4.5 20v / 0.7 8V

My first two engine creations, from one extreme to another but please find attached.

The idea for the 0.7L comes from the Smart Car Roadstar. This would be so quick in a very light weight sport convertible with the engine in mid range, along with rear wheel drive.

I know it is expensive in terms of hours to build, however when you look at the high prices of the smart roadstars, for highly tune small engines, you have to pay the price.

Regards

The reason that the man-hours are so high is that you've got the quality of the block set to +15. You can put that back to +0 with almost no effect on the engine, but with less than a tenth of the man-hours. In addition, the crank/rods/pistons are total over-kill, cast everything is more than sufficient in that engine. Oh, and stepping up to a three-way catalytic converter will give you an extra ~5.5 hp.
