my name is manuel, i am 20, live on my own with my little brother, work at the nissan proving grounds, have a lot of racing experience, and need your help. 
  
i have a passion for Z's and am dying on the inside due to the current lack of one. i am ready to purchase another one but first need some knowledge shared with me. 
  
i am ready to buy a JCI kit, and am negotiating with a local yard for an engine tranny and ecu, and am about to purchase the beast itself. 
  
the questions/concerns i have are as follows: 
1. what would work better a JCI or JTR kit 
2. what model and year of z would work better with the kit 
3. what ls1 is ideal for the kit 
4. what did you not ecpect to run into that i probably will 
  
and any other hints will be greatly appreciated 
thank you for your time
