I don't know the OP's reasons for the 3VZ but this post makes a good case for it being better then the 1MZ:

I wont say any of that is outright incorrect, but it is of little concern. Very amateurish stuff.
ECU stuff doesnt matter. Any serious use is going to use an aftermarket ECU.
The resistance to det thing means nothing. More advance without det != more power.
Huge gains from head porting means its an average head to begin with.
etc, etc.

the weight gain from the 5sfe to 3vzfe conversion was 58kg weight gain, which can be offset by weight loss in a race trim car, and understeer dialled out with suspension settings.....
60kg is a lot to loose over the front axle. You cant really do it without major front end work (fibreglass everything, spaceframe front end, etc).
Any suspension setups you make to help handle that extra weight, also would have made the car a lot faster if you didn't add that weight.
It aint that easy.
You've selected an engine thats great for reliable bulk power, but *will* hurt handling... and the events you want to do are exactly where you need great handling over power
Its like the guys who put heavy & long JZ's in their 70's Celicas, Corollas then want them to go fast around corners. It just doesn't work that way.
I will respectfully disagree but not on everything....
how much extra would 3sgte and awd transmission way more then the 5sfe, I would imagine without weighing, ( which now that I think about it, I might actually do that) an estimated guess would be at least 30-40kg,
3sgte - 3vzfe would be I imagine a 20kg gain,
offset that with lighter bonnet (stock bonnet 25kg), lighter bumper, remove big chunky front reo bar (10kg), tweak suspension, move battery, that 20kg is offset, the only addition to weight would then be the turbo necessities for the v6,
then it would just come down to how it was driven, with good knowledge and some talent the understeer can be overcome if not minimised,
from there any other weight saving that can be done can only have good effect on vehicle weight, handling, suspension and rigidity is also very crucial in this....
so while I agree with some of your points, I also have my own view on many of your concerns, and I guess the proof is in the pudding when all is said and done, so we could banter all we want but we wont know till its done and tested......and if it works out you were right I will shake your hand and apologies.......
I think it will be a balance of both to be honest.......
however lets be realistic, the gt4 isn't the fastest track car, or we would see so many more of them, I imagine the cost to reward is too high, when there are other better base cars out there that can be adapted for less cash outlay to reward.........
I never expect this to be easy, and I am under no assumptions and my head isn't in the clouds...
I like challenging myself and if I wanted a fast track car with ease of modification and cash to reward outcomes I would most definitely gut my gt86 and turn that into the track car,
im not out to set any records, im after a fun, competitive car, not a front row machine.....
I don't mean to step on any toes either, and im all for input and ideas and I appreciate your input and advice,
at least it gives me more areas of thought to minimise and ill effects, time will tell I guess, and please keep checking in on progress, and advice I you feel its needed, I will either leave it or take it on board.....
