Has anyone done a 1UZ-FE MK2 Supra?

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

Again look at the dynamics and the kenetics of the 2 different styles of motors. Physics in its own tels you that balancing a v motor is much more difficult than a inline. I said a v8 can make more power because of its displacement but just like a v6 it wil have troubles on the stock internals when exceeding over 500hp. If you dont beleive me go and ask any ford or GM dealership . The reason why the 2jz is so heavy is cause its a cast iron block. But most v6 and v8 are cast iron too. Also do you have a link for this le mans supra?

thats the link .. scroll down and the castrol supra is a 3sgte

alot of the v8's from GM is pushing out 1000whp.. if you look at all the drag races .. street class.. mustangs that are doing 7 seconds are using v8's.. they are destroying supras.. im sure you can find them all over google.. look for outlaw mustangs..

a 5vz-fe is a 3.4 litre cast iron block v6 .. it weighs less then a 2jz for sure..

im not here to debate if a 2jz is a bad engine.. i think its one of the best I6's out there for getting monster power.. but saying a V6 or V8 cant be made to put out more hp then I6 i think is a serious misconception

the celica drag car utilizes a 1uz-2uz v8 combo pushing out 1500hp.. its on that 1uzfe.com site...

Again I am not here to debate that v8 or v6 can produce alot of power. I am saying they cant on the stock bottom end. My friends shop mustang is twin turboes and is putting out mroe than 2000whp. So I have no doubt that v8's can put out alot of power

heheh... nice debate up on here...

just so everyone knows im not here to cause any trouble!!! im new here and not the type of guy to pick fights!!! i love supras and all toyotas =D

[suprra_girl]

well... it was a "heated" discussion but not a total disaster hence i left it to roll on


but mind you... i will use a ban stick if ppl get too naughty

well you stated that a v6 or any v shaped motor is not gonna produce power .. that is the impression im getting from your statements..

just the fact the 2jz has a super buttom end dosent mean it has anything to do with its a I6.. it just has a super duper strong buttom end and i agree.. forged everything.. iron cast block.. built like a tank.. it can produce sooo much power..

well a 2jz is out of the question for my project.. there is NO way im gonna get that engine in the MR2.. without some serious frame and body modifications..
