VK56VD Direct injection
 

Hey guys I just found out that Nissan makes a version of the VK56 that has direct injection and thus a more slim intake manifold.
It will most definitely fit under the 350z hood.

So for all you guys doing Ls swaps, maybe knowing this will help you stick with a Nissan engine. It's making me rethink things.

And Nismo ran the VK45 in the 350z and VK56 in the GT1 GTR so you know it cant be a bad idea to use the engine. It's DOHC too.

A man can dream

Hows the aftermarket support for the VK56?

They sound good too.

This is the VK swap everyone should be doing because on the DE you have to either cut the hood (No way I'm cutting my MCR hood) or run ITB's. (Expensive and challenging)

So with this swap the VK56VD you get
-420hp/417tq over the 315hp/380tq
-Probably wont have to cut the hood. (Good chance)
-Use your 350z transmission.
-Dont have to mess with ITB's for a clean hood.
-Drive by wire throttle bodies
-Dual intakes
- Higher revs
-?

Gotta have a custom exhaust, drive shaft, and maybe engine mounts. A adapter plate is needed for the mating of the transmission.

I've actually just recently started some light researching about a possible VK swap.

^^^^That is my main concern right now. I've been trying to find how well the aftermarket is before I consider anything further. So far it seems pretty slim, and only found one site that only offers piston packages. But again, I haven't searched very much yet.


*Update* Of course there is cam support from JWT, but kind of assumed that anyway, haha.

Engine is frigging Expensive!

I'm sure the bottom end can be built and cams with a port n polish would be a nice compliment.

I can't find a price anywhere...

I wonder if those cams are meant for the titan version. Guess Ill research to see what nissan did to the longblock to gain so much power with the same displacement.

If you really want more info about doing the swap in general, Silver350zed can surely enlighten you...

Start at post #176 and read from there. Interesting swap to say the least.

Most of the aftermarket will be custom... Get a hold of MA Motorsport.

i've been thinking of this for a long time.. if anything ever happens to my titan that's the route i'll be going. but with a different chassis. going to keep my current one with the DE.

The V8 with bolt ons would be enough power for me since I already think my HR has enough. I would love the VK power without the problems FI bring. Nothing but a motor to worry about


Chris Foresburg makes like 550 know a VK

Damn that M56 sounds mean!

Ebay was 6K+

So, are you all seeing why people go with a LS over a VK? It costs way less, is an easier swap, and you actually have an aftermarket.

The VK swaps have been done, I have never been impressed by one yet

I know why, and here I'm just showing that Nismo uses the v8's in the racecars so why not in my car. And the VK56VD will make a cleaner swap because it has a lower intake manifold, and makes an extra 100hp tho it's more expensive yes.
If the engine on a stock M56 makes 420hp then with LTH's, exhaust, intake, tune, should make 420whp. Throw JWT cams in and get another 30whp maybe.

I like Chevy V8's, but if I could keep it Nissan that'd be cool.
In my eyes the swap is fairly inexpensive.

I've dreased aboutique this swap for years before I got a 350. Just seems out if hand for a normal guy like me who does his own work

You realize you are talking about spending $10k+ (with a big emphasis on the +) on the same power you could make with a supercharger on the V6? The whole point of the V8 is to make gobs of power, lots of torque and boost the crap out of it. I don't see the justification of all that money to "keep it Nissan"

Thats ok. I've considered lots of engine options for my car when the time comes.
I've found a V8 would be the best bang for my buck and reliability. Keeping it Nissan would be ideal.
Adding a super charger wont get you 400+ ftlbs torque. And V8's are cooler than a V6. It might actually get the car some respect. lol No one thinks 350z's are fast.

Meanz car seemed to do it just fine

No. The reason is I can make that much power and stay NA while keeping it Nissan with an engine I like.


Like I was saying. I understand what OP is getting at. I'd never attempt the swap thiugh. I don't need more power anytime soon

Ya ok so someone has. I'd have to spend all kinds of money on my Rev up to make 400+ so.....
I seen you talking about a LS swap in another thread from 2011, have you done it yet?

If you want me to admit the LS is easier and better than ok it's true. But a built VK56 that fits under the hood has a lot of appeal to Nissan enthusiasts.
Understand?
This thread is not to debate a VK/LS swap it's to point out that the VK56VD would make a better choice based on the intake manifold and it makes 100 more hp stock.
Thank you

Makes close to 800 N/A, 1000 on spray.

I want to see a build thread for that engine!

im curious if the total engine size is the same as a de or if its smaller/bigger. ill take this over a ls anyday

Bigger.

Smaller.

I know this is an old post but I was researching more about direct injection engines and there are pros and cons. The pros is that they are more efficient and make more power the cons are the carbon build up on the valves that have to be walnut blasted every XXXXX miles or so. To me its not worth the extra money. What happens is on a port injected car the injectors wash the back of the intake valves and they stay clean but on a direct injected engine the back of the valves never get washed with the fuel and they get gunked up with black carbon deposits and have to be cleaned. The ONLY company so far that I have seen address this is TOYOTA with their newer direct injected engine. It has DUAL injectors; one direct and one port for each cylinder so that the port are the secondaries that are used to wash the back of the valves so the carbon never builds up on them and never need that service done. I hope all the other automotive companies follow suit......until then. LS SWAP for me!

From what I recall of pics of swapped VK56 vs LSx, the LS looked a bit smaller (IIRC the weight of an LS was similar to the VQ? as least the aluminum block? The VK56 probably is heavier) which would be good for piping I would imagine. Also the whole thing about going down the street to get a part for an LSx vs. ordering a part from Nissan and waiting. I know when my VQ was getting built and we had to get things like shims/chains/sprockets/buckets it took forever to get from Nissan as they were on back order.

I get the reasoning behind keeping it Nissan, but like others have said, the allure for me for a V8 engine in the Z is for the v8 boosted power potential to get to big power easier due to the literage. I'm still enjoying my TT'd VQ, but am slowly saving up for a Sikky. If your budget is like 10K, I'd say just got TT/Supercharger on stock block and enjoy 400-600 HP and forego the swap as it's probably going to run way more than 10K anyway.

So I bought this really damaged M56 to do the swap finally!!!!!!!!! It's been done already now too by a G35 owner, but I'm sure I'll have the first VKVD Z in Canada!!

I didnt do too well on the donor car however it's badly damaged. The engine was damaged too..... But it can be fixed as far as I know. I am going to do a used oil analysis and a compression test before I do anything, but this is a winter project for me so pregress will be slow. I'm just parting the car out now to get some money back out of it, then I get to testing it. Hopefully by next summer it will be in my Z!

Hate to say it, but that wrecked M56 looks like the engine may be too damaged to be of much use. Unless it actually starts and runs, a UOA will likely only show what its condition was BEFORE the accident. Compression test may also be inconclusive until you actually cut it out of the car and do a full inspection of the block and ancillary parts. BTW- the VK race motors used in international racing are actually full race motors engineered by NISMO in Japan. Only the base block is similar to what we get in street cars..
