Vk56 R34 Gt-R

[CosworthSti]

I've seen alot of 350z and G35 owners and others do the VK56 swap and it's a great engine. My question is can you swap a VK56 into an R34 without replacing the transmission. I don't mean can it handle the power and torque, I mean can the gearbox actually bolt up to the engine. It would be amazing if the VK56 can bolt up to an R34 GT-R and keep the AWD while having the VK56. So what do you think guys can this be done...?

I asked Robbie Ward if a VK56 would fit in a skyline and he said that it would be to wide and wont fit easily in GTR engine bay. He has one for his new rail car and said these are massive compared to a LS1

i highly doubt the GTR box would bolt straight up the the engine. at bare minimum you would need a custom bell housing.

lets not mention where in the world would the front diff go?

[CosworthSti]

yh haha I think I underthought this idea haha if anyone can do it Robbie can. I just thought it was a good idea since I've seen these engines being thrown at everything and they're good engines. i think the front diff thing would pretty much kill this idea would it not?

[Cowboy1600]

What's wrong with, oh, I don't know, an RB26dett? I've heard they are pretty good engines, too.

Anything you aim to do with 2.6lt can be more easily achieved, be more reliable, and will be less stressed overall when its done with more displacement.

[StevenCJR31]

A VK56 in a 34 Gtt-t would be a better proposition( lighter all alloy engine?) no headaches trying to get the GTR 4WD working

Just just think how much fun a twin turbo VK56 would be.... or stoke it to 6lt first

Not for the money.

Spend $30k shoehorning a VK56 into a GTR and you'll have a bog stock VK56 in a GTR. Spend $30k building up an RB26 and you'll smash the living shit out of your stock VK56 engined R34.

Not to mention the aftermarket support for RBs is probably 100 times larger than that of a VK. Sure, when money is no object, go nutso. I'd do some crazy conversions if I had millions, but just because you can, doesn't mean you should.

[Gerg_R31]

Vk56 at its widest point is 26.5"

these only came out with an auto behind them

There is also the reluctor wheel mounted to the flex plate

there is an adapter plate and clutch kit available off the shelf to match a 370z manual

there is also the height, custom manifold defiantly will be needed

there is also the sump which holds oil vertically at the rear of motor, instead of the horizontal like the RBs (this was to fit the front diff in front of it so it would fit in the Nissan titans

On top of that, not much room for the turbos

they also came out at 9.8:1 (some with corn based eflex)

2007+ = cvct

timing chain also has been known to jump at high revs

US guys claim 17mile/gallon with their n/a

Ecu? 370z use same computer

pistons Google gtm

cams Google Jim wolf technology (s2/s7 s2vct s8 or s8vct most popular

(costs

2k long motor

1k 370z box

1,200 adapter plate

1,200 flywheel/ clutch kit

1,500 cams

300 springs

2-3k importing costs

1,200 pistons

6k stillen supercharger kit

then once here 5k+ fabrication

End result probably around 450-500hp

edit;

Just noticed the dates, sorry for mega post bump lol

[C4a0s]

personally i'd prefer to heavily mod the RB than to fit the VK.... in fact there's already proven records of 1200hp RBs so... why go to all the hassle of putting a stock VK into a GTR?

[Hillstc]

Mega bump and my first post in maybe 5 years but yeah Robbie Ward is right, they are wide as hell being twin cam and all, but they do fit. Google Ian Fournier.

I've got a high comp atmo VK56 in my R32 sedan drift build.

The tightest part was the clearance between the strut towers and the exhaust ports.

Ended up putting in an S14 steering rack for better clearance and getting a custom steering column made to change the angle on the universal to give more room.

Also ditched the brake and clutch masters, running a floor mounted pedal box with remote reservoirs instead. That part isn't essential but I wanted to mount the engine as far back in the engine bay as possible cos racecar.

Custom tunnel etc. Got photos if anyone's curious.

Putting one in an R34 would be fairly similar I would imagine, but forget AWD, if you wanna go big get one of robbies 4wd RB30 long blocks. Be way cheaper in the long run.

Turbo is impossible then.

Vq37dett might be a better proposition...

Or just vr38 swap

[KiwiRS4T]

VH41 is possible. There is a thread on here somewhere about putting one in a Stagea with a Manual AWD box. Must dig out the thread and see how its going.

[sneakey pete]

Yes, it's a front mounted turbo though. I mean more low mount twins ala 300zx/r35 style, sorry I didn't clean that up

[WHITER33GTS-T]

Double unicorn on YouTube was a turbo v8 stagea

[KiwiRS4T]

Good job. I want the car. Needs more power though - 330AWKW is just a rough and ready RB30 or a mildly modified RB26.

Not saying you're wrong, but it is daily driven on unopened motor with fuel supply issues. and an 80's Jap V8 engine to boot.

I'm not saying 330 awkw is not a decent lot of power but it just seems (in my opinion) a barely adequate return for the huge amount of time and money that has gone into this (well executed) project. And of course it needs a better fuel supply. The owners seem happy with it and that's fine.
