to 1j or to 2j that is the question
I am trying to decide whice engine to get. Should I go for a 1jz, 2jz or a 1.5jz. the 1j would be the cheepest and easiest to do the 2jz is nice but a lot more in price and how many times would I be able to use the true potential of the motor ( Top End). And the 1.5jz I was told would be the better of the three having the torque of a 2jz and high reviing ability of the 1jz.

someone answer the torque question.... i was always under the impression the 2jz comes out on top in this area
P.S. - i don't know if this matters to you or not.... but the 1jz with exhaust just sounds gawdly amazing.... i'd almost get it for that sole reason

As far as the torque curve, I would assume what turbo/turbos you are running and boost levels would affect that. Laggy turbos will make less torque. Bigger displacement will always make more tq.
On another note, why would you get a 1JZ anyways. I don't get it. It's like the 240sx guys getting SR20DET's. Okay.......... Let's downsize on the current displacement we have.
Sure the turbo/s are already there, but now you have an engine with less potential than the one you had before.
I'd either turbo the 3.0 GE, or get the GTE if you're gonna do anything with turboing your car. 3.0L will be better than 2.5L in the long run.
Just my .02

Is that intended towards me? If so, I guess I wouldn't want to do any researching on the 1JZ anyways because I don't care for it. Speaking of tq curves, VTEC hondas have beautiful torque curves(though they lack tq itself) but they also have awesome heads and great cams. Does the 1JZ have some crazy good cams and a good head compared to the 2JZ?

lol.. 2jz cams have 1 degree lift more than 2jz's which isnt even that much... 1jz heads flow better and the 1jz curve is still better. I dont see how a subject on 1jz and 2jz got carried over to vtec's, and sr20's.. For more technical info go read up on supraforums.com

this wasn't ment to start a war which one was a better motor, both the 1j and the 2j are great motors. probably some of the best motors built. There is no way for you to compare a sr2odet or a vtec motor to a 1j a 1j is superior in all areas. By the way if u didn't know the 1j is the motor that came in the sc300 aka the soarer originally in japan. so why wouldn't u want to put the 1j in a sc300. I just wanted to get peoples suggestions of what they would think would be a better swap.

It wasn't a comparison of the 1 or 2jz to the VTEC or Sr20 motors. As for your comment about the 1JZ being superior in every way to a VTEC motor, false statement. But that's not the subject. Those analogies were just used as references. And to answer your question as to why you'd NOT want a 1JZ in a SC300? Um.. I already said why, displacement unless you feel the need to be "JDM" or can get a 1jz with everything for cheaper than dirt. Why downgrade in displacement? No offense to 1JZ owners and no I am not trying to start a war.
My suggestion would be 2JZGTE if you feel the need to do a swap.

I do under stand what u mean about the vtec motors I do know that the b18c type r motor and the b16a and b16b produce the most horsepower per liter but thats a diffrent story but line up a 1j and a type r and we all know who would win. Like I said no comparrison. Thanks for the suggestion

That's not what I was referring to, I could care less about hp/liter. VTEC heads are great. I know the GTE head flows like crap, and I'm unsure about the 1JZ but I'm 99% sure a VTEC head flows better in comparison. Either way, 2jz gte.
