Hey you guys i'm actually new to this forum period, along with F/I.

Well, I just purchased my S/C and now waiting for it to arrive, but I have a few questions that I couldnt seem to find anwsers for. BTW, Yes I tried searching, but I didn't really see anyone ask this. Is it a necessity OR does it benifit you if you have the following

*Besides the S/C, a 9.5pulley will be added*

EGT gauge
Boost gauge
AFR gauge
Boost Controller
Turbo Timer ( not sure if i need this with a S/C? )

Would they really benifit me even though the S/C is basically still at stockish numbers. And if those 3 gauges are installed with the S/C, is a tune necessary? The TRD reflash is completely necessary though right? But yeah, tune with gauges?

Thanks in advance everyone! Really appreciate the input, im really new to this and would like to be informed beefore i S/C the tC. Ty!

 

the reflash and injectors are a must with the s/c, the gauges are nice to see where everything is at, no need for a boost controller on a s/c your pulley decided the boost.

 

you dont need a boost controller with a s/c as you wont have a wastegate. the pulley will decide how much boost you get. as far as the turbo timer, just think about that one for a while and im sure the answer will come to you.

 

^ LOL. Good one.

I would personally recommend the Boost and AFR gauge. At least with the A/F gauge you can see if you are running lean, or rich. The EGT isn't needed because the S/C doesn't run on exhaust gases like Turbos do...

 

an egt gauge could also be used as sort of a back up wideband device. you can use it to tell iff you are running rich or lean based on exhaust temps.

 

^ Thank you Brett. That I didn't know. I just figured the A/F Gauge would be the best option.

 

a/f is the most important gauge to have.

 

actually the turbo timer is sometimes called an "auto timer" and some n/a cars use it.. you can use it for the s/c so there's time for all the oil to drip and for your car to cool down.. if you have the extra cash then do it.. if not it's not a neccissity

 

EGT gauge - not a necessity, but will also aid in seeing if you are running lean (temps above 1700 F are getting sketchy with the S/C)
Boost gauge - not a necessity, but you will be able to monitor if you are making proper boost...and a vaccum leak if you get the boost/vaccum gauge
AFR gauge - NECESSARY!! You will need an electric wideband A/F gauge with an O2 sensor to monitor constantly for running rich and lean as these are most important for forced induction...especially S/C so that you do not detonate your engine
Boost Controller - You can only control boost with a lighter pulley...it's not electrical with the sc
Turbo Timer ( not sure if i need this with a S/C? ) This will work as it's only connected to the ignition...it can help a little after some hard runs, but not a necessity

 

either way its a waste of money, and not needed. spend that money on a water/meth kit insted.

 

Make sure you get an actual wideband AF gauge. I recommend the PLX unit as it has a better sensor than the more expensive AEM units. EGT isn't a bad idea IMO although the 2AZ motor doesn't run that hot usually. I RARELY see over 800 degrees C on a 360 WHP turbo car with timing set to 18 degrees up top via the standalone.

 

what about the one that hooks up to the O2 sensor. do those work good or even decent. does someone have one. whats the differece between them. i know the other one u have to cut and weld the fitting in the exhaust. NEED HELP BEFORE BUYING. im suppose to be pushing 9.5 psi and my boost gauge is telling me im pushing around 12 psi. so i need to know if im running lean or rich.

 

^ just buy the AEM Wideband. That's an option. I have seen it on ebay for cheap...

 

Hey you guys, thanks for the information really, VERY much appreciated, i'm a little more informed as to what im doing now haha. Just don't know where to get the gauges from. Dezod.com? And I almost forgot, but what about the tuning of my car when SC'd? Is it needed even though there will be gauges?

 

YES tuning is more important than the guages.. didn't toyota reflash your ecu? tuning is what makes the car run well.. gauges are there to inform you of what's going on under your hood..

 

They didn't reflash it cause I don't have the SC installed yet, I ordered it a few days ago, and just want to know what i need for optimal performance. I've seen WAY too many problems with the SC, but can't afford to run a turbo setup yet. So a reflash and a tune will make the car smooth?

 

Anyone have a recommendation on some gauge brands?

 

Whatever you do make sure it is a wideband with it's own sensor. Do NOT get the pretty lights on the gauge that tell you nothing ie. autometer or any other gauge that uses factory sensor. Those are worthless.

 

well it doesn't matter what brand you get for the A/F but make sure it's a wideband..
