1JZ-GTE vs. 2JZ-GTE

[MongolDrifter]

whats up guys
i have some questions. i'll be using the car for street/drifting.
1. 1jz-gte vs. 2jz-gte? both have 280ps, one is 2.5l and the other is 3.0l, both twin turbo... so which one has greater potential?
2. should i get a sx90 with a 4s-fe 120ps under $1k and swap the engine with 1jz-gte or 2jz-gte, or jzx90 tourer V with 1jz-gte 280ps, and if i get the jzx90 should i swap the engine with 2jz-gte? either one i get i have to have blow off valve, turbo timer, lsd, coilovers. so with all these mods which one would be cheaper?
thanks, any comment is appreciated

There really is no choice here: 2JZ

[LucidStrife]

As a rule of thumb the larger the displacement, the more power a motor will make. Now before I get flamed there are a few exceptions here. Forced induction is the main difference for that is the only replacement for displacement as far as i'm concerned. Now you can tune a smaller motor to make more power then a larger stock motor, but you are always limited by your displacement and boost. Some motors have been engineered better, such as better balancing, better valve train so on so forth, and these motors perform better and more efficently then others. But this is common sense so really its what you can afford, price out the motors and do some research and see what kind of after market parts you would need and how easy they would be to find. After weighing all the variables then you can make your choice. As far as your motor selection here the 2JZ is the better chioce for power, and parts avalability. I am not sure about the price difference and I wouldnt imagine the weight wouldnt be that different. Good luck on your decision.

spoken well!!!

i would prefer the 2jz...more power potential...Toyota LEARNED from the 1jz...there is no substiture for displacement in turbo applications...NONE. but the 1jz's are a rev happy motor thanks to the small 2.5 liter displacement vs. the 2js 3 liter...

go ahead and buy the 2j you wont regret the extra power potential

if i had the money it would be 2jz all the way....the 1jz parts are too rare for me

[svtxchinoy]

2Jz is definately a better choice.

[hatebbobbarker]

id only go for the 1jz if thats what the car has in japan.

[LexmarkX73]

go Top Secret style... RB26

[drfsupramk2]

I have to correct the guy that said that toyota learned from the one jay z actually it is a direct descendant of the m series motors. That being said in a context you are right basically the onejz is a prototype to the 2jz. I would say go 2jz if you could afford it due to the aftermarket support.Some staunch drfiters will say that you should swap in a even lighter engine but I and 2jz compared weight isn't really an issue between the two. Good luck

[ovenmittjustice]

one cool thing about the 1jz is the much shorter stroke, making it very rev-happy comapred to the 2j. Also, i believe, the 1j is parallel turbo while the 2j is in-line. from what i here, the 1jz makes quite a highway motor...

[ovenmittjustice]

oh yeah, and it is cheaper

[drfsupramk2]

True dat it is cheaper I like the 2jz because of the abudancy of easily available stateside performance options.whereas the 1jz has alot better perofmance options in japan but I guess it doesn't matter since we are not talking about the US. I wasn't aware of the onejz's higher revs,I personally prefer higher revs. I not sure what your saying about the turbo are you implying the 1jz has bi turbo compared to the 2jz's sequential setup.this thread has been very informative.

[hatebbobbarker]

the more important question is how much hp do you want to make?
if i did an rb240 id be fine at 400which is a waste of the motor in my opinion, and thats why i dont want to do it.

Swap the heads from a 1jz to a 2jz block. It takes advantage of the 1jz single turbo (later models) with variable valve timing

The 1jz also has ceramic turbos: Meaning if you turn up the boost anything 'good' over stock then they're gonna blow up on ya.

Mind you that the 2jz has the same CT12 ceramic turbo issue: if its the JDM version.

The best engine in the Japanese car world is the USDM Supra motor because it uses steel turbo set-up. Not sure why the JDM version had cheap *Censored**Censored**Censored* version. I think its the ONE time we got a better product vs its Japanese counterpart

theres a lot of debate over independent twin turbos (1JZ) and parallel setup (2jz) so you'll have to do your own research on that. ....

eh, Id dump the dual, single manifold on the 1jz and the twin turbo manifold on the 2jz and just get a big single turbo manifold fabbed up

This must be Tengis... How have you been?

uhhh arent they sequential on the jza80 supra, but an easy switch to parralel (just a few lines)

[ToyoTT]

As a 1jz driver myself, i can tell you that the differences between the 1jz and 2jz are very minimal, aside from the extra .5L a lot about these motors is the same. When you say, toyota corrected its mistake by creating the 2jz, that is wrong... toyota corrected its mistake of the 7m by creating the 1jz. Most of the engine parts from the 1jz are exactly the same as the 2jz ie. serpentine belt, headgasket, water pump.... there are many things similar about these engines... as well, some say the 1jz head flows better than the 2jz. Orin bivens from texas has put down 836rwhp with a 1.5jz, that is a 1jz head and the 2jz block. I like the 1jz, but i drive one,

[drfsupramk2]

corrected the 7m? Yeah I don't want to even go there. All I'll say is that I have expe. with these engines. People like us will probab;y never agree on this subject. I could list faults in your theories as you could list a few in mine however we will just run the thead into the ground.
By the way 800 hourse is nice but I've seen more from a 2jz. Please don't knock the 7mgte because I've seen these put out just as much hp as the 1jz's.. The 1jz is nice but I'd never rock it over a 2jz.But it's all about evolution But if evolution is what you suggest then why does the 7mgte evolve into a 1jz but the 2jz can't evolve from 1jz huh? your theories make no sense. I not trying to be rude. I have worked with just about all the m series engines. and yes the j series came from those. Read up on your toyota engine history it's all about evolution in a great design. Like I said I'm not trying to be rude but c'mon a 1jz over a 2jz no way!!!!!! the 1.5 maybe but not the 1.

[tonesdef86]

1jz's sound cool but all in all the most power will be had with a 2jz easily

[93180sxredtop]

theres no replacement for displacement

[DriftGirl]

There is no debate here: The 2JZ is a superior engine...period.

i agree too......those engines are really good.....

[tonesdef86]

ok the 7M i have seen blow up several times in a buddies supra and another corolla.


other than that the 1jz can not share a single internal part. A lot of motors and cars use the same external parts IE water pump and alternator just with differnt mounting points so the 1Jz and 2 jz are completely differnt motors.

[Bathurst R]

the 2JZ gets my vote

my question is why is this girl on point and you guys aren't. She knows whats up.
<-------------thinks she is probably sharter than most.
driftgirl props to you for having sense.my point is if you have the money for the 2jz then wheres the debate?
by the way any one blowing up good 7mgtes alot probably needs to learn a little more about engines. replace a few things incuding hg and these things can be bulletproof.
<-----------thinks if you keep blowing up 7mgte's means you are not doing something right, plain and simlpe. are you running over 500 hp with no real head mods?
sorry to be rude but I have to put it down. Realistically theres a great number of peeps with nice realiable high hp 7ms out there.These guys rarely blow engines because they are done right. one thing to consider is boost on a 24 valve head. these have troubles if done wrong over 500hp.

I heart you.
