it would be amazing to see a 100mm tb on the 8v oe intake haha. I suspect its a 60mm tb if it's been punched out, but it didn't really look like it had been when I briefly had it off to install the tps adapter. realistically, anything over about 65 to 70ish mm is probably overkill on anything except the max-ist of max effort builds with power goals in the four digit range. the Q45 in the gold car looks neat, and it's not as big as it appears to be, but there's really not much difference in power output from 80% on up (except that pulling back to 97% turns the nitrous off
)
