Just bought a 1990 Teg GS. I hear everybody talking about the LS engine, but when I go and look at the spec's for the RS, LS, GS (non V-Tec models) they all show up the same info except for the GS-R(V-Tec). If this is so, why does everybody keep talking about the LS? Couldn't you do the same for the GS or the RS even? Thanks
