Ask questions first no matter if u get flamed or not - cuz last thing you want is half a car and not being able to do ne thing with it.
You can get just the engine - but know EXACTLY what is coming with it. If it doesnt come with a full harness - dont get it. If it doesnt come with an ECU, dont get it.
You need more or less depending on your current trimline - ST or GT. ST ur going to need a new tranny and some custom work to do those engine mounts. Also, if u have an ST - get the front clip - you'll need so many other parts it'll be worth the extra grand. If you have the GT - u can use ur stock tranny but ur still going to need some here and there stuff. Plus replace belts, fluids, plugs...it gets pricey. Its not just a wham bam thank you maam kinda job here. Thats why like 10-15 ppl outta this entire site are doin it.
