Has anyone done a 1UZ-FE MK2 Supra?

the I6 idea of better balancing is not the issue why the 2jz makes monster power relatively easily.. its the whole design of the engine plus the materials used.. forged pistons+rods on a iron cast buttom end.. all toyotas engines have insane crankshafts..

800whp on a stock engine?.. i would think you would have to change the cams to do that.. plus thats on race fuel..


there are daily driven 500whp on street gas 1uz-fe's out there.. 14-15PSI.. stock engine.. its not the buttom end that has the issue with any toyota engines.. alot of them are built like a tank.. vz, jz, uz.. even the 3sgte has a very strong buttom end.. pumping out 400whp on a 2 litre I4 on street gas.. its been done..

oh and here's an article about balancing of a I6 and V6

Again your argument is once again flawed. You cant equivocate a 8cylinder motor to a 6 cylinder one. I am talking about v6/I6. Not V8/I6. And I know all about the V8 as my dad has a mustang GT. 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.
