    help with gauges

    looking to get gauges but not sure which i need.

    1 boost/vac
    2 EGT?
    3 Oil pressure or Oil temp?

    what exactly does EGT gauge measure?

    any advice would be great.

    EGT will mesure the gas temp. if its high then that means a lean Air/Fule mix
    works like an air/fule gauge

    boost gauge is a must

    egt and oil pressure really only needed when you start to get more serious in modding

    if you get an egt make sure to put it close to the cylinders not in the uppipe that to far away and will be useless

    thanks guys for the responses.

    i dont plan on any serious modding.

    i just think one gauge will look silly on the pillar. i want at least 2 i think. any other recommendations?

    just get a single pod then... If you dont plan on serious modding the egt and others are just waisted money. Boost however is nice to have. Plus the tripple gauge pods look ugly imho.

    now the tripple gauge pod that goes in the clock space looks good. Just not the tripple a-pillar ones. Of course this is just my opinion.

    I don't think oil pressure is all that much of a waste of money. It will tell you something is wrong way before your idiot light comes on. I realize that something shouldn't ever really go wrong with your oil system if you aren't heavily modding your car but its not a bad thing to have just in case. Maybe a volt meter if you just want another gauge so your car doesn't look funny considering the stock gauge cluster doesn't have one.

    I personally am going with oil temp. I don't plan on going past stage 2 so oil temp will be beneficial when the weather gets colder i know when my oil is good and flowing so I can press the go pedal harder

    that depends on the gauge they all use different sender units (if electric gauge) mine was a pita to mount under the ic, but they sell oil filter sandwitches for sensor hook ups which I think would be real easy if you are capable of changing your own oil

    do a search and you will find plenty of turorials on how to install them

    wow that seems like it will makes things much easier. do these hook up as easy as they look? are they acurate and safe?

    From what I understand, the sandwich adaptor (about 60 bucks) is fine for oil temp but not as accurate for oil pressure. The galley plug (about 9 bucks) under the intercooler is much better and more accurate for oil pressure.

    Thre is one "gotcha" that I have found for the oil galley plug is that the part from Suabru is 1/8 PT (japanese standards). Most "cheaper" gauges such as autometer, VDO, glow shift etc. use a 1/8 NPT (US standards) which is almost the same but not quite the correct thread. You will cross thread the bolt if you try to put it in. The gauges that will fit in the subaru galley plug are the expensive japanese ones such as Defi, Greddy, Apexi Etc.

    Unless someone makes an adapter that will fit a 1/8NPT to a 1/8PT then your only choice is to go sandwich adapter or an expensive gauge.

    my prosport threaded just fine into the gallery plug but I had to make a brass offset since it would not fit screwing straight in
