    10cm is found on the HX30, which makes it much more rare than the HX35/W's 12cm housing.
    10cm is twin scroll, and I believe it's available in both v-band and key-hole flange type. If it's keyhole flange, you can just get a flange with V-band on it, or weld one to the flanges that the guy in the For Sale section is offering for a great price.

    I think the bigger issue is running out of useable rpm before things start breaking, not so much running out of turbo capacity

    any one know where to get specs on a said holset when i have the numbers off the data plate?

    also, i have an h1c. would it be better to weld a flange to the stock mani or crossover pipe and run a 38mm external wastegate or switch exhaust housings to an hx35 internal wastegate?

    going to be running in stock turbo location.
    thanks,
    Chris

    http://www.turbointernational.com/ If you search the turbo p/n it will give you a list of the components. You can click on most of them which will give you some specs and dimensions.

    That's probably not a real Holset. A lot of knock offs have started showing up lately. Either that or it's some kind of custom deal that company came up with. If you want a "better" Holset, you'd be better off getting a real one, a Bullseye Power exhaust housing and a Batmowheel.

    It is real and pretty much every single turbo dealer in here sells them. Knock off are illegal and customs will take them.

    http://www.myholsetturbo.com/40appnotes.html - maybe this is HX40Super that they sell in here.

    If that is a legit Holset site, then it looks like the Super 40 exists, but I don't see anything there about a Super 35. The fact that that one is shown with the Holset ID and serial tag removed makes me think it's not a genuine Holset product and is just something that site puts together using Holset housings. All I can find about legit upgraded Holsets is info on a Super 40 and a Pro 52.

    It's Customs job to know genuine and counterfeit.
