I'm running a single s475 and wanted to see how a .9 exhaust housing lite.. My turbo Is a s475/83/1.10
 
I'm not sure about your setup, but I switched from a 1.0 housing to .90 on the same turbo and it made it a good bit easier to drive on the street. However, it tends to surge more on the top end of the track, so there's a give and take to it. Just my .02
 
I don't really race it! If I do it's always form a roll so keep spinning down I'm just switching form hx35/s475 twins to just a single s475 form the twins it just had a 1.10 and it'll be to laggy for me to drive.. then if I go twins again I got a pt106 with a 1.15 I'm going to throw under it..
 
Thanks for the info by the way I'm just getting in the diesel sene I have always been nitrous man myself..
 
I'll let y'all know how this 475/.9/spool flange works out. I'm thinking I'll need 1.10 but if it doesn't surge bad I'm leaving it alone
