I think housings of this size are usually meant for 4 cylinder cars (2.0-2.4L), but it might help the laggy boost issues.

    It seems like a good deal to me. You can get a very nice H1C for 150 dollars or so, then spend 140 on a housing like this and probably have a turbo that spools faster than an HX35. I might take this route, let me know what you think everyone....
    I dont know the conversions off of the top of my head but I will tell you to figure it out and not to go too small. In my opinion a .63 with a stage 3 wheel is the SMALLEST that should be put on a z31 with a larger than stock turbo. That would be for an auto cross application where you need the quick spool up but not a lot of top end.

    Just remember back pressure = heat. Heats is the fastest way to detonation.
