Mr brother in-law who installs hoists and whatnot, was out at a workshop in croydon a few months back, and he said there was a 2ZZ celica there, completely N/A that was able to rev up to 11+ but changed at 10 cause he couldn't make anymore power after 10. He said the guy had put more than $40,000 into the car, it had a full rollcage, huge brakes etc and was pumping out something like 190-200kws atw NA!!
