GSR light weight with 220 hp with the lsd tranny I think would take the RSX without a doubtType R verses SI would be close - Type R weighs more but has more power so I think it balances outmiss read the question sorry - out of all of them I perfer Civic SI its a good platform to build on - it's loved highly by the after market world and with a itr motor it will take the itr anyday
