Is there any sport transmission upgrades that are compatible with the USDM GKs? I've got a short shifter installed and a lightweight flywheel would be a nice upgrade.

 

hey where did you buy your lightweight flywheel and how did you get it installed thanks

 

oh wait, i read that wrong sorry

 

Knowing from the 9th gen Civic Si anytime you throw a lightweight flywheel on these newer Hondas the stock ecu will go into limp mode. You would need Ktuner to be able to turn off the misfire that a lightweight flywheel creates
