DIY - 1.8L 1ZZ-FE TB Connector Chip Swap - Page 2 - Toyota Yaris Forums

that's another possibility, but it would be interesting if you could look at the model number on yours, to test WolfWings' theory!

mikenacarato · 03-09-2009, 04:38 PM

on both cars the throttle bodies came from japan. there is no american built TB on either car. the chassis may be built here in the us but the parts may not be. i opened up my corolla tb and my yaris tb and both are made by denso japan.

Yaris T-Sport · 03-09-2009, 04:45 PM

car is running great with the new tb set up, no cels what so ever at this point

REALLY, toyota parts catalog lists 2 different TB's for corolla/matrix based on vin numbers. my findings were already posted.......

Where do you see your gains? Low end? Top end?

Gains are reported to be in the mid- to high-end of the spectrum. I still have to install it to see for myself.

whooppee777 · 03-09-2009, 09:10 PM

wait wait wait.

people with the 1zz tb were getting cel's? i never got one. i did get some oscilation but only in temperatures below freezing.

could u swap the chips from the yaris 1nz to a scion tc tb? because i noticed a greater gain in power and response using the tc TB except i got thee CEL from it.

yarstar · 03-09-2009, 09:55 PM

Whooppee - you just got lucky. The rest of us had major CELs issues. Mine came on no matter what I did.

The gains seen with mine was major pickup mid to high end. The car really jumped @ 40 mph and continued excelerating from that point on, much stronger than stock.

Drilling out these rivets is a pain, but I'm working on it. I see you also used a allen key bolt so you keep the bolthead size to a minimum. There's one spot of the six that is super close fitting for an 'other than rivet' attachment.

whooppee777 · 03-09-2009, 10:06 PM

i'd rather b lucky than good.

im thinking about taking apart my tc throttle body. it sounds like something is loose inside of it. could something b broken inside of it? the 1nz throttle body sounds solid when u shake it, no noises or feelings of movement from the inside

mikenacarato · 03-09-2009, 05:06 PM

ok so you found 2 part numbers..good job. my yaris throttle body pn is different than the 08s, was my car made in the usa? i dont think so. denso japan is made in japan.

Mine must be uber special ;)

mikenacarato · 03-09-2009, 05:41 PM

please feel free to explain it to me, ill listen. you said american made throttle body. the throttle body on that car is not made in america. the chassis and body panels are, but electrical and most engine components are still made in japan. go look at the sticker on a new camry or corolla and it says the percentages and what was made where. if they dont have that sticker on it, then ask them and they will go get it

hatchbackkid82 · 03-11-2009, 04:28 PM

See post #19, this thread.

Thanks just bought one from the same guy

How much bigger is the new throttle body opening than the intake it bolts to, as the intake side may become the restrictor? From the picture it looks like it has a step so you can't really port match it to the new throttle body.

I'm very sure you can, the other memeber has an TRD intake and he has been running with the new tb.

the pic of the my OEM tube has already been ported .25" bigger

1nz = 2"

1zz = 2.25"

just a report back it's been 11 days since ,my chip swap, cold start idle is around 2000 RPM instead of 3000 before, drops down to around 1000 in a couple of mins, when the car is fully warmed up, it idles at 750 RPM, no CEL the whole time, very happy with the extra mid-nigh end gain, can definitely feel the difference by my butt dyno even off the line, much better mod than an intake or exhaust if you can find one cheap, perhaps I couldn't even feel a difference when I upgraded my intake nor exhaust alone by my but dyno expect the increase of engine noise, but this one, I surely CAN.
