I have a s475/83/.90 and was wondering if I stepped up to a 1.0 exhaust housing would I see much gain in top end power? Just would like to know if it would be worth doing. Thanks
 
what's the stall of the converter? I personally like the 87/81 turbine wheel the best w/ a 1.0 T4 housing.
 
Its a 2300ish stall. I can build 18psi on the line with the 83/74 .90. I would love to have a 87/1.0 turbo but kindof worried it might be a little laggy
 
I played with both a .90 and 1.0 housing when I ran a 475/83. Wasn't a huge difference in spool up on the street, but the 1.0 helped drop drive pressure a bit on the track. I've run 4 different chargers lately, all with the 87/81 turbine wheel, and it's amazing how quick it'll spool compared to the 83. You can also lighten or clip it to help spool even faster. What I like the best is drive pressure rarely if ever exceeds boost. You've got more fuel than I do and EFI Live, if I can DD the 87 wheel I know you can.
