vk56de or rb26dett into 350z
 

i know i'll get flame for this but who cares right! i like the vq35de nice motor but ,i always like to be different everyone has a turbo or supercharge vq35de but not everyone has a rb26dett or a vk56de in the 350z ?i know there like 3-6 350z have rb26dett and there is only 2 350z have vk56de,i really don't know any shops in colorado that will do the swap that won't try toscrew me out of my money ,but i have found shop in florida that on my350z.com which is a sponsor on that forum that will do the swap for 10000.00 vk56de tune 400 hp and 10000-12000 for the rb26dett price include the motors and installation which seem decent but now the hard part deciding which to do i will probably have XXXXX.xx to spend on the swap and tuning it for alot of power! give me some information on your opinions even though if you want to flame this thread ....getting information never hurts anybody

wall. of. text.


Good luck with the swap though, whichever way you go. I think the vk would sound much sexier.

i would have to agree nice big v8 and most likely i would turbo it

I would go with the vk56 that would be a sick swap if you have the money.

rb swap hands down. cant go wrong with either one though. i just think you will get more power out of a rb motor than a titan motor.(IMO of course)

well i have a month to decide on which motor,i have plenty of cash to do the swap ...vk56de sound great especially if turbo but rb26dett i built to be turbo
so i'm trying to get ideal of which swap instead of jumping into it

lol so you rather pic the lower displacement engine? :icon14:

Id go with the RB26... they love to rev and love boost even more. thats just my opinion though.

how about a 4.2L stroker VQ?

hmmm why not an LSX swap like NOva... all the parts are there for sale to the public.
LS ENGINE= GREATEST ENGINE BUILT.

Are you aware of the kind of internals the rb has and the power its capable of? Im not really sure about the titan motor but its NA so the compression will probably be a bit higher, and if he wants to turbo it then I think the rb would be a better choice.

Personally I would probably just build the vq and bore it to be a bit bigger. Just think you could have a 3.7 before the 370 comes out...now thats different. ;)

lol its like aputting a 2jz on a 350z...
:icon14:

well lets see. theres a choice here. 2.6L or 5.6L, lets do some math.
5.6/2.6=2.15, as in the 5.6 is over twice the size of the 2.6. ok, how about the engine itself?

vk: better engine management, shorter length, lighter block
rb: massive iron block that can handle lots of boost (but weighs a billion pounds)

in the end, you have to realize that truthfully, there is no replacement for displacement.

i have though about that 4.2 stroker and single turbo gt47 but not sure what that will cost me after all the rebuild and tuning, i will have the money to do it but not looking for mass horse power ,just a comfortable number 500-600hp
sure checking my option

also the leaning toward the rb since i can't find any vk internal upgrades

wait, what forum is this?

I've always wanted to see someone drop a VK45DE into a Z

I honestly can't comprehend what the OP is saying since the grammar is terrible.

RB26 is by all means a great motor, legendary if that. Fact is its old technology. The VQ35 is capable of more power than the RB if built right, thats why I opted for this swap in my 240sx. If your going to spend the money to down grade to a stock RB then build it up you might as well stick with the VQ and build it, it would make more sense. So with no question do the VK56 swap and build it up. Torque will be unreal.

lol

btw if you get the vk swap will you be able to maintain ac, powersteering, keep engine rattle down to minimun... ???

agreed, but the onlyy replacement for displacement is a big asss turbo

agreed and nothings wrong with a big ass turbo :thumbup:

Or two big ass turbos

a big turbo on a small motor doesnt compare to a big turbo on a big motor.

I would go with a LS motor if I was doing a swap over either of those motors.

rb been done
go for the vk56

I had a dream last night i wanted to be President of the United States.. brb.. going to create a thread about it in OT and get some ideas

Get the VK. Even the LS motor would be better. There's way too many turboed VQ's, and quite a bit of RB's in the Z already, and going smaller in displacement seems kind of odd.

Wow whats with the hybrid swaps.. 2jzswap, Ls swap... wtf I think thats lame:icon22: . IMHO If you want to spend that money do turbo RB . If you want to turbo that VK good luck I wouldn't do it. RB ftmfw

yeah but i don't want a hybrid! i preffer to stay with a nissan motor!
i'm not looking for huge power really just a comfortable level like 500-600
i do have the cash to do what ever to the vq but sticking fix one to the two motors

i agree too many turbo and supercharge vq nothing special

if youre sticking with 500-600 you can make that NA on the VK, or with a really low boost level, which would mean you get a REALLY useable powerband

i would also like to stay with nissan motor and nissan chasis! no hybrid!!!

well even with the rb26 is smaller displacement it still pushes almost more than the vq
3.5 vq 287hp
-2.6 rb 280 hp
0.9 litter larger than rb and 7 hp more than rb but not bad for smaller displacement

where can i get more information and where did you research this

well umm... if you have plenty of money to do the swap, meaning funds arent really an issue? i would say go with the RB motor swap nice solid build and tune, and get the AWD installed in your car. i believe function tuned in VA can do this for you. How sexy would that be..... AWD rb 350z ^^ now thats something different. just motor is for pansies lol j/p

only reason i say this is because if your planning on a 500+ hp build... lol RWD just spins in first and second... awd you would have much more useable power

that was a no research comment, just based on the general engine layout and what the engine does in its original environment

That would be P I M P :thumbup: :drama: :warmup: :band:

thats because you don't know how to drive

VK56DE
The VK56DE is a 5.6 L (5552 cc) version built in Decherd, TN. Bore is 98 mm (3.9 in) and stroke is 92 mm (3.6 in). Compression ratio 9.8:1.
Output is 305 hp (227 kW) at 4900 rpm with 375 to 390 ft·lbf (509-522 Nm) of torque at 3600 rpm. It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC). It has 4 valves per cylinder with microfinished camshafts and cast-iron cylinder liners for increased durability.


With cast iron cylinder liners it can take some more power with stock internals....raise the CR from 9.8 to 10.5 and a good tune for HP instead of torque and u can get ur 450 hp easy

and that engine runs regular....tuned for 91 or 93octane u can get 500 at the crank easy...

lol your a moron... ask anyone with over 500 HP. take it in first or second, GUN it and your going to spin. yes you can feather it and what not to make it better but your still not putting down full power on the street. with awd im just saying it would be easier. plz dont start pulling out your stupid little Maxima's can run this and that from your other thread... im talking street tire. im not saying AWD is perfect, but just saying will help wit traction at those power levels.

i don't need to ask anyone.. like i said you can't drive.. and if that makes me a moron.. then i'm a moron.. and you still can't drive

RightWD is better FailWD still :icon38:

i'm not going to argue with you.. because we all know the RSX will out handle and out perform a 350z mod for mod.. but the fact is.. bubby over there can't drive.. facts are facts

repost ......

but is not as good looking :D

are you kidding me? girls cream at the RSX-S .. especially since mine is kitted with tints and rims.. if we both pull up a tthe club the same time.. you will see how gets more b!tches :gotowned:

hahaha motegi rims :icon14:

yes... i guess i cant drive.. sorry i dont usually argue online. im glad that you dont ever lose traction on your 500 hp beast...

my RSX is 280.. not 500... anyway.. you should buy a WRX .. park your Z and get some driving lessons before you drive your Z again

don't hate on a playa :icon6:
