Hm, so taking the Insight's final drive and putting that into a HCH1 transmission, and then using that in the Insight would maintain the same fuel economy, but provide better gear ratios for acceleration? Sounds interesting, I will have to keep that in mind for when the IMA dies. HCH1 trannies are like $250 at the local junkyard, the IMA bypass will cost $100-$150 if I remember correctly. So that's $400 to permanently eliminate a $2000/10yr expense. Not bad, if I could do it myself. Sounds like a fun project and learning experience.

Will be inspecting the red Insight in an hour!!

Just curious, what RPMs will your K-swap spin in 6th gear at 50, 60, and 70 MPH?

I've always wondered what MPG one of those short-geared Honda Fits would get if someone swapped in, say, an Insight or original CRX HF transmission.
