I've been told a few things about propane injection over the years,but left to come to my own conclusions.I was told it does the same thing for a diesel that nitrous oxide does for a gas job.That it's shot in,and gives a boost of power temporarily.Is this true,and who makes these systems?What type of bottom end,and head work will I need to do to put one into a 79 300cd nonturbo car? Is it just plane not recommended,and why?Any input from anyone is greatly appreciated.Still just kicking around ideas for this car,and it occured to me a little while ago.
