90mm throttle body to use or not to use

[94RCSB]

I got a new in the box cable driven throttle body for free from a friend when he got out of the ls game it is a cheap off brand one. My question is I have a stock truck intake on my 5.3 with a vinci cam and 4.11s with a stall can I port my intake to take advantage of the 90 it is getting hit with a nx 100 shot with a shark nozzle and this winter it will be turboed. Should I use the throttle body or just sell it and use the money for nitrous refills lol thanks guys. My engine is a 2001 lm7 the throttle body is a 78 mm stock isn't it.
