Re: Engines: Mitsubishi 2.5L DOHC or Toyota 3.0 DOHC
Both engines are very similar - since the Toyota engine is larger yet produces about the same power, that means that the turbo is smaller or produces less boost. Which in theory means it should be more reliable, but also means it may use more fuel. This is compounded by the fact that the Toyota only has a 4 speed transmission wile the Mitusibishi has a 5 speed.

Thanks drdisque really appreciate the reply.
So in other words? In terms of reliable, toyota will be reliable because of having a "capacity" and produce less stress to produce the power. Hence built with low turbo boost. However, more fuel consumption will requires to produce "the power". But on Mitsubishi with lesser "capacity", it is able to somewhat bring more power in theory as the turbo will be slightly working harder and stresses the engine thus; these mechanism are not reliable. However it will be more fuel efficient compare of toyota, so less fuel wastage. Interesting! The Toyota car is actually having 65L capacity tank while the Mitsubishi having 70L. In conclusion, performance ride, Mitsubishi is better? but Toyota is reliable. Last edited by AlidMisli; 09-03-2014 at 06:58 AM. |

Yes, you have the theory right.
Also, you'll note that the Toyota is 200kg lighter, so in practice, they may actually get similar fuel economy.
