It is the turbo made for the 5 ton. I will post pics this weekend. I don't know the numbers on the horse power gain, but it feels like twice the power gain of turboing a non turbo engine. On that note, my m35a2 did smoke quite a bit, black smoke, when you were getting into it, there is very very little smoke now, so I believe that I can turn the fuel up a bit. I will not turn it up until I install a pyro this year it also did not hurt that the gentleman GAVE me the turbo for free since he did not need it.
