building my yaris for backroads driving because there is no track close to where I live. Using these videos really helps when deciding on what mods to do as well as what to do when installing specific mods. Thank you Joey!!
Cheers bro doing the same with a 2zr rolla.
Hey man, I am building my 2008 yaris S for back roads also.... I just put 15" Sparco wheels (15lbs each) and Nitto Tires (Neo Gen) Small wheels work really well and the tires are insane grip. BC racing coilovers with cusco underbody and strut bracing as well next week. Upgraded rotors and pads new control arms and bushings all next week. Once the breaking and handling is sorted it's on to power.... I will follow you!
I agree im thinking to do just the xd fuel injector an if needed the fuel pump too cause i would like just a bit of more happiness, im currently running cold intake,headers, weapon r manifold an open exhaust i still running a muffler open flow it works great no problems
had my yaris for a year just now looking at upgrades thanks! still learning hear
The Scion xD's fuel pressure regulator delivers 46psi, while the Yaris gives 44psi. So you've definitely increased your fuel delivery. While you were at it, did you peek if the mid pipe of the Scion xD was intact? it's fits the Yaris, and it's slightly bigger diameter. Also, check if the VVT solenoid has this PN#15330-21020, which was supposedly from the Vitz RS, which also supposedly engages VVT at 2500rpm instead of 4000rpm.
Someone read my post! But it doesnt't engage it at a lower rpm from what we can tell its just allows for faster vvti response.
The VVT solenoid on the ZR engine is different to the NZ engines. I ran the VVT solenoid number in the system and couldn't find anything. I used my car chassis number 2008 Vitz RS and the numbers I got are 15330-21011 and substitute 15330-21010. You can try finding those.
@@kimoliburd8829 15330-21020 is the OEM correct unit, the aftermarket ones work but are not the performance variant. I have the RS one in my car, VVTI feels like it comes in stronger. It just allows for higher oil flow, which decreases vvti asctuation time.
Rooting for you and the pandayaris!
ASE certified master mechanic also fellow Yaris racer also been racing with the SCCA for 10 ish years now ... Replacing fuel parts like injectors and pumps that's have more flow rate .. WITHOUT PROPER tuning of the ECU is probably doing more harm then good u need a proper Wide band sensor and a tuner to see any or little benefit from this mods I would stick to OEM parts cus it's probably running too rich stock anyways and u might be making it more rich
Thanks for the insight. The fuel pump needed replacing either way. With the intake, throttle body, the car was occasionally giving lean condition codes. The ECU tune helped with that, but since the rev limit has also been raised, this pump is more piece of mind than an actual gain.
Hey guys I'm doing track days in a Yaris in Australia. What are you guys doing about baffled sumps? I've done a handful of track days so far and seems to be alrite on the standard sump, but just been thinking if I should do something to avoid starving the engine of oil
What kind of side band sensor and tuner do you recommend for the Yaris I want to mod my daily driver yaris but the proper way so it doesn’t totally ruin reliability
You really need an aftermarket ecu to tune it well.. haltech or link
Hilarious when people call themselves master mechanics
Went with the NGK iridium spark plugs on my Yaris. Ive been using them for 1 year with no issue.
I'll have to watch the video for the xD throttle body, but I did similar with the Echo with a 2000-ish Corolla 1ZZ-FE throttle body swap. Our older 1NZ's usually call for making our own sandwich plate and gasket to fill in the gaps from slightly different plumbing, but another thing you should consider is simply boring out the opening on your manifold a little bit.
The Echo, xA, and xB1 all suffer from having an oddly shaped gasket because of an idle-air passage off to the side. The Yaris is just one bore, which looks like it can be Dremel'd out to really help that xD/Corolla throttle body work to your advantage better, especially since your ECU is more flexible (Echoes received absolutely jack in North America... Scion OEM+ is the best we can do). Speaking of which, have you considered looking into Yaris SE parts that changed, like the tighter steering rack? Not sure the torsion beam was any different, and the SE interior and suspension (maybe rear brakes) are irrelevant since you're already upgraded there.
Back to intake stuff: I'm back to a stock throttle body right now since the 1ZZ idle control valve went on the fritz, and it really doesn't have the pull it did (running a full length AEM xB CAI and 4-2-1 header, and Magnaflow weld-in cat... seeing my fuel cut off consistently around 6,700 or so), so it does make a difference even for the nanny ECU.
Having some spare 1NZ manifolds from the Yaris and Scion designs (and a 1ZZ-FED Celica), the Yaris has a different plenum that seems smoother, more open (more like the Celica). I still need to find a cable operated four-bolt Toyota throttle body that would work on a Yaris, but haven't taken the time at Pick-n-Pull to find one, but would love to see how much more freely it can breath with a Yaris mani.
Looks like the spacer you had was for a 1ZZ-FED engine from a ZZW-30. It’s different to the 1ZZ-FE one. The FED has larger valves (1mm) and makes about 12 more bhp. It’s in the Celica and MR-S. I found all this out when I put an FED head on an Elise S2 S (1ZZ 134bhp). This engine is about 127 in a Corolla and a bit more in the Lotus but still less than the Celica/MR (about 140).
ahh, that makes a lot of sense
Lets goooooo!
Hi! Did you think about ZR engine swap? I was reading a lot of articles from USA about swap ZR to Yaris, it looks very easy if you'll find a Scion XB
Denso sk20 is my choise
did you eventually find another adapter for the 1ZZ TB?
Will you ever run the Yaris in the 1/4 mile? I’d love to know the ET
I have 1nz toyota vios ncp150 200hp for drag race
Where did u get the adapter plate
Where can I get the throttle body adapter ?
Also a bigger throttle body does NOTHING if the hole in the intake manifold is small / tiny behind the throttle body so either port match your throttle body or put the OEM one on for the idle and better driveability I'm general .. I have a 2zr throttle body on my car but I did port the manifold to match it required alot of cutting sanding drilling and Epoxy in so places
I also have a 2zr throttle with the manifold ported to the throttle. I used the 1nz throttle body control and mounted it on the 2zr throttle body. Idle is perfect and it doesn't have the rev hang like the 2zr throttle.
I'm looking to do this currently. Did you remove that that copper mesh thing on the top half of the intake behind the throttle body?
I don't think so, because if you put the larger TB it is going to allow more air at the same angle as the smaller TB. The hole in the intake manifold would be the bottleneck only when you get close to WOT.
could use the 1zz injectors as well
Have you taken it to a dyno yet?
I always check the gap regardless of whether the plug is pre-gapped or not. Are you able to tune the ECU? It seems at this point, you're better off financially to buy the Xd, swap over engine, harness, ECU. And it would have stock reliability, but more power
The ECU has a tune from Chris Taylor Racing who has tuned a lot of the B-spec Yaris competitors.
I have a question. Is the yaris engine replaced with 3ZR-fe? 2.0+6mt can do it? Thank you!
I've always worried the 1zz TB would cause the 1nz to run lean, is there a way to solve that issue without some kind of ECU work?
Que cluster del sedan ???
Heyy I didn't understand it very good: does Celica GT's sparks plugs fit in the 1NZ-FE?
I'm looking to get this as my first car. Where did you get the headlights from?
amazon. Spec D. a bit of a pain to wire up though
@@RassoolRacing Would the 2009s fit a 2011 Yaris? I don't know if they used slightly different headlights since it was facelifted.
Did you change the guts from the 1nz-fe throttle body into the new larger throttle body? It will not stop throwing errors if you left the 1zz guts in. Drill out the rivets, pop in the 1nz-fe circuit board into the 1zz-fe throttle body and it will fix the error codes. I still am yet to do the throttle body as i want to have a adaptor plate machined first so its perfect fit.
1zz guts. No errors for me
@@RassoolRacing Fair enough, easy fix in the future if they pop up. Been waiting to find a cheapish 1zz unit to do the swap myself, but read everything I could find on the yarisworld forums on it. Some people seemed to get the codes and some didn't, might be to do with what ever guts your throttle body had in it to begin with.
Iknow people use toyota Celica 1zz intake manifold to
What does the ‘colder’ spark plugs do in terms of performance in comparison to the spark plugs meant for the car?
im trying to find out. although majority against changing it
JDM Vitz RS vvti solenoid next and depending on your factory units a "c" marked maf unit and RS coil packs. No point with irdium on a yaris, the plugs are easy to get to and copper provide a better spark but with more maitenance, you can clean them every race tho and get 5 or 6 brand new sets of ngk coppers in same rating for the price of the iridiums. I just clean mine every service and every 3 she gets new NGK coppers and she purrs. Ive been making posts on yarisworld, theres lots of good info there for our cars.
The 1st Gen JDM Vitz RS is what you mean for coilpacks. The 2nd gen uses rocker arms and has a wider valve cover with long reach spark plugs like those in the 2TRFE Tacoma and longer coil packs than the 1st Gen Vitz. I had both generations vitz
@@kimoliburd8829 No 2nd gen RS has higher amperage coil packs compared to a non RS 1nz-fe (but some countries got the higher amperage coils as standard anyway some didn't) I have a mark2 no idea about mark 1.
@@vctrsone I can twist my logic on how vvti solenoid,coil may give some gain. But how does maf sensor a/b/c type give anything?
@@AmirFauzi666 The Thai guys insist on it if tuning the 1nz-fe. I don't speak enough thai to get on their forums, but I heave read posts where other people who could followed the build logs and that was one parts of it along with the RS vvti Solenoid and RS coils.
@@vctrsone Funny enough we Malaysian also learn to modify from the Thai people. But here mostly use k20 coil packs. I dont condemn tho, just trying to get more input. Cheers
Hey Joey, fellow Yaris RUclipsr here. I wanted to find out if you had any feedback on the Cusco Center-Lock Pillowball Upper Mount Set yet? I'm looking into buying a set and just want to know if they are worth the money? Thank you!
So far, they are definitely worth it. The Yaris I drove in lemons also had them.
Ive never been able to make the 1ZZ throttle body play nice with my 2014 Yaris, it always idles erratically or rev hangs for multiple seconds at a time.
My 2014 runs correctly with some throttle position sensor tune up, the srcrew behind the epoxy is your solution. Plug in a obd2 reader and check for data stream *absolute trottle position* needs to be at 15.3%
Get a mitsubishi colt czt model it to 200 plus bhp.
Can these upgrade work for 1KR-FE ?
Question for All. I wonder if I can lift 1.5 to 2 inches with oem parts from other cars.
Scion xd suspension fits apparently. I've heard that's a small lift
Omg the more I watch this video sigh SPARK PLUS have to be the correct heat range and Iridium as actually has a weaker spark for less power then a cheapo Copper one .. the only thing iridium does is last Much much Longer that's why OEM use them so they don't have to replace them for 100k or so but if u want a cleaner hotter spark a 2 dollar OEM plug would be better ... And make sure it's the correct heat range for the tune
Scion is called ist in japan
Why’d 10:30 sound like a BOV haha
Cus 3rd crunches :(
u need tune then you need more fuel
Does this pass smog? Lol
👀👀👀
What car is the 1zz?
You need 2zzge ASAP will never look back trust me
Brother what type of mount and other modifications am I looking at for 2zz swap. Please guide
Lol nothing makes Yaris faster. Worst car ever made.
