can any one who did LS/VTEC swap on their EJ's tell me the expected expences of it? and its pros and cons?

Pros: There's really only two I can think of:
1) It moves quite nicely.
2) It's more reliable than a CR/VTEC
Cons: Very unreliable (especially if you're doing it yourself). The LS bottom end is made for lower revs than a VTEC head, so if you really want to take advantage of the VTEC's top-end power, you're going to end up pushing the bottom end waaay past it's redline over and over. Also, a good portion of them end up having oil flow problems to the head (due to the external lines overheating/clogging/just not working), which means 1) VTEC will never kick in because it is largely oil-pressure activated and regulated, and 2) there's a good chance you'll bake your cams. Basically, catastrophic engine failure is the most common end result unless you do everything correctly and keep a close eye on the engine after the job is done.
