[vibe13]

What does the 2zz injectors do? Will fits a o3 vibe 1.8L ??? More power is it worth it? Getting it .what different will it makes on my car???

I don't understand your question - though I probably would not be of any help even if I did. But others might.I think I have read that direct injection does have a beneficial effect on power and/or fuel efficiency. Is that the issue?Aside from that, 99.99% of the claims for devices etc. that provide more power or better gas mileage are dubious. If there was a cost effective way to increase power and/or gas efficiency with a certain spark plug etc. the thousands of engineers at Toyota would surely have found it and for competitive reasons Toyota would have implemented it.

My bad my question is about power will they give me more power? If they do is it worth it meaning it wont do no damage on a 1zz?

Not really. Although they flow more your PCM will simply alter their timing and you probably won't notice any difference.Start with a CAI and maybe some exhaust work

Are you asking if there is any benefit to putting 2zz fuel injectors in your 1zz engine?If so, I don't think it'll be much of a benefit for power OR fuel economy if it even runs correctly. The 2zz injectors have a higher flow rate. Is your car stock?I'm no expert, but if you aren't heavily modding your car for more power I don't think you will benefit from the increased flow of 2zz injectors. If you were going with forced induction or heavy modifications that might be different...

this is all i got right now. obx exhaust manifold headers,performance chip utp ultimate tunning and performance,billet front strut brace bar,engine air filter kit and universal cat 2.50 i cut all my exhaust and just run a tube all the way to my muffler and whats and CAI????

CAI = Cold Air IntakeSRI = Short Ram Intakeyou seem pretty "power hungry"...Maybe you ought to save up the cash and just find a 2zz in decent shape

The injector won't do you much good unless you have a Piggy-back ECU that will control the fuel and timing but even then with some type of FI (Turbo or SC) your gains will be small. There's some used 1zz Superchargers floating around for less than $2000. How much you want to spend? Please do some research!BTW that performance chip (UTP Perfomance Chip?) you have is CRAP! It can AND will cause harm to your engine. Remove it!

However the ECU also checks the O2 sensor and will adjust for it. You could reset the ECU every week but then you risk frying your engine by running lean. If you remove it, reset the ECU.
