Is anyone else on the fence due to the engine choice?

Subaru has AVCS and AVLS, Doubt either will be present though. Toyota is working on the engine heads. They are implementing D4-S (direct injection).

The EZ30 was a complete new design at the time.

Sorry, I should of been more specific when I wrote that. Yes, EZ30 & EG33 are some what different. BUT if you look at all the tech they used on EZ30, which came from EJ. While EG33's tech was from... EJ engine.

EJ22 add 2 more cylinders -> EG33
EJ20 add 2 more cylinders -> EZ30
EJ22 improved w tech -> EJ20 & EJ25

...Do you see the Mary-go-around? Or it was bad metaphor?

Mary-go-round works, at least it worked for me.

And in the scheme of things aren't all engines "archaic"? I'd say it really does come down to the technology advancements versus the engine designs. Engine design has been primarily unchanged for the last century with the significant changes being in materials and the afore-mentioned changes in tech (SOHC vs DOHC, timing chain > timing belt, push rods vs cam shafts etc. etc.).

I definitely don't know the full history of the changes, but the principle and primary design, as to say cylinder lay out and 4 stroke etc, has been standard for... I would have to guess a little over a century. Except for those guys at Mazda and their crazy Wankel.

I like the concept of the car, but the powertrain is pushing me away.

If your in to hp out of the box this car is wrong for you, this car is mirrored over the old AE86 this car will be more on balance & cornering ability not 1/4 mile runs.

Most of the major EJ changes are done to the head(s). Basically what seems to have stayed the same with the EJ will have been its bore spacing and mounting points for engine to chassis and for transmission to engine, and the fact that is some kind of OHC. It has come in displacements ranging from 1.8L (maybe less in Japan or Europe?) to 2.5L, so there is no need for major changes to the bottom end for displacement changes. Fundamentally its a very solid starting point for whatever they want to do to this motor.

AVCS is cam phasing (VVT-i)? And AVLS is profile changing (VTEC)? Which systems are on which current motors?

Either way if it's NA it will at least have AVCS/VVT-i. That is pretty much required for a combination of any form of performance with good emissions.

As for profile changing, Toyota seems to have moved away from VVTL-i, (the Lift part anyways). Why is that? Cost? Or just not having a performance platform to bother putting it in?

iirc current ones are AVCS.

how´s the boxer engine compared to the 3s-ge?

if done right, a modern 2.0L will smoke a 3SGE, even the BEAMS. H4 or I4.

Edit: damn it NESW20

me or tom? haha

[Midship Runabout]

Tom. Where did the 3s come from?
