If I recall those things are huge. You might have trouble finding a spot to put it. Can't offer any guidance on whether it is too large capacity or will spool too slowly though.
There were guys back when I did my Ferrari kit that were putting GN 3.8 turbos in their Fieros. I considered it myself because that was one of the swaps of choice at the time. I ended up with a race/street 3.1 and DS1 turbo sys.
Did you ever pursue this? I have a 2.8 with the original Miller Woods Stage II turbo setup (later became the Design 1 System if I'm not mistaken). I also have a 89 TTA ( GN motor for the most part) and a spare T3/T4 original turbo that I replaced with a Precision GT6776e on my TTA. The tiny IHI Turbo America turbo that the kit used on the Fiero spools so quickly that the motor out revs the turbo forcing you to short shift 1-2 & 2-3 at around 3500 to stay in boost during quick acceleration. My thoughts are to go with a bigger turbo to actually slow the spool down some to bring boost inline with the rpm of the engine. Not sure if the space is there or not since I haven't pulled the turbo to see if it will fit. I do know it will require a new 3-bolt flange and new down pipe...not really a big deal though. Just wondering as this is something I may pursue over the winter.
I noticed your Raven's avatar and Baltimore location...I'm up in Carroll Co Eldersburg area.
