I have a turbo on my 2.1 from an old subie...although the van has very few miles on it with the mod, due to the original turbo being bad shortly after I installed it. Tried an Audi S6 turbo but it didn't produce the right boost, so back to a new subie IHI unit. I had Boston Bob do big valve heads and a cam with more Exh lift and ration rockers and bobs stronger rods. Modeled it after the Robert Lilley Mods of a few yers ago.. Love the way it runs..feels like a 2.2 subie as far as power goes with the 5 psi boost...some prototype pics on the link at the bottom of my home page. aatransaxle.com Daryl of AA Transaxle (425) 788-4070 aatransaxle.com ----- Original Message ----- From: "Geza Polony" <gezapolony@SBCGLOBAL.NET> To: <vanagon@GERRY.VANAGON.COM> Sent: Wednesday, September 26, 2007 10:10 PM Subject: Re: 1.9 heads on a 2.1 motor?
