Though having fun with all of that, I might go ahead and take 2JZ-GE VVTi block you will have left over, and build that shortblock over the facet with the 3.4L package when time/spending plan permits. You can certainly use the GE block for a base for this, and install the 2JZ-GTE VVTi head to it in the event the time arrives.l cant see any purpose
