I'm looking for an EF for daily drive and autox, whats the differences between teh SI and the DX(weight, power, accessories...etc). I saw a white 91 DX for sale for 1800 with clean body and all. Is that a good deal? Do the DX come with PS and how many HP do the stock DX and SI got? Because I'm not planning to do any motor swap, maybe just some suspension items. TIA
