Don't waste your money on the 3VZE. It's a waste of time and money. Like teaching a pig Calculus.

Sure there's a ton of hopups you can add to it. Yes you can increase the power output by 10-30% (the computer will fight you every inch of the way.) BUT you'll spend a boatload of money doing it and end up with a very expensive marginal motor.

Take a look at the Vortec conversions. Many very professional kits out there. You'll get done for half the money you'd spend on the 3VZE and have more power in a stock motor (there's lots of room to grow.)


A stock 3VZE gets 85HP at the rear wheels.
A highly modified 3VZE may reach the low 100s.
A stock Vortec can get you over 150 at the rear wheels.

Do the math, it's real easy to see which is more cost effective.

 

i found this tread on a search engine so im gonna reply to it sounds intresting i know its really old tread but ill give it a shot, well you can get a lot of power from the 3VZ-E engine 250HP to be exact with all internals and custom parts but ur loooking at around $14000 quoted by toyotaperformance.com i think thats the site, but the guy i know here in canada who builds motors has people in places you can only dream of, who currently build engine internals they dont offer nutting for the 3VZ-E but can shure custom it on their spare time, but cost again, you can TT your 3VZ-E engine but here are the Prices well that i get.

The cheap way of doing it!
stock turbos of some car 2 of them $400
inter coolers $400
Custom manifold $600
everything els $600
Total $2000 canadian $1700US
Advantage Disadvantage
60hp max HAHAHA blown head gasket, 10 MPG, Full synt oil
every so oftin, efficency sucks, this option is for
ricers

A little better way of doing things

Head re shaved to fix that crappy head gasket problem $1000 (thats after i remove the head my self)

the smarter ricer

the real way of doing things
Head re shaved to fix that crappy head gasket problem $1000 (thats after i remove the head my self)
copper head or some better metal head gasket $400
Port and polish $1800 thats with a complete rebuild head with better valves and so on
custom intake manifold or bored out ones $600
pistons $600
Custom exhaust manifold $600
Proper turbo setup $5000
Injectors, ECU, and all the other stuff $2500
TOTAL $12,500 can $10,000US
Advantage Disadvantage
125hp max 7 MPG, Full synt oil, you gotta be mad, option for the rich

Proper option option 5VZ-E Swap prolly $1000 for me everyone els $4000
spend $2000 on that engine
headders, exhause system, intake, ignition amp, coils, electric fan, plugs, wires, custom pullys,

TOTAL $3000 for me $6000 everyone els
Advantages
everything total est power
245 hp at the flywheels
200hp at the wheels
went from 17MPG city to 25mpg

Disadvantages still cost money
