Can vk56 5.6l with 5sp auto fit in a 1st gen Q

[Cathode]

I was thinking about doing an engine swap to the 5.6l. Price wise a first gen Q is the best car chasis in the world, but I am wondering will it fit ? Also I was wondering will it fit in a J30 since in japan they came with v8s.

[Jesda]

The best option for the J30 is the twin turbo V6 from the 300ZX. For the G50 Q45, it'll take some creativity and money. You can certainly mate a 5-speed to the VH45...

[elwesso]

Sure, you CAN do it... You could proabbly swap in a ferrari V12 if you really wanted to.. The VK56 im not sure would really be that smart, im not sure how much faster itd make the Q, but id love to see it.

Sounds like a great idea to swap in a newish engine that already consumes oil, but I tend to like the VH45DE

[maxnix]

It's all about the money! Bill Harrah once swapped a Ferrari V12 into a Jeep Wagoneer and called it a Jerrari.

Truck engine is good for low end torque and faster off the line, but as a stroker VK45DE, runs out of lungs at the top end and is rpm limited by piston speed.

I think Wes is correct that the VH45DE would be the better engine to modify for more power. Also, the newer transmission is somewhat suspect for robustness at higher power levels.

if al you want is a 5 speed auto, just make the auto fit the VH45DE... IMO if you did that youd have a car as fast as the new M45.

[Cathode]

All I want is the auto, instant power boost, and the 360 lbs of tq. The thing is the 5.6l is almost a bored out mustang 4.6 engine. It is a shorter stroke than fords 5.4l (well almost every thing ecxept a diesel is shorter than that thing). I know it may sound weird but the biggest reason I want the 5.6l is to americanize the car.

Oddly the reason i am thinking about this is my 2006 maxima got totaled in december (was a month old). I respect nissan more now. It takes a hell of a lot of engineering to drive a 3800lb car off the freeway going 65, and flip down a 30ft cliff engine first with out any injury to the passenger (warning seat belts dont hold when car flips end over end). I cant really afford a an old m45, but need something to drive with rwd.

Wow..... Instead of "americanizing" a japanese car, why not just get an american car... ITS SO SIMPLE IT MIGHT JUST WORK...

that just doesnt make any sense to me... why would you go through the trouble of using a nice 1st gen Q to just turn it into a tire roasting monster, and putting in a VK56. I guess I can respect that youd stick with a nissan engine instead of using a chevy or ford engine.....

At any rate, itd be far cheaper for you to supercharge the car, i still have the hookup for the Q SC for around 3 grand.... Roots type and you wouldnt have to worry about the trans except having it built... I just dont think it makes any sense to swap OUT a VH45DE... most people put VH45DEs into something else, not take them out!

[Cathode]

Well one cool thing is the new auto is 50 lbs lighter. I could sell the vh45 and transmission to pay for some of the swap. Also torque saves money performance wise. If i did the swap the car would be truely one of a kind. There would be no car in any price bracket like it except for a 5.5l AMG. The odds are in general it would be the nicest q45 on the planet and STILL in my budget. If the swap is a no go then ill have to hunt for a 2003 m45.

[Jesda]

The biggest problem with American cars is the chassis and interior.The biggest problem with the Q, especially the 250lb heavier 94+, is the lame low-end power.Best of both worlds: Supercharged VH45.

Even better: 2003 M45. Its like the enhanced version of the Q (do a search for my review). When you buy it, share some pictures.

[elwesso]

OI guess it just seems stupid to do something like this, when the supercharger is waiting at your door for LESS than the price of the VK alone! VH>VK

[Q45tech]

Swapping a 5.6 OBD2 requires the ecu tcu and all the harnesses and dash electronic modules.

It will require extensive [expensive] electronic engineering to make everything work.

The mechanical part is easy: make some motor/transmission mounts, a custom drive shaft, and cut out firewall hood what ever to fit.

Who in the US is competent to redesign the wiring without more detailed schematics and software that are not available to the public.

[Cathode]

But thats all from a nissan titan truck. Americans are totally different on how they value a pickup truck. I predict youll find a large supply of rolled and totalled nissan heavy trucks with good electrics in greater quantities than you would find a q45. Ebay is parting out armadas already and the parts are reasonably priced. I am not trying to rengineer anything. It is just that if i spend 18k on a m45 i could spend the same on a 5.6l q45.

[elwesso]

I just dont understand why you wouldnt try something else first before trying to swap in another engine. Why spend 18k on an engine, when you could boost your already more robust VH45 to more HP and more torque? All on the stock motor.

There is a replacement for displacement: Boost

[Cathode]

But then I could by a 93 q and hamer the v8 into a j30. I am not trying to be funny or wasteful it is just that in general it is cheaper to go with a factory high displacment engine because the engine is running to factory specs. Also i live in california so a engine swap is better. Otherwise you have to get carb certified parts.

[Jesda]

But, on the plus side, a 2003 M45 will be covered for its value in the event of an accident. It'll be tough to convince the insurance company to pay you for what you invested in the engine and associated electronics on an old Q.

[Cathode]

True.

What I am getting in general is disappointing news. That basically the q is too advanced/expensive to modify. I have one question tho is a j30 a good canidate for an engine swap. I hate the look of the j30 but oddly it is the only 90s rwd I am satified with cosmeticaly. It has desined look instead of a cliche. Sorta a melted jaguar. Anyone notice that inifinitis line up look like various generations of ford um tauri. Can anyone say how a j30 engine swap will turn out?

excuse my spelling and grammer. I was in a rush to eat dinner.

[JohnPa]

Going back to an earlier topic in this thread, what would it take to swap a later 5-speed automatic into and early (90) Q? If that can be done realatively easily, I may be in the market. Seems my transmission may be the source of driveline vibration.

[HashiriyaS14]

The best option for the J30 is the twin turbo V6 from the 300ZX.

I actually passed on a VG30DETT-swapped J30 for like $4k once. I'm an idiot.

Still available:http://j30.omitframepointer.cc/

[elwesso]

main thing about the J30tt is the engine mounts up as far as I know the main hurdle is a lot of custom plumbing

[RobertsnewQ]

J30 also fits the VH45 too!

Available in Japan with the VH41

Since the VH45 weighs less than the VG30DETT, that would be a nice swap too.

[Cathode]

talk about the best thread hijack ever so the j30 seems to be a better canidate. Nice. Do you need a new "k-frame" from a JDM leopard j F for the v8 and can you use an USA m30 frame instead? I techinically like the j30 more than the q because it is ugly.

[RobertsnewQ]

Good Q on the k-frame. I suspect no, because it is similar to the 300zx. Ask slim (450zxtt) what he had to do to his k-frame.

[Cathode]

The thing is if i can get a jdm v8 k member this could be a bolt on swap. also it would be like driving a 4 door mustang cobra except lighter *dig* you know a j30 v8 would be the on of the best sleepers from any manufacturer in the last 20 years.

[HashiriyaS14]

You think the J30 is a better looking car than the G50 Q?

I've certainly never heard anyone say that before, lol.

[midnightsliding]

if u want something go for it if it kool to u go nutz. not many ppl liked my idea at first but not their crossing over. here is Chris new car for the up coming season. its a 350z with VK56 in it.i say go for it if u can fab things up ur self then its all eay and not costly.

[Rex]

I took it as he was saying he liked the J over the Q, because the J is ugly.

[Cathode]

No I said I like the j30 because it is uglier than the q. Its the same reason I like the aztek or the gremlin. Its a car that no matter what you do you cant mess it up. thx for pix btw. why in gods green hell did they put it in a vert?

[irax]

that car was built for irwindale speedway D1GP or FD. That z is factory built by nissan, so that cars shell is lighter then any dealership z that was stripped.
