Just purchased a new Garrett GT3582R for my TT and want to get the most out of it. I found Kinugawa turbo parts sells the A/R .70 housing and the billet wheel upgrade. I spoke with MTQ in perth and they said they have installed a few and have balanced fine and look half decently made. What are your thoughts on this brand and products? They also sell a Anti Surge housing, what is the benefits of this?
