I recently picked up a 1zz motor to throw into my car to get it back up and running. The engine is from Japan and has a different valve cover, has the coil packs on the side of the head, not COP, throttle body is much larger bore, intake manifold is a 4-1 polished manifold (looks like a header as opposed to the black plastic covered USDM ), but the block and head are the same though. I was just going to strip it down and swap the parts from my old engine over, but if I can use these I want to.

Are the parts mentioned above compatible with the USDM ECU? Are these parts even stock or are they aftermarket? I can't get pics up unfortunately.

Any ideas? I am throwing it into my car late next week.

Hmm... I sure hope not...
Here is another picture. The block and head are identical to the 1zz-fe which is a 1.8 and not a 1.6, no matter the application. This picture was found with pictures of the MR-S. Unfortunately every site that has a picture of this engine is in a foreign language. lol.

sounds like a 1st gen 1ZZFE except you say it has vvti?
i was under the impression that the 1zz evolved like this:

I: aluminum 4-1 intake manifold, no vvti, some versions had MAP sensor instead of MAF
II: same intake manifold, VVTI added, MAF standard
III: Intake manifold changed to black plastic construction with short runners (new intake manifold design added like 5hp)
IV: Same engine but then with electric throttle.

What year is this engine you found? and is it possible to take actual pictures?

that engine's from a corolla, im 100% sure of it. Celica's and i think matrix's are the only two who have the same 1zzfe engine. All other 1zz are not the same.

Ok. Thanks guys. Will it match up to my 5spd and match the celica mounting points? There are no way to get pictures. I am in oregon and the engine is with my car in WA, I intend to go up Weds to start the swap.

Sounds like if I can use this engine I would have more power if I used my intake and stuff.

This is kind of a bummer because I was told that this was a 1zz-fe Celica engine and they also assured that it has low miles and isn't older than 6 years.

I intend to. I know that emissions are different in Japan so it made sense that some of the components would look different. I got this through an engine importer and took their word. I am going to call them monday and see what they will do for me.

All celicas are from Japan never built in the US so I dont understand when you say JDM motor?

Ok I before I start the process to return it to the company, Id like to know for sure that this wont work. So the question still stands. When I strip this down to the metal and throw all of the electrical, pulleys, mounts, valve cover w/ COP plugs, knock sensors, etc that I took from my Celica, will it work?

This is an older generation 1zz-fe but it is a VVTI engine 16 valve, same as the Celica 1zz. Where is the VVTI Sensor? I have one from my Celica engine and can swap it over if it will work.

I know how to turn a wrench but I don't know the specific details of the engine's history. I know that the Celica is a Japanese made car, but I know there are differences between the Celica driven in Japan and the Celica driven in the US (I.E. RHD and their stricter emissions standards). I am not throwing JDM around as a buzzword, I just want it clear that this engine was not driven in the US. I didn't know that the engine on the Japanese model was the same as ones sold in the US.

What makes the difference between a 140hp factory 1zz-fe and say a 130hp factory 1zz-fe. Are there internal differences? Or is the extra power made from better manifold design and ECU, etc.

Bottom line, I have this engine and I want to get my car finished before I start school again next week. Waiting for the refund of this engine and finding a new engine takes time. I feel dumb for putting myself into this position, but I am living in Oregon and working on the car in Federal Way when I get a few days free here and there. I came across the engine and jumped on it before I really did my research so I had no choice but to take the word of the dude at the yard. The engine has a 1 year guarantee with $600 towards installation of the new engine if I don't want to put it in myself.

Ok. I guess you all are right. I don't know how old it is or how many miles it has or even if it has the same internals.

Back to the drawing board.
