The only performance that will be affected will b fuel consumption. The 1zz n 3zz will perform better than your 4zz. But not that it comes with higher fuel consumption. Make sure u buy the ECU that comes with the engine or you take yours for mapping. Our mechanics can be funny. After the engine change without the right ECU, you will encounter issues that may frustrate you to sell your car

Thanks a lot Ironheart. Pls interpret ECU to a laymans understanding so the mechanic or parts seller will understand. Whats the popular common name in the market? Thanks.

Oga gazzuz, im thinking of changing to a bigger engine if it wont affect the performance of the car. Before the car developed engine problem, it was shorting oil and of course I had ringed before. So I want a better engine. But if there's no alternative, then how much last price will it cost to buy the 4zz and send to Abuja . Thanks.

kingi777:
Thank you once again Iron heart and Gazzuzz, God bless you for your contribution. I will maintain the 4zz which came with the car to avoid headaches associated with engine swap.

kingi777:
Where? Lagos or Abuja bro?

kingi777:
I bought 4zz engine but after fixing it into the car, it was giving us a knocking sound. The saler has agreed to changing it for us. I pray I get a good engine, thinking of 1zz engine.

kingi777:
Oga Gazzuz thanks for your concern. A friend suggested I transfer my camshaft to the new engine I bought if there's no any better one to replace it. Note the rim of my engine block melted that's why it's irreparable. The picture is attached. Don't know if it will work?

GAZZUZZ:
Now here's the next issue you will have, the 4zz-fe you have there and the 1zz are similar physically but have different bore sizes and pistons. Another technical part that is different is the timing rotor which is on the crankshaft. You will have to remove yours and install on the new engine you are buying if 1zz-fe. Doing that your self will void warranty and return by the seller, so it's better to tell the seller to do it for you. Without swaping the timing rotors engine will not start.

kingi777:
Ok Mr Gazzuz, I will show him as soon as we meet this morning but[b] I think he changed it(timing rotor) yesterday[/b] because I told him after reading your comment.

The engine I bought about 2 weeks ago has been a torn on my flesh. It runs fine o but swallowing oil any how like the previous engine I changed. I was managing it until the car stopped me on the road after I noticed it was making noise. Mechanic confirmed it was chain issue but that I could manage it until I decide to get it fixed. Now the car got a lot of things damaged when the engine was opened. The engine itself was ringed but not properly fixed the reason for oil shortage. The two times I changed oil, after 2 days, oil became so dark. Note I spent more than #200000 changing the car engine. 2 days ago, I gave #30,500 for parts including rings. Yesterday the chain roller was shown to me that has to be changed because of crack. Hopefully after grinding the top today, the car can be kick started.
Lesson: Since ZZ corolla engines below 2005 models have oil shortage issues after 120000 millage, be careful unless you want to change rings. Before buying engines, make sure you verify because most of the sellers are terrible without the fear of God. Immediately money enters their hands, story changes. Before you buy a car, google it so that you get basic information about it from previous users. Thanks.
