Your swap doesn't make a whole lot of sense. I know I'm beating a dead horse here, but there is a much bigger difference between Accord chasis and the Prelude chasis than you make it out to be. Either your making alot of this stuff up or you are doing some serious hacking and welding to do what your doing. Fifth generation Preludes do not share much of anything with any other Honda. If they were as similar as you say, don't you think the Prelude would have been built on the same line as Accord? The Prelude and S2000 are the last Honda vehicles to be built entirely 100% in Japan. If the Prelude was so common to Accord, they would have been building it in Marysville for the last 20 years. Remember, Honda is the most efficient automobile producer on the planet. If they could consolidate operations with similar tooling and designs, they tend to keep the cars together. Prelude has been built on its own line for the last 10 years.
