****. So far I haven't had any luck with toyota. Apparently no one knows the stats of their product. Will keep you updated more on this. Also, we can do whatever we want to the engine. The weak link is the transmission.
So, I have been E-mailing a guy at a Toyota dealership who has a friend who works as a Toyota Engineer and this is what he said:
I have talked to my friend and Toyota does not publish a maximum power spec for the transmission, the belt is an alloy of some type, no actual specifics on what the alloy is made up of. He is going to check further however he doesn’t think he will find much more here in Canada.
So if the CVT actually works with the turbo, then you will be unique to have a turbo Corolla with a CVT! I am going to have to email someone higher than the dealership so once I get more info, I'll post it!:thumbsup:
Why would Toyota accountants allow a transmission to be designed to be strong enough to withstand power levels it was never intended to? That would unnecessarily increase production costs, which would reduce profit margins and that is a big no-no, especially with an economy car.

Original equipment warranties don't extend to 200,000 miles or more and over-aggressive driving is considered abuse that is not covered by the warranty. Toyota accountants are not going to allow parts to be over-engineered, which raises the cost of production and the selling price of the car. That would be death for the sales numbers of an economy car.
Not about the warranty. You build a car that only lasts to 60,000 miles and you go out of business.
Plus, Toyotas Corollas are always a little more than say, a Focus, Dart, etc. Why? Toyota builds them to last and that is in the price. That's what you pay for when you buy a Toyota.

You've probly bought a Toyota for the same reason everyone else has, their reputation for reliability and longevity. The only way you get a reputation like this, is to overengineer some parts.
If done right, this engine can handle a small amount of boost and still be more reliable than most of its competitors. I don't think anyone is thinking of throwing a ton of boost at it and expecting it to hold up.
First, I was confirmed by Toyota that the material of the CVT transmission belt is made of "reinforced polymer material".
The second thing is this email I received from a Toyota mechanic and his thoughts on turbocharging this car with the CVT: [FONT="]
In most cases as long as you have the correct fueling etc and don’t run max boost for a long period of time you should be okay in my personal opinion. Please also remember that my opinion has nothing to do with Toyota warranty etc.
Not quite the definitive answer i was hoping for, but I have been considering the fact that many cars come with a CVT pushing much more horsepower than the corolla. So, if it is built well, and we dont go crazy pushing the limits, we should be fine after all
The new Subaru WRX STi is releasing with a CVT, so it looks possible for a CVT to handle power; however, Car and Driver blasted it for noticeable delay to downshift going to wide open throttle.
It's a steel belt. "The steel belt consists of elements and 2 rows of steel rings. In contrast to chains and belts which transmit power through the use of tensile force, the steel belt uses compressive action (pushing force) of the elements to transmit power"

One thing I read is that Toyota limited oil pressure to eliminate as much parasitic drag as possible without creating belt slippage. I think that kills any idea for a turbo on a CVT without modifications to the oil pressure valving.
UNFORTUNATELY NOT MUCH IN WAY OF SPECS AS IN "MAX TORQUE ETC, (APOLOGIZE FOR CAPS AT WORK), IT HAS GIVEN ME FOR PULLEY SPEED RATIOS (2.480-0.396) REVERSE (2.604 -1.680)DIFFERENTIAL GEAR RATIO 4.761 TAKES 7.47 (US QUARTS) CVT FLUID FE. WIRING DIAGRAMS, ETC BUT NO TRUE SPECIFICS. IM STILL SEARCHING I MAY GO INTO THE TECH BAY AND GO THROUGH ALLDATA (TECHS BIBLE)

I have seen a few member install it but no one has done a dyno run yet to see whether or not any gains have been made. I have a acquaintance at my Toyota dealership who told me that all mechanics there use the K&N drop in air filter. I know that the K&N Typhoon intake supposedly does increase MPG and HP, they did provide a dyno sheet but always take it with a grain of salt. Until I or someone I know and trust on the forums does a dyno run I won't believe that it will increase HP or MPG.
Ok so after reading everybody comments I think I'm just going to do a intake exhaust and a computer chip which should remove the limitter too. What do u say guys??
I own a 2015 Corolla its a nice car over all but needs a lil more hp lol. Turbo and super chargers are too much for this car I think intake exhaust and chip should be good enough. After all most ppl buy toyota for economy Cheaper maintaince and less issues with the cars period.

There's a site called https://www.deroure.com/ that sells the supercharger kit but the only thing is that it's in a different currency and not sure if they will ship to the use but it's definetly the magnuson r900. on toyota nation this guy ordered one but idk if he lives in the US. Also with supercharger do you know if the LE models transmission can handle the power. Also i believe we would have to flash or reprogram the cars ecu to handle the supercharger.
for the supercharger kit alone it's 4k plus all of the custom stuff you'll have to do and possibly change the belt in the CVT transmission for the LE model (if possible) maybe around 6k - 8k total
Lol dam. U serious about all of this hunh?? I'm just trying to do minor upgrades for now. Like a intake, exhaust system, sway bars, springs, and ecu chip. I should make my 2015 Corolla s Hp close to 200. Stock they come with 132hp.
