New (Unconfirmed) Details and Specifications of US-Spec MKV Supra:

[lemetier]

I was told by another source completely unrelated to A70s source to expect an iron block and a well flowing head. This was maybe 3-4 days ago. This source is not an engineer but someone close to Tada-San that had been in and driven the car.

The iron block was still pretty unbelievable for me too but with the latest stuff from A70 and now this, I can't help but be a believer.

Maybe poke to see if it’s iron sleeved bores? That would be more in line with the S58 @ 490hp.

it's solid iron, but I believe it's likely composed of CGI. What I don't know is specifically where the block came from; I was told it was an existing design that hinted at the M57, but my latest conversation almost sounded like the motor will still carry a B58 designation (different version number?)

As Guff said, one of Tada's closest friends made a FB post about the block being iron a few days back if anyone was still on the fence. This particular individual is privy to product planning/PR and engineering efforts and generally knows this information before anyone else outside of Tada's inner circle (even myself).

Can you share the link for the non-believers?

So is the Z4 getting the B58 with the aluminum block?

 

[A70TTR]

they were on the fence last I checked, but it seemed like they were leaning more towards the traditional aluminum B58. IMO, it also makes far more sense for them based on their market etc.

Thanks, I also wonder how long until the media gets hold of your post.

 

[A70TTR]

I don't think they care, otherwise they would have posted ages ago about the composites and a ton of other stuff I've given away over time.

granted this one has a bit more confirmation, but they dont seem to care much about confirming facts as seen time and again haha.

Okay, this is a game changer. If this is a bespoke, CGI block, with worked heads and D-4S derivative system... the scalability in tuning will be practically limitless. This seems to be in the vein of a 2J successor that Tada says he was aiming for.

So if the car comes out with mid 300 bhp, the insurance companies can rate me on that, then I visit the speed shop!

CGI FTMFW.

Forgot to add that the M57TU was made of CGI before the all aluminum TU2 came out and that's what I base my analysis on in part.

 

[MA617M]

Awesome. Thanks A70. It wouldn't make sense from a vehicle systems perspective to have two I6s (Iron and Aluminium), so I'm guessing that any I6 would be iron?

Nice to see it flows well too. Anyone that knows the 2JZ knows that the head does flow well at all. Handle a bazillion boost, reliably? Sure. Flow good cfm numbers? Yeahnah

This sounds more like the JLR Ingenium R6 that’s yet to be released.

 

[A70TTR]

That reminds me, it's also possible that the design was 'existing' yet unreleased. Semantics make guessing difficult.

 

[MA617M]

Awesome. I just hope it sounds angry. BMW's I6 of late sound shit, and there is no excuse for that.
