You just need to figure out what exactly what you want.
You can get the smaller A/R turbine housings machined to fit larger turbine wheels. There are companies that will custom make any turbo specs you want.
For the street I like to use a large turbine wheel that flows a lot & use a somewhat small A/R on the turbine housing, this allows me to use a tighter torque converter & spools up quickly. Yes, it is somewhat choked up some, but I like the way my Syclone runs, on the verge of 11's w/91 octane 100% stock untouched long block street truck.
Your combo is different, manual trans, but it sounds like you want the boost to come in early, question,, what RPM do you want to see full boost? if you say 3000-3500 RPM you can use a larger A/R on the turbine housing, but I would not go bigger than a .96 or so.
Most any good turbo company can help you w/your needs. You just need to tell them what you are looking for, quick to spool, your OK if full boost is not till 4000 RPM etc..
