Who said Yaris was slow?

What's your boost level? I'd wish for lower boost levels BUT having seen N/A conversions, I'd imagine we're talking 10-14 lbs?
The pulley replacement is a logical thing. I like that. Doing anything with the stock motor mounts? Not being a supercharging guy, how does the idea of a larger (bored out) throttle body and polished instake manifold sound? Make it smooooooooth. The meth injection might be a smart thing. Might look at a crank scraper and a fuel return line. I'm not overly familiar with the Yaris engine. Actually I need to stay away from it...I'll get myself into trouble. I'll just stick with stereos and my friend's turbos. Just BE CAREFUL! I hate hearing about engines self-destructing. Keep that boost manageable.

What did the car baseline on that dyno?
It definately sounds good. What are you using for engine managment? Have you adjusted timing yet? Ashley |

There is not going to be any "lag" in a traditional sence, but it will just pick up on the top end since tha car has high compression and is really an NA car. The question is when does the car achive full boost? Put it in 4th at 35 MPH or so, hit WOT and tell us at what RPM the car hits full boost, and what that boost # is. There is no need for twin turbos on this car. All you need is a properly sized turbo and you will hit full boost under 3000 RPM and hold it to redline. Ashley |

Obviously there's not going to be any lag...it's a S/C. I was just floating the idea of a TT setup on a DOHC vehicle. I might agree with you about the "no need" for TTs on this vehicle. Technically since the engine isn't engineered for speed and power, there's no need for a S/C either. The top end power won't be there like it would from a turbo but still, it is there. This is why looking at the numbers and graphs would help us make decisions.
The TT argument could go on for a while. When you say "proper sized turbo" you mean what will give the mean performance. The middle ground of boost lag and overall boost pressure. Hell, there's no need for a TT setup on a Supra, a 300z, a WRX or EVO...but they're out there. An example is the SRT, give a good manifold with twin stockers and you have just as much output as a big "laggy" turbo with faster spool. Port and clip those babys and you're going to be screaming. Tell me the sound alone wouldn't give a chub or two! On the other hand, they made that 2.4L for a turbo application. DCR is working with at least 500 Hp on the twin Mitsu stockers at a faster spool than a GT30 or GT35. I like the open ended discussion though. Please, don't get the idea that I'm trying to shoot it down. Having seen heads blow from too much boost...I just want you guys to BE CAREFUL!!!

What is important here is that as more and more people do get this, that will lead to more and more people taking notice and making more and better parts for the Yaris. I see this turbo app now where is the guy going with the NA build. Id love to see be able to have my Yaris scream up to about a 10k rpm redline. Someone need to hook up with JUN or Top Secret and have them tune the Yaris. Awesome results btw.

Get AEM to do the EMS for the Yaris and you'll have 10K ability. You'll have to re-work the entire engine though from top to bottom...
I agree with the tuning idea. Demand is the mother of invention!

Or convert to a cable throttle, which is still no picnic.. Wiring nightmare. I also don't think you're going to be spinning a stock motor to 10k. Been there, done that, got the t-shirt.. or something..

Boost is between 7.5psi and 8psi. Nothing on the motor mounts. Can't port the manifold, it's plastic.. Throttle body, maybe, but it has a lot of ($$$) electronics in it.. Return style fuel system is only needed if you want to be able to bump the fuel pressure from stock, which is not really needed at this power level with these injectors.. The stock pump and fuel lines will flow fine at this level.

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?
