    My 'rents came to town this weekend and I thought it would be some good father/son time installing a new up pipe, down pipe, EBCS, and fuel pump on my 05 LGT. Despite my old man and I not knowing very much, it went smooth. Of course, we made some goofs that others may benefit from such as, e.g., the following:

    (1) The 05 LGT's (and may other subies from what I understand) fuel pump assembly is located beneath the rear bench on the the passenger side. Some other fuel assembly (fuel level thinger) is located on the drivers side. Believe it or not, taking off the assembly on the drivers side does not double your pleasure or double your fun, it merely gives you exactly twice as many chances to strip fuel tank studs (which from what I read it a nasty problem). Fortunately, we did not strip any studs -- we torqued them down to ~3.2 lb-ft per LGT maintenance manual.

    (2) The sensor (o2?) located on the passenger side exhaust manifold should probably be reattached to the manifold after the heat shield are back in place since the manifold has a hole through it to run the wire - not after you have already coupled it to the manifold and routed & zip-tied (in tight spaces) the wire back up to the engine bay. We (because we are lazy) just cut out small portion of the manifold heat shield with an angle grinder instead of detaching and re-attaching the sensor (probably should have done this).

    (3) The heat shield bracket coupled to the two upper DP bolts on the firewall side needs to be reattached prior to installing a GS turbo heat shield. We already had the DP torqued down to the turbo. Removing the bolts, adding the heat shield bracket, and reattaching the bolts without removing the IC is probably not worth it - remove the IC in the future. Easiest way to get the heat shield positioned (when the IC is still there) was to feed it up along the DP from underneath the car.

    Random questionably useful notes:
    (1) We didn't strip any bolts (except for the stock turbo heat shield-- I think they were made out of bondo). We took our time, always used breaker bars, and PB blaster when a little questionable. Installed other bits (like EBCS) when bolts were soaking.
    (2) We dropped the drivers side and passenger side exhaust manifold w/o removing the crosspipe as many people suggest. It was fine.
    (3) No leaks - fingers crossed. Used GS or OEM gaskets with a thin layer of copper permatex on all gaskets. All bolts torqued to spec (at least within the tolerance of our cheap torque wrenches).
    (4) One of the upper DP-to-turbo bolts was missing a nut when we removed the stock turbo heat shield. After perusing the forums, this appears to happen fairly often to the stocker.

    Cheers,

    Sounds like you were successful at both goals...the car stuff and spending some quality time with dad, congrats!
