If that surprises you the retail on each should even more so, non-si (22100-5CC-003) is $776, the Si (22100-5CD-003) is $111.43...not sure how that makes any sense but that's what I've found. These are both less when ordered online through a dealer.
The Si flywheel is a traditional single mass unit. The non Si is a more complex dual mass flywheel that is built for comfort but heavier and less sporty. As stated above some (if not all) of the Si Civics have shipped with the dual mass flywheel wheel, possibly due to production issues.
anyone know of a way to check (besides opening the trans) to verify which SI's actually received a SMF, if any of em at all? VIN check?
Early on, Honda said the Si would have a SMF. They've since removed all references to that claim and it has been confirmed that at least one Si has a DMF just like the regular Civic. Not sure if this was a "typo" a while back or if there was a last-minute engineering change. Another thread mentioned that the SMF part number that appears for the Si is not actually an orderable part...at this time - or ever?
It will most likely just be pistons and rods, haven't seen a Honda yet that needed the crank upgraded under 1,000hp. Not being sarcastic either, even the old single cam D series engines with over 800WHP were using stock cranks.
I am curious how much power these internals will hold. I know they are small as hell but at least things like rods are forged. haha
Shouldn't be too hard. The K20/K24 routinely hit over 500whp on completely stock engines. These engines aren't related but my point is Honda typically overbuilds the engines a good bit.
