vvt VS non vvt question?

[osot]

I am planning to buy a used JDM avalon engine that is Non VVT-1. My first question is wether the orignal Avalon engine is vvt or non vvt? Will a non vvt engine be compatible with my 1996 avalon? Can some one tell me the differecen between vvt and non vvt? Is one better than the other, and if their a difference can one one tell me the difference. Do you guys recommend for me to get a non vvt over a vvt ot vise versa.

any info regarding my question, I will appreaciate.

Hmmm....why are you looking at a JDM engine?

There is no guarantee that a JDM engine will meet US emissions specs, so
you may have to spend more $$$ to get it up to standards.

That is one of the missions of the VVT-i engines. The other is, for the
same amount of displacement, the VVT-i acts like a larger engine. It does
this through Variable Valve Timing...adjusting the timing of the valves
according to load, engine speed, etc. So, with the same displacement, the
engine can produce more HP on demand.

If you've driven you Avalon with the VVT engine, you're probably aware of
the 'kick in the pants' you receive when you press the accelerator at
highr RPMs. That's the valve timing making adjustments.

My son has a muscular 1996 Mitsubishi Gallant (Sp?), and he says my Echo has
way more 'balls'

POS!??"

There is no VVT-1. There is VVT (variable valve timing) and VVT-i (variable
valve timing with intelligence). Not to sound condescending, but an engine
with VVT or VVT-i has variable valve timing and an engine without VVT has
fixed valve timing. Besides performance, there are differences in the
camshafts, head, and computer.

To answer your question, it would help to know where you are located. All
other things being equal, VVT is better than no VVT and VVT-i is better than
VVT.

Based on the questions you are asking, my recommendation is to get an exact
specification replacement engine because the complexity and cost to change
over will be more than the benefit. You will probably have to change the
engine room harness, ECM, and a bunch of sensors.
