I haven't put much effort into moding my engine as I am pleased with the power of the 3.4L V6 that came with my truck.  Though the other day I was beat by one of my friends in her 94 explorer so I have decided I need to get to work on the engine.  I have been doing tons of mods to slow it down, but a few to get some extra kick in the pants.  If I was that concerned with it I would have an S/C but since I don't do any towing or take any trips to the drag stirp I have yet to feel the need.  After a few more things here and there I will be happy with the off road ability of my truck and be able to spend somre more on the engine.  So far all I have is a Dynomax muffler and an Amsoil 3stage air filter.  I figured I would only get a maximum of 5hp out of a full exhaust so I just put the muffler into the stock piping.  I got the better sound that I love, and a dual exhaust will have to wait until after the S/C when it actually will do some good.  I'm waiting for the new version of the ISR mod to that and one of these weekends I'll get around to doing the deckplate mod.

I have a problem with getting my engine extremely dirty.  The best way I have found to clean things out is to *wait until the engine is completely cold* and after covering the battery spray the whole thing down.  I then spray the whole thing down with Simple Green cleaner.  A buddy of mine did this to his car and it worked wonders so I decided to try it.  I had to do a little extra wiping on the rubber pieces to get the dirt off, but the pictures speak for them selves.
