I was just wondering why so many people like the 1J better than the 2J motor. It's half a liter smaller, so why would it be better? Thanks.

The ability to rev it higher then the 2j is a plus, also the cost of the 2j's over the 1j, even though they aren't much more.

How do the redlines compare? Or the real-world safe-revving rpms rather.

easy wiring the 1j,2j supra ecu is a pain
1j is alot cheaper then usdm 2j,aristo motor needs different oil pan
more part's have to be sourced for 2j,1j motor mount's and bellhousing
deffinatly a cost factor
if you pull the abs line's out of the way,the 2j with twin's fit's.the rear turbo charge pipe will be up against the firewall

In the real world where a real modded 2j vs a real modded 1j the 1j gets its ass handed to it every time. This is a joke right! Not even believing a 1j can spank a 2j unless the 2j is bpu.:naughty: :biglaugh: :nono:

Hey Quikstrike......this isn't Supraforums so you can chill out with all the name calling. Can you not make a point without trying to embarass or ridicule someone. If you're so smart, quit trying to make everyone else seem stupid and just answer their questions.


Not trying to make people feel stupid at all. However; in a forum if you pass on nonsense rediculuous answers it needs to be set straight. Forgive me for reading the cluless responses and wodering WTF. Supraforums has nothing to do with it. As a matter of fact IJ is over there.;)lol Noise volume of clueless answers some time sets me off.:nono: If I offend you I am sorry! Post facts not opinions. Go read the post dealing with old timers. I was here WAY before many of you, and left after the forum collasped. I will TRY to make it as you asked.:biglaugh: So allof you ass's that I called an ass I appologize

I don't think you'll find many people who are willing to seriously debate that the 1J is better. Anyone who purchased a Mk3 shell and intended to install a built engine, big snail, standalone, and supporting mods right out of the gate would likely buy a 2J - at that level, the cost difference will be such a small fraction that it wouldn't be worth worrying about.

Furthermore, I know a fair number of people who have gone 7M -> 1J -> 2J... I don't know anyone who has gone 2J -> *anything*.

Just because you like the 2j more, doesn't mean you need to be rude to the 1j fans.

For the record, the 2j twins fit just fine, no mods needed to the body, other then hammer a little dent to give a little firewall clearance.

I'm pretty sure the free motor influnced your (in)decision mike.

Anyhow, I got a car with an empty engine bay. I bought a 1j. Why? I've had 7m's, 4 of them to be exact. I wanted to try something new. Also, it could be a stepping stone. With the 1j parts the 2j is pretty much plug and play. Also, it's a cheaper, simpler swap than going straight to the 2j. With an empty engine bay it's almost on par with what it would have cost to buy all the 7m parts to fill it and have the engine rebuilt anyhow.

I'll debate that. I'll tell you from installing and selling whole lot of engines, you will have a MUCH better chance of getting a JDM 1jz with good compression (like new), minimal carbon buildup, and minimal cylinder wall wear.

Debate the 1jz is better? I wouldn't say that because the design is almost exactly the same. Better for installation ease, and cost...yes. Better turbos on the 2jz....no. Same chance of getting bad stock turbos on a 1jz or 2jz.

The actual sound of the 1jz with a nice downpipe and catback is awesome if you ask me.

Long term use, like 150k miles+ of hard driving at elevated power levels....1jz ftw.

Stock turbos fun to drive...1jz ftw.

Mr.PFloyd
01-17-2007, 01:04 AM
ill add another point. Some people just don't care as long as they get out of the 7m. My brother had bad luck with 2 7m's said fuck it and went 1jz. He could have went 2jz but he didnt because like most of us, there isn't much more you can do with the 2jz as opposed to the 1jz because the power levels half of us are shooting for are very well within a singled 1jz whereas a 2jz would be the same story, just more money. Just sayin.

1j's WHERE cheaper... but 2jz's prices have dropped like stones after the aristos have been gutted....

And the fact that you need lots of bits form a 1jz swap to put the 2jz in.

other then that... 2JZ FTW

.5 displace ment is good no matter how you look at it.

If they sold a 3.5 I6 or 4L I6 that was just a stroked form the factory JZ engine. I'd say that's the engine for me.

More displacement = more fun = no reving to the sky to spool that huge turbo = more fun for the stree = :)

"If they sold a 3.5 I6 or 4L I6 that was just a stroked form the factory JZ engine. I'd say that's the engine for me."

I couldn't agree more.. There is no way that I would spend extra money for a used engine with less displacement. And there is no way I would spend lots more money on a used engine with equal displacement. However, if there was a 3.5 liter "3JZ-GTE" motor, I would be the first in line to purchase it.

Its not so much that everyone prefers the 1J over the 2J

my choice of the 1J is for a few reasons,

-it is made to fit in our cars
-it is much easier to install for a novice (such as my self)
-requires less wiring work to make it work
-cost less money to put together and have a running 1J car
-the 1J revs higher which is good for certain types of driving/racing like Drifting or Time attack or lapping
-there is some nifty factor to it
-the 2J just has to much hype surrounding it still which demands a premium price for everything you do with it.

I like the power stats it is capeable of on its own merrits. The 1j is inferior to the 2j period. Installing a 2j isnt that complicated if you get a standalone other than an AEM. The problem is everyone wants a cheap drop in solution. Don't say getting a complete 2jz is cheaper than dropping a 2jz and a wolf, or a Haltech computer to run it either. The 7m crowd is usually younger guys looking for cheap bang for the buck mods. This will not yield an ultimate street car with reliable power.There is no debate that out of the box a 1J maybe easier, and cheaper to install, but that is it periodl. This is not meant to discredit the 1j or slap 1j owners as you imply. It is merely a fact proven by the 2jz motor all on its own merrits!

Ahem... OPINION, and opinions don't get PROVEN, however widely held and rational they are.
I can say a piece of granite is 'superior' to a 2JZ-GTE and not be incorrect, because it's subjective. If you want to say something specific like the 2J has more power potential than the 1J or whatever, have at it.
Meanwhile, everyone's welcome to make up there own minds about what's superior, and they can do it based on whatever they want: the way the valve covers and manifolds look in their engine bay, the cost effectiveness, efficiency, how much it hurts when you drop it on someone, etc

As far as i have seen the 1J has proven to be a reliable engine.

I went with a 1J yes due to cost and other factors. You don't have to be young and poor to not want to spend crazy amount of money on your car. being reasonable and understanding what you want to do with the car, making the best coarse of action is just good planning. You don't have to buy the biggest badest most expensive engine there is to get a good street car. You need to understand what your goals are and what you expect from your car, and to understand what it will take to get that.

When all considered and what my goals are for "my" idea of a great street machine. The 1J was the way to go. Ya it might not have 1000RWHP or be able to dyno 1200RWHP but i want something that is enjoyable on the street in all respects. Not that the 2J is not enjoyable, but for my power goals and other ideas of the car and how it should be the 1J was the right choice for me.

It is not inferior, it is just a different choice. Taking the attitude that bigger is always better. Then i submit to you, that people should be 400lbs fat blobs driving there car cause bigger is always better.

:biglaugh: You are so out there. How come every Toyota or Lexus drift car I've ever seen has a 1jz in it? You are saying the 2jz is superior because of horsepower potential alone, but on an overall engine performance level I have to say you are mistaken.

And you are also mistaken about the 2jz being cheaper to drop in with a standalone then a new mk4 harness and the jdm ecu from the Aristo clip. I don't know where you are getting your info from on that. 1jz is soooooo much easier to install in an mk3, you are making light of the 2jz install to serve your own arguement.

there is no such thing as a universially best motor, only one that is best for someone. if someone wants to drag all the time, they might think a LS7 with twin gt42rs is best for them, but the guy who likes autox might want a 2jz-ge with intake, headers, tune and exhaust.

im sure the 1jz has JUST as much potential as the 2jz, but lets face it. The consumer crowd that is purchasing the 1jz motors are buying them because of the cost. That is why you wont see any 1000 rwhp 1jz's.

I myself, prefer the 2jz over the 1jz because of visual asthetics and parts MADE for the 2jz. People say there are many parts for the 1jz, but lets face it.. most are rare and expensive and come from Japan. did i mention it is definantly more visually appealing? :biglaugh: I would pay the extra just for the looks alone.

Let me put on my flame suit ..... If we took a 1jz and bolted on a gt35r would it create the same power as a the 2jz? 2.5 liters vs 3.0 liters? I could be hella wrong but i dont think they have the same potential.

The way i think of it is 2.5 liters of air and fuel will never be the same as 3.0liters of air and fuel keep in mind the motors are very similar. To put it simply power is the amount of air and fuel going into the engine with good spark and going out.

Feel free to correct me and hey quickstike i am on ur side :) but its not what you say its how you say it

01-17-2007, 04:02 PM
The way I see it, the 1jz is actually a stronger platform.
Forget the 2j nutswinging for just a sec while you read this:

So you have two engines with the same size main and rod bearings, and the same diameter cams. Now on one engine you make the rods longer, the crank journals further apart for more stroke, and the deck taller. Isn't that going to make it physically weaker in terms of maximum hp per liter? You also have higher piston speeds at any given rpm, and the pistons/rings also travel more distance per crank revolution (read:more wear). The only way the 2jz would be proportionately stronger is if the dimensions of all the engine internals were increased.
Remember, the 1jz was first, and then Toyota decided to make an engine with more displacement to keep up with the hp output of other manufacturers engines. The only other way would have been more boost on the 1j, but that was obviously not an option for a production engine already at ~12psi stock.

For this reason, I argue, the 1jz is better from an overall strength and longevity standpoint at the hp levels most peoples engines will be at.

The 1jz,to me, is closer to the optimum piston engine design. When I think optimum engine design, I also think rb26.


I invite any well thought out arguements to this.

You guys missed the boat with the 2jzGE-T swap. If you are going big single it is cheaper and has more potential than the 1j or 7M.

Yes very same in setup ... I remember watching a clip of a modded 2jz and rb and the guy was saying how the skyline felt faster b/c of the way it rev-ed through the gears and how responsive the rb was compared to the 2jz

Are there allot more highly modded 2js then 1js? alltogether?

Sure in the US, because they came in cars that are now selling for $25,000+ that are up to 14 years old, so for the most part 2jz's are owned by people with lots of money to spend, or people who rack up lots of credit debt. Either way, those are the people who are likely to drop big money into their engine.

I was just wondering why so many people like the 1J better than the 2J motor. It's half a liter smaller, so why would it be better? Thanks.

It's not a preference, it's an issue of cost and ease of swap. If a 2JZ was as easy to swap in as a 1JZ and cost the same, no one would be running 1Js.

01-17-2007, 10:38 PM
lol.. Man, its hard to find the good posts in this thread.. there are a few though.

There are many reasons to run a 1J over a 2J.. But none of them have to do with strength or power potential. The 2J is equal to the 1J in strength, and exceeds the 1J in power potential.

The reasons ppl choose the 1J should be crystal clear! Money & plug & play! Although the 2J is a pretty straight forward swap, it does take a little more knowledge to execute it properly.. Even then most guys end up running 1J electronics! lol

The displacement argument has invaded this forum and SF over the past few years and it is just plain DUMB!!! Why? Well think about it.. The reason we say "Technology, the only replacement for displacement" is because of all the domestic pushrod guys making 350whp with 383 cubic inches.. lol YES the 2J has more potential to make power 100% based on its DISPLACEMENT, .5L larger than the 1J.. WHY? Because it shares the EXACT SAME TECHNOLOGY!! And I am not just talking about COP and ECU's here.. Technology to me is the entire design of the engine. So yea.. if you could build a 3.8, 4.0, whatever JZ and it retained the same engine dynamics, the power potential would just keep going up along with displacement and boost.. Well, until the rods got so long they snapped under thier own weight.. lol

i've rode in a 67mm 1J and a stock twin'd 1J

the stock twin'd was ALOT more fun than the big single. took too long to build boost and it can't get out of its own way when its not in boost...

plus there is no replacement for displacement..... why do you think the 2J guys are going to 3.4 liters now?????

Prove me wrong! Don't say 2jz or 7m parts that FIT on the 1jz. I believe there is not a HUGE aftermarket support for the 1jz as there is for the 2jz. Is there huge selections of down pipes, turbo manifolds, intake manifolds *SPECIFICALLY* for the 1jz? I don't see many.

Then theres the Ebay AND the Australian y-pipe

There are at least 4 different turbo manifolds readily available, for t3 and t4 turbos.

Intake manifold? Why? It already has a ffi, and if you really want custom them you just make a phone call and order one.

I have complete gasket kits, Greddy timing belts, 2 different power steering hoses, hydrofan hoses will be ready next week, I will make harness jumpers if you send the connectors (not possible for a 2jz swap), catback is the same as 7m.

There is PLENTY of aftermarket support for the 1jz.

Why don't you do some better research before being so sure about your assumptions of the 1J aftermarket since you're so experienced with the engine. oh wait, you don't even have one. Aaron just did the research for you.

Aaron and jose just made a whole freaking turbo kit for suprahero with a GT35R. MTR and MVP have fuel systems for the 1J for the higher power applications. Driftmotion is working on a standalone. ebay has parts all the time. the FS section also has 1J parts (more SF than here). there's spare 1J engines galore in the US should you need one. What else do you need that's so hard and difficult to find?

sure, the 2J has more aftermarket parts. but that was not the point of your arguement. You were implying 1J parts are hard to find and many have to be sourced from Japan which just isn't true. 2J has more aftermarket than a 7M as well.

never once did I say I thought i was better than you because you don't have one. so don't pull that card. thread doesn't need to be locked again so don't start with that. no one here with a 1j said anything of the sort. I brought it up because someone with a 1J would most likely know more about it than someoen who doesn't have one. I don't know a ton of info about the maf-t pros the 7M guys are using now. When that came about as more mainstream I already ditched mine. It doesn't really concern me that much so I don't know a whole lot about it other than the basics. Same as you don't have a 1J. Apparently it doesn't concern you enough to research what's really available for it.

Front facing manifold does mean more CFM, it only means shorter intercooler piping. You need a larger plenum and shorter runners to increase CFM. And that will decrease intake velocity and low end grunt.

Of coure, the effect is not as dramatic as when you do it on a naturally aspirated engine.

LS7's are sex! I heard that the General is coming out with a Corvette SS with a Supercharged LS7. 600 Ponies!! I guess they are testing it out because the '08 Vipers are coming out with 600 HP. But back to the topic at hand.. I guess it depends on where I lived as to which engine I prefered, here in Japan, the 1JZ both hands down! In the States I'd probably just stick with 7M-GTE. I say this because 1: I am to lazy to swap the engine. 2: The amount of hp the 1JZ put's out(280 HP I believe) vs. the 7M's 240 or so hp, isn't to me anyways, worth the dollar amount that it would cost to buy the 1J and then have it swapped in. There is only like a 40 hp or so difference between the two engines.

bigaaron
01-19-2007, 10:53 AM
Stock for stock, both with only an upgraded exhaust, the 1jz makes almost 100 WHP more then a 7m-gte.

The difference is that the 7m-gte, rated at 227hp, makes about 200-210 whp with an exhaust.

The 1jz, on the other hand, makes about 280hp at the wheels with an exhaust. We've had a few that made as high as 300 whp.

Now people say "well you can just turn up the boost on the 7m and make 300whp", but I can tell you from much experience, that a 300whp 1jz will run circles around a 300whp 7m. Not to mention that the 1jz would outlast that 300whp 7m in any type of endurance test.

I wasn't considering the elbow as a basic exhaust upgrade, but then if you change the elbow, it would only be fair to put a y-pipe on the 1jz, and it could make closer to 330whp in that case, from what I hear. I haven't dyno'd a 1jz with a y-pipe upgrade yet myself.
