you need a turbo more this size.
http://cgi.ebay.com/ebaymotors/T3-T4-T3T...emZ380073424382 . but with a larger exhaust housing. the bigger housing will help control the spoolup better. that same guy also has a cheap t3 band flange adaptor.
here is another. differance here is no internal wastegate. add a large external WG to control boost and it should do well on the 194.
