What Gagues Do I Need?!
#11
so I need water temperture, boost, fuel pressure for sure right?! what about EGT and air/fuel?! can I just use the air/fuel ratio on apexi autotimer?! is it accurate at all?
well, I am planning on rasing the boost a lil bit in the future, and I want to get the gagues I need all in once, so I can mount them in nicely..
thanks for the suggestions..

You know, I have an EGT and I really never look at it...Possibly cuz I don't know what I should be looking at...I hear normal readings are between 1300°F & 1500°F I just set my max warning to 1500 and never look at it again.
As far as what gauges you NEED, I would say Water Temp first, then Boost right after.
Then after that EGT.

oh god....
<---notices a lot of people aren't mechanically inclined at all...
anyways, get a PowerFC (boost, knock{even tho its worthless} wtr temp, airtmp, timing, rpm), Boost, EGT, and Oil Pressure gauge.
The stock oil pressure gauge is junk.. i should know.. mine doesn't work anymore. They read pressure badly and the sending units are junk.
Its good to know your oil pressure, in case you happen to spill your oil on the highway, its getting way too hot.. (ie pressure rising like a ****) or if its in a good stable level.
Boost -.. its obvious...
EGT - like mjw said, its great for tuning.. and its way better than a A/F guage which doesn't do ****, but blink and make some girls loose their panties.. An EGT is used to monitor the temperature of the exhaust gases exiting the manifold.. (ie in your downpipe) the hotter the gasses are, the leaner the fuel mixture you are running, the colder, the richer. As with all A/F you want to have a Stoich mixture, a little more towards the rich side on our cars, since they aren't so forgiving to detonation. You will want to have a downpipe with a o2 bung and EGT bung welded into it when you upgrade your car, until then, an EGT is worthless.
You will find that you will need to learn how to modify your car correctly and which items you should purchase in a set order. I would invest in a downpipe first as well as a catback. Get an intake and ECU, then upgrade your intercooler and keep the boost stock. You'll have plenty of fun with it and keep it running for hopefully a year. If you go any further than that, expect to start shelling out cash.
A midpipe is NOT your friend unless you port your wastegate or have proper fuel.

so I don't really need to get a/f ratio if I got an EGT gague right?1
and did you mean that after downpipe, catback, intake and ECU, intercooler, the car will only run for a year?! if so, what will happend after a year?! that sounds scary...

you can't simplify the EGT hot=lean cold=rich like that. If you can't afford a REAL A/F ie (FJO, techedge etc) don't bother, but the EGT is still worth having. Chances are you won't be doing your own tuning, but its still good to have. I overdid it with gauges, currently have boost, egt, watertemp, oil temp, and oil pressure. the techedge setup ends up being about 500US after you buy the sensor and i am currently saving for that.

What's the point of fuel pressure, doesn't the gas guage do the same? Would oil pressure be necessary?
