Unfortunately, the shape of modern multicam engines does not make this as practical. Back in the days of pushrod or single overhead cam engines, the head and valvetrain were fairly narrow and typically dome shaped. So as soon as you started to tilt the engine it's "height" would start to reduce. With today's dual cam setups, variable valve timing etc. the top of the valvetrain is substantially wider and flatter. As a result (geometrically), when you start to tilt the engine it actually gets "taller" before reaching a certain angle, at which point it would start to reduce again. Now I haven't modelled the 3 pot and rolled it over in CAD to see what the break even angle would be, but I would imagine it would be fairly substantial (30 or more degrees). To actually reduce overall height you might need 40 or more degrees... and at that point the engine is getting very wide AND the intake or exhaust (depending on which way you tilt) is going to start getting really close the hood thus impeding air or exhaust gas flow. Plus at those angles you're starting to upset weight balance side to side, because the point of rotation is going to be about the transmission.
Although the G16E-GTS may fit under the hood in a motorsport application, I highly doubt it would in a road car even with a dry sump. The pedestrian crash requirements are just too stringent. I believe Toyota's choice to go with a flat engine had far more to do with keeping the hood line low than it did with COG (just my opinion). If Toyota were to move to any inline engine, I would bet good money the hood would need to be raised substantially to accommodate it... which is what you can clearly see in the Supra (just look at that Car and Driver COG article to see how much taller the Supra's hood is). Now I'm sure many would be fine with that, but there are also many of us who like the low hoodline/beltline and large greenhouse look, as opposed to the bulbous front end and squinty greenhouse of the Supra. All of a sudden it's not a minor change to add another engine choice, but rather a major change to the entire profile of the car to accomodate it. Brandon

Obviously it's the internet but I made that comment tongue-in-cheek...

Definitely went over my head, but I learned something in the process!

If you want to see what a slant 4 DOHC 16 valve engine looks like, look up the Lotus 904. It sits at 45deg, which was partially to allow development of a 90deg 8 cylinder... which they eventually did. It becomes quickly apparent that the G16 would need major modifications to reduce it's height. Brandon |

taller/longer/larger engines: Honda K-series (I4) - notable example: KPower offers a kit 2JZ (I6) - notable examples: Greddy (also, Collins offers a swap kit) LS (V8) - notable example: Too many, just google it G16E-GTS (I3) - notable example: Toyota Will it fit? Yes. Will it fit under the stock hood? also yes. The following questions get the default "I don't know" response: Is it something that Toyota or the 'GR' division wants to do? Can it be done in a way that it's accepted by governing safety bodies globally? Can it be done in a way that is profitable for Toyota? Will it be done? The G16E-GTS has only been available in the US for a hot minute and only in one really hard to get & low volume model; it won't take long after GRC's start getting totaled that a G16 will get stuffed into a BRZ/86 (or Miata for that matter). |

At the very least, there will be no Toyota engine in the twins chassis this generation

I'm probably one of the biggest proponents of G16'ing the twins there is, ha. I did some rough measurements of both and yes I'm sure you could get it in there but totally wasn't thinking about the ped impact stuff. I guess a hood bulge could get you there. There isn't much space between the engine and hood on the Corolla, but the hood has more of an air gap built into it and sits super high visually. About 6" higher than the 86. Getting hit by a Circuit Edition would be like jumping into a bean bag I imagine. As of today I'd never undertake a project of that scale so I'd only ever concern myself with a factory version. It's hard to see that ever actually happening, especially considering regulation and electrification goals. Quote:

Speak of the devil. More blathem about the hybrid 3rd gen. But sounding more and more plausible, I guess.

2024 BRZ pricing announced. About what was expected...

I think it's a great car and plenty fast for what it is. Keeps up with the VA STI and is faster than the WRX. Plus it's an absolute riot in the twisties. If you want that dream 40k dollar car, maybe a used BMW is more your speed. I want a 15k dollar electric commuter that's as fast as a Model 3. Let's compare notes when our dreams finally come true. |

People only seem to care about numbers, because it gives them a false illusion of going in a straight line real fast. That's why they keep asking for a turbo version of this car, when the weight addition would throw the balance completely off. Keep the car as is as let those who know, enjoy it for what it is. |

It's a fun chassis, seating position is great, getting in feels almost like putting on an article of clothing rather than just getting into a car; similar to a Miata in that sense, but different because it's a coupe not a convertible. I was tempted to pick up a used 1st gen & swap in something better, but they aren't cheap enough for me to consider that yet, if they are, the interiors are destroyed; anything that is already swapped has a cage and/or the rear seats are deleted, AC removed, interior is gutted, etc.; I don't want a track car I want a fun street car. I feel similarly about the Miata; fun chassis, not enough power to make it interesting. Admittedly I haven't driven an ND2, but I'm looking for 2+2 anyways, so not really a point to it. No I haven't driven a 2nd gen BRZ/86, they aren't exactly sitting on dealer lots available to test drive though. I don't need an insane amount of power, I've found that around ~1hp:10lbs is a fun street ratio; the mustang & camaro do better than that, but they also weigh 4,000lbs. |

I want a lightweight 2+2 6mt FR/FMR drivers car with at least 1hp for every 10lbs of car.
Supra doesn't have enough seats and weighs 3,400lbs (3.0 w/6mt). Related: Z doesn't have enough seats and weighs 3,600lbs (3.0 w/6mt). The BRZ & 86 don't have enough going on under the hood & have an engine with known oiling issues, as well as the engine assembly issues. All other 6mt 4-seat RWD performance cars on the market are north of 3,800lbs (M2, M3, CT4V-BW, Mustang & Camaro). Like I said previously, I want a BRZ/86 with a good engine; that's easier than trying to cut 800-1000lbs out of the other 4-seat stuff on the market. |

Probably the best sports car for the money on the market today.

1st BRZ was great, but definitely needed to be wrung out above the torque dip. Apparently the 2nd gen delivers on all fronts, so I'm not sure what the problem is? I do think it's overpriced, but when everything else is also overpriced then I guess it's on par.

There's reasons the Camaro weighs as much as it does. There's reasons the Supra costs as much as it does. No **** you want a sub 3000lb car with 300hp for $40k. Not only that but 2+2? Haha. What a joke. Who doesn't want that? Every enthusiast who isn't looking at supercars would be buying one. But welcome to reality. Buy a used car and modify it or make some concessions. |
