The 2015 Honda Accord (all trim levels) is 191.4 inches in sedan form, and 189.2 inches in coupe form.
The 2015 Honda Accord V6 models are timing belts. The 4-cylinder version uses timing chain.
I see no reason why you can't.
It might be possible. Both cars have the same bolt pattern (5 x 114.3), and the Accord might be able to accommodate the larger wheels/tires that are on the Si.
The 4 cylinder has a timing chain and the V6 has a timing belt that must be replaced every 105,000 miles.
