Even those motors are having trouble exceed 550rwhp on the stock bottom end. I know this cause we just put a blower on it. Even at 514rwhp it periodically goes into fail safe. There was also a guy that bought a 05 GT and put a blower on it from JBA and it was doing about 565hp and a week later he blew his motor due to a rod bearing cracking in half then caused the piston to bend the valves. This was caused by the inbalance of boost pressure into each cylinder. When this occurs one sides pistons are being pushed down harder while the others arent as much. When this happens on a v8 your crank starts to bend due to the differences of pressure on 2 different places. Ever try making a motor work on a bent crank? Its not a very pretty picture I can assure you. I am sure you can picture the rest.
To your 3rd paragraph. I dont know if you have read my posts but I have repeatedly said A"stock bottom end" I never said stock top end. Of course to get 800hp you will need better airflow. But the bottom end you dont have to touch while as every single v style motor you have to tear apart the bottom end and put better internals and blueprint and balance the motor better.
Inregards to your last paragraph. I agree with you. Every single toyota motor produced has literaly been strong. However, the facts still remain I6 bottom ends are much better to deal with than v6's.
Again let me make myself very clear. In my opinion you can get more power out of a V8 than a I6 but the V8 must be built right for that kind of hp. Now if a v6 was built right I would still say the I6 would be faster if they were the same displacement reason why is becasue a I6 has less metal due to the shape of the motor. A V6 weighs more. Therefore if placed in a vehicle of the same weight the I6 would win due to less weight.

your arguement was that the V6/V8 was less inbalanced so its impossible to make big power out of them .. a V8 is less balanced then a V6..
also you do know there is a 700-800hp 5vz-fe out there.. if you go up google im sure you ll find it.. its 10-11 second tacoma.. it claims it has stock buttom end.. i have a 5vz-fe in the garage rite now.. i can assure you its not some pos V6.. its built up like a tank.. 13-15PSI on street gas can make 400-500hp.. reliabley.. my friend has 300whp tacoma.. no intercooler.. has been running it like that for 40,000KM.. the thing knocks everywhere.. i can hear it.. but it still has zero problems..
i gotta disagree with you on the v6 weighing more then a I6.. if you check
www.mr2oc.com
there is someone on the forum who did the 5vz-fe swap.. and i have one in the garage gonna put it in a mr2 this summer woot.. anyways it weighs only 40lbs more then a stock 3sgte.. a 1mzfe v6 weighs less then a 3sgte.. the 2jz weighs alot..
that is why the le mans supra used the 3sgte.. saved alot of weight..
i think thats one of the biggest downfall of the 2jz.. its heavy
