just trying to remain optimistic in a negative situation. That’s all... lolI feel like you were thinking about Tesla while writing "Toyota".

There absolutely is a new one and an old one. The original b58 was used in the LCI BMW 340 and 440. Then there was the update for the Supra and new 3 series. Now there is another update. There will continue to be newer versions of the b58. Old engines are getting phased out.That is incorrect and misleading speculation. Both engines were developed at the same time by BMW and were part of the TÜ1 update. There is no old one and new one. They are just used in different applications. For example the 840i uses a similar engine and is newer than the Z4 M40i.
Furthermore, the "new" engine does not seem to meet Europe emission standards, so phasing out the "old" engine seems even more far fetched.
2020 Supra's B58c is similar to B58M1, telltale signs are the internal exhaust manifold and hp rating. 2021 Supra's B58d is similar to the B58O1, telltale sign is hp rating, compression ratio and the fact it is in the Z4 M40i. As previously mentioned both of these were part of the same TÜ1 update.There absolutely is a new one and an old one. The original b58 was used in the LCI BMW 340 and 440.

Just to be more precise, B58C _is_ B58B30M1, and B58D is B58B30O1. Each engine model has two designations used in different situations. The single letter is what you see when you do a VIN lookup, the long name is the official name of the engine model. The M240i/340i/440i's B58B30M0 is "B58M" in VIN lookup. And the last digit of the proper engine identification denotes the TÜ level, so both Supra engines are TÜ1.2020 Supra's B58c is similar to B58M1, telltale signs are the internal exhaust manifold and hp rating. 2021 Supra's B58d is similar to the B58O1, telltale sign is hp rating, compression ratio and the fact it is in the Z4 M40i.

The B58M0 you refer to for the LCI 340i is the engine prior to the TÜ1 update and not in either version of the Supra.

ya the point is they are phasing older b58s out...2020 Supra's B58c is similar to B58M1, telltale signs are the internal exhaust manifold and hp rating. 2021 Supra's B58d is similar to the B58O1, telltale sign is hp rating, compression ratio and the fact it is in the Z4 M40i.

So as long as "an unfortunate event" causes critical damage to the engine while under warranty - the newer replacement is guaranteed?ya the point is they are phasing older b58s out...
If Toyota provide OTA ECU update to give MY2020 more horse power just like Tesla does, it would be damn awesome.I feel like you were thinking about Tesla while writing "Toyota".
It isnt just a tune. New engine, new pistons and a list of other hardware change.Its just a tune update that makes the power no? Whats the big deal! Mod for mod they will run the same... did I miss something?
yes I know about the revised head, pistons alone wont make power...where does the actually power increase come from? The tune right? If so this isnt a big deal...It isnt just a tune. New engine, new pistons and a list of other hardware change.
I think most of the power increase comes from lower heat at the turbo and better flow through the individual runners as opposed to the single turbo mount on the B58C. Obviously the pistons play a part, etc. but ultimately it's just that it can handle a bit more boost while remaining as reliable as it's predecessor. At least that's my take from the tech details posted earlier. So technically no, mod for mod the newer engine will likely be slightly better all the way up.yes I know about the revised head, pistons alone wont make power...where does the actually power increase come from?

Only the suspension stuff irks me, people now calling the 2020 a good daily. Lmao
mod for mods they will run the same unless I missing something
No... I think you may have lost track of the conversation. My point is no phasing out is occurring because B58c and B58d are developed simultaneously from the TÜ1 update. Neither is old or new relative to each other. Both are successors to the B58M0.ya the point is they are phasing older b58s out...
