Why do you keep doing this?
Either sell your car, and buy the cars you really want, or just live with what you have.
It is a Mercedes car, underneath all those Chrysler badges.
It is not a Neon.
It was designed to prevent people from messing with the computers easily in order to muck up the works of the car.
If the computer detects that something is out of normal spec range, it throws a code, and shifts into limp home mode, instantly, so that the driver doesn't damage the car.
All of this would be understandable to you if you would listen to what we tell you, and have told you over the longest period of time.
This is not the car for you if you want to have big hp, and turbocharged thrust.
Please give up on ruining this car.
Your attitude makes me wonder if anyone on the forum has actually ever met you, and if you are just yet another internet troll running around loose, stirring up crap to get your jollies.
BC.
While I think I understand what you are saying, your comments don't at all address his questions about the swap. I don't understand all the hate here. Obviously the kid bought the wrong car. It happens to the best of us on occassion.
Your comments don't really make much sense either though--at least as I read them. The crossfire weighs 3000-3100 lbs (depending on the source) and yet, that's the same weight as most hot hatch cars that have the same or more power from a 4-cyl turbo. If we get away a bit from compact cars, into even bigger vehicles, you have the Hyundai Sonata which has a 2.0L 4-cyl naturally aspirated motor with 200hp, gets awesome mileage, and is quick enough for the street--or you can hit up the turbo model which is just as quick as a crossfire in a straight line and absolutely destroys the crossfire in mileage. Did I mention that the Sonata weighs more than the Crossfire. Or what about the Audi A4 Quattro that weighs a hell of a lot more than the Crossfire, but has a 2,0t motor and runs as quickly to 60 or the quarter mile as the crossfire? And it gets 21 mpg CITY. And let's not talk about the Mitsu Evolution which gets similar mileage (a smidge worse) as the crossfire, but weighs more and is in a whole different world of performance. I could keep doing this all day, but I think you get the point.
I also don't really understand your correlation between troll status and meeting people on the forum. I've never met anyone here (though I have done business with people on this forum), but I don't consider myself a troll. I speak the truth about the car, IMO.
Trying to get better mileage out of the crossfire is a wonderful idea, but throwing in a horrible 4-cyl is going to make a less-than-optimal situation far, far worse.
