I thought about posting this whole thread there but figured this would be more appreciated here. Think I should start a similar thread or maybe just a link to here? Looks like a 5th gear swap might work too and Im sure some of those guys would be interested.

I decided to pay a buddy some chump change to do this for me as time is not my friend and low and behold its a direct swap as far as the case is concerned. I'm not 100% sure about swapping individual gears but it sure looks possible. It's still gonna be a minute before I drive my car but as far as the question if fitting an 03-05 Civic Hybrid gear set into an 07-08 gear box OR you can use the HCH trans and buy a Fit clutch side trans case, 100% yes.
While I never have personally taken apart a trans before I wouldn't hesitate to do it myself next time (I watched). It took him 2 hours and he said it was easier that K series for reference.

Great info. Thanks. I would imagine the Fit gets a nice bump in fuel economy with some taller gearing.

Thank you guys too, this forum has been a great read and balance from all the go fast stuff, even with goals of 50MPG in an insight (loser!), I still get great advice.

That is exceedingly cool to finally have confirmed. Thanks for coming back to post it. I understand about time... it's not my friend, either. How is it driving?

Honestly it will be about a year before the car runs but I knew this group would love to know about the trans in particular. I won't forget though..... maybe someone else will try it and post their results here too? Anyways, thanks again to this group as well.

Late to the game here, but last month I swapped out a LX gear set into my EX transmission. I ended up having to pull apart every bit of the gear trains in both transmissions to make it happen in order to get the final drive swap right. Having never disassembled the input and counter shafts had me worried I'd mess it up....and I did. But I caught my mistakes, took it apart again, and got it straight.
I now have a smooth running transmission with a 700-800 RPM drop at highway speeds. The best result is the lower RPM makes the engine drone non-existent. I must say the MPG gain is really negligible. Maybe .5-1 mpg boost but certainly not much more. I also swapped out the D17A2 with a JDM D17A that has turned out great. I think my car will easily get another 50-75,000 reliable miles.
The old engine had 250K, a head minor head gasket leak (used coolant), needed a timing belt change, and used 1 qt of oil every 1,000 miles. It needed to go. I spent $450 on the engine, $300 or so in timing belt, water pump, gasket kits, fluids & such. I sold the old engine for $100 so for $650 I get to keep driving my smooth, comfortable, 36 ish mpg car 04 Civic for another 3 to 4 years only paying for gas and minor maintenance.
