Are the exactly the same? I'm guessing so, but due to my inexperience, being only 19 and all, I don't really know.
I'm asking so that I can do all the research into 3s-ge to 3s-gte conversions before I'm off my P's. Save up and do it as quickly as possible. Also would $300 be roughly the right figure for getting the loom wired in professionally?
