s400 turbo spec question

[chevy_man]

ok guys ive got a question, I may just be completely stupid and missing something. But I have a e.d built billet s472, and was told it was 72/96/1.10 but I recently pulled the exhaust housing off just to inspect it and make sure all was good. I put a pair of calipers on the exhaust wheel and it says its a 75x84mm exhaust wheel? And ive never heard of a exhaust wheel of that size. Is this a normal size? Or am I stupid or what? Thanks

That would be the smallest wheel I know of for an s400. Commonly called the 83x74 wheel

Ok, I didn't think it could be the 96 wheel because how fast it spooled. but didn't know of any wheels with those specs and wanted to know for sure before I sell it so some one gets what I tell them their getting. I appreciate it
