better parts

[Vmix06]

hi every1 i own a 06 tC and the only upgrade i have is the TRD exhaust system i have plans to put a turbo but i need advice on the internal parts of the engine such as pistons, cams, rods, carborator, headers, intakes, and itnercooler.

if there is anything else that is important that i left out then please let know

[bwood87]

Haha a carburetor, I think the last car in the U.S. made with a carburetor was in the early 90s. Your car is fuel injected.
With a turbo you will not have headers, you will have an exhaust manifold that the turbo connects to which is specific to the car and the turbo. Building up your internals is only necessary if you are going to put a lot of boost in there. You can hit 300whp without building up your internals.

i thought that u had to upgrade alot of the engine for a turbo so it will run smoother without hurting the engine badly
and the carborator i forgot alot about that bc i had an older car befor and i had forgotn that the tC was fuel injected i just get used to saying carborator lol

[bwood87]

No, it really all comes down to how much you want to boost. A lot of the turbo kits claim a factory set boost from 5 - 8 PSI which can be run easily on a stock motor. If you get over 10 PSI and still want to go up thats when you want to start worrying about building up the internals. I do not know exact numbers, but you could probably get to ~14 PSI before you run the risk of breaking stuff. I think I saw a tC with a little over 300WHP at 10PSI.

wow i did not know that so what company makes a good turbo kit for an everyday driver that wont cost alot of money
plus ive heard some ppl saying that they have an on and off switch for the turbos but im not sure if thats possible

Just check out TurboKits.com Turbonetics Scion tC Turbo Kit & More. I have not really been looking for one so I do no know too many good sties for them.

You sure can with either an auto or manual boost controller. You can also have a engine management device that switches between multiple tunes. Have one for fuel saving, daily driving, racing, and anything in between.

Yeah, the only real problem is can you keep the boost beast from talking you into cranking the boost just a little higher Like bwood87 stated, it is best to get multiple profile maps tuned by an experience tuner. Be sure to stick to the map's profile, IE race map- C16 gas, street map - 93 octane, etc.

ty u guys having multiple maps like yall said for fuel, saving racing, and everyday driving but would i have to install a switch or some kind of device that would change the maps or would i have to hook it up to a computer and change it there

[bwood87]

It depends on the unit that you buy. There was one that I saw that had a switch for two different maps. So for that you could have like dail driver and something that is faster but still works can run on premium fuel. Then if you head to the track you can go in and swtich the map with a computer. Same thing if you plan on going on a long trip, just switch out the map to a fuel saving one before you head out. I have no clue what unit it was though so I would just reasearch as many as you can.

[navylife59]

The Greddy Ultimate (what I have) allows you to set up to 4 maps according to dip switches on the side of the unit. Not very convienent. You can also upload a new map to the EEPROM to be the Active map.

[bwood87]

I'm sure there is a way to make a remote for the switch if one so desired.

So whats the better thing. a turbo or a supercharger... cause i dont really know....

[bwood87]

Depends on what you want to do.

[Heavy Chevy]

Not anything crazy. A lili bit more power

[Vmix06]

well from my point of view the turbo is better but that is my own opinion hence this thread i started lol

basicly what ur saying navy is that if i put a map into the EEPROM it would be the default map?
Plus do u have a link for the Greddy Ultimate or do they still have it on there site?

[Heavy Chevy]

Oooo. I wuz told dat the turbos can cause problems if they arent properly installed.But i don't know. Ima probly do what eva cheaper

if you want a lil more power, go with the supercharger. it costs a little less in the end and it wont shorten the life of your engine. i want more show than go myself. thats why im saving for the s/c. plus for the 05-06 tC it's $1900. good deal vs turbo for my overall goal.

As in EEPROM for the Greddy Ult, then yes, the map that you load using the software becomes the the Acitve map in the EEPROM.

Anything improperly installed will cause you problems. Turbos have more of a propensity to cause damage when thing go awry. They put alot of stress on an engine. It has to be controlled and tuned correctly. A supercharger is a tad easier as it has a linear boost profile that is locked in by RPM, where as, a turbo can be changed by trim or boost control.

Nice i wonder if it da same price for the 07-08s
