No, you will still have increased throttle response. You just won't see the full benefit without supporting mods.

Hey just wondering if anyone has figured out what the stock air box cfm is, I know that the 1nz-fe flows about 170 cfm and the TB flows about 250? cfm, so if free flowing NA we are hurting our engine performance (noticed this as I accelerate better at about 3/4 throttle) anyone else look into this?

The one I picked up is from an older celica from the late 90's, drive by cable and 3 stud mount for the TB. ports to the head match 100% however the bolt pattern doesn't. I just need to find time to go at my friends home machine shop, machine a new plate for both the TB and to mount on the head. Then cut and weld them, polish up the intake with a clear coat for a finish. I'll have time in a few weeks. The air intake I purchased a 45deg. 3" tube, tig welded a tube and machined maf mount then installed a K&N cone filter. I still have to finish my carbon fiber air box and tubing to take in cold air below the headlight somehow. This winter if budget allows it, the head comes off for a port polish and possibly cams. It's all about money and I have three cars that are not or will not be stock. lol

I'm thinking about doing this mod next spring to go along with my intake and header.

Rock auto only has the 031 TB listed. Will this one still work as long as you swap the chip from th stock TB?

Does anyone know an online source to find the 030 TB?

I will have to keep running the coolant to the TB due to where I live. Has anyone been able to run th stock hoses by just swapping them a previously stated?

[scod4025]

About the hoses it's not hard to get a new piece of hose got one from auto zone cut to the length I needed for like 4 dollars

I couldn't find anywhere online that sold the TB but searched for toyota recyclers online near me and found quite a few that had them and cheaper then getting it though the auto parts stores

Thanks for the heads up. I'll likely buy extra hose just in case.

Did you give th recyclers the parts # for the TB and ask I they had it?

[scod4025]

I just asked for the year and model that you want the TB from mine was from a 2006 corolla

Hello Black_griffin6,

Quick question, do you happen to have a part number for that 1zz throttle body? I'm looking to install into my '09 Yaris hatchback, to complement my other mods (K&N cold air intake, Blitz supercharger, DC header, Magnaflow catalytic converter, and TRD exhaust).

Thanks!

I do actually! The part number is 22030-0D030.

There's actually one for sale on ebay right here.

Do you plan to port your intake manifold? The stock TB gasket won't stay put or seal with the 1ZZ body, if I recall correctly.

If I recall correctly, it worked find for me. I just used some silicone gasket maker around the new throttle body just to ensure an airtight seal.
I might have did away with the stock TB gasket...this was a few years ago, I don't recall exactly. XD

If you can find one at pull a part then that's the more desirable route.
My local pull a part doesn't have anything newer in it usually.

[NJP440]

Ah ok my local Pull A Part is full of Corollas right now lol

thanks for your response..

i have saved some important pointers from this thread about the swap.

another question is do we need to have a piggyback ECU to tune the A/F mixture? since we are running 55mm TB, doesn't that make the fuel mixtures lean?


so basically what i understood on my back-read.

• 1st slap in 1zz-fe TB in the intake manifold. screw 4 screw
  
• plug the connector
  
• look for the epoxied screw, and adjust idle to 600 - 700 rpm

then ENJOY??
