GCP:
From all the questions you have posted it sounds like you REALLY need to do the following:
1. Come up with a base of what you are starting with.
2. Find a goal to achieve, light to light, 1/4 mile, autocross, etc...
3. Speak to several shops directly (like Secret Services) to get some ideas of how to obtain your goals.
4. Do searches on here and several other sites using the base information provided.
These suggestions will help you understand more about Honda motors and what can / can't be obtained with a Honda motor...
Good luck on your project...
p.s. - closed decks are great for the track, but I would not run one for daily driving... just my opinion...
