Thinking about making a full Intake Manifold Replacement

[YogiYaris]

Well I was thinking of making a full intake replacement with a larger throttle body and larger ports. What do you guys think? Would anyone be interested in purchasing something like this I will dyno test it and use a wide band to keep the motor safe. Let me know I have seen exceptional gains from this before.

[spkrman]

duno how much the yaris can benefit from it in otherwise stock form... I can see it making a significant difference to a heavily modded motor though.

If you build it, and you get good results... people will be interested... and I'd say the turbo users would probably be most interested.

[turboyaris]

already have one in the works should be done within a couple of weeks I am hoping. However like spkrman said it is really only going to benefit the turbo users, long tuned runners are your best bet in a NA setup usually, a decent amount of research goes into figuring out the best intake manifold, therefore until you mod your yaris there wont be a need for a different style intake manifold. A company that escapes me at present tried a NA intake manifold for the Xb but it failed miserably. I believe they tried selling them for around 500$ and only gained 2 hp or something of the sort. I am very optimistic on my setup with the turbo and everything, I may try and see if there is a benefit on an NA setup so I will be looking for a guinea pig to maybe test this out and see. I am hoping for a ~20 hp gain outta the intake manifold and throttle body if not more with the turbo setup. Stay tuned and we shall soon know hopefully.

[turboyaris]

oh also... i wouldnt enlarge the ports too much on the intake manifold. reason being is then individuals will be required to port their heads as well. Leaving most people behind in this area. However if you do decide to continue I would leave enough material to have a slightly larger port match in case someone is porting their heads they can port match their intake manifold as well.

Basically sums up the difficulties of aspiration mods on the 1NZ. As long as the factory ECM is running the show, the Yaris has nothing. I can't wait to see all the weak ass arguements to that statement, but its the plain truth. Don't roll around thinking your intake and exhaust makes you fast in a Yaris. Its going to take a bit more than that.

Long runners are definitely a must, and as Nick said you have to leave room for head work to be done down the road. This would open up a whole new world. I could get that port job I always wanted and make it worth something... and grab a piggyback and dyno it and get a good tune and... oh...

Oh me god. I just messed me pants. :help:

[spkrman]

just go standalone :)

or wait until someone releases something to program the ECU in here.

[ChinoCharles]

Standalones come with features you don't necessarily need unless, say, you have a turbo under the hood. :wink:

[turboyaris]

standalones are retarded for our cars. too much extra crap run by the computer it would probably be mad gay to wire and make everything work again eventually. I think the piggybacks like the greddy emanage should be fine until you do some crazy racing setup. standalones are too much money for just a turbo kit.

What are you headbanging at... I'm going to smoke you without a turbo Mister Dubs. :eek: :laugh:

I'm gonna smoke the tires on the dubs and get a vid :headbang:

We'll race one day, and you'll get to see the sexy @$$ of my car the whole way... and I wont even have to bother shifting, heck, I could be using my right hand to grope the supermodel in my passenger seat.

[ChinoCharles]

I'll see your ass till I hit the gasssss... then I'll make the pass and you'll finish last... maybe if you got some nitrous you might stand an f'n chance...

I could write a song... don't test me. :laugh:

would be fun to have a 3 way race... turbo, n2o,
and stock. I'd say it could go either way, depending on how crazy that giggle gas gets you!

Turbo + nitrous is askin for it lol, I really dont think the trans would hold up to that much of a beating... although it may, we'll see down the line if I head that route :headbang:

This is going to sound bad... but for me the turbo is there more for show... although it will DEFINITELY get used, wow would i love to be able to pass people on the highway without planning 2 miles ahead...

either way my yaris poops on your yaris.

[ChinoCharles]

Haha, I'm just messing with you. I'd never write a song that bad... I don't think.

[heylookitsjames]

Some one should design a variable length runner setup, or maybe even just a simple 2-length setup triggered by the vvti engagment... like the schrick manifold for the vr6... longer runners to keep low-end port velocity high and then short, squat runners that open high up to support a higher volume of air when needed. Mazda used a similar design setup called VICS and even toyota had TVIS, so its a proven method to broaden the powerband.

[ChinoCharles]

TVIS came stock on the 3S and 4A motors I believe. You'll never see it for the 1NZ.

[YogiYaris]

Yeah I was definitely going to port the heads with the manifold I was just wondering if anyone was interested. It seems the interest is high so... I will update you guys probably in a month in a half or so. I want to get it to 120 whp. I am going with a cai from trd, porting the heads, intake manifold, greddy emanage (or something I haven't decided on this), underdrive pulley, full header back no cats, and a crazy awesome tune:thumbup: I don't know I will let you know later thanks for the response.

[Vic-2NZFE]

Emanage is over priced for what its going to do to your Yaris
it has been proof on 1NZ engines and the result :iono:
waste of time and money.

Good luck dude :thumbsup:

[turboyaris]

result for me was 182 whp and 184 ft lbs of torque original numbers on the base tune with the emanage was around 174 and 172 so yea it got 10 hp from the base tune to the final tune not to mention how crappy the car would run without the emanage. The regular emanage is only around 300$ so I don't see how it is expensive. Kenny also said that he was able to lean out the stock tune and the off boost tune, because the stock tune is fairly rich with the timing more towards fuel efficiency.

doooooooooo it! :thumbup:

Good numbers dude, i forgot to mention that the guy that started this thread is NA and not turbo and there the Y of my responce. I guess ill need to be more detailed when posting :redface:

regular emanage is only around 300$
Where did you get it so low??
lowest price i've seen is @ least $400.00 without shipping, $300.00 not a bad price

I feel that you have no experience with standalones & your statement will cause confusion. ANY standalone (AEM EMS, Motec, Haltech) will be 1000 times better than ANY piggy back. I guarantee you that you can get more power with a stanalone. And as for standalone being to much $ for just a turbo kit, when do you feel you should go with a standalone?

let me clarify then, so as not to mislead people. The majority of people on this forum have an NA and will always have an NA setup, even those that go turbo will more then likely stop at the 8-12 psi level. That being said if you have a stock engine with a turbo on it I don't see you getting much out of a stand alone system, certainly not for the amount of money and work to buy it install it and have it tuned. Yea sure they are 1000 times better but only when engine parameters change. I feel a standalone would be needed on a fully built engine, with adjustable boost levels, longer duration cams, bigger valves, these kind of components. If you look at a lot of the tuner cars, you tell me how many of those cars go stand alone. Very few, because of all the work associated with the setup. The majority of the other tuner cars like SRT4, evo, sti all of them go to a reflash or piggyback system.

Yep.

[turboyaris]

the main reason to switch to a standalone is when you start using sensors that the factory ecu can't handle. i.e. vein pressure instead of the normal MAF or MAP sensors and other situations like that. Until you have a fully built race car I would say your thousands of dollars would be better spent elsewhere.

I agree this point a stand alone on a NA setup is not worth the $

even those that go turbo will more then likely stop at the 8-12 psi level. That being said if you have a stock engine with a turbo on it I don't see you getting much out of a stand alone system,

Here is where I disagree. A piggyback system modify existing parameters that are in a ECU. It has limits, On a scale of 1-100 you can only adjust from 35-65. A stand alone allows the user to start from scratch. You can adjust from 1-100. You have full control of fuel & timing. You are not modifing an existing parameter.

certainly not for the amount of money and work to buy it install it and have it tuned.

This is the main reason most Yaris owner will never truly know the potential of the 1NZFE, you are tight in the wallet. That is the reason most Yaris owners bought a Yaris. Its a inexpensive car. Speed is determined on how much $ you are willing to spend correctly.

Yea sure they are 1000 times better but only when engine parameters change. I feel a standalone would be needed on a fully built engine, with adjustable boost levels, longer duration cams, bigger valves, these kind of components.

Pistons, rods, adjustable boost levels, bigger valve are not the reasons to go standalone. Full adjustability, safer, more reliable, faster processiing speed, On board data logging, knock control & it makes more power.

Mabey in Phili piggerbacks are mostly use but here in the MIA STI, SRT's & Evo's that are making real power are all using AEM EMS. No they do have an advantage, the AEM EMS replaces the factory computer completly.

These are good points.
I have a custom-wired MoTec in my fully-built Scion tC. I did that because the piggybacks didn't give me enough control, as noted above. Last tune netted me 443 whp, 474 torque -- not bad from a 2.4L street car. And more room to go even hotter.

But.... it was friggin' EXPENSIVE to do all that!!

I will never go that far with my Yaris motor....but I hope some people do.
