Is anyone else on the fence due to the engine choice?
I'm sorely disappointed that they're not using something like the IS350's 3.5L V6 in this car... never mind that they're (likely?) putting a boxer engine in it.
I like the concept of the car, but the powertrain is pushing me away. |

A boxer 4 cylinder offers some significant advantages in a FR platform. It lowers the center of gravity due to the low height of the motor. And it moves the center of gravity back due to the short length of the motor. Flat fours are also inherently balanced on one plane (as opposed to both like an L6 or H6, but L4s are not naturally balanced at all). And if it is an EJ series motor, they are proven that they can make good power. More than most people will need in the F/T/R-86/S.
It's an excellent choice, despite not being from Toyota. |

what dimman said, H4 is the most naturally balanced engine apart from a V12 or a really well designed I6 due to moment coupling and canceling. I4 suffers from a end-end rock.. in short no i am not on the fence as the engine is one of the reasons i love this car since i cannot afford a 22B, do not like 4door saloons and would not be seen dead in a Porsche. I would love a Baja converted super with a EJ20 - T or a meyers manx/towd but only for bush/bashing, not for street

The only way I want to see anything other than a 4 cyl in this car is if they can squeeze an EJ33 in there without completely destroying the balance Not very likely to happen so most of us are going to pull every last bit of power out of whichever size 4 cyl we get

He may be expert in MR series and/or V6 engine... but sounds like newb on boxer engine to me. Of course, I stand to be correct. I'm no way near PhD or expert of boxer engine either, but stating that cuz of boxer engine chosen over IS350 v6 engine (2GR-FSE iirc) is lame excuse to hating this car.

i hope they develop a new engine that is not an EJ. nothing wrong with the EJ, but i want cylinder heads done by Yamaha.

That would actually be pretty sick, EJ20Y (for Yamaha!). Spins up to 9k or something... |

Subaru have been improving the EJ engine series for 21 yrs, but I do wanna see how how much improvement can be seen with Yamaha tuned EJ heads... at the same time, I'm worry how much tq gonna be lost.
