dyno results are in!!!!

[forpinks]

DID SOMEONE SAY THAT THIS TURBO KIT WILL BOOST YOUR FUEL ECONOMY?

IF SO.... IM ON MY WAY TO THE BANK!!!

Will this be cheaper on group buy? and you guys at ZPI should sell an -
"install kit only" without a Turbo with it... just suggesting so that more people would buy it because they can get a used turbo from their EVO buddies for a price of a Nintendo Wii!!!

[ZPIracing]

Ok guys I just read thru a lot of this so I will try to answer as many questions as I can if I miss one let me know.

Reliability:

A turbo car is as reliable as the tune, we have turbo tC with over 60k on it and our personal turbo xb with 40k of pure hell put through it these cars are on stock engines and our in perfect running order. If a car is tuned well with a well designed kit the car should last a very long time with an aftermarket turbo kit. I know we have all heard horror stories and I am sure the Yaris world will be no different. Just remember that it is what you make it, if you can’t afford to play then don’t.

You should only turbo the car when you have the ability to buy all the parts that are needed to make it run correctly. Most of this is included in the kit but you get the idea.

Performance

Our Yaris kits add roughly 100whp to mix; this will make for an exceptionally fast car taking in to consideration the weight. Low 14 high 13 ¼ passes are a reality with tires and a good driver.

This kit you will see some lag below 3k this is very minimal and the car accelerates so fast that you are not here for very long.

This kit will come on .6 bar roughly 6.5-7psi. This kit will add 2-5mpg to your already unreal gas mileage when driven in off boost settings (highway)

Price & availability

We will have these kits in stock at the end of next week. We have not decided on pricing yet but you can expect it to be in the 3-4k range. This will be a bolt on kit including everything needed to install and operate this kit. This is not like some of the other kits on the market that do not include fuel tuning components.

Stays tuned to ZPIracing.net for updates and let us know if you have any other questions. I am sure there are 100 grammatical errors in this post I am sorry it is late and I suck at English.

Nice. Do you see those boost levels as the max...or rather the most you feel comfortable with going to for reliability?

Indeed...I think I called that 1/4 time. I would imagine that you'd rather use a wider street tire, DR or slick to get those 13 second times. The stock tires are NOT the first tire I'd choose to go racing with.

Strip the yaris down do some good suspension work like coilovers, sways, struts and some chassis braces underneath you could have a fun little SCCA car. As for the 1/4 mile...I guarantee you could probably sucker some rube into a few bucks by beating him in his civic SI or by beating the spread on estimates of your 1/4 mile time!

What ZPI said is absolutely TRUE! "if you can’t afford to play then don’t"! I have seen SO many kids crying about thier cars breaking when they push them hard. Be prepared for circumstances that are unforseen.

This is EXACLTY why you won't see me touching the engine of my Yaris. Not that I can't afford it, rather I DON'T want to. On the other hand, the stereo system and the vehicle's electrical system are my domain. I'm in full control there.

Bottom line guys, keep ahead of what you're doing, don't let Mr. Murphy kick you in your a$$! Let's see some more.

Dammit still need to save up a few months to get myself some turbine action... and then...

ZPI guys, a couple of questions if I may, and this might be of interest to others too.

I've been going through your site and looking at the stuff you have for the xA/xB, and I'm quite interested in the potential with the low compression pistons and a turbo kit. What kind of gains have you guys managed with this combination? And what about with the Stage 1 head?

[nester]

The rods and pistons would allow you to run more boost, and make more power safely.

[jdubau55]

Im not sure how strong the other internals are BUT once you go with low comp pistons you better start building the bottom end all together. I would say the thing to do is find you a wrecked Yaris and rape the motor out of it for cheap. Build that thing up in a spare room of your house over the winter. Then swap it in come spring.

I had some questions. For someone who has never installed a turbo but has more than enough experience on cars(ive removed power steering pumps, water pumps, alternators, starters, swapped stock exhaust manifolds with headers, tons of wiring experience)how hard is the install? How long does it take? full day? weekend? can all this be done without removing tons of parts from the car? im sure removing the wiper blades, trim, wiper motor and that big sheet metal piece would make the install tons easier.....

It looked like a 5 speed in the dyno video, what are your thoughts on the auto? any things to worry about?

yeah, it blowing to pieces. Can you imagine a econocar auto running 200hp when it was built economicall for 100? Not pretty. Besides, unless you're running 1000hp Supras or muscle cars, turboing a auto is lame....well, about as lame as auto cars in the first place.

lol dude come drive a 5 speed in la and see how long til you get tired of it.

and my question was how strong is the auto tranny, less or more than the 5 speed? they were both built for a 100hp engine so whats your point in that?

id appreciate someone actually answering some of my questions. thanks guys

The install is not really that hard. The kit will include all the piping, bolts, nuts, clamps, etc. I would imagine the install would be an all day affair in the garage, but you might split it up over a weekend.

We put the turbo on from the bottom/side of the car, by removing the passeneger side wheel and sliding the axle out.. Which sounds worse than it might be.

Wiring is ~12 wires, only one of which has to be cut. The rest are splices.

If the automatic stayed the same between the xB and the Yaris, I wouldn't expect any problems. We've installed about 5 xB kits on autos and they run great. You can install a tranny cooler for added safety, and we'll be releasing a valve body upgrade in the next couple weeks. An upgraded torque converter is also a real reality, if we get enough interest.

To the person who suggested a no-turbo kit, the evo has a different flange than a typical mitsu. The cost difference between a kit with no turbo and a regular kit would be about $400.

[sqcomp]

If you're going to do pistons, you might as well ceramic coat them along with coating and replacing the valves and valve springs. Anyone done a head and cams for this little engine...is there a windage tray kit for this engine? Heck, go hardcore and do a 5 angle jobbie on the head.

[turboyaris]

Sorry I haven't been getting back to you guys.. I have been really busy and am kinda on vacation but I will try to be on to post some messages here and there.... Alright here goes the final dyno results we made 182 whp and 184 ft lbs of torque. As was already iterated the tune is safe we ran between a 11.2 and 11.6 for AFR which is safe and would keep you from blowing up your engine. The wastegate is controlled by the internal spring and is not adjustable by the owner unless you were to install a boost controller.
Yes you will get better fuel economy because Kenny was able to lean out the stock map in a safe way. I received about a 3-5 mpg increase in my drive down to Florida so it definatly gets better mileage.
As far as the stock auto tranny is concerned I am almost certain Zpi has done their turbo kit on the xb in an auto before but that would be easily solved by a quick call to them on monday but i am willing to bet that I remember hearing that. If not they deal with a guy that can make you upgraded valve bodies should you decide to increase your power levels beyond that.

As far as selling just the kit minus the turbo, it would be silly the turbo isnt that expensive to begin with, so then buying an old one off of a mitsubishi is a risky move as its seals could easily be bad, plus why be cheap about it. If you are going to buy a turbo kit for a brand new car wouldnt you want everything to be brand new just seems logical to me.
You can possibly run more boost on the stock engine they have had their XBs running 12 psi without a problem, on slicks at the track they did however snap an axle with that setup. So yes it is possible they just don't want to sell a kit for 12 psi because they aren't sure how long the engine can last at those levels. The more you boost the more a stock engine gets fatigued so that boost level was chosen to keep it safe and reliable.
Their is plenty you could do if you wanted to do a full engine build, it is more possible then you think as most of the parts are available to do a full build they just require some research and maybe a couple one off parts.
Thats about all i can come up with for now. If there are more questions fire away or pm me or whatever.

What what just said is VERY important.

When you guys buy this kit, keep it at it's predetermined level. As I'm reading, there are several options to raise boost level. The thing I'm reading that scares me is the Xb's axles *BREAKING* with slicks at 12 lbs.

This means that the vehicles they're going on ARE NOT DESIGNED for the increase in tourque and horsepower. I've heard of axles breaking on my old SRT at 450+ horsepower. I'm not trying to be a downer, I'm just saying BE CAREFUL with your investment.

It might not be a bad investment to send your tranny out to a place like Perfomance Autowerks to rework your internals. Is there a compny that offers beefier axles for the Yaris?

Remember, your vehicle is going to be ONLY as good as it's weakest point. As ZPI has said, you need to pay to play.

You can't compare a yaris to a SRT4, really.. Well, I guess you can.. SRT-4 comes out of the box with about 200-220hp.. You double that to 440, and you break axles..

xB comes out of the box with about 90hp, you increase that to 200hp, you break an axle when you accidently dump the clutch on slicks.

There are axles for the xB/xA. I don't know if they are bolt in for the Yaris.. Rated for 500hp, so I've heard.. :)

[nester]

I also think more importantly than talking about the dyno numbers is how the car drives..

The car is a quick little booger... and with the stock hubcaps and the intercooler tucked away, it's a sleeper for sho.

One, if they were so inclined, could put a 5psi spring in there, with a AEM tru-boost, drive around on 5psi all the time, and then turn it up to 8psi when they're feeling froggy.

[sqcomp]

Double that HP over what the car was designed to do...

Could this be an add on option? I think 5psi would be more than enough for everyday driving in this car. How well will the stock map work outside stock boost levels?
