Man so much bad info in this thread. Crankwalk is over exaggerated. I have a 2g no crankwalk problems. If your that worried about crankwalk find an early 2g (an early 95) they are suppose to be safer as far as crankwalk goes Trannys are just fine, I beat and launched the shit out of my stock tranny...I'm talkin 6k awd launches at least every weekend and it held up for 2 years and is currently running in my friend's vr-4 galant. Forget the na motors, they will cost you more money to make them fast, if all your looking for is mid 14s, then a stock GSX is for you. Although it might be a little slower than when it brand new, a few normal maintenace repairs and a K&N filter will get mid 14's.
6k is a fair price, remeber talon's usally run about 1k cheaper than eclipses (just a brand thing I guess). If your looking for a good place to buy one, I like to get them of of dsmtuners, because you can search for that users previous post and see what problems he has encountered with the car and what he does with it. Oh, it has ok handiling (at least the GSX, never driven a GST) but like I said if your just looking for 14s, then you don't really need to spend any money on power mods, you can use that moeny for upgrading suspension.
As for a jdm engine swap, it's all just for ricers to brag, just so thery can say they have an evo engine. it is not worth the money, you could build a better motor for that price. And the cyclone manifold is also a waste, it might flow a little better but not nearly worth the price. Not to mention you will need a different ecu to run the cyclone mani.
