For all the gen. 2 guys, or maybe even any knowledgeable Toyota guy....

So I sucked it up and instead of getting rid of my car, i got another engine for it cuz I really need this car while my other car is being put together. I got another 2vz-fe from a engine place down here in So. Cal. cuz I got a hell of a deal on it. For those of you who are about to ask me why I didn't go 3S-GTE, I would tell you that I would need you to donate me some money and some time to actually do the swap and get the car running correctly. Let me remind you that a 3sgte to a vzv21 chasis Camry has NEVER been done before, only to the sv21 chasis. Harness would have to completely be custom made and I really don't have the time anymore to do that type of stuff cuz yes, I even though I have a show car, I do build my own cars and do all the motor/electrical work on them.

But anyways, here is the issue at hand. I got my motor today cuz I had it delivered and I looked it over and didn't think anything of it cuz I was busy working. A little bit later on, I took a look at the tag on the motor and the tag read "4VZ-FE". I was thinking to myself, "what kind of place is this, they can't even get their engine codes correct?" And again I thought nothing of it until I came home and decided to research some tranny stuff on google and ended up on some new zealand lexus site or something where once again, I saw "4VZ-FE". Turns out that the motor actually exists and was available on 2.5 Windows/ES300's. Then I thought back to when I was in Japan and I was lookin at Windoms and was wondering why some of them had 2.5 liter engines in them. They were like 2.5x models or some crap. I always thought that they stuck to the 2VZ-FE motors but I had a conversation with Wraith aka Justin and he was telling me to swap in a 2MZ-FE, which is the smaller (displacement-wise) version of the U.S. 1MZ-FE. As you all you, japan also had 1vz-fe motors and they were essentially smaller (displacement-wise again) versions of the 2vz-fe. And after comparing specs to both motors, both the 2MZ and 4VZ have the same displacement, bore, and stroke (roughly). So now thinking back on how the 4VZ-FE was available on Windoms, doesn't that pretty much mean that the bigger displacement 3VZ-FE's and 1MZ-FE's would fit into a vzv21 chassis? I know the 3rd gen. Camry's and the ES models al use hydraulic engine mounts and the vzv21 did not, but would the vzv21 mounts fit onto a 3vz-fe/1mz-fe or vice versa? I think I have throughly confused myself now and am stuck wondering if I would be better off running a bigger motor on my car instead of the fabled 4vz-fe that I am talking about. I have also heard that the *vz-fe engines all share the same block. Can this be confirmed? Cuz if so, essentially I could use either of these engines on my car barring the concern of course that the ECU's are different and the harnesses are different. The harness itself I am not too worried about cuz I am sure they would share similarities to eachother as well, like the other model camry engines.

Anyone wanna throw out some knowledge and help me out before I decide to do the swap?

And also, if you used say, a 3vz head on a 2vz block? It wouldn't really make it a frankenstein motor if they share the same iron block right? And yes I know that 1mz's are aluminum.

First, verify that the motor actually is a 4vz-fe... It should say somewhere on the motor.

Any VZ, MZ or S block'd motor will bolt to your tranny, so that's no worry. If its from approximately the same year 'n stuff, it will probably have the same wiring harness, or at least work w/ your current harness. I know people have put the 1vz-fe in place of a 2vz-fe with the 2vz ECU and harness without problems (that they knew about, at least). Any VZ motor should bolt perfectly in place, barring issues with the exhaust (routed over the tranny on your car, under the motor on most other V6s I've seen).

Hope that helps a bit...

PS. Do you still have the custom Momo seat brackets that you were going to give to Brian so long ago? I could still use them.

On a related but unrelated topic...
I'm in a '93 Lexus ES300. It has the stock 3VZ-FE and tranny (don't know the code). I want to know what a feasible swap would be, not involving TOO much work or downtime. Here's my thoughts:
The newer ES300 (3rd gen., '97 - '01) ran a 1MZ-FE. Same displacement, but higher horse and torque rating. Would a swap be relatively simple, and what would be involved?
The other option was to take a newer 5VZ-FE from a 1997 Tacoma.
Also, would either of these require a matching tranny from the donor or could I keep my current tranny?

Appreciate the help / info.

I would suggest against it. While physically it would fit as MZ and VZ engines were put into the same cars, the MZ engines are OBD-II while the your 3VZ is a OBD-I dinosaur. Converting from OBD-I to II would be quite a chore.

On the other hand, I have no idea if the 5VZ would work or not. I'm guessing not easily due the fact that it IS from a Tacoma which is quite different from a Lexus ES/Camry.

PS: Oh and, start a new thread next time. It would be easier for you and for everyone and try not to dig up old stuff.
