Hey guys,

I was wondering if it was possible to swap either of these engines into an 03-06 Z/G cars? If so what would be needed to swap them in?

 

Sounds like a waste of money go FI.

 

+1
For HP per Dollar, go FI

 

well the reason i would do it is so i could eventually F/I the engines but i want the VQ37VHR because of the added displacement and the VVEL or the VQ35HR for the dual throttle bodies.

 

actually forget the vq35hr i just want to be able to swap a vq37vhr and then F/I it.

 

anything is possible

I'd bet you'll spend at least 15k-20k to do the swap....pre turbo kit

 

For the price you would pay for the swap you could send the motor to GTM and get a 4.2L stroker put in it.

There you have even more displacement.

 

^what about the VVEL? thats what i want the most and i dont want to wait till 2009 for the 350z to get the VQ37VHR Motor. Why would the swap cost 15-20k? The G37 and 350z use the same tranny dont they? i would just sell my longblock and buy a g37 longblock and ecu.

 

Its your money. We're just telling you how to spend it more wisely.

 

+1 on the 4.2 stroker kit. Just go that way with a good TT, that is all you will need.

 

4.2l stroker + Twin Turbo setup > VQ37VHR

More power, better sound, cheaper, yummier

Forgot to mention... MORE FUN???

Okay but as i stated i want the VVEL as it is a very promising system and the fact that its going to be used on the 2009 350z or 370z shows that it has promise so the only reason i would swap in the vq37hr is to get the VVEL and dual throttle bodies also Sam at GTM is making a 4.5L Stroker kit for the HR/VHR motors!

Sam from GTM says the swap is very possible as the only differences are the deck height which requires a new hood. The VHR longblock is about 8200.00 which is expensive but, if you sell your current longblock it will only be about half of that which aint that bad. So i guess Sam answered the question for me.

 

you know whats to wonder.

why do they change so fast.


there is yet a complete ecu for an DE. wtf is up with that

i dunno. why get an hr when u can just wait another 3-4ys for another

oh// i would like to wonder how would u swap too/ dont be as* and tell him what todo.
would a hr fit a de tranny?
you would need a new hood too.
engine mounts are also something to think about.

i dunno it would be cool tho

 

I don't think it's that everyone is being an *** to him, they're just presenting all the other options. If you weigh the cost for hp gained, swapping a G37 engine is just not cost effective for an extra 20-30whp. Of course the cost of the G37 motor will slowly drop in price as well, so maybe in a few years, it'll be a more cost effective option. For right now, I still the stroker kit mentioned earlier is the best bang for the buck. More displacement than the G37 and much much cheaper. Either way, both the stroker and G37 motor will require either a new hood or hood modification.

 

because you are forgetting about all the work required to integrate the harness from the later car into the early car- Im talking ALL the wiring which is completely different from past to present, from the ecu, to the dashboard connections. For example, do you know how many different gauge clusters there are between the 06 and 07 cars? Do you know how many different wiring harnesses? You could go numb just trying to sort through that stuff alone.

Your currently long block also isnt worth all that much - a couple grand at best, hardly enough to make a dent in the overall cost.

I'm not meaning to be rude, I am being realistic. I own a shop, see these cars in their entirety day in and day out, and know what is involved in modding them extensively without doing a big job such as a HR swap into a pre HR car. If you think you can accomplish this on the cheap, more power to you. I'm telling you what I think it's going to really cost by the time it's all said and done.

They change fast because that is the nature of the car industry. Latent products don't sell, and there is a desire for a manufacturer to be ahead of the curve, or at least riding the wave of current available technology at every turn. With so much platform sharing going on, it is obvious why manufacturers keep chassis consistent through a product lifecycle and adopt new powertrains to them as the product runs it's course.

BTW - no ecu's for a DE? Huh? There are several in fact, from plug and play piggybacks to full out standalones.

No one is being an *** - we are being pragmatic. You would be far better served to sell the 03-05 car and buy a new, or slightly preowned 06-07 (you get to take advantage of depreciation too) in order to do a "swap" like this, vs trying to reinvent the wheel. It's like someone who owns an Eclipse GS, asking if they can swap in a GSX motor and drivetrain. Sure it's possible - but why not just sell the base model and buy the real deal from the get go, and start modding from there? Slightly higher upfront costs for a lot less headache down the road.

Agree with Adam

your gonna be spending a ton of $$$ just because you want the VVEL???
Hey, anything is possible with $$$ but what a stupid way to spend it.

If you want it that bad, sell your Z and get the new G37. You just got the "VVEL" you wanted, Problem solved, end of story....

 

anyone got a price out of GTM for the 4.2L longblock?
