How does a motor that's 2x as long, sit further back than the VQ? You mean you can put the front 3 cylinders further back in the engine bay than the front of the VQ? Unless you put the engine right in the middle of the car, I'm not too sure how you can really not be concerned about an extra 300-400lbs or so.

Plus won't the big single be top mounted? Those are exactly light. Plus the whole top end of the VQ is also aluminin.

 

Pretty much everything I posted in my other post. As well, the G35 that was featured in Turbo Magazine that was done by JE has reportedly has some issues. You have to run a standalone for the engine, and let the Z CAN bus run the ABS, VDC, Emissions, etc. which is a wiring nightmare. Also, if you want a water pump or anything that they don't really make aftermarket, you are looking at waiting a while for it. You also have to get a new cross-member I believe, as well as custom made motor mounts, although I think both of those come with the JE Import kits(not sure how much that runs though). In the end it just seemed like it would be more of a hassle than it was worth. Unless you are looking for the 800 or 900+whp then the VQ will be able to satisfy your needs w/o as much of a headache(when you go into 500+whp, you will have a headache or two no matter what engine/car). That is why, if you wanted to get something unique and can handle all the power you want to throw at it, you might as well do a 2JZ swap. You need a water pump, call Toyota or whoever carries stock parts here in America and you have one in under a week, rather than 2 weeks or more with an RB. As well, with a 2JZ, you can go to 800whp without touching the internals whereas the RB(if I remember correctly) has to have new internals after 450whp or so, and the stock turbos go out around 400whp.

 

2JZ = Powerhouse
RB26 = High Revving

 

right but usually lacks down low and sometimes in the middle and in order to get to that kind of power, you really need to stress the engine which is one of the reasons I went with a turbosystem rather than a centrifugal SC.

 

I think its rather amusing the comparison of an 18 year old engine to an engine which is 7 years old at the most.

I honestly believe that when aftermarket manufacturers and tuners have more experience under their belt technological advances such as Variable Valve Timing will show their advantages in helping to make more horsepower and broadening our powerband. In addition, I believe in the near future we will also start to see intake manifolds which will allow the VQ to continue to make power at higher RPMs.

 

The way that you have to fit them in there and the cross-member that is necessary for the swap, allows the motor to sit lower/farther in the engine compartment, as well as the firewall being modified(if I remember correctly). The VQ isn't the lightest engine and I believe that the weight difference is somewhere around 150 to 200lbs. You put a big snail on there and you're talking a different story though.

 

Pretty much.

 

The VQ35 is reported to be lighter than the 3.0 Vq30 it replaces. Weight of this VQ is only around 300-335lbs?

Weight of the RB is reported to be close to 600lbs?!

 

I was under the impression that the VQ35DE weighs in at about 350lbs and the RB, a little over 500lbs.

 

You can buy a kA24de for 500$......running.

 

You know, I've never seen concrete evidence of the weight of the RB. But from what I've read, the RB26 is alot heavier than the RB25 for some reason. I think the RB25 might be around 500-550. And the RB26 was much heavier at around 600-650?

 

You say VQ I say TT Viper.

 

just to let everyone know i'm getting the RB26, trans, and electronics for free from my brother's car. So that might change everyone's view on keeping and building the VQ.

 

This is probably a dumb question, will the AC still work if you drop in the RB26?

 

RWD versus AWD. I think that answers the question.

 

No ac man. You gotta lose a luxury to keep the heads turning. Who need AC when bugs provide cool refreshing sustenance at 150 with your head out the window.

 

Free?!@ That's not fair :flameon:

 

So you've got an RB26DETT engine, an RB25DET tranny, and a standalone EMS?
So if you were to take all of that up to JE Imports, you would still have to fork over at least $12,000 to $13,000 and everything on you gauge cluster would work except for the Tach. -I just got off the phone with them.

 

Not quite sure what you are getting at. We are comparing the weight of the engines only. Unless you are stating because of the AWD, it somehow translates to a very heavy RB26DETT engine?

 

Everyones input is really great guys thanks.

Now I only have a couple of weeks to decide to do the swap or my brother is going to sale the RB setup to someone else.

To let everyone know its a fully built RB26 swap vs building the VQ
