Nissan 350Z with FX45 V8 Engine

Looking at the photos of both cars engine bays, I think it might be possible to fit the VQ45 into the 350Z. I'm assuming that this engine is 140lbs heavier, just by subrtacting the FX35 weight from the FX45.

The 140lbs of added weight shouldn't be such a big deal. I'm sure it can be made up for (not totally, of course) with a CF hood, CF fenders...

If the added weight doesnt affect handling too much then I might consider doing it. If its possible.

you will have to measure the dimentions of the 350z engin bay and see it the vq45 will fit its fat self into there, i mean its pretty cramped their isnt much space for even the greddy turbo kit soo good luck

Well i think it will fit width wise. But the tranny tunnel will most likley have to be opened up a bit, and some serious fabrication of mounts. But please dont go and put a V8 in the 350Z and turn it into a 450Z. The car is almost perfect the way it is. Dont mess with it, unless you have turbocharging in mind:D

haha 450Z good one. God, I don't even think you can even fit 1 turbo let alone 2. A man can dream...a man can dream.

Hey how about we bore and stroke it to 5.0 litres and place the turbos somewhere below, close to the radiator. That actually might work. We could even TT it. My god imagine the possibilities! 5.0 TT 1800HP 2000LB LOL. The only person with a Nissan 500Z :biggrin:

my 500Z TT does 8second 1/4miles. Its ok, only 1800hp:)LOL

The only problem with putting the turbos near the rad would be the excess heat to the cooling system. It would make it very hard to run at high speeds. I would suges tou wount them more near the top of the engine bay. And make holes in the hood for the air to get the the front wheel of the turbo. I have seen it done on some supra drag cars. The make a hole in the hood right where the turbo intake pipe would be , essentialy eliminating the pipe and raming the air in. That would work better for cooling as well.

O no, now i need ALOT of money:D

Turbos sticking out of the hood? Nah. I didn't mean behind the radiator, more like to the side. I think it's fesable with a wider air duct (Gotta get a body kit that has a wider air inlet, thus allowing the turbos to breathe easier) Then there wouldn't be "pull me over" written all over it. The VQ is already one of the best engines in the world, how about a bigger version of it? :D Toyota was scared of the VQ's presence in JGTC, so they put in a V8 in the Supra. Considering how heavy that old V8 must be, I'm no longer afraid of the weight gains. With the VQ45 in place, it would still be 436lbs lighter than an SVT Cobra. :) Not to mention strong NA numbers. Right now the VQ45 uses a crappy intake system, limiting it's performance but I'm sure we can fix that.

The only imported sports car with a V8 and 330+ TQ NA... :rofl:

It seems that I have made a miscalculation. The VQ45 is only 89lbs heavier than the VQ35! That's very good news!! The 140lbs I got earlier was from subtracting the AWD version from the RWD version. :)

Would the 6speed tranny fit the larger motor though?

Why don't you try it? A new FX45 V8 engine shouldn't cost any more than maybe $12,000 from Nissan (I know of someone who paid $9,000 for a new 350Z V6 engine from Nissan in Japan). And you can take the V6 out and sell it to someone who blew their engine with a procharger. LOL

If it fits, you might just have yourself a cottage industry converting cars into 450Z's.

Hmm Ok you know what, I will try it, as soon as I get more money. Right now I am living alone, and I have to pay rent :( So it might be a while before we start the purchases. Wish me luck.

The engine should fit, with some work. Since the FX and the 350Z are both based on the FM platform, the engine bays are probably similar in size. There may be some issue with the suspension, since the FX uses a different front suspension.

Impul in Japan supposedly makes a stroker kit for the V8 that takes it up to either 5 or 5.5 liters. I can't remember which.

If there isn't room for turbos, how about a supercharger? There is one available for the Q45(same engine) from Keuylian Motorcars, good for 450hp, a gain of roughly 100hp, at only 7.5psi. That power comes from the blower and the air/water intercooler, and everything else is stock. On Freshalloy forums, it's been suggested that the stock exhaust is very restrictive. An aftermarket unit could free up a lot of additional power. Unfortunately, the blower costs about $10k.

Oh, and by the way...The V8 is a whole different family(though still related to the VQ), called the VK, not the VQ. ;) The 'Endurance' engine found in the Nissan Titan pickup and Armada SUV is basically a VK as well, albeit stripped of the CVTC and expanded to 5.6L.

Although it isn't a V8, there is also the option of the VQ40DE, once it debuts in the '05 Frontier and Pathfinder. Both it and the Endurance offer lots of torque, and would be an interesting powerplant for the 350Z.

Wow a stroker kit for the V8 already. I've got to see this. Sorry gotta go with the legendary "twin turbos". :)

Keep in mind the VK45DE V8 isn't that new. It made it's US debut in late 2001 with the '02 Q45. It may have been in Japan for even longer.

The VK does have some potential, but you might need to work for it. To start with, it is an undersquare design(stroke > bore), so it doesn't have a revvy character.
Reduce the stroke a bit, add hotter cams, more compression, bring displacement down to around 4L, and you'd probably have a sporty 400hp+ V8 worthy of placement in the GT-R. At least that's what I was hoping Nissan would have done, anyway. :mad:

Infiniti's Indy Racing League motor is made from a VK block. It is reduced to 3.5L, turbocharged, and runs on methanol, producing 650hp.

I don't know why it shouldn't fit into a 350z engine bay since the new GT-R is based off the 350z and has the 300kw V8 in it....

Do you guys know of any publicly available VK parts? I really do not have time to develop my own internal parts. Fabricating an Intake, headers, and exhaust maybe, but internals could prove a bit difficult.

Could you get away with looking for pistons that are the same size as stock? The only aftermarket pistons I know of for the VK are probably part of that Impul stroker kit.

With con rods, you're probably on your own. I think a company called BMR makes an exhaust for the Q45, but I'm not sure what generation.

Hmm. I don't think I want a stroker kit any longer. It's really expensive. For the price of a stroker kit I could most definately make a TT kit and get much more power.

why change the engine from the z anyway? in my opinion its a waste of money. the z with a vortec supercharger can make 450whp. plus the z is already too heavy so adding weight is a big no no in my eyes. however, if you did do that it would be soooo original! that would be cool!

The VK is undersquare but that means it has less stroke than bore.

Also, as far as I know the VK56DE is not a modified VK45DE. It's a completely new long block designed for truck use.

the engine is i believe a vq45de, its in the m45, is there a transverse transmission that would bolt up to that puppy? If you look what its made out of its crazy, it has titanium valves and moly coated pistons, its almsot good for 10psi of boost out of the box, the compression is 10:1 though. i think for a n/a engine its is high on the chart as in hp.

There is no such thing at a VQ45DE.


Again, the V8 designations start with either VH or VK.

VH45DE '90-'96 Q45
VH41DE '97-'01 Q45
VK45DE '02+ Q45, M45, FX45
VK56DE Titan, Armada, QX56

actualy if you look on google there is a vq45de, i think its an american name...

There is no such thing as a VQ45DE. There are only people like you who mistakenly think there is one and they litter the world with bad information.
The VQ prefix ONLY represents the VQ V6 line which debuted in the 1995 Nissan Maxima.

The following versions are:

VQ20DE (Never offered in the US)
VQ23DE (Never offered in the US)
VQ25DE (Never offered in the US)
VQ30DE ('95-'99 Nissan Maxima)
VQ30DE-K ('00-'01 Nissan Maxima)
VQ35DE ('01-'04 Pathfinder, '02+ Maxima, '02+ Altima, Murano, FX35, 350Z, G35, M35)
VQ40DE ('05+ Pathfinder, '05+Xterra, '05+ Frontier)

The VQ40DE is the largest of all the VQ v6 engines. It is built in the Decherd Engine plant in Decherd Tennessee along with the VK56DE v8.

If there was a such thing as a VQ45 it would certainly be on that list.

i figured it out... the old 4.5 is a vk, the infinity m45 03 has a vq

You can't even correctly spell Infiniti. Why are you still beating this dead horse. YOU ARE WRONG. I have given you the correct information several times over.


THE OLD V8 IS THE VH45DE
THE NEW V8 IS THE VK45DE

THERE IS NO SUCH THING AS A VQ45DE!!!!!!!!!!!!!

Honestly it doesnt even mater ne more.... its just a car.

Go here and see if you can find anything called a VQ45

http://www.nissan-global.com/COMMON/_SEARCH/PrSearchServlet

There's definitely no such thing as a VQ V8. Listen to SR20DEN. People here tell me I know a lot, but from seeing him in action on Maxima.org, SR20DEN knows way more than I do.

There is always someone who knows more then you. Thats why such place as this exsit =D

O and don't swap the engine -.-. The only swap that I would ever think of would be the RB26 engine. its already done but if I can have it done in my car =D I would be really happy=D

Without beating the horse to death, I'd like to add some information here.
SR20DEN is correct. There is no such thing as a VQ V8 Nissan or Infiniti engine. The VH and VK engines are on the same block but the VK has different heads than the VH. Difference being valve material and port design. By putting VK heads on a VH engine you'll gain 62 HP. Not a bad upgrade.
The VH45DE engine is 501 lbs, which is 100 lb. lighter than a VG30DETT engine in a 300ZXTT. The width of the VH45DE engine is the same as both the 350 and 300Z engine, only longer.
The VH45DE engine with VK45DE heads will have 340 HP and with a good free flowing exhaust and decent cold air intake will produce 400+HP. Now that my friends is with a N/A engine. Now by adding a rear TT setup with 8# boost you'll be looking at 600 HP, with tons of torque. Now thats what you'd call one bad ass car. Is it possible to make such a swap? YES. I know of 3 350Z's right now running around now with this swap. Plus some 300ZX's and a few 240 and 260Z's.
Infiniti didn't choose this engine as it's platform for building the A35 Indy engine for no reason.
As for after market parts for this engine, lots of them.

:1:

I was wondering how long it would take for Albert to chime in with the right answers.

Wheres albert been?

I like this rear spolier, has anyone seen other pictures of this body kit in different views? I was planning to order this but am scared it might not fit perfectly as I am a perfectionist.

I'm going to have to get hold of those people and see if the've done any wind tunnel testing with that kit. I'd like to try it on our car after the salt racing, in the Silver State Challange.

Personally, I think it would be a neat project, nothing more than that.

There are plenty of other options for more power. Like I said, it would be neat. Other than being able to say "I did this and no one else has done it yet."

The problem isn't making more power. I can make all the power I need. The problem is being able to have a car that handles at hi-speeds and corners like it's suppost to.
There's alot of difference in driving 150MPH and driving 200+. Same in cornering. That is what ground effect kits are for, not for saying it would be neat or looks but something that works.

To clarify, there are other options of making more power means you can use the VQ35DE and go N/A or F/I before swapping the motor. So a 350Z with a V8 that weighs more than the VQ35DE is going to handle like it would with the VQ35DE?

They are for downforce and providing the least resistance to wind in certain places. However, hardly any body kit companies take the time to perform air tunnel testing for this. And if they did, body kits would be around $4,000.

Once again you've shown your inability to stick with the subject matter. But being you talked about it, Yes, a V8 (VH45DE) can and has been put into the 350Z and the end results were a lighter car.

Now back to the subject. Downforces and not allowing air to get under the car is very important. The 350Z has a very low drag cofficent, but if enough air is allowed to get under the car it will fly.
And your wrong again. Top-end ground effects body kid company do wind tunnel test there kits.
We've tried 2 different ones in the wind tunnel and there not acceptable for the speeds we intend on running.
We've found by lowering the front 1" we can go 75MPH faster before the car lifts off the ground.
What have you found out? I'd like to hear.

Look at the title of the thread...."Nissan 350Z with FX45 V8 Engine". It has? Pictures? Link?

You're*. And, apparently, you can't comprehend, I said "However, hardly any body kit companies take the time to perform air tunnel testing for this. And if they did, body kits would be around $4,000."

There not ground effects kits, there dressup kits. Alot of difference. Ground effect kits are made for one purpose, and some (the good ones) cost more than $4,000.

Dressup kits are nothing but something to appeal to the car owner.

Good ground effect kits are designed and wind tunnel tested and most MFG's well supply specs. with the kits.

Why is it you always avoid the questions and come back with remarks that are unfounded. I try to answer questions and you avoid them.

Please do everyone a favor and go play with your marbles some place safe.

wow...this is going on in this one also.

Sorry but yes it is. It seems a few people like to cause problems on the threads.
Now back to the thread.
The RB26 is a great engine, and would be a super power plant for older Z's, but I think Nissan offers better and more modern engines for the 350Z. The engine in the 350Z is killer and not too bad considering it has about 300HP and N/A. For those wanting and can handle more there's the turbo or supercharger option, and for those wanting the ultimate car the VH45DE is the engine. Like I said earler this was the engine Nissan chosen to run in the Indy cars. Why? simple, a 2,600cc engine just won't keep up with a 4,500cc engine, or in the Indy's case a 3,500cc DOHC V8.

Like I said in the PM, I gave my opinion, you tried to prove it wrong instead of saying you disagree, there is a big difference.

Why don't you both cool your jets?

You each get a warning. Either learn to live with each other on the board, or go elsewhere. And I can help make sure you go elsewhere.

Cool the attitudes, tempers, egos. Both of you have valid points. Agree to disagree.

Lets move on, shall we?
