Lets make a Yaris Real Fast.....
Hi guys-
New to this board. Hope all is well with everyone. Happy Thanksgiving as well. Im coming from a domestic side of all trucks....silverados, avalanches, escos etc....blown in everyway turbos and sc's. Now. I have been reading bunch of stuff on this board but I cant find exactly what I want to know. Maybe you guys can help me. Whats the average whp of a supercharged Yaris out right now? STOCK motor. Whats the average whp of a turbo'd Yaris out right now or custom setups? STOCK motor. I seen up to 300+ whp on some of them but these are worked motors. What has been the quarter mile for these stock motors that have been SC'd or Turbo'D? Now lets say we got the turbo custom setup, who do we use for tuning? I see emanage is that the one? or something better? Same would go for the supercharged version I take it? I dont know which route im going to go, because I would like to get this little buddy into the low 13's high 12s with a 0-60 to 5 secs-6 secs. Best would be under 5 but I dunno. If I do a SC'd though, I will go rotrex on this. Cause its pretty much a turbo. I dont know what numbers we need whp-wise to get to this. or has anyone done this already. I dont know what the 4 speed tranny can handle cause its auto, I dont know what the stock motor can handle. Maybe you guys can help me out on this. I would appreciate all your inputs and whatever else you guys know about. My idea is building a good kit for myself for a stock motor without blowing it and possibly selling it perhaps. Then once I get it done, do the motor bullet proof. I have alot of experience on doing production kits. Money is not an issue. So whatever you guys tell me we need, its all good. Thank you for your help guys. Jon |

If money is not an issue, why not re-build the engine, get it a little stronger by replacing certain internals so you can get the boost higher and then get the speeds you seek... Seems like 12's in the quater with a bone stock engine and a turbo or SC mounted to it would be pretty difficult, but it DOES sound like a fun project for you. I hope you enjoy it.
There are a lot of people here who can answer some of your questions, I just wonder if money is not an option... then i may go about it a little different. Enjoy the yaris, and welcome to the site. Rock On!

You said you have a lot of experience, but you also said a rotrex is "pretty much a turbo". Those two statements don't really go together?
If money is not an issue, why would you want to keep the motor stock? 12's is not possible on an unbuilt motor, in my opinion.

Rotrex was developed to be a turbo, which for the most part it is, it just runs as supercharger example being run by belts/pulleys. it has pretty much the SC low rpm power but maintains the mid and even high rpm power bands like the turbo.
Rotrez is being used by many manufacturers today, some being put on the german manufactured vehicles and many manufacturers are coming out with their vehicles rotrex based replacing traditionally their turbo based vehicles. Hence Jackson for instance a supercharger kit manufacturer has replaced their programs with a rotrex based kit/s. The reason I want to keep the motor stock in the beginning, is to be able to take my kit and possibly turn around and sell it in the future for stock based cars and perhaps leave room for the individual to upgrade their kit and or motors. So thats the reason I asked what would the stock motor and tranny handle at close to maximum whp.... drivability is also a concern here for example daily driving attributes. Your motor is built for the most part Garm. But I wanted to see what we can do stock wise. and lets say the numbers are 170-220 whp on a stock motor/tranny, capability wise, what would those numbers produce on a 0-60 or perhaps on a 1/4 mile? Hope this helps. Thank you guys. PS: a 5 door Yaris is what I have. Not the sedan or the 3 door. |

If you are looking for those numbers turbo is the only way to go unless you build your motor.

I think you are a year ahead of your time. The Yaris is too new to have the following that the older cars have. The aftermarkets are geared for numbers which is not the case for the Yaris. Look to other countries that have the Yaris numbers and therefore the following. Good luck.

Anything higher than 185 whp, I think you'll eventually blow up your motor.

I had some damage after driving 8-9 months at 8psi and 183 whp on the stock motor. Cylinder 4 was showing some loss of compression. It would have eventually failed. So I think your 170-220 on the stock motor is outside the range of reliability.
I think few people have done/will do mods to their car that dramatically affect the longevity. It will take a year of "proving" a kit before people will be comfortable enough invest in it. That's why the Blitz compressor is so popular.

Slowy getting there

Also if you think any extra mods you car doesn't need what are your plans with your car?... Are you going to keep it completely stock? Because the Yaris has everything to be a running vehical as is and will last a long time, so according to you any thing someone adds to or changes on their car is "rice". Why are you in a F/I thread if you think that a turbo on a Yaris is "rice"?

I think what he was getting at, is that it is rice to spend all that $ to turbo a Yaris just to drive it to work and back. I can agree with that, we are talking about a economy car with a $12-15k price tag. Dropping Over $3k in the motor or more is kind of crazy just to get more pep out of it UNLESSS you actually plan to utilize that power for what it is meant for... to race.
The flipside is the aftermarket industry would be super weak if only racers bought performance parts. The only person other than myself from what I have seen on this forum who utilizes the extra power seems to be Tamango. Even hitting up the dragstrip every once and a while is ok. Spending $ to build a motor and turbo kit just to post up whp numbers IMO is not $ well spent. If you want to get to 7-11 faster there are better ways

Good thing everyone doesn't have your logic. You don't HAVE to just race. If you were, why even build up a yaris or xA to purely race. That'd be stupid. Want to know the beautiful thing about the yaris? You can still be boosted and have a great DD that makes 35+ MPG to 7-11; atleast I can. Tamango has a NA xA, but drives his hair stylist mobile nowadays. He's trying to sell or sold his xA. Last edited by PETERPOOP; 12-06-2009 at 05:22 PM. |

hmm so he removed his turbo set up? He had a whole thread on the Scion forum about his boosted set-up.
Im not talking about building a race car, but spending a lot of money to make power should have a purpose other than for daily driving. My car is a daily driver, been racing it HARD since 5000 miles on the odo, it now has 102,000 miles on it. And it gave me 34mpg on a recent trip. 200 miles using 6.05 gallons of gas.

I never seen a Blitz set-up put down more than 121whp though on our dyno. It wasnt until I introduced nitrous that I was semi satified. The whole belt issue and sheering crank pulley pins got annoying so I got rid of the supercharger set-up. Using the round end of a good 1/8th ince drill bit provided a good upgrade to combat shearing the crank pulley pin. I was the one who came up with that idea years ago. Here's a link to Tamango's old thread http://www.scionlife.com/forums/showthread.php?t=118234 cool ideas by him. Im assuming we are talking about the same guy. Good to see people autocrossing and utilizing their upgrades, I just wish I'd see more of you guys do that. There are a couple of Yaris' around here that autocross but havent seen one on a road coarse yet. There was a Turbo Fit at the time attack in NJ this past summer, I was excited to see that cause I didnt feel alone for once lol.

once you reach double the wheel horsepower, you'll run into longevity issues, i'd think
safe(ish) would be around 150whp with a turbo the blitz kit seems generally happy around 130-135whp range w/ bolt-ons

I would agree from what I've seen, 155-160 is about the most you'll get with stock internals for long periods of time.
With that said, if you can find a way to shed 600 pounds, that can still be a 12 second yaris. (maybe not with a slushbox, but it will still be close). Although to lose 600 pounds, you'd probably spend more money than building out a motor. |

Building the bottom end isn't that expensive if you are looking for those numbers however when it comes to building the valvetrain it'll cost you a small fourtune. Even at 2klbs the car with 160whp is about as fast as a stock 350z vq35hr. The car was not ment to go fast in a straight line. It's just how it is, I'm going to do N/A mods and even that sould make a massive improvement through the turns.
Most people use the blitz supercharger because it's a clutch system so you can controll your boost, which allows you to get good gas mialage when need be. |
