RS2000---->RS Cosworth

Hi, I'm new here, and this is my first post,
and mainly it is the most important.
so, I have a Ford Escort RS2000 model 94, and I want to change the car in almost everything, I want to build an Cossie on the RS2000 Shell
First of all, IS it Possible??
so my qeustions are:
1) Is it possible?
2) If it is, what the changes need to be?
3) I'm more intrested in the YBT engine, with the bigger turbo, is it possible to fit this engine in the MKV/IV shell? again, what are the changes needed to be done?
4)a. Is it possible build an 4WD with the 3 diffrencialses on the FWD shell? the front diffrencial need to be changed?
4)b. Can I build the Cosworth with only Front Wheel Drive System, I mean the original system is need to be chaneged because of the engine position?
5) The MT75 gearbox need to be fitted here?
6)In generally, what are the parts, I need to o buy for this project? If it is possible, please, write E-V-E-R-Y-T-H-I-N-G-!!!?
7)IF SOMEONE HAVE AN ICQ PLEASE add me to his contact list with the number 234893758
Thank U everyone for the help!

BTW, if someone mean to ask why Im not preafer to buy an original Cosworth , the reason is that in my country (Israel) the is not an original ESCORT COSWORTH.
again, thank you everyone!
