HaHaHa You think the damn VQ is better than a 2JZ-GTE? Keep dreaming.
The VQ is an amazingly strong motor I would not give that up!!!
VQ's have more TQ overall, with big valves and crazy port/polish jobs we are going to see some big power comming out of the VQ's very soon. RB26's, 2JZ's are all good, but they are old technology. Give the VQ 10+ of development time and let's see how things turn out.

Well it starts on Saturday, I will post pictures if everything goes right. Thanks for all the positive and negative feedback. Should be a fun month!

I wish you the best of luck man. What turbo setup are you going to run? Talk to Larry at Sound performance he knows his **** when it comes to supras.

[QUOTE=trefling]No disrespect but all the big HP Supras are always running around 30 pounds of boost. Nobody knows for sure how much power the VG will have at that levels with supporting mods, I think the VG will surprise some people in the future.

LoL You have to be kidding.
The reason you boost more is because you have low compression pistons. If you run 11.5 to 1 compression you cannot boost 25 psi, its a simple rule of engine mechanics.
My argument is the stock 2jz-gte block and heads are badass for making power. The VQ is an awesome motor, but the TQ numbers are off the wall impressive. All "V" shapped blocks make insane torque, look at the 3kgt's they made tons of torque.
Stock block, the VQ is made for N/A and the 2JZ-GTE is made for boost, simple as that. Modified block is a different story because one is 3.0L and the other is 3.5L.

supra motor at 400whp vs a 3000gt motor at 400whp. The 3000gt motor will have more torque at high rpm's.

So let me see if I understand this right....you can't take a stock VQ motor and run 25psi of boost?
Just kiddin man, I know the 2JZ is badass, built for boost from the factory. But I do believe the VQ will pass it up in the next few years.

All else being equal, an I6 configuration will be the torquey-er of the two.

I believe the I6 is smoother yes, but I also believe V type engines create more torque also because of their bore size. Maybe I don't know anything about engines but from what i've seen and experienced, V type engines make more torque.
For example, look at the 300zxtt's vs supratt's, the zx's make more torque and they are 3.0L v6 just like the 3000gt's. I'm not bringing this information out of my *** dude. I understand what you're saying as well, but this is what I believe, thats all.

But if you bolt on a tt kit on a VQ and a 2JZ the winner will be the 2JZ. The VQ will blow faster than you can say "pop". Supras have gone over 1000whp on stock block, I believe thats quite an achievement.
Don't get me wrong, i'm not saying the VQ sucks. It's a great motor, especially with the torque numbers it produces. But when it comes down to forced induction and bolt-ons, you cannot mess with the power of the 2jz. Those bastards never blow.
P.S. RB26DETT also is one of the greatest motors built because of its high hp & high rpm capabilities.
To answer the original post, I think its worth it if you are not going to pay for any labor.

You are really comparing apples to oranges. An Inline 6 is fundamentally stronger than V6s because of the 7(?) main bearings vs. the V6s 4. Plus the inline 6 is naturally, by design, better balanced than V6s.
The biggest problem with the I6 is it's size.
Edit: Also don't forget that in this case that you are comparing a cast iron block to an aluminum block.
