Toyota has been experimenting with direct injection for over 20 years, the initial D4 system was sold in the Japanese market in 1998. The system on the 86, D4-S was first introduced in 2005 on the Lexus 2GR-FSE motor, this system has been in production and on the road for over 10 years now.
I bet those pumps chirp too, if they're any different from the ones installed in an 86. They typically bury the HPFP in sound insulation, but that's weight, and this is a cheap sports car.

That's not true. (note; some of these engines may have been screwed up by dealership oil fills and owners not taking the responsibility for checking oil levels, I place blame on 'yota for that one).

And 13x in this thread, didn't go through to verify if they were 100% factory fault or not:

And I got bored of searching after that.
We may disagree on the definition of "raced hard", imo this engine should be able to take a beating. When a company advertises it's car for track use, hires professional drivers for promotion and sponsors race teams to use the car I expect the stock powertrain configuration to hold up to autocross and HPDE use within reason.
