Didn't realise it was one of the all alloy motors with plastic manifolds, yeah it should be significantly lighter

It's an all aluminum motor . Intake included lol
I liked the fact that it didn't change the way the car handles at all.
She still drives like a normal celica till you really push on the gas

kurt, how involved is the wiring for the 1mz swap? What harness is started with and what needs to be changed, in a nut shell?

To be honest I'm not 100% on what all changes for sure
I know the 6gen fuse box gets wired in the correct plug for the speed sensor
Then it has some wiring to deal with the trans codes since most 1mzs were autos
An just moving stuff in genral to match where it should run on the celica

Smaay could probably tell you a lot more on the wiring
I sent mine to Mr220v to have it done. It cost like 350+ shipping both ways

Grea, thanks for the info

Does anyone know if the 2GR block and E154F trans will not interfere with each other? That's another motor I came across as a possible swap..

the 2GR will bolt right up to the E153. no problem. I still suggest you stay away from the 2GR. yes it makes awesome power but they do have a tone of issues that need to be corrected. Personally i would go with a full 3MZ or a 1MZ/3MZ hybrid like i made.

the 3MZ has the plastic intake manifold and has changed over to DBW. it never mated to a 5 speed so you will have to deal with auto codes, although i hear they are easier to defeat over the 2GR codes.

the 1MZ did mate to a 5 speed and if you get a solara engine and harness, the ECU is the same one, you just need to ground a single pin and that turns it into a 5 speed. no auto codes.

now for the biggest hurdle. after messing with my swap for months now, i can tell you this, if you plan on going AWD with a V6, you will need custom header in the back because the stock header is not going to fit around the transfer case. there is not a lot of room back in there. im still fighting with the header and EGR port and hitting the steering rack.

one nice thing about the 3MZ is that there is no EGR, it has VVT, and its a good engine.

Glad you brought the header up smaay
I was thinking about that an forgot to post anything
Although it wasn't my egr that was hitting the steering rack it was my o2 sensor

Great info guys, thanks. Smaay, your 1mz/3mz hybrid, did you use a 3mz motor with 1mz intake? What else was swapped, fuel system? What did you do about the oddball motor mount situation? What else am I looking at for hurdles with a mz swap and how are emissions handled? Any regrets for the swap btw?

Whoa, sorry for the questions, not trying to overload you

You can handle the mount one of 2 ways
Modifies the stock gt mount with some flat plate steel so it can reach the mounting point on the Mz
Or you could always talk smaay into making you a mount like his
I know once I got the extra funds I'm gonna have him make me one lol

My only regret was not fully knowing what I was getting myself into before the swap
Other than that I love it.

im using the block of the 3MZ to get the 3.3L and the heads and intake of the 1MZ. im using 1MZ electronics and wiring. Because im in the communist California, i have to do it this way. even though the engine is newer than the car, it also must have mated to a 5 speed. as for fuel, i havent figured that out. I want to stay with a return system, but like Kurt mentioned, in 02 the 1MZ was returnless. that means i need to get a regulator and put it in the tank. Im not sure what california will want me to do. im certain ill ahve to add a regulator in the tank so ill have to do with the MR2 guys do.

It seems like I read about someone putting the regulator ridge outside the tank
Like it was in the sending line then it was t'd back into the stock return line on the tank

Are there any negatives to go with a 1mz head on a 3mz block? I'm guessing the wiring is much simpler with the 1mz harness, no? Any reasons to stay with a full 3mz?

My 2 main reasons for wanting the v6 is to be different and be able to supercharge it.

What the heck is this? ^^^^^^

Well I just happen to be lookin at random stuff on celica tech an seen this read it an thought of you
Should answer slit of questions on what to do for your swap
http://www.celicatech.com/forums/showthrea...Alltrac-writeup.

Basically the main thing I seen that will help you is the trans he used .
He didnt use the stock gt4/ alltrac trans . He used a 01-05 rav4 Awd 5speed trans
The transfer case is shaped alittle different an gives extra room for the exhaust
The only downside was the gears are alittle shorter. But...... The final drive is the same so the stock st205 rear diff can still be used.
That's just a quick run down of a small part of the thread. He goes through the whole build in detail (even gives a tool list lol ) on how he done his 3vz alltrac swap

Thanks a lot for the link kurt, the only downside is that I just picked up a 205 trans the other week, dummy move I guess, lol. Reasearch first Christopher (slaps head)!

Spare trans for the altrac u guess right lol

Lol, what alltrac?

Lol I thought in a earlier post you said you had a alltrac
Must have read wrong oops
