Lol, it sounds like you have way to many numbers in that turbo description. Are you sure you know what you have?

I'm thinking what you have is a GT3076R (aka GT30R, aka 3076) with a Tial turbine housing (maybe 3603 is tials part # for that specific housing?). 60mm / 84 trim are the specs for the turbine wheel (or hotside) of a GT3076.

If you do infact have a 3076, thats a great turbo for your car & what I'm running. If the Tial housing doesn't work (fitmant or bad size for your goals (A/R)), you can always swap turbine housings. Forced Performance has a great bolt on DSM housing (works great with their cast DSM mani), that would be a great match. This is what I run on my car.
