I'm all about V8 conversions and engine swaps. The first choice is the 1uz-fe Toyota V8 or Lexus V8 if you prefer that. I also do 3uz-fe swaps. Lots of wiring including Immobilizer bypass. Next choice is the LS1 Chev V8, or its big brothers the LS2 or LS3. As I do lots of wiring I also do a fair bit with aftermarket ECU and wiring including the odd V8 Sprintboat.
