Anyone know if the ek9 chassis identical to the other ek chassis; such as ek3, ek4 etc?

 

they should be the same, other than the front lower which is stiffer

 

If the comparison between the EK9 and EK3/4 is the same as the ITR and lower Integras, then the chassis is different in that it has a lot more reinforcements.

Hope you do know that you don't have an EK3 or EK4 here (more than likely).

CTR has rebar instead of the large bumper bar that the lower trims have. The USDM EJ6 hatches have this thick bumper bar (as do all other USDM Civics).

Sway bars would fall under suspension. I was under the impression that the OP is talking strictly about the chassis of the car and the chassis components.

 

The CTR has the following chassis reinforcements stock:

Front Upper Tower Bar
Front Rebar (replaces bumper support)
Rear Rebar (replaces bumper support)
Front Crossmember Brace
Rear Hatch Wall Brace
