1ZZ TB/Inj/Rail/Coils

[H3LlIoN]

I have a complete setup off of a 1ZZ engine, includes throttle body, injectors, fuel rail and coils off of an 03 or 04 Corolla. Everything in working order, car had roughly 75K miles on engine when parts were pulled. These were not sitting out in a junkyard for months in the weather...parts came direct from dealership. I know TB will work on 1nz, AFAIK the rest will as well. Asking $200 shipped, cont USA

You may want to note that the TB you have pictured is NOT compatible with our cars as it's not a DBW throttle body.

[H3LlIoN]

didn't know that. Will see if I can get the right one.

[AlexNet0]

make sure the one you get is the one with the magic part number. There are 2.

kthx for the heads up

Will running this cause an issue a CEL? I have a 1ZZ TB now with no CEL. I have been debating upgrading to the 1ZZ Injectors but I am not sure its worth it.

[Gideon]

^ I've had my 1ZZ TB and injectors on for awhile now, no CEL. I do have a 1/8th" TB spacer installed as well though.

[Yariz]

Where did you get spacer? I haven't seen a need for it yet. Do you have to change anything other than the injectors? Rail? Also, did you see an improvement?

[Gideon]

It came from another YW member who had it custom made. The injectors were added as a result of a CEL which was a lean code, he said after he installed the injectors the code went away.

I installed both TB spacer and injectors at the same time so I can confirm nor deny if there was ever such a condition or if larger injectors solve it.

You don't have to change the rail, stock one works fine. Might want to pick up new injector seals depending on the condition of the ones that are on there currently. Less than $10 for all four, so it's worth it to be safe.

No dyno so no real numbers. Since I installed both a TB spacer and the injectors I can't honestly say which was responsible but it does feel like it pulls harder at WOT.

Gas mileage has not decreased, however at cold start you can smell the difference because of how rich it'll run when warming up.

[Yariz]

ok, sounds good. Where did you get the injectors? Do they usually run pretty expensive?

Why do I need that? My TB is working fine as is...:drinking:

Same YW member who had the spacer made, it was around $60 for the injectors, I don't know how much they are from the dealer. Sorry. :iono:

No, this spacer did not come from you. Mike (mikenacarato) had this spacer made prior to your's.

[Yariz]

Why do I need to get a spacer? Mine fits fine, and doesn't have a CEL.

to improve the air flow going to the manifold.

[Yariz]

Kewl well let me know if you guys decide to get an order together.

07 yaris s is that 1zz too?

[cruz-gsr]

07 yaris s is that 1zz too?

no, the s has the same engine as a regular yaris 1nz

[AlexNet0]

back on topic. is the 1zz throttle body still for sale? and PM me with how much for just the TB shipped to 04856

[MGargano]

I'd be interested in the injectors, if you're willing to split. Zip code is 07748.

[H3LlIoN]

TB is cable driven, so you'd have to do an xB pedal swap to make it work, or wait until I can track down the DBW 1ZZ TB.

How about the injectors?
