Nice to have another engine builder around.
I would just say that the Mugen chip is not what I would consider to be a "really well done computer." Basically it's tailored to a Formula 4 crate motor. There used to be a writeup on why exactly the program is not the greatest for street-driven cars but the page has been taken down. This is all academic however, since the only Mugen program out there is for B-series cars.
Oh and wazup, you're right about the stroke being 90 mm and not 95. My bad. I already said the largest a D block could be bored out to is 79 mm though.
