Re: new member 92 typhoon # 60
Welcome to the crowd....where are you located?
Some stuff that is always a good idea to have on a stock truck are generally "safety" modifications. This includes a Walbro 255liter/hr fuel pump, adjustable fuel pressure regulator, aftermarket boost gauge (stock gauge is notoriously inaccurate), replace the stock metal intercooler lines with 3/4" heater hose, upgrade the stock intercooler pump with a high flow Johnson or Jabsco pump, hotwire the intercooler pump to run when the key is on, and install a 160 degree thermostat.
This stuff doesn't get you more power per say, or really do much for performance, but it allows you to set the correct fuel pressure, allows you run have enough fueling at WOT (wide open throttle), run the truck cooler, and helps keep IAT's (intake air temps) down by running the intercooler constantly; just good stuff to have.
Take a look at

EDIT
Forgot to talk to the turbo question. There really isn't a set period for turbo replacement / rebuild. It all depends on how its been taken care of. If you look at your turbo, you'll see an orange rubber 90 degree elbow attaching to the front of the compressor housing. Remove that (along with the large intake tube across the top of the radiator). This will expose the compressor wheel, shaft and nut on the turbo. You'll notice that the orange elbow will most definitely have a coat of oil on it; don't worry about that, its normal. With your fingers, reach in and grab the nut and give it a wiggle up and down, then in and out. Play should be minimal. If you have noticeable slop (I've read 1/8" or so, but don't quote me) in either direction, it might be a good idea to start looking for a replacement at some point in the future.
