Has anyone done a 1UZ-FE MK2 Supra?
 

i have seen a 2JZ MK2 supra b4

but was wondering if anyone done a 1UZ.. i would think it would be so sweet..

A 1UZ? Is thatbthe same as the 1JZ?

no

its a Lexus LS400 engine

v8

i know of some guys who put it their MK4 supras

in a way its superior over the 2jz.. since a 1UZ is an overbuilt engine just like a 2jz.. it was used in the le mans MR2 car.. its cheap to find.. they go for anywhere 300-1000$.. i have a MR2 and my dream was to put a 1UZ in there but its way too much work.. so im putting in a 5vz-fe which handles boost VERY well.. its a wonderful engine

and now the the supras are using 3UZ.. but the 1UZ is superior to the 3UZ for boost purposes

it was voted one of the top ten engines of the year twice

Now I dont want to sound like an a$$, but I do know for a fact that usual v style motors are very complicated due to the balancing issue. When pushing over 550 hp on a v style motor the balancing becomes an issue and then renders thay setup useless unless you do forged goodies and blueprinting.

Also another thing to mention is the VQ 35 or the VK45 motors which happen to be V6 and V8 are both having the same issues. I can prove this to you cause I have a couple buddies that have these cars and motors. They should have kept the RB series instead of changing them to the V6 and V8.

Also do you have a link for this motor swap? I would love to see it. Thanks

a 60 degree twin blancer V6 is just as balanced as a I6

here's alot of info on the 1uz-fe

www.1uzfe.com

no offense to alot of supra guys with 2jz's.. but IMO a 1uz-fe is superior.. espacilly with the costs in voloved.. you can buy a 1uz-fe and still have like 4000$ extra to play around with over buying a 2jz used..

Maybe I am not looking in the right spot but your link didnt provide any balance specs whatsoever. Look, you can preach to me all you want about the similarities of balancing a v style to a inline style motor the fact still remains the inlins 6 has been able to put out more power more safely stock than the v style motors. For example, look at the 350z or even the gs 35 which are the same motor which is a vq35. Now you cant tell me for stock block to stock block that the vq35 is a better motor.

The 2jz stock can put out more than 800to the wheels without any problems. You can barely get a stock vq35 to hit 550 without having internal problems. If you dont beleive me I have the dsport mag and people who own the car to prove it. We can talk all day about these matters but what its going to come down to is what really works and what reality says to us.

I can show you a handful of supras that have reached the benchmark of 800rwhp on stock bottom ends. O the other hand, it would literaly be a challenge for me to find 1 350z or g35 or any other v6 for that matter that has reached that very same mark and works great on the stock bottom end.

Good point Skilmatic you right.

okee the I6 vs V shaped motors .. i think your very wrong on that.. people with mustangs can pump out 800rwhp easily with very little money.. its a V8 and they dont run into balancing issues..

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

oh noesssssss... are we having a small debate?? hehe

ya wanted to see 1uz... well here's one ;)
supercharged as well :p

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.

Wow whose is that? That looks pretty nice.

it's a friend of mine from here in NZ

it built it from the ground up really awesome ;)

NZ? New zealand? I didnt know they have supras there. You seriously live there? Do you have any pics? You must have seen lord of the rings people there.

lmfao

k

1. altho nz is small... we're not that small that we live next to the city that did lord of the rings LOL (no i haven't seen any of them lol)

2. of course we have supras!!!! haha.... check out my sig and you'll see my supra ;)

here in nz we get the japanese cars so rhd and all the options and digital dash that you wish you guys had ;) :p

Ok thanks for the tease. You are going to get spanked now haha. Well you have a nice supra. I am going to japan in about 2 years. There I will buy a 2000 twin turbo supra and when I return to the US I am getting the 07 R35. I have been saving for years for the supra and I will have enough money to get the R35 too.

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

i found this picture yesturday online

omg its a badass supra.. how much power is he pushing out of that thing? 400whp?

sweet car. where did you find it. whats the site to the page.

those two images are hosted on my website.. they are all i have on Ewans mk2

there may possibly be another site with them... which in that case post it up ;)
that mk2 lives about 3 hours away from me

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?

http://www.toyota-f1.com/public/en/s...oyota_car.html

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

http://kaferjca0.tripod.com/3sgteinfo.htm

another link

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...

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..

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

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 :p

lol i havent said anything personal or offencive..

you dont have to tell me that.. mr2oc is one of the strictest car forums out there on that kind of stuff..

Great, yet informative discussion. Learned alot. I do have a little input though. I think it is hard to compare V8 or V6 to I6. That is about like comparing apples to oranges to bananas. Many people prefer V configurations. Others I configurations. Cant we all just get along. They all have good points, especially if made by Toyota. Oh yeah, that is one sweet Supra! I am sure the owner is very proud. This has definately sparked my interest in the 1uz. As far as any engine is concerned, as long as you have $$, it can be made fast and dependable, that is of course, unless, it is my wifes kia(dont laugh).

Really? Because thei is what I said. Where do you get that from this down here? I would appreicate t if you didnt putwords in my mouth. Thank you


Why dont you just build your motor up instead of swapping?

OK we will play nice.

Thats the key right there.

?????

you just stated here that V style motors are very complicated..

and that is NOT the issue.. its just that the 2jz COMES with a built block.. i dont need to BLUEPRINT a 5vz-fe to get massive power out of it.. or a 1UZ-FE .. its done with just putting in forged goodies.. that HAS NOTHING to do with the style of motor.. its just wat was used on the buttom END

and again here

it has NOTHING to do with the fact its a V6.. its what kind of internals were used

leave out the style of motor arguement..

Again, you are misconstruing what I am saying. Any motor can put out any power as long as you have the money to do so. However, what I am saying is for stock block to stock block the cast iron inline blocks are the strongest and can put out more power stock than any v motor can due to the balancing issue. If you didnt touch any internals on a v6 and an inline 6 the inline 6 would be ableto produce more power much more efieciently and without fewer or any problems. If you do this to a v6 because its a v style motor the balancing on the stock bottom ends are usually only able to withstandup to 500whp. If you exceed that on a stock bottom end v6 you will have internal problems. On most cast iron inline 6's(usually refering to the 2jz's) those motors stock bottom ends can withstand up to 800whp fairly easily. Are you getting this now?

umm no your wrong.. cast iron 2uz-fe can put out 1500hp.. celica drag car..

your comparing a 2jz vs a 1uz?
then stop saying a inline 6 can do this more then V style motor.. if not i can name MANY inline 6 engines that cant withstand as much power as a stock 1uz-fe

again it has nothing to do with the fact its a INLINE 6... its just that its a 2JZ .. its built like a TANK in the buttom end.. if i had forged goodies on a 1uz-fe or a 2uz-fe or even a 5vz-fe it will make a better powerband

your missing out a big point here.. its not the fact its a cast iron block only.. lots of toyota engines are cast iron blocks.. and if you wanna talk plainly about block then a 3sgte can go up to 700whp before it cracks.. an engine thats 1/3 smaller then a 2jz..

the point again is that the 2jz comes with forged goodies.. thats it!.. it has NOTHING to do with the fact its a INLINE 6..
