I have driven my friends Tc Many times before. The car seems VERY heavy and sluggish. I have yet to be in a new SI but i’m sure they are a bit more nimble on their feet. My sis has a EX coupe and handles quite well for stock suspension/tires.As stated above, the SI has almost same HP as Scion and its N/A…so much potential. Take them both for a test drive, I’m sure you’ll know which one to buy. ---

clutch type lsd’s suck…they wear out and u have to add additives to your gear oil oh well… and the SI motor is already at high compression and pretty maxed out. i’m sure bolt ons may gain alittle more power not a whole lot more. just like the rsx, its already pushin good power in stock form which is great for a small 4 cyl. you probly only gonna get 10whp outta it with better exhaust and tune… maybe 15 if ur lucky which is a nice gain, but for the cost in parts it doesnt seem worth it being high compression u really cant boost it much. i havent heard jack on the s/c TC motor tho…so who knows what it can hold ---

I’ve seen at least one magazine drop their TC project car due to lack of an LSD as well as lack of aftermarket alternatives. Also there is a ton of bolt on NA and boost parts available for the newer honda K-series motors which are commonly producing 230-280 hp NA to 300+ easy with mild boost. The new K motors start out almost like a fully modded B-series motor (big bore, high flow head, massive main girdle). ---

as previous honda owner i am slightly bias but u cant beat the honda motors for power potential and aftermarket support. even in na form with basic mods and some tuning that k motor will make nice relieable power and rev like mad. plus i think that the si is by far a better lookin car ---
