Hi. Can some one tell me what the difference is between each eclipse? What is the difference in the RS and the GS. I already know the difference in GS-T and GS-X. Could you tell me the differnce in horse power, if any. and specs between the two, or send me to a website that can. The mitsucars.com only has specs for there new cars. and also what measures can be takin to do a GST engine drop into a GS/or an RS. Thanks in advance guys I really apreciate it. I'm sort of at a lost as the only eclipses in my entire state are either GS or RS, no lots have had a GST or GSX. Where as I would have much rather bought teh GST and done a single turbo upgrade I am now at a loss if you could help, that would be much apreciated. Thanks again in advance!
