We all know the 2JZ-GTE was and will always be a great motor, but will you please stop stroking it all over the forums. There are a few advantages the VQ has over the 2JZ you know. You cant be the best at everything, right?

 

I beg to differ. You have to completely build the crap out of the VQ to compete with a stock 2JZ-GTE. Sorry the toyota built motor doesnt have head lift at hight boost, plus its internals are built for perfection.

 

I'm not stroking anything, I love the VQ as much as the next guy. But the bottom line is, the VQ wasn't meant for boost but the 2jz-gte and the rb26dett were.

 

I am in the "huge waste of money" camp. Sure would make a neat car, and could servve to display the engineering and fabrication capabilities of shop. But other than that...I see no need for it. People are making similar pump gas power numbers with the forged VQ35's, and building a 2JZ is certainly not a cheap proposal.

 

If you cant even search Id hate to see you try this swap---> https://my350z.com/forum/engine-and-drivetrain/216282-supra-2jz-gte-swap-into-350z.html

 

The 2JZ is a great motor and has definately proven itself.

IMO(I've also discussed this with others this past week) The VQ35 is a great motor as well but costs are probably much higher than a 2JZ as far as parts and building it into a powerhog goes(VQ will require sleeves, newly released expensive forged components). Nobody dares to boost higher than 20psi(even with sleeves) with a 700+ efficient turbocharger on the VQ. The options are not there..

So is the VQ a better motor? Maybe.. But to say so is jumping to an overall analysis without venturing that territory.

 

Many have boosted past 20psi, its just that to make good power at that level race gas is needed in most instances, so its not a common occurance.

I hate these threads, you cant compare an NA motor to a Boosted factory motor. More fair would be built vs built, and in the 4 years the VQ35 has been in the Z, it has proven itself. We already have a VQ running 1300+whp and in the 6's down the 1/4. Didnt take us long to catch up to the 2JZ leaders did it?

 

Max HP potential doesnt qualify quality in an engine. So your arguement is the 2JZ is better suited to handle high HP. I can agree with you there. But I think thats about the only way the 2JZ wins.

 

I think its gonna cost ALOTTTT of money, and for that you might as well build the motor for 800whp and youll have a beast with a nissan motor. Honestly its not the motor thats the problem, its the little things that are gonna start to get pricey like a/c placement for one. If you think you can for less money then building the Z motor then go head. I just think youll spend LESS and WAY WAY less of a headache on building the Z motor for high hp. Call up Roger at japtrix and ask him for a recommendation on a motor internals. They know theyre stuff.

 

I was comparing a VQ with bolt-ons to a 2JZ with bolt-ons. Its pretty obvious if you build a block you can exert more power out of it if the bore and stroke is larger than another engine, 3.5>3.0.

But if you bolt on a tt kit on a VQ and a 2JZ the winner will be the 2JZ. The VQ will blow faster than you can say "pop". Supras have gone over 1000whp on stock block, I believe thats quite an achievement.

Don't get me wrong, i'm not saying the VQ sucks. It's a great motor, especially with the torque numbers it produces. But when it comes down to forced induction and bolt-ons, you cannot mess with the power of the 2jz. Those bastards never blow.

P.S. RB26DETT also is one of the greatest motors built because of its high hp & high rpm capabilities.

To answer the original post, I think its worth it if you are not going to pay for any labor.

 

Again with the stroking...

The 2JZ is not magic nor is it the god of motors! Take a look at the BMW S52 found in the M coupe and E36 M3's. They can make 900 rwhp on a stock block too... and they were never designed to take boost from the factory.

 

I've never seen a stock block S52 motor with anything close to 900whp. Those motors have too high of a compression to make 900whp on stock block especially with stock head gasket.

 

Stop Being a Pathetic Loser and get a 2JZ!

 

Looks like someone may like the 2JZ a little too much


I KID, I KID!

 

hahaha

I have experience with both motors, and that is my opinion. I don't care if people don't agree with me. I'm not badmouthing the VQ, but honestly they are completely different powerplants. The 2jz is made for boost the VQ isn't in "STOCK" form.

 

that's rite

 

I just got a moded engin it has 5000 km only on it and when i asked y he is selling it he said he is replacing it with a moded supra 1 on his z and he had another 1 as well for sale coz his friend had already done it. the only reason they do it is that they will have an iron block and not an alaminume 1 so they can easily boost it up add to that he can go up to nearly 600 whp on stock engin internals... BUT I DONT CARE I STILL LOVE MY Z :-)

 

WOW, i honostly dont know what it would feel like to drive in a 1300 whp car..thats a thousand more than what i have...whats the 0-60 on those? .5?? i kid i kid but really...

 

Way to explain the obvious.

But really, who cares about stock? We're talking about modified cars here.

 

The VQ35HR will change that, IMHO. 500whp+ stock Z's will be mainstream. 500whp will become the new 400whp.
