do you realise your emissions are in the 800s even though you are using a turbocharged direct injected engine in 2013?? and besides, the car have the lowest running costs as possible while maintaining a high MTBF anything less than an economy of 20% doesn't cut it i'm affraid :/

Considerably yes

Coming from the person who told me to shorten the stroke: your engine is almost 20kg heavier

Very true, however not all of that is due to the revised bore/stroke ratio. 5.3 kg is due to the twin intake manifold. If I ditch one of the mufflers in order to get a similar loudness rating to yours (50.1 vs 50.5) that saves 3.9 kg. That leaves just a 8.4 kg penalty from the reduced stroke. I could probably analyze the difference better with your engine file.

Since I uploaded that picture I have made a few alterations making it lighter, slightly more economical and cheaper to build while losing just one hp. Here is my latest attempt...
