| i saw the advertisement in classifieds and searched for info not bringing much feedback. looked at z1 site and it says there are modeled on Garretts BB design [ http://www.z1motorsports.com/product_info.php?products_id=2080&osCsid=2d7b96c90733a53de681c2ab3a1e8e63 ] and they are comparable to sp530s. anyone here using them? what kind of spool up do they have compared to 530s? they look pretty interesting. thanks chris
