Critical parts of the engine must be re-designed for high-rpm bhp applications. The FB20 and FB25 engines wouldn't be able to withstand the high rpm wear. The FB25 would reach 200bhp with minor upgrades like the D-4S injection however it would not rev out like you would expect. I think they are sticking with a 2.0L engine for the launch in all markets so I'm expecting a slightly redesigned naturally aspirated FB based engine for this car. |
couldn't they just add longer rods than changing the whole borexstroke ratio? the F22C is also undersquare, but it feels great revving to 8000. 87x90.7 borexstroke with a 1.65 rod/stroke ratio.
we already know the FT86 is gonna have D-4S, so since it's gonna have a different head already the combustion chamber design will surely be different as well. i really hope they do a good job with this motor!
