3mz fe vs 1mzfe

[duckie77]

my motor is pooched, uses 1 liter(quart) of oil every 200 miles. I have been trying to research swapping in a 3mz fe in place of my 1mz fe, but I am having issues finding anything. So all you Toyota experts out there, what is the difference between them and can it be done? BTW my Solara is a 1999 and i do have the S/C and it is an A/T car.

Ask about the 3MZ/1MZ hybrid engine, I think GregTRD built a couple of these.

trd4life gabe is the man to talk to for the hybrid.................

[GreenSolara01]

Sounds like a good time to make a tutorial for it take some pics if you go through with it.

[SleeperSolara]

Yeah i got a whole list on what parts i need from the 1MZ.

You should talk to Gabe about buildin' you a 3MZ / 1MZ hybrid motor.

To do the hybrid all you need is the 3mz short block. The rest is 1mz. If you want to do a complete swap, you will have to do a crap load of wiring and electronic crap and that's gonna be one expensive pain in the a$$.

It is not a direct swap exactly, Gabe informed me that the block has to be machined in some way to redirect oil to match up the block with the heads. He didn't know the exact procedure, but that's what he told me.

He also told me that he could get me a ready to swap short block for $1000-$1400. So talk to him and he can hook you up.

Oh yeah, If you are burning oil, are you sure that you have bad rings, or could it be your valve guides. If it is your rings then the hybrid will help you. If it is the valve guides you will still burn oil.

One more thing, the hybrid will raise compression to about 11:1 too high to safely boost. So you will need to ditch the charger or put different hardware in the short block to lower the compression ratio. Unless you plan on running crazy fuel an reinforcing every piece in the engine.

If you're about a full swap of the 3MZFE then that would be a headache.
From what i know about the 3MZ / 1MZ hybrid, is that Gabe blocks the 3MZ VVti- oil passages..... I could be wrong.
Like i said you can have Gabe build you the motor wit different pistons so you can still run the S/C.

Ditto Sleeper. I bet that's all it takes. I might actually be able to pull off doing that myself, now you've got me thinking...

Yeah i've been thinkin' about doin' it myself, but i've been tryin' to figure out how would you plug the VVt-i oil passages....

[duckie77]

thanks for all the input, got me thinking about the hybrid. actually found some info on it as well. Apparently pretty straight forward other than blocking the VVT oil passage(which is an aluminum plug). Out of curiousity, does the 3mz have the same sludge issues??

Cool.
I'm not sure.
The 1MZ sludge issue is only happenin' because of the type of oil bein' used, IMO.
I've pulled off the front valve covers on some 1MZ's at the salvage yard, and most of them didn't have any sludge build up at all.
The ES300 i'll be pullin' the heads off has no sludge what so eva.

[Gibson99]

on most of the sludge engines i found at toyota, the engine still had the factory original oil filter on it. at 30k+ miles.

always use good quality oil AND filters, not the cheap crap from "iffy lube". synthetic is not necessary if you keep up with oil changes and don't let the oil level get too low via leaks.

if you do go cheap, make sure you change it every 3-4k miles.

[duckie77]

this car has always had synthetic oil in it, only has 167 000 km's (just over 100 000 miles, but it was parked for 1 1/2 years and has used since it was put back on the road, but just lately has gotten really bad, I figured that if i am looking at an overhaul, might as well look at options. No replacement for displacement eh . I don't actually know if it is sludged up, but kind of assumed being as it seems to be an issue with these engines. guess I'll find out soon enough.

[99BlackSandv6]

My engine has no sludge issue, I agree that it is probably based on the oil used.
Does anyone have a good picture of the VVTi passage that needs plugged, I've searched the web with no luck. I would love to build a hybrid for next summer.

Yeah i've been tryin' to figure that out and what to use when pluggin' up the VVT-i oil passges.....
