GTR R35 into my FX35

Guys,

I have a crazy idea to install a GTR R35 into my infiniti fx35, instead of paying 10K $ on GTM turbo on my 3.5 engine which is over 200K km now. There is big chance that it ll fail after installing the turbo, so a new engine ll be required.

So my inquiry, what I should take care of if I planned to the GTR engine, shall i change the transmission/gearbox 2 which is a big issue ll be cuz if so i need change the differential 2. GTR transmission is in the rear .

Would like to hear from u guys n use ur valuable inputs [emoji5]️

I think this will cost a lot of $ bro. Why not just sell your fx and get a GTR?
 
This has already been discussed on this forum in the past. It was decided that the project will be cumbersome besides very expensive as it will involve a lot of customization. For starters, the GT-R has a rear mounted six speed dual clutch transmissions that is used in conjunction with the ATTESA E-TS system. This is totally a different set up than the traditional placement of the transmission in most modern cars including the FX. That alone involves a lot of body and possibly frame work custom work to get the GT-Rs transmission fit into the our FX.

Like what gto said, this is an insane project but I don't mind to follow the process of one actually doing it.

You would basically need an entire donor GTR to make the project remotely possible, then you would have countless hours of fabrication and work to move everything over.

It can be done, anything can be done. If a GTR drivetrain can be swapped into a Juke, then no doubt it can be swapped into an FX.

I just don't see the merit, might as well just swap the 5.0L V8 for which you can just grab off the shelf parts for the retrofit.
 
Why not just swap in a built HR and turbo it? That plus a built transmission would probably be in the $20K neighborhood, maybe $25K and you'd be at very high power levels. A used GTR motor alone will cost you $20K and another $5K for just a used transmission. Then the rest of the driveline and custom fab would eat up a ton of money. You'd be more than halfway to the cost of a GTR to do this.
 
The R35 motor could probably fit in the engine bay with customization of the engine mounts. The hard part would be the transmission, differentials, and drive lines, since they are no where near compatible with the FX. Oh, don't forget tuning and wiring as well. Anything is possible I guess, but it would take significant time and money.

I'm thinking of getting a GTM twin turbos as well in a few years. My recommendation for you would be getting the turbos now, and replace the motor and transmission when they fail or get GTM's built motors. Or if you have extra cash now, you can pick-up a used set for about 5k with ~45k miles. I saw this in a classify ad a while back. I can't remember where.
Of course, after you put in a new motor, you would want to re-tune.

Sad to say, but turbocharging an engine is not cheap. An alternative solution is supercharging, which could save a few thousands.

I think anything is better than something from the crooks at GTM.

Where is the enjoyment [emoji16]
Need to do something crazy
Buying a GTR then need to modfiy it again to compete with GTRs [emoji1][emoji1][emoji1]

Thank you guys for the valuable inputs,, much appreciated..

You're welcome. Trust me when I say that "probably bolt right in" is an oversimplification. It wouldn't be cheap, nor easy, but it would certainly be cheaper and easier than doing a GTR swap.
 
Best route would be rebuild your VQ35HR, depends on your budget, you can just do simple rebuild, mild stroker to 3.8 or making it a 4.2. Custom TT kit. Upgrade your transmission and drivetrain and you should have very fun car.

Out of the box route would be an engine swap such as LS swap, etc.
 
I read alot on this supject on my free time when I had some, I came across an intersting info but don't know how reliable is the info..
from what I read, that when they where planing to manfacture the GTR 2009, they were n't actually sure that having the gear box in the rear would work, so they were trying to work in paralel to seetup the engine to work with one of Nissan/Infiniti 's gear box, that is why the GTR has a flywheel. His justfication ( the one am qouting from him ) is if it is planned from the begining as a rear mounted gear box then it ll not need a fly wheel...
I don't know if he is correct or not and I did not reach to that Technical level yet.. if someone appreciated could tell us more on that.. :)

looking to hear from you guys
 
Well, the GTR is the only car with an AWD transaxle transmission - transmission in rear and AWD. But it still needs a flywheel to transmit power. Normally, engine spins flywheel which then mates with the clutch and turns the gears. On the GTR, engine turns the driveshaft which then mates with the flywheel which then mates with the transmission in rear. The difference is that it's not directly connected to the clutch like on a standard design.

Technically the flywheel isn't necessary on a design like the GTR, but I'd think not having one would make the car really hard to drive. The flywheel helps to smooth out engine vibrations, if you don't have it, your car won't idle. It also acts as an energy storage device - as it spins, it's storing energy which can then be transferred to the wheels. That's why lightweight flywheels are so hard to drive smoothly, as soon as you back off the throttle, there is less weight and less momentum so your revs start dropping.

So while they could design that transmission without the flywheel, they'd have to compensate for it by redesigning the driveshaft to perhaps be heavier in order to perform the same functions. It seems easier to leave the flywheel in.
