1JZ>1.5JZ<2JZ Discussion

[OneJoeZee]

i know he is but who gives a fuck if its stroked or destroked it still a 7m

EXACTLY!!

How can you say that but be against my suggestion to keep the 3L 1J in the 1J section?

Why is it different for a 1J? Why does it matter if it's 2.5L or stroked 3L or not? It's still a 1JZ. A stroked 1JZ. That's all.

Who cares if I have a 2.5L or 3L block under my 1JZ? It's still a 1JZ.

 

[Supraboostin]

but they using the 2j block so is not a stroked 1j

 

[dbsupra90]

so if i put a 5m head on my 7m that would mean it should be in the 5m section?

 

[OneJoeZee]

It IS a stroked 1JZ. The 2J block itself is needed because of the deck height, not because it is inherently better for some reason.

The displacement difference is in the crank. Hypothetically, if I took a 3L crank and stuffed it in a 1J block, by your definition it would be a 1J.


You are contradicting yourself, especially considering your statement about the 5M crank 7M. You said it's still a 7M whether it's stroked or destroked.

Your viewpoint was better off before you said a 7M is still a 7M even if it has a 5M crank in it. You're flip flopping now.

 

[OneJoeZee]

Well, as to not contradict myself, I would say yes.

I'm glad you said that though along with Poodles bringing up Aaron's destroked 7M.

There are all kinds of GTE engines out there that could potentionally end up on the site. There's 1JZ, 1JZ with 2JZ block, 2JZ with 1JZ block, 2JZ, 7M, 7M with 5M crank, on and on. (assuming they're over 500hp.)

I think it's a good point in you bringing that 5m/7m up in showing that the 3 sections already on the site may not be sufficient later on in the future for the site.

Maybe, anything that isn't a straight 7M, 1JZ, or 2JZ should just be in it's own "other(or hybrid) engine" section.

First of all I read this thread thinking there would be some sort or reason to look into. After reading it though, your upset becuase of where you will get placed after an engine change...Wow.

But back to the topic at hand... The 1.5jz is a 2jz block with a 1jz head. If you took the car to have an emissions test done on the car, the tech would look at the engine block, see a 2jz stamp and go with that.

Plus, your in Cali right? If you aren't I was and there if you were going to make your swamp lagit (which you most likely won't) Your aren't going to tell them it's a 1jz becuase they would laugh at you, you wouldn't be smart to say you have a 2jz block with a 1jz head, becuase again that would be concidered incompliant with emissions. (You would if you want a lagit car) Say that you swapped a twin turbo supra 2jzgte motor into your car as a replacement.

This point really could be argued all day becuase really all your claiming is that if you were to take the head of a pig and put it on a horse, in your mind it would still be a pig...That's an interesting thought?

i think thats the best idea.

First of all, please show me where I said I was upset.

2nd, what an emissions tech would say is rather irrelevent to me as far as this conversation is concerned. What I would hypothetically tell the smog tech is equally irrelevent.

3rd, animals are irrelevent as well... Show me a hybrid pig headed horse or a horse headed pig and I'll think otherwise. The hybrid engines we're discussing are not make believe.

haha

pick a thought and stick with it.

 

[got_boosted]

I believe that it should be in its own class. It's not a stroker 1J because it's got the benifit of the taller deck height, and it's not a 2JZ because it's got a 1JZ head.

Who cares if I have a 2.5L or 3L block under my 1JZ? It's still a 1JZ.

A real stroked 1J, using a 1J block, an overbore, and a stroked crank, would be a COMPLETELY different engine than a 1.5JZ. There is no way to argue otherwise.

I moved this away from Duane's thread as I suspected things would get a little passionate

Having said that my take is the block denotes the engine family as it is the foundation of an engine.

Doesn't matter what internals or head that is on it if it's an xx block it's an xx motor.

 

[OneJoeZee]

In what way? I know there is a 1J stroker kit. It's a 2.8L I think.

edit: that was for gotboosted.


Ian: Opinion much respected. Agree to disagree is the phrase that comes to mind, though.

 

[bowsercake]

2JZ block + 1JZ head = still a 2JZ
1JZ + custom crank/rods/piston stroker kit to 3.0L = still a 1JZ

EDIT: about the deck height argument: the 1JZ does not NEED the extra deck height. It might need it to get to a certain displacement, but why does it have to have that certain displacement anyways?

 

[IJ.]

Do I need to unban Siman so he can explain it all to you guys :biglaugh:

 

[Kylar27]

One Joe,

hmm, the engine is the block, not the head. What if we had aftermarket heads available for our cars? "hypothetical" So if I bought edelbrock heads for my 7m it would no longer be a 7m it would be an edelbrock engine acording to your logic.

If you have a 2j block and you are using a 1j head, then guess what its a 2j engine with a 1j head... not that complicated.

 

[OneJoeZee]

That guy will only anger me with his "1JZ and 2JZ crank are the same" bullshit.

Exactly!! A felow logic user

LMAO he got me to the point where I slapped 10K on the table and was ready to hop a flight to the US

 

[got_boosted]

I agree with IJ in a sense that technically it's still 2JZ engine, but my originally claim still stands that it should not be lumped with the 1J's or 2J's but instead should be in its own class, as it has the benifits of the 3.0 2JZ bottom end while still having a 1JZ head. It's not a 1J or a real 2J.
