I might need to have the one in my fit rebuilt or swap in another L15A VTEC shortly. I've got more than 120k miles on it and it's noisier than it was...
My understanding of the L13 I-DSI is that it has about 20-25% better Fuel economy esp in city driving conditions so by my calculations I would offset the cost of the repair in about 100 weeks of driving.

from reading further all I would need is ECU and Engine. Would have been fun for me to see some documentation of someones switching from L15 to L13

Have you been keeping up with normal maintenance? i only ask because my truck has 223,000 miles on it and still going. It is louder then it probable once was but the engine is still good. Of course I don't know the history of your car or the sounds it making. As for the swap I have not seen it done or documented on this site. It probable wouldn't be to difficult seeing as the engine was an option for the car

Have you ever done routine maintenance like valve adjustments or spark plug replacement yet?
Over time and usage, the engine's valve clearance will throughout its life (its common, nothing wrong with that in our Over Head Cam engine configuration). You'll hear the valves become louder over time due to them loosening over time and usage. Other valves often begin to tighten during that time as well. I'd recommend having this done first before trying to do some thing major such as an engine swap.
Swapping an engine because it is becoming noisy and less fuel efficient doesn't make sense unless there is a major fault at hand. Swapping to an even smaller engine makes even less sense to be honest. :/

How much would a valve adjustment cost ? I believe this maybe the solution to the noise I have.
Back to the replacing to an L13A1 I-DSI would net like a 25% increase in fuel efficiency. Saving me 750$ per year. I'm not sure how much the engine would be worth though. JDM RSX base K20s here are like 500$ so I guess the FIT engine would be arround that aswell. If it's only ecu and engine replacement it must not be such a big job. 4 hours ?
Thanks !

Just so you guys know I prefered my Toyota ECHO to this Honda Fit because of the fuel economy. I know the ECHO is lighter and faster than the fit but idc if the fit will be even slower I'd just like to pay less at the pump. It's a city car right ? I should be doing what a DD does best save cash at the pump.

although the piston dome is different, but, you have to change the wiring and
ECU too, here in indonesia many tuners done the other way, since the GD
that sold in indonesia is a 1.5L VTEC and 1.5L i-DSI, sooo many people done
the head swap from i-DSI to VTEC but, for i-DSI to VTEC it is harder to do
(but still to swap the wiring and ECU), since the piston dome must be a bit
modified to accommodate another valve seat on the piston, but from what i
saw VTEC piston dome is deeper, since there is a little difference too in the
compression ratio, so i think it will work, but the other problem is the ECU
program which in i-DSI it must accommodate timing for 8 spark plug.. instead
of 4.. so base on that you have to swap the wiring and ECU too..
Please Correct me if i'm wrong..
