

 

ill give them a email or ring , nice one ,, anyone who has a spare or used houseing ,, let me know cheers
