Is the reason you can't deal with modification to do with $$$ or time or something else? Cause it may be cheaper to get different ones fitted with some mods. UAS have kits that can bolt straight up more or less. http://www.uniqueautosports.com/pricelists/pricelist_300zxturbos.htm Also some aftermarket ones here: http://www.amecautocare.com.au/Turbo list.htm And another option (but might take a while to send your cores and get them done) would be here: http://www.ttzed.com/products/products_listing.cfm?cat=30&grouping=1&title=Turbo Upgrades
You can always get new cores fitted to your existing turbos Try Turbos 2000 phone 0050896000 Shane rebuilt my turbos, one with a new core, very good technician has all the right equipment and well experienced in rebuilding turbos. I paid about $800 for a new core fitted a while back.:zlove:
