Camry & Solara LoungeDiscussion area for every generation of Toyota's family car, the Toyota Camry. Lexus ES250/300 owners welcome! Topics of discussion range from fuel economy, safety, modifications, performance and more.
Is it worth the extra bucks for the model that has the 1MZ-FE engine as opposed to the 3VZ-FE taking into consideration build quality, refinement, how fast etc. Im not sure of the main differences other than the modest power increase in the newer engine.
I 100% dissagree that the 1mz will handle more boost stock.
IMHO with good tuning (so you dont melt a piston) a 3vz can handle 325fwhp or so assuming you don't get one with really shitty rods. If it is unlucky enough to have really shitty rods, they'd have broken and been replaced a decade ago anyways so you're all set.
The MZ's will have more horsepower(stock), but the cams in the vz blocks give nearly 100% of the motor's torque @ 2500rpm and 4400rpm. With a little modding you can have 90% of the motor's torque avalible through out the range.
VZ also has a distributor Very easy to use a single programmable piggyback computer to varry the timing by different amounts across the entire rpm range.
If you want to spend $400 in mods you can not only have as much hp as any of the 1mz's you can keep that Toyota truck v6 torque curve we're blessed with.

btw the 3vz block is iron while the MZ's are aluminum.
People forget two things here... It's the piston sleeve that has to directly deals with the power, not the iron block and the MZ's weigh 100lbs less.
I still like the 3vz better. It has the torque to lug around it's weight and if nothing else the the iron blocks put more weight on the drive wheels. They also don't strip out if you feel like cranking down hardware.

that's what I was about it say - if you're resleeving and doing internal work anyway, then the 1mz may be a better choice just because of weight
and problems of traction and power at low rpm in regards to the 1mz, those can both be solved by the use of an lsd and a 5spd to stay in the power band more efficiently

For simplicity, 3VZ is the engine of choice. The 3VZ will for sure handle a lot more power in stock form just by looking at the internals and with it being an iron block. Fuel and ignition management is also much simpler with an OBD-I ECU and using a distributor.
If you are on a journey of boost, 3VZ is easier to work with.
The 1MZ is great with the aluminum block and iron sleeving... It will hold up the power with no problems as long as the internals are replaced with forged ones. The engine geometry is also better on the 1MZ with lesser stroke, longer rod (much more rev happy). The 3VZ has a longer stroke and a powerband that is too shortlived (power comes too early and will die off at higher RPM's).
But to rebuild a 1MZ with forged parts, they will have to be fully custom. You also have to be best pals with an engine builder who will only charge for the cost of parts and accessories for the machinery. Or else, you'll be paying through the roof.
3VZ-FE = good for boost in stock form, cheaper to play with
1MZ-FE = great potential for power, but comes with a high price tag

^yeah. I think some increased lift on the cams would cure the high rpm die off. Then again the motor doesn't mind turning 7000rpm on stock parts if you have the gearing, and/or power to do so. Titanium valvetrain bits 'w stronger springs allow really high rpm range.(7500rpm) It works on both the 5vz-fe and 3vz-e. Why wouldn't it work on a 3vz-fe?
Like Tony was saying. You don't have to resort to all custom forged bits on a 3vz. You can find the pistons and rods. It's all ready-made for the 3vz-e by a limited number o hardcore places anyways.
I'd rather play wth a 3vz, but that's only because VZ blocks are more proven on making power. Tony is the only big power MZ I know of and will likely remain so for quite some time.
