Turbonetics Single turbo.. saw it for less than $6000 and its simple bolt on and u just send your ECU to them and return it with new settings.. 
  
Negatives: it may only achieve about 380hp and at low boost.. (they state 450hp on website but i heard thats no safe with stock internals) 
  
Positives: Safer, wont blow your engine, cheap to install only 8hrs, ECU flashed and sent back to you by post. 
  
This is the direction im going.. when i get enough finance.
