Joe,  thanks for reporting from the other world.   If I were doing a 
side port, cold side injection would not be considered.  I think all 
those convoluted passages would make it unlikely to succeed.  Also, the 
relative slow  velocity  in the four runner intake might contribute to  
the problem giving  distillation more time to occur. The velocity  
should be twice as fast blasting through our two runners.     I am just 
guessing here and don't have any idea of the time distillation  
requires or even if distillation is a problem in a n/a p port.     If 
this turns out to be a real problem,  the only thing that would change 
in my intake  is injector location.    I can live with that.     
Regards,  Jerry
