Ok I am basically hearing that a GTX swap is cheaper do to than out fit a GT engine with turbo...Keep in mind I am going to run as much boost as this thing can handle....I am shooting for the land speed record in an Escort...And by converting a GT engine I don´t just mean bolting on a turbo I mean changing compression and yada yada yada....
So am I right in this...

One thing to consider, the 1.8L runs a compression of 9.0:1. Thats a darn good compression for a turbo. In fact DSM´s usually run 9.0:1 or 9.1:1 in DSM´s modified for racing.
I remember reading somewhere that said the ultimate compression for a turbo was 8.5:1 because its low enough for crazy boost levels, but high enough to get the motor moving.
But consider leaving your compression at 9.0:1 and running 14lbs with some serious timing retard and 92octane. I´m pretty confident the little scort motor could handle it.
The trick is to increase your efficiencies. Make sure your IC piping isn´t too bid, and your intercooler isn´t too big. It causes too much lag. Dont be like the import guys and through a huge T3/T4 hybrid that´s so big the turbine wont even turn at idle. Getting a turbo compressor efficiency of 70-75% would be AWESOME. Same thing, the flow in your head will affect alot. Do a port and polish. Switch to titanium valve springs and valves...try to increase your readline to like 8500. Under boost you´ll just keep producing more power up to your redline.

I actually looked into this once *L* with the proper wheels and some more ponies the GT could nail 170 without to much trouble. any more than that and you need gearing along with HP. what kinf of speed you looking for?
If this is truly the way you want to go I´d do a custom build so a BPT VS BP wouldn´t really matter

Well I guess when I said the land speed record I didn´t really mean top end all that much....basically fastest quarter mile times anywhere....9´s preferably but i would be happy with 10´s....I mean I AM going to do this but before I can start buying things I have to finish my research...I would really like to talk to some of you guys who have done a turbo on like a conference call so I can ask question of several different people and they can argue it out

...I want most hp and torque out of a 1.8 as possible....even mess with gearing if I have to...I want to go full board man!
