turbo ?'s

i have a 98 integra. i want to put a turbo on it. but i have a few questions. i have only done basics to my car [myself] like intake, headers, exhaust, lowering. i would like to do the turbo myself also, is it going to be hard, or should i have a professional do it? if i do it myself what are some things to keep in mind? what is a good kit for my car? i have been looking at the FMAX kit from turbonetics, it looks the most complete, blow off, intercooler, injecters, etc.. it also says there is no cutting or welding. that is another question what kit really needs no cutting, welding, or mods.? last question does anyone know of a good web site to get to buy a turbo kit for a good price? any info is help

a good website would be turbokits.com i think they have a free ball-bearing upgrade with the fmax kit
