Hello im new to this forum and I know that the si and tsx share the same engine ( my dad has an 06 TSX) but I was wondering what else do they share. I love the way my dads car drives. And was wondering if the si is comparable. Though I didn't drive his car much with the stock suspension does the throttle response and clutch feel similar? Do they share the same transmission minus the LSD? In little under a year im really considering getting the new Si. I was looking at the new speed3 but after hearing about how the fuel pump can fail with just an intake I decided to look at something that can take mods without craping out on me. Thanks in advance.
