2jzgtte or 2jzgte

[triplblak13]

which is better: powerwise, swap issues, overall fab, and cost? all opinion but would like backup with write ups or facts please

Toyota NEVER used TT as the engine designation. 1 T -- we aren't freaking Nissan guys :D

That said, look at what the high HP MKIV's are running ---- Singles ... No write-up needed, just plain fact. Yeah, 2 turbos "could" make some serious power, but, there isn't enough exhaust on a 3.0 inline 6, to spool 2 large units.

[CJSREDPRA]

Wow...... Someone didn't do their homework....

2JZ-GTE: As much as I hate to say this.... Start reading the threads over at the SupraForums.

2JZ-GTTE: SHOW US PROOF THAT TOYOTA EVEN MADE ONE OF THESE. This would be what, 3, 4 turbo's?? (and someone, years ago, has done a 3 turbo setup in their MKIV).

Sorry to be an ass, but this poll fails.......

[triplblak13]

i thought they sold tt engines...ive looked and saw them...but i am a nissan owner but want a supra and a project so i wanna kill 2 birds with one stone. At that ive always wanted one and always knew they had huge power out of single turbo 2js...just didnt know

but then again what is this?^^

this is a 2j with a single ^^


if I'm wrong give me websites where there is crate motor 2js

[Junkie]

We don't have to - GIVE - you anything. Do your own homework. Yes, Toyota sold TWIN TURBO cars -- ie. MKIV's, they NEVER, used the TT designation for the engine code ... period. The link you posted, shows the seller is an idiot, that doesn't know Toyota's engine designation.

[triplblak13]

I thought so but sorry man I'm new, I want to learn more and I want a project....i don't know where to start and when you say give I'm just looking for help

[83restomod]

the 2JZ motors that your talking about came it 2 forms the GTE and the GE. one is twin turbo and one is non turbo. so a better question would be....

hi im looking to do a 2jz swap. i did some research and found a few sites with good info. i would like your opinions on both the GE and the GTE forms. are they both equally as challening or does one require more work (ie wiring, fabing ect) thanks.


the above would get u a little more assistance.


also saying your new and u want a projects tosses up red flags. if your new then u need to learn. to learn you need to search this forum cause their is crazy amounts of info here and whatever your dreaming up its most likely been done before and is documented.

[Pep]

Definitely do your research about these topics to save getting flamed.

[triplblak13]

I'm sorry I'm trying to learn more and I know it was an ignorant move to post this stuff but I was trying to get help and I too was confused as to why both were twin turbo.


Should i just get this thread deleted and repost a different better written intro?

[Lee_MA61]

I think some of those engine sellers get Nissan engine codes confused with Toyota's. As they do use the tt to symbolize twin turbo. or at least I'm pretty sure they did when I was checking the the various VG series engines.

that being said unless you know a little history about xJZ some wouldn't know that 1JZ-GTE did come as a single turbo.

I personally like Toyota's coding system.

triplblak13 Check in the 1JZ/2JZ - GE & GTE swaps (http://forums.celicasupra.com/forumdisplay.php?f=16) just spend some time looking at people's swap threads. I'm sure you'll see things in there that will help you answer questions.

welcome to the forum.

Later,
Leon

ah, I think we've chewed on the guy enough. I'm no expert on turbos, but I can throw an opinion out there for discussion.

Few will ever argue that a large single turbo makes more max power cheaper than a twin setup. If your after max power for a dragstip or dyno, single is best.
If you care more about things like "always being in boost," then here is where a true sequential twin setup starts looking good. The investment may be higher and the peak numbers may not be as high, but for a daily driver on the street and curvy county roads, I would rather have upgraded sequential twins.

[CJSREDPRA]

Shawn is right.. The guys that are running this website are major idiots... The motor descriptions are.... for a better word.... "something else". I'm sure (at least I'm hoping) that you were using these guys as a sample reference, but I'm pretty sure that right now, most everyone else on this forum is giving these guys a VERY good laugh right now!!


http://www.jdmenginedepot.com/jdm_en...Supra_2JZ-GTTE

Despite what you see in the descriptions, this IS a 2JZ-GTE. As others have already pointed out, Toyota uses only ONE "T" to describe their turbo motors. Twin turbo or single.... Still the same.


http://www.jdmenginedepot.com/jdm_en...a_2JZ-GTE_VVTi

Part of the product description for this lovely item is EVEN MORE SCARY!!! jdmenginedepot.com NEEDS TO SHOW ME/THE REST OF THE SUPRA COMMUNITY that a 2JZ-GTE VVti was even PRODUCED starting in the 1994 model year!!! Hate to say this, but I believe it was 98 & ONLY on the JDM spec MKIV's. MKIV TT's never got the VVti motor in North America & the only VVti motor that North America MKIV's ever got, was the 98 N/A, which had the 2JZ-GE VVti. I do know for sure that the 99 - 02 JDM MKIV's had the 2JZ-GTE VVti's.


this is a 2j with a single ^^

Are you sure??? From the way that turbo shield is shaped, it looks like a twin setup to me.... But just to be sure, I'm going to ask the Forum community anyway... Am hoping the hive collective will know this.

My question: "Are the 98 - 02 2JZ-GTE VVti motors twin turbo setups, or singles"??? I always thought they were still twins from the Toyota factory.

Reason for my oddball question:

Most of us know that 1JZ-GTE's came as non-sequential twins stock from the factory, but when the 1JZ-GTE VVti came out, it came w/ a big single from the factory & they did away w/ the twins.

2JZ-GTE VVT-i Twin, only the 1JZ-GTE VVT-i came single of the JZ series. :)

[CJSREDPRA]

Sweet!!! That's what I thought. Thanks Leon!!!!

<---- Freakin HyperRev Issue #3 does not show enough pictures of any stock 2JZ-GTE VVti's....

[Lee_MA61]

No problem Chris.

The VVT-i GTE is a very interesting little engine. I'd really like to get my hands on one of them just for the fun of a stock smooth power band. not the the non VVT-i's are not smooth but the VVT-i's are supposed to have a nice flat/smooth powerband much earlier than the non.

[lacrssgus14]

Yeah, 2 turbos "could" make some serious power, but, there isn't enough exhaust on a 3.0 inline 6, to spool 2 large units.

Shawn just because I am an ass.

Twin 61mm's.


So far we made 675 rwhp at 19 psi, 19 psi and 300 rwhp by 4000 rpm

I'm trying to find the dyno graph to extend my ass-ness, lol.

[Junkie]

Brian, serious power isn't 675, and I garuantee, that engine is laggy as hell. 19psi at 4k, is great, turn it up to 25psi, and tell me what RPM it hits full boost ;) Stu Hagen "local MKIV owner", is pushing or just over, 600 on upgraded "stock" twins. His car is pretty smooth, but, still doesn't compete with - serious - power cars. IIRC it isn't enough for 10's, and if it is, just barely.

2 x t61's, should be well over 1000hp in the 25psi range. But, the isn't enough energy in the exhaust, to spool both of them quickly. That car will be a drag only car, and need a 2 step, and/or spray, to be effective at all, more than likely, it will need both. I'd race it, with a 600hp 7mgte. But, that's bench racing, will never happen, and better yet, I'll probably never build a car with that power.

Fact of the matter is, for big power, a big single, will out perform twins, 99.9&#37; of the time. If I was wrong, Titan, Boost Logic, Sound Performance, etc. would be running twins on EVERY build.

[Lee_MA61]

That and it's pure physics why a singles are better than twins.

[lacrssgus14]

Shawn, I was hasty with this since the kit is not complete yet, they are waiting on the new ProEFI standalone system to push it higher. Also it is a full sequential kit spooling the first turbo to about the 4000rpm mark. The 2nd turbo was just coming online when it made the 675. I do have a dyno graph with this kit overlaid on a GT-42 at 27 psi.

This is the next bing thing for the MKIV's, but is still in development. As far as none of the big shops running twins, why when you can just shell out huge amounts of cash to anti-lag a $4k ball bearing turbo and feed it a 300 shot of Nitrous. I'm not saying its better, I'm saying its possible.

[Junkie]

Brian, got ya, and totaly understand. I still won't belive it's "the next step for mkiv's" as they will still have to spend the big bucks for anti-lag, and spray, to reach the #'s the Ryan Woon, SW, and company are making, and be consistant.

SW just pulled off a 241.8mph standing mile, on a big single. He, of all people, has the cash, to make twins work that well, if it were possible. I don't see twins on that car. Call me when that changes :D Ask the Viper guys ;) that he spanked --- BAD --- at the Texas Mile ...

[Donn29]

In my minds eye it the complexity, cost(a relative term) and the fact that twins aren't what people are 'doing' now. 1 or 2 people are going to go with big twins and then everyone will start talking about it.

There really isn't enough room to do a big twin setup though, on a V8,10,12 its simpler to do twins.
