Its crazy what they are getting its like a mini 2jz
I think we compare too many engines to the 2jz 😂It basically is a 2JZ at half the size lol
It is a great engine

Considering that the 2JZ was a 3.0L I6 and they could get 1000hp on stock internals, this is coming is at half that hp with the engine being half as big in a 1.6L I3 putting out 500hp. Exactly on par with the legendary 2JZ. Maybe we have the beginning of another historic engine!Its crazy what they are getting its like a mini 2jz
Timing chains are meant to last the life of the engine, you shouldn't have to worry about a chain snapping or needing preventative measures. Working at Subaru, I've only ever seen 1 snapped chain and it was after an engine rebuild. Interference doesn't mean it won't be relilableI thought Toyota would only use non-interference engine for reliability, but oh well it kinda proves the point that reliability isn't the top priority for GR Corolla.

So, would you preventively replace timing chain at some interval or it'll last the lifetime of the engine?
From other interviews i think its been gleaned that the metal in the pistons is improved and improved piston oil squirters.I have seen a couple of videos mention the Corolla GR G16E-GTS has upgraded internals to achieve more power compared to the Yaris GR. However, when Naoyuki Sakamoto is asked how they achieved more power in the Corolla GR he references the exhaust design to reduce back pressure. Are the engine components really upgraded? If so, how?
That’s a nice bonus. The rods and crankshaft are already forged. Improved piston material/components is a welcome addition.From other interviews i think its been gleaned that the metal in the pistons is improved and improved piston oil squirters.
Just watched that this morning. Good video
It’s very much in line with Toyota’s smaller performance engines for sure.It's kind of surprising that they can get this much power out of 1.5L considering its economy engine roots of open deck and cast pistons/rods. Outside of the ball bearing turbo and main bearing girdle this is a very ordinary engine. I'm not saying it won't last or isn't capable, just that it's not overly impressive from a technical level compared to say the B58 engine which is extremely stout.
JZ engines are non-interference. Unless you install a much higher lift cam.2UZ and 2JZ were interference motors 🤷♂️
The JZ with VVTi is an interference, non-VVTi is nonJZ engines are non-interference. Unless you install a much higher lift cam.
GE non-VVTi / GTE non-VVTi = Non-InterferenceThe JZ with VVTi is an interference, non-VVTi is non
