I don't get how if you have H/C/I gear and S/C a eclipse could even come close unless it was extremly modded to the hilt and that would take some deep pockets. I knew some guys with some really built eclipses, and they weren't basically modded they had as much if not more invested in thier cars as everyone else with domestic muscle. If you want one to really run, it's just like on our cars, everythign needs to be modded.
The factory turbocharger is quite small and and still has a lot of lag, along with the small factory intercooler and exaust. You can free up some pressure by getting better exaust and let more air in with a better induction, that way it will spool faster and then you can increase boost, but then you increase heat, so you then need a bigger intercooler, and those things arn't cheap. With a small turbo, your limited, and as you increase boost, but at a certian point, your heating the air more than boosting and backpressure increaces so your not making that much power, so you can get a bigger turbo, not it takes even longer to spool but once you get boost, wow does if fly, but then there is fuel. Bigger injectors, pumps, rails, this adds up. Of course, then tuning becomes more critical, and expensive. Go on any site or in any store that sells this stuff and start adding it up, it's expensive. Then the parts that were designed for 200hp and 150tq suddenly start snapping. OMG can they be quick, not only down the track but quick to empty your bank account. What I am trying to say is that if anyone thinks they are going to go out, put on a fart can and cai, and turn the regulator up to get more boost and think they are going to go out and play with the big boys has another thing comming.
