2jz-gte jz gte powerful opponent

Toyota 2JZ It's powerful

We often associate it with RB26 as well as BMW Comparison

But Ford has one

You may not have heard of

In line six cylinder engine

Can compete 2JZ

This is it. Berra


 picture


2JZ Are you really dead ?


Of course not. , But here 1000 horse 2JZ Countless times , Lao Wu would like to introduce to you another niche straight six engine with great potential , It's not vulgar RB25/26, It's not a pure German BMW B/S family .


It's the Ford engine family that can't be found in the United States —— Barra.


 picture


Think about it. , know of Ford in-line six cylinder gasoline engine Do you ?


If you ask me this question , The first thing I thought of was the Mustang and... In the carburetor era F-Series The low configuration engine in the pickup , But this is because I am not familiar with Ford engines outside North America .


and Barra From the other hemisphere of the earth —— Australia / New Zealand , Today, let's take you to know this “ Tu'ao ” The engine .


 picture


Barra This engine family is actually divided into Inline-6 and V8 Two forms , We're just going to talk about 4.0 Straight six engine , incognizance Barra No problem , But I say one Barra You must have heard of your car , That's it For Ford in Australia Ford Falcon.


 picture


2002 year , Ford has launched a new... In Australia 4.0 Straight six engines and a new generation Falcon Four door car , Model code BA.( Yes , This is not really a Subaru lion )


 picture


Barra 4.0 The aluminum alloy head is equipped with double overhead camshaft , Each cylinder 4 Valves , And variable valve timing , These in 21 At the beginning of the century, American brands had very advanced technology .


 picture


Minimum power at the beginning of release Barra 4.0 The L naturally aspirated engine has 182kW(244hp), And with it Intercooled Turbocharged turbo Barra There is 240kW(322hp).


Over time, the power of the engine is also increasing , stay 2016 , launched in Falcon FG-X XR6 Sprint models , turbo 4.0 l Barra The final work of can output up to 325kW(436hp).

Why? 2JZ So popular ?


because Supra Mk4 It's a legend , But also because 2JZ Of Cast iron cylinder block Can withstand extremely high pressure , It is easy to replace the turbine in the original state 600hp I won't blow it up .


Barra The same is true of the cylinder block , The bearing capacity of power press is very high , And more than 2JZ many 1 Liter displacement .


 picture


There are many ways to squeeze power , Higher compression ratio / thermal efficiency 、 Higher speed 、 More intake pressure , But don't forget to increase the displacement itself . Dodge said something extremely red necked , One of the most famous is :“There’s no replacement for displancement( There is no substitute for displacement )”.


Red necked words are rough or not , There is truth in vernacular .


be relative to 3.0 Ascending 2JZ engine ,4.0 Ascending Barra stay The torque output at low speed is much larger , And the whole output curve is smoother , In other words, motivation comes much earlier .


 picture


Now many so-called car critics compare cars by throwing a lot of data to you , But they don't actually analyze these data themselves , Therefore, the public is very obsessed with the data of peak torque and maximum power , What the curve itself is often overlooked .


In fact, the power and torque in the middle and low speed range are very important for daily driving ,Barra It also shows great advantages here . Of course, you can refute me and say 2JZ If you install a smaller turbine , Low twist can also be excellent .


you 're right , But the loss of high turn output will not be worth the loss ?


This thing , When you grow up, you will make a lot of things easier , Many trade-offs can also be directly avoided .


 picture


But large displacement has its own problems ,3984cc The displacement makes this Barra The size of the engine is very large , And his weight is not small , This is supposed to be Barra The biggest problem .


Barra Compare... In size 2JZ Longer 、 Wider 、 Higher , You know, the straight six engine has been V6 and L4 One of the main reasons for machine replacement is length .


Than the same displacement V6 Engine chief 50% The above straight six engines make the new car Packaging It's very difficult. , How to plug such a long engine into the engine compartment , At the same time, maximizing the interior space is the main headache for the main engine factory .


Moreover, it is even more difficult for the straight six engine to be placed horizontally , After the engine was plugged in, there was no room for the gearbox .( Why did Land Rover put L6 I don't know if it's horizontal in the Freelander , But many things that Land Rover does are beyond the comprehension of normal people .)


 picture


Oversized engine size Let many lovers engine swap There's no way to choose when you're Barra, This is also 2JZ and RB One of the reasons why it is more popular .


Barra and 2JZ The nose is made of aluminum alloy , And they all have variable valves (if properly equipped), This can be While maintaining low speed efficiency and smoothness, the high speed output is smoother .


I know… I know… it’s no VTEC…


 picture


The hardware of both engines is very reliable , Using the original factory short block Under the circumstances Barra and 2JZ Can stabilize the output 600-700hp.


Everyone knows the routine of Toyota making cars , Reliability is the key , therefore 2JZ Original cylinder 、 connecting rod 、 piston 、 Crankshaft, etc. are very durable , And compared with Barra for ,2JZ The material cost of the cylinder block is higher , So although the displacement is small ,2JZ The potential is still so great .


 picture


Barra stay 600hp It's also very worry free , The original intra-abdominal hardware is enough , But horsepower goes up again , There are several things that must be upgraded .


 picture


From the bottom up , Due to the design of the oil pump , When the engine was under heavy load, the oil pipe became a victim , Install a... Here windage tray( Please tell me what this Chinese name is ) That's it .


Another is OPG The oil pump gear is , This thing seems to be a common weakness of Ford engine , stay 5.0 Coyote The engine must also be upgraded .


The crankshaft 、 piston 、 There's still nothing to worry about , In particular, the original factory has pressurized Barra The engine compression is relatively low , Not easy to explode . But under high pressurization , The cylinder head screw that connects the head to the cylinder block is a weak link , The original cylinder head screws may be “ Lengthen ”, Lead to a series of endless problems .


The last thing that needs to be upgraded is the valve spring , If it's a naturally aspirated engine, it should also Upgrade the valve itself .


 picture


So when it comes to the end 2JZ and Barra Which is better ? In fact, there is no good or bad , Each has its own advantages and disadvantages , Just choose one that suits you better .


 picture


High horsepower in North America 2JZ A lot of , Because it's easy to find 2JZ.


In Australia, high-powered Barra Everywhere you can see , Because the second-hand there Barra The engine is very cheap , And the refitting parts are also very easy to find .


In China, ,2JZ and Barra It's hard to find , So play EA888 and K20/K24 More . But now you know Barra engine , If I told you in China ¥15000 You can buy a car dismantling machine , Do you have a heart attack ?
