T-cam? Never heard of it. unless this si some new-fangled way to say dual cam. Sorry i'm a DOHC man myself. I don't know alot about the saturn power plants. They're kinda like the Saab of the U.S. Kinda quirky and misunderstood. Everyone keeps telling me about this 1.9l 300HP engine. I'm sorry but i'm gonna have to call on this one. Unless it's at least twin turboed it's not gonna make that kind of power. (factory nitrous?) Not from a saturn. Even the 2.8L Bi-Turbo I-6 Used in the S4 doesn't put down that kind of power. Even if it was a 20v DOHC I-4 i doubt it'd put down over 250hp. They have to have some serious technology to be boasting that kind of power. The ION looks to be a good platform, but from the looks of everything i'm seeing it looks to be the 20 something version of the toyota camry. Ergo a accord for the "matrix" crowd. If you follow me...
