3VZ-FE V6: what are the limits? (performance mods)

What are the practical limits when it comes to performance modifying a 3VZ-FE iron block V6 motor?

I've done nothing to it as of yet, and I'm fishing for some general ideas as to what can be done and what can't.

The motor runs like new and has 98K miles on it, and has been driven very gently in general.

I think the most tuned 3VZ (or is it 1MZ?) is pushing 280whp right now with the aid of a CT26 turbocharger. The tranny however would be the weak link, unless you're blessed with the E153 which came in V6 Camry's as well as the MR2 Turbo.

Well, the car the motor's in is a '92 Camry V6 LE, and it's all original.

So I should have that tranny, I guess?

The stock 3vz engine can handle about 280hp before you become in danger of burning a piston. Replace the pistons with forged ones and you can easily push 400hp (with boost of course).

There is no limit to that engine with the exception of your money. Built and a blower and you could be pushing 600whp+ safely.

Just swap out to a manual tranny and you'll be fine. The auto tranny offered with the 3vz can only handle about 250whp before it starts becoming a problem. And that's only if you beat on it hard. The non-built manual tranny can handle in the range of 350whp before you need to start considering upgrading it.

What similarities does that engine have to the 3VZ-FE that was used in the trucks and 4Runner (3.0L SOHC V6)?
I know that in it's day, that engine wasnt very impressive in the trucks. In fact, when the 2.7L came out it was almost equal to the V6 in terms of power and didnt have any of the headgasket problems the V6 had.

the camry's 3vz-fe has a few differences, parts of the blocks are different compared to the 4runner/truck 3vz-e, the 3vz-e was a great engine for the trucks, its even better with dohc, breathes very nicely


check out http://www.doaracingengines.com/

contact them, they can set you up with lots of parts that fit the 3vz-e as well as the 3vz-fe, but the fe parts have to be custom ordered, they can also build you an engine, keep in mind a fully built 3vz-fe will cost about $8000 thats with forged pistons, rods, machined crank, having the block machined, very expensive but totally worth it

$8000 for a full engine build??? That's dirt cheap! I have seen people ask as much as $12k to do the work/w parts.

ilke every one said your limit is the money not the motor. you could make the motor do 700 hp and run fine but then the trans cant handle it, if you make the motor and trans work good together, the axels wount stand it, thin you got suspension that isnt meant for that force. tuning goes in 3 stages
1) find out the money you got to spend
2) find the power you can aford
3) find or make the parts you need to do it

after all that you will still need money to get it going

I had a 3vz motor in my 91 toyota pickup 4wd with an auto tranny. I opted to put a 125 hp shot of NOS on it when I was in Highschool and the engine ran fine. even better with the auto tranny..

Cool

^ lotta differances in the 3vz-e and 3vz-fe.

Only thing they really share in common is combustion chamber size, and basic block construction. Many of the sensors are different, about all of the major parts in the block are. obviously the heads are.


3vz-fe limit??? We'll know if McElligott blows his up.
Remember previously he was running around 250hp n/a, with a 125, (and later) 150 shot of juice on top of that... (what does a 150 shot normally average out? like 160-175hp?)
There's your 375-400hp. Only major change there was a copper head gasket when he had his port & polish done.

So I think it has as much potential as anything else N/A.

The block is DUH
the crankshaft is the strongest you'll find in any of the "older" v6's
rods are not great, but the strongest you'll find in an "older" v6
The pistons are sucky...

They're basic cast aluminium.
The good news is that their is no reason why someone can't make over 320hp with them, with some descent tuning. They'll probably melt a hole in themselves, or melt around the ring seals somewhere between 370 and 400hp, if they scale with similar construction toyota pistons.
So... The good news is if you know what you're doing, you shouldn't have a problem getting a good amount of power out of it. If you're good at tuning, the engine would break the stock transmission/drivetrain parts before it would die hah!
