hey bro after reading what I wrote I guess I didn't really answer your question, alright I've been shopping around trying to find the best deals but here is the price list so far so parts are from ebay, craigslist, and my local speedshop.
turbo-$100
side mount intercooler-$50(guy just needed it gone

)
scavenger pump-$50(ebay) not sure about it but we'll see

oil lines-free i use them at work(best price ever)
heat shield-made it at work out of spare stainless-not needed but it's right by my gas tank so better safe than sorry.
all the fabbing is being done at my shop by me and our welder(good friend of mine)
bov-$75(is adjustable up to 30 psi,for later on)
that's what i'm up so far but there's an idea of what your up against doing a booty mount turbo build
I havn't got all the fittings yet but i'm sure it's gonna cost about $50 or so
