94 Lexus ES300 engine?

[koji]

I've found a local Lexus es300 complete parts car for $700. At least, that's what the ad says. I'll know more once I get there. If I see 3VZ on the engine block I'm just going to buy it.

However, assuming I get there and the car is in fact a 1994 and does in fact have the 1MZFE engine - why aren't these engines recommended? (per the sticky).

I've searched but come up with not a whole lot to go on.

Thanks in advance!

they are recommended if you can diagnose every problem yourself due to OBD2, the 3VZ is OBD1 and less likely to throw codes.

ku-sama did u get the pm i sent u bout ya situation

[koji]

I somehow doubt the 94 was ODB2. ODB2 didn't become mandatory till 96'.

[Maruki-kun]

yes. keep this thread on topic. I appreciate the in put, I called an attorney.

[lucky_charms]

aite jus tryin to help

The 94' Camry and ES300s were one of the first cars to incorporate OBD2.

wiring could be interesting, im assuming this is the 6coil system before they went to the cheaper 3 coil waste spark. if you do get it wanna donate me the rear bearing and front hubs?

to tell you the truth i was a bit confused about the 1mz vs 3vz debate. i understand that the 3vz has it's advantages but i figured the advantages weren't that great. from what i've read there isn't much difference, and from what i've seen after taking apart/rebuilding numerous engine i prefer the 1mz. if you look at tony the tiger's v6 camry he was putting out great numbers with the 1mz and an apexi safc, that's even before forged internals. also if you look at the v6 solara and camry's that have been supercharged their putting out good numbers too. i think it's just easier to tune a 3vz being that they are a more basic engine. personally i like the 1mz, probably cuz i've been working for toyota for a while now and haven't seen many problems with the 1mz. i know tuning might be a bit more difficult but i've read good things about the aem fic(supposed to be easier to work with than the emanage for obd II cars). my setup will be really close to tony's camry. i will be rebuilding the supra ct26 shortly, as the mr2 will be getting parked when i do the paperwork on the 96 subbie i picked up. i know that i will have to install forged internals, but i would have to do that with a 3vz as well. everyone has their prefference, but i chose the 1mz for weight, reliabilty strenght and tunability after i get the fic. honestly i think i like it better than the 2gr, for now at least. most likely because of the price and availability. for the price of an engine and install you could have a monster 1mz or 3vz.

Just a heads up, the aem fic cannot advance timing...it can only retard, which makes it useless in a NA application, and maybe marginally useful in a boosted application, I don't know if you will only be retarding timing.

but one of the major things is how will you control fuel? the stock injectors are pretty small on both the 3vz/1mz, ~250 cc/min on the 1mz and ~240 on the 3vz
Injector flow rates and part numbers (3VZ, 1MZ) - Toyota MR2 Message Board

for comparison the gen II 3s-gte is 440cc and the genIII is 540cc

If you want real power(250 whp+) on either the 1mz or 3vz your going to need to turbo. The 3vz lends itself to turboing much better because of its ignition system, lower stock compression ratio, and iron block, and the OBD-I is much easier to run a piggyback such as the EMU. If your going standalone then the OBD-I/II don't matter.

ive seen like 7 3vz engine when i went last week.
does this take alot of money and fab to put into a MKII?

[koji]

Define "a lot of money". It's seriously a relative scale. From my research it's like $2-4K. To me that's not a lot but for other people that's another car.

Turns out I won't be getting the car that caused me to start this thread. Some jackass who pulled some parts out of it cut the body harness and took the plugs. The fuel pump isn't getting any power. Wiring is the hardest part of this swap and I'll go through the pain of a normal swap but not the additional pain of trying to figure out what goes where on a hacked harness.

Oh well. So much for my cheap donor car. I'll keep surfing for a 5spd 91-92 Camry.

no, it can be done for dirt cheap if you know how to do wiring/weld, and if you don't 4v6 sells the passenger side motor mount, which is the only custom thing you need and phoenixtuning or mr220v can do the wiring for you.

my entire swap cost me 2k to be fully plug and play and buying a jdm motor shipped to my door for 550, and that is doing it right, all maintaince items, new clutch/fw, etc.

You don't need it to be a 5 spd because you don't use the camry tranny you use the mr2 tranny, you can also use a auto ecu, or they sell 3vz/1mz manual ecus for really cheap on car-part.com

the 92-93 camry/es300 is the 3vz-fe
the 94-97 camry/es300 is the 1mz-fe

[Lil_Revolution]

your right about the ignition and internals but i don't know about the whole iron block thing. i haven't seen any cracked 1mz blocks due to too much power, it's mostly internals. to tell you the truth i'm going to be replacing the internals in mine after i turbo and tune it. as far as injectors i plan on going with supra injectors down the road. I didn't know that the fic could not advance timing (thanks for the info), but i'm going to be using this for a boosted application. like i said i went on weight savings and potential power. i was thinking that i can allways make a 1mz stronger but i can't make a 3vz any lighter.

That's because the engine is ingesting the amount of air of a larger displacement engine, so the fuel requirement is much higher per cylinder.

440cc x 4 cylinders = 1760cc
295cc x 6 cylinders = 1770cc

It's important to incorporate the number of cylinders when assessing injector flow against engines of varying induction types. The returnless 1MZ uses a 50psi in-tank FPR, which will vary at the fuel rail. The BSFC will also be different.

All 1MZs are OBDII, once again. 1994s are partial OBDII, meaning that they don't have all of the standardized codes to report.

The problem with the 1994 1MZ is that the harness and components differ from the 1997-2001 1MZs that have a switchable A/T <-> M/T ECU. If you use a standalone and don't have smog requirements, any 1MZ will do fine. However, using the OEM ECU on the 1994-1996 1MZs requires tricking the ECU to believe the A/T is there.

That's the last time I'll explain that.
