I am beginning to source parts for my S30 - L28et swap and already have the long block 
(P90a - F54), but need everything else.  My car is a late year-260z (December 1974).  I am also looking for advice on transmission options as I have found endless information (somewhat difficult to sort through) on options.  My car is an automatic if that makes a difference.   
  
I am looking to buy: 
  
Transmission  (T5- or other??) 
Manifolds (Intake and Exhaust) 
Turbo 
ECU 
Wiring Harness 
Dizzy 
Fuel Rail 
everything else  
  
I appreciate any help or advice!  Thanks!
