hrm 100+ HP seems rather optimistic for just a TRD SC & intake I'd think more around 70-80HP.
Werty has an 07 DC 4x4 with a 7th injector, 2.7 pulley, X-1, full exhaust, and some work on the trans for better shifting and he is pushing low 13s with 0-60 in 4 sec. Tho I may have forgotten a mod or two. Since the X-1 will not work on 2009 or newer Tacos that would be a huge hit in potential power gains.
I will say Beezlebub the difference with a TRD SC is very noticeable. IMHO the 4.0 is a wussy, anemic V6 but with the SC it's a whole new game. I drove an XRunner with a SC and intake and I loved how the 4.0 responded. It felt as if I went from driving an asthmatic, decrepit truck to an honest to goodness sport truck.
Good luck in finding a local owner to take ya for spin!
P.S. Not to start a SC war but the URD
MKII-E is also a very viable SC option.
