Depending on which civic you get it may have a small advantage in weight. My friend has a 4dr GSR with I/H/E/IM/p&P head and raced my friend in his 93 VX civic with a gsr with I/H/E/ CTR Intake Cam and my friend in the civic won. I thought for sure the 4dr would win. But considering the 4dr weighs in the 2700s and the civic weighed from the factory at 2094 I can see why.
