Don't you think your driveshaft should be a little longer and the clutch a little better? The way you present it, makes it look like a kiddie car to me.
You should also go for the german kind of engine regulators and spanish flies on the conundrum side of the fuel exhaust.
What's the total sum of everything you've put in it? How much is there left to do on it to get you rollin' in the mud again?
