FJ20DET would probably easier due to the fact that a 13B is considered to be 2.6L (due to rotary 2 stroke-like design)

Even if the 13B would be more appropriate for weight balance reasons.

The 2L turbo was probably only registered because the Ute is considered a commercial vehicle, not a passenger car. I'm not sure you could do more than 1.8T in a Sedan or Coupe in NSW anyway.

Even my CA18DET was scrutinised by the RTA staff when I first registered it. Even though the Engineer gave me a certificate. The guy behind the counter said.. "That only just fits within the guidelines".. and gave me a dirty look.

ps. This was in the days when the RTA knew how a car worked. These days, RTA staff are glorified checkout chicks.
