Lets make a Yaris Real Fast.....

[yaris2010RS]

the rating on the block i got from toyota, maybe its just their recomandation but i dont understand y they would low ball it. i have no idea, i dont race any cars on a track or professionally. i've seen engines fail and i have also seen blocks fail. it usually has more to do with lack of care and maintanance then too much HP. as i said in my post also, i am under the influence the rating is on the block itslef not internal parts. if you decided to put turbo, nitro, and what ever other riced out shit you could think of without rebuilding the entire motor your gonna be into problems. and i dont know about your GN but the regal has a 3.8 v6 auto tranny is rated with stock motor and tranny not to go in "over excess"(over excess is the exact wording that i was told) of the block rating of 340ish (i dont exactly remember if it was low or high 340's)

so after saying that, let me rephrase my statement, the engine rating of the yaris stock 1.5L is 168HP, over that without a complete engine project will definatly give you a new engine project.

Really?

the rating on the block i got from toyota
Toyota directly, like you called Toyota & spoke to a customer service rep?
A Toyota salesman?
A Toyota mechanic?
the rating is on the block itslef not internal parts
Again I dont know where you are getting this info from, but the block is the least of you worries, you will break a rod or piston way befor the block
if you decided to put turbo, nitro, and what ever other riced out shit
American cars also use turbos & N20, are they ricers also?
without rebuilding the entire motor your gonna be into problems
Why? Why cant you boost an engine 5lbs and drive it like it was not boosted
and i dont know about your GN but the regal has a 3.8 v6 auto tranny is rated with stock motor and tranny not to go in "over excess"(over excess is the exact wording that i was told) of the block rating of 340ish (i dont exactly remember if it was low or high 340's)
FYI, a GN is a Regal with a turbo 3.8 V6
so after saying that, let me rephrase my statement, the engine rating of the yaris stock 1.5L is 168HP
Sorry but that is not a fact, that is speculation. Please try not to spread incorrect information. There are enough confused members here already.

What an idiotic statement. The things you listed are actually the complete opposite of "RICE."

Race Inspired Cosmetic Enhancements.......

So turbo diesel trucks are riced out?

[RacerFreakXXX]

IDK why anyone is worrying about the block or anything like that. If he isn't gonna build the engine and wants to push the limit I'd assume he'd want to do under 180whp. The question is how much is just right. I'm assuming about 160-170 would be the max and is plenty fast enough.

A turbo is "riced out shit"? -- you just lost 100% of my respect right there, sir.

[RacerFreakXXX]

OUCH! you know you crossed the line when you piss Garm off.

[Nexus1155]

Damn then apparently my Audi has twice the amount of rice :-/

[Saskatchewan17]

So it looks like you can't really push the stock block much past 150 WHP without problems with the internals.
12 second Yaris? Not gonna happen unless you have a built engine/turbo, stripped interior, and drag slicks. Even then... I don't know. Launching a FWD car is tricky stuff. I know you can't break into the 12s in an MS3 unless you are fully bolted on and a fantastic driver... or have slicks.
Also, when do you have to up the injector size on the Yaris, and when do you run into fuel pump problems? How much possible WHP can you make on an NA motor?

i'm sorry, but a yaris with a turbo for everyday driving is riced out. my definition of riced out is un needed upgrades not gonna lie, i didn't know there was an actual deffinition. some cars come with a turbo, they are designed to work with a turbo but we are not talking about trucks or other cars, this is about a yaris. for me, work and back, school and back, a turbo on a yaris is a waste, if your gonna race, okay, put a turbo in. it all depends what you plan on doing. yes this is fourm is talking about making a yaris 12 seconds but without total engine mod it can not handle anymore then (i'll even stretch the limit) 200HP, it will blow up. since everyone has a smart ass remark, how else would you get a stock 1.5 L to over 168 HP without rebuilding it and modding it? and as i said before i have no idea what the block 168HP rating is, maybe its the ideal running HP everyone should get their car to, i simply stated there is a rating of 168 HP on the block, take it, do what you want with it. and without lots and lots of engine mods, you will never get a 1.5L over 200HP. driving a yaris with 200HP we are gonna have to send a search party for you on the moon. as i say over and over, revise it a little more at a time, the engine conponents are rated to 168HP, yes you could get away with 170, maybe even 180, after that, toyota has nothing to do with the failure of the engine. if you want to keep it from failure, rebuild the entire thing. yes you can put w.e mods you want and drive like they are not there but whats the point? really it all comes down to you, its your car, your money, the fourms are about sharing knowledge and trying to help out.

you are just blowing smoke. why dont you take the time to read most of the previous posts on the engine builds that people have done with the STOCK block on here.

there is more than one member that has the stock block over 200 tuned.

and its nitrous, not nitro. lol

yaris2010RS: i'm sorry, but a yaris with a turbo for everyday driving is riced out. my definition of riced out is un needed upgrades not gonna lie, i didn't know there was an actual deffinition
Did you find this "actual definition" in a websters dictionary?


this is about a yaris. for me, work and back, school and back, a turbo on a yaris is a waste
This is the same thing that was said 10yrs ago about Hondas & how wrong the ignorant were


without total engine mod it can not handle anymore then (i'll even stretch the limit) 200HP, it will blow up
Upgrading the pistons & rods ONLY will let you go over 200hp with out a problem with a turbo kit

since everyone has a smart ass remark, how else would you get a stock 1.5 L to over 168 HP without rebuilding it and modding it?
A stock 1NZ with a turbo kit on 6-8lbs will make 168hp all day long


and without lots and lots of engine mods, you will never get a 1.5L over 200HP.
Sorry but your completly wrong, A good turbo kit, pistons, rods & a AEM FIC or Emanage is all you need

driving a yaris with 200HP we are gonna have to send a search party for you on the moon
the search is over, come to Miami Florida

the engine conponents are rated to 168HP, yes you could get away with 170, maybe even 180, after that, toyota has nothing to do with the failure of the engine
Once you turbo, supercharge, N2O or change the internals Toyota voids the warrenty, the power is not the determening factor

[yaris2010RS]

i am completly down with making a yaris real fast, but most of the stock engine parts will not take the super HP, pray as much as you like, its not changing anytihng about the engine

[Brad D]

its more about the tune i bet with most of the engine failures you guys are seeing. with a good tune i bet this motor could see over 200whp all day long.

[Brad D]

Every motor people think has a set limit untill someone pushes it.. Same thing happened with the KA-t.. people thought it would not hold past 300whp.. now guys have hit 500.. the 350Z people thought you would need a sleaved block to make any real power.. now people make 1000whp with a stock block with forged pistons and rods...

here is a civic with a non v-tech B18 that we pulled out of the junk yard.. build up a turbo kit and gave it a good tune, we ran the car and draged raced it for two years. one day we got gready and added more power.. the tunner said "today is the day its going to blow" and yep on the dyon we overpowered the cylinder wall.. but guess what the pistons were fine.. you could of reused them.... this was at 375ft.lbs.. that is the limit for that block stock.


here is a a vid, we got it down to 11.1 on a stock motor... never opened up

Tamango took off his turbo kit awhile ago; thus why it's a NA xA.

My blitz kit made 140whp with 135 tq before i put on a custom overdrive crank pulley which added a couple more lbs of boost and made me at 136whp/140 tq. This was done in Hawaii weather on a dynojet. However, I am going to retune with the ultimate and tune accordingly for more power. I'm also installing a meth/water injection kit; and i have 1zz injectors and run 11-12 AFR at WOT. Nothing lean going on over here.

In your mind it should.

good upgrades. The overdrive pulley is a cool idea im glad somebody made it!
WMI will give you good results.

And yeah, it is my opinion about the racing. But I can voice it right? Don't place me as the bad guy because I believe something. I just would like to see 1.5's beat up on Evos and such on the track. Performance parts are developed for a performance enviornment. But anyone can enjoy extra performance anywhere it's all good. It's much more enjoyable on the track tho as I discovered.

136whp on a dynojet sounds about right. A typical Dynojet reads about 12% higher than our dyno. So that's about 119.

Well we wouldn't really know unless i dynod the same day/same time on a dynojet, then your guy's dyno. However, I know what you are saying.

And most people on here who have dyno'd their blitz kit have not even reached 133whp. So you suggesting that 136whp and what i previously hit before the pulley (140whp) is common for the blitz, I don't think it is. Atleast from the evidence shown so far.

ps: I just got the meth kit installed and running.

I know about that yaris; however, i remember reading somewhere about a yaris using nitrous that was in the low 14s or maybe even 13s? There was definately one in the states that I believe was in the 14s with just nitrous. He ended up blowing his engine on the strip. He posted a video of it somewhere on this site. He didn't want to say how he had the nitrous set up...
