Will a gtr motor swap into the 370?
 

Will the motor fit with slight modification or is it a major engine swap?

Its never been done to my knowledge. It would cost a arm and leg no matter how you look at it. VQ37 seems to bee a good engine too. Money wise it would not make sense to put gtr motor in the Z, it would be nice though!

if it was an awd gtr swapped 370z thatd be cool. :p. id love to see what all that would do weighing a couple hundred pounds less.

When you're done, you'll wish you just bought a GTR instead.

Amen

do u know that for sure?. i mean your talking about the same beast, still appealing, and smaller/lighter after all the transplanting. i dont know if that would really be the case here.

it would be cheaper to buy a 2012 gtr, do the standard upgrades, and then it would mop the floor with your 4wheel drive z once again. Just a z and the transmission from the gtr, no engine no labor no custom machined parts, no tuning, no wiring, is already 50,000 if you can even find the transmission

How is it the same beast? It becomes a mutant 370. Sure, its the same motor and running gear, but how can you say its the same beast? I highly doubt the Z would be a great car with the jacked up balance and power. The GTR is incredible because it was designed that way. In my opinion, that greatness is not transferable

Cheaper to just build the motor we currently have.

Makes no sense to do.

I keep hearing how expensive it is to do an engine swap, but when I was stationed I. japan the big thing I saw at the Tokyo auto salon was skyline engine transplanted into Silvias.

It will work if you have the funds, but then again I would just buy a GTR :)




DAN

there is a wrecked GTR on E-bay for 35k. That's what perked my interest...

Just the motor swap, not tranny, would it bolt up?

Have you ever done an engine swap?

I've never changed my own oil. But that's not the point. Engine swaps have been done for ever. Why are people saying it's too expensive for the Z if no one has done yet ( I'm not just talking about the GTR engine either). Why are they singling out the Z like it's got a completely different set up than any other car out there?

Partially because it does, partially because the first swap is always the most expensive. It makes literally no sense to spend 20 grand or so swapping something different into a Z, when you could just get a different car instead.

The 370 is not a special car in a pretty much any way. People buy them because they're new and have a warranty. If I want to swap an engine into something, I'd buy something lighter.

Because he wants to transplant an engine from a $35k wrecked GTR into his $35k 370Z. That's $70k in the hole without even having done the work or troubleshooted the multitude of problems that are ahead of him.

When he's done, he'll look back and wish he just bought a GTR. Unless it's done right. Then he'll look back and wonder why he paid more than a GTR costs.

Swapping a GTR motor into the Z is stupid. could it be done, yes, anything's possible with deep enough pockets. You won't be able to reuse the tranny though, since the GTR's is rear mounted and I don't want to think aobut the reengineeirng that would be needed to make that happen.

Cheap and reliable motor swap for more power: 370z w/ an LSxx motor and tranny dropped in.

/thread.:tiphat:

I got that the GTR engine is hand built and costly. But people say the same thing about cheaper more powerful crate engines.

The issue is the "first swap cost", like I already said. Making things bolt up is extremely time consuming. If you don't work on your own car, you have literally no idea what goes into a swap, and it's just too much work to explain it...

What costs more when it's all said and done

1. Engine swap using a GM LS crate engine NA at 600 HP or
2. A TT setup tuned to 600 hp with all the internals required for that HP

for the first swap, the swap...at least, assuming you are paying someone.

Most people would be paying someone else to do the work.

probably not most people that do an engine swap...at least not in the circles I run.

g37x easier swap , then tt your motor. Just sucks g37x is only in auto :(

why swap that? AWD?

I think he's saying put the g37x motor into the z. But it's the same motor it just also drives the front wheels

Howmuch different are the motors? Are the motor mount locations the same? Are the bell housing holes going to line up?

A 35 k gtr on eBay can be parted out. All I would be interested in is the motor, if it will n deed just bolt right up.

Can it even mate up with the Z transmission or will you need that too?

You'd probably have to fab something up.

From what I hear, the GTR is boring to drive compared to a Z so I say all the fun power + all the fun driving = win

first off, let me ask you why? the GTR's engine is nothing special. its just a 3.8L V6 with TT's making ~500hp. you can TT your Z for a few grand and be putting nearly the same numbers down.

the GTR is a spectactular machine, not because of its engine. its the combination of its engine, transmission, suspension, chassis...etc. the entire package is what makes the car so beastly. not its engine. only a fool would try to swap a GTR engine into a Z.

G37x trans and front diff was what i was trying to say on my phone. No not the engine haha its the same. Its just an idea :)

exactly!

I think there is actually clearance to swap it in there, surprisingly. I'm not really sure why you'd want to, as the system isn't really optimal, and it is also fairly fragile.

The GTR engine is far superior to our engine though. Besides the solid-ass bottom end, the engine has actually been designed with boost in mind, rather than in pulling a few more NA horses from an old design.

I agree withe the reliability aspect. "Built in" is always better than "bolt on". But you can't argue that an engine swap is any less costly or risky than TT'ing or SC'ing a VQ.

Either one is a scary proposition though.

The engine is way more reliable than our motor boosted. If the motor alone could be purchased with all the hardware and it would bolt right up I don't see how this would be foolish, but what ever call me a fool.

Hit the nail on the head right there.:iagree:

Can the swap be done? Sure. You could swap in an engine from an F16, given enough time and money.

The real question here is why do you want to do the swap? What is it about your Z that you find lacking and are trying to solve via the engine swap? If it's just HP you are after, there are other more cost effective and easier ways to address that; many of them mentioned already. If the answer is "Because I think it would be cool to be the first person to do it", then OK. I see your angle.

As you stated, you don't do much in the way of wrenching on your own car. That's OK, it just means you will have to pay someone else to do the work for you. You have to take into consideration that you will be diving into uncharted waters which translates into a lot of trial and error on the part of the shop doing the work. That translates into more money out of your pocket as they experiment and try to get it right.

I cant even begin to estimate what it would cost, but let me give you some perspective, from the position of someone who HAS done a number of engine swaps. I found the 135 HP in my 68 Datsun roadster to be lacking and swapped in an SR20DET from the JM 240SX/Silvia. I did all the work myself, except for the exhaust. I had tons of technical support for the guy who pioneered the swap. I had access to all the tools and equipment I needed. The engine practically bolts right in with very little in the way of frame or body modifications. Even with all that, it still took me 6 months and more that $10,000. Just to do a really basic swap, with no technical hurdles, that had been done many times before me, and with me doing all the work.

I don't want to rain on your parade because I think it would be really cool to see someone do the swap you are talking about. Just understand that whomever that someone is will be into this well over $100k by the time it's done. if you have the pockets for that, do it! We all want to see it!

I wouldn't admit to that...
