ALL INCLUSIVE GUIDE for "What NOT to do" FI version
Don't use silicone hose for the turbo oil return line even if ATP turbo says it works. It's too soft and will tear near the hose clamps. -10AN SS braided or Goodridge 2-layer reinforced push-lok rubber hose are much better.
Don't use standard grade hardware on the turbo. Zinc plating will peel off, split lock washers will lose their temper and bolts will loosen. Studs, SS hardware and Nord-lock washers are worth it. Loctite doesn't work at those temps.
Don't assume that because AEM labels the 30-1910 FIC/6 as "universal" that it is even remotely universal. It's extremely picky about which crk/cam sensors it will work with.
Don't assume that your $500 PnP harness has been tested before you buy it. It probably wasn't.
Don't assume that your 25% larger fuel injectors flow 25% more fuel linearly because they probably don't.
If you plan to tune yourself, invest in a good OBD2 scan tool and software and learn how to use it or you will fail.
Don't buy parts from Ebay unless you know exactly what you are buying.

All bodies fit in the trunk...we have a lot of room...take out the tire.
Do NOT just buy some random turbo that wont even fit your flange, just because you heard it was the best turbo on the planet.
Don't just start randomly buying parts. Put some thought into it! (STILL havent decided my EMS yet....)
Don't be a tool and try to work without a 'Pro' helping you if you have never done it before.
Don't drill a hole in your Oil Pan without understanding WHERE it needs to be, what size fitting you need or without a type of grease to catch the small flakes of metal.
I got more...post em later!

I wanted to start this thread for all the forced induced people out there or people looking to be forced induced whether for racing or daily driving. Everything here is based on experiences that many of us have had and by and large, while there are some exceptions, this will serve as a guide of things, all inclusive, NOT to do.
I'll start, everyone else can add on as they see if, I do see this potentially turning into an epic and some will be banned, warned, etc for taking part in the festivities, check our allotment of infraction points before taking part, you have been warned.
-------------------------
You're boosting on the TRD ECU with a T3/T4 57trim eBay turbo at 8 psi of boost, stock injectors and no other piggyback but say the TRD ECU should be good enough and your AFR is perfect with the exhaust leak from the exhaust manifold....you're probably doing it WRONG.

Remember, our computers do have the ability to "learn" and conservatively adjust AFR's and timing. Thus, if a little thought, insight and risk are taken you can find ways that are unorthodox that may work.
Just to recap, my current setup isn't for eveyone. As stated b4, my turbo is waaaay too big for the TRD map, hence its not my daily driver.

Well as stated before in my previous post. Personally i wouldn't attempt to run the horrible combination of items you described in your post on my car. However, from personal experience, the TRD map keeps up OK with 440cc injectors and a smaller turbo. As ScionFred said, its important to have a good OBDII scanner (which i have) enabling you the ability to monitor just about evey sensor the car has.

You are doing EVERYTHING wrong. The TRD flash for the ECU is certifiably not made for the purposes of boosting a car beyond that of the TRD supercharger which is fails to do adequately.
You mentioned why more people haven't gone your route in your thread, and that's the reason why, it's a recipe for utter failure. The TRD map does not adequately adjust timing, fuel, etc. for 440cc injectors. In fact, the TRD flash was made for 410cc injectors, stock injectors are 330cc.
The stock ECU does have conservative relearning, it is NOT made to adjust to the needs of a boosted car, that's why there are management systems, if it were good enough alone there would be no market for other management systems for the tC.
It is clear that your personal experience mimics that of a guy who stayed at a Holiday Inn Express last night and miraculously wakes up and knows everything about forced induction.
Your car, your setup, this thread wasn't created for you, it is made for YOU and others like you who tend to do things the WRONG way from start to finish, to start again when the motor blows but carry on.

Don't ask Scionlife for advice. Most of the people here are not professionals and do not do this for a living.
If you are not paying a professional to install and tune your kit, do yourself a favor and
1. Read a few books about turbocharging before you ever screw one bolt.
2. Be friend a knowledgeable, experienced person for help and guidance.

Try to avoid using copper RTV on the oil pan if possible, use Permatex Ultra Black RTV Silicone Sealant. Copper RTV will give you false amounts of metal in any oil analysis you have done, leading you to think something internally is damaged or failing when in actuality it isn't. Try not to use any excessive amount of RTV as well, it may enter small opening and clog them, leading to a case where something is actually damaged.

Here's some good advice and probably obvious.....
Take your Scion to PTuning for a one stop shop F/I solution if you are not capable of this level of modification. Be honest with yourself. If you can't do it, take it to a competent shop.
