Default VK56DE Motor Swap?

Can it be done? The VK56DE is the V8 engine that comes w/ the Infinity QX56. -Not that I want to do this swap, just extremely curious.

Anything can be done with money.

You won't get any knowlegable responses here unless C.Forsberg chimes in who has done the swap. He probably knows everything from A-Z on the swap.

My Z could fly. Fly in the air.... if I had the money, I know... Maybe I should revise my original question. Has someone done this? tell me about it if you have.

I believe only Chris Foresberg's drift ZR is the only known Z to have done this swap...

Doing this in the Z wlll require quite a bit of work in order to have the engine sit far enough back in the engine bay in order to get a decent weight distribution but it is definitly possible. The costs of such a project can range from a very manageable price (if you have the capabilities, resources and knowledge to do the swap yourself) to in excess of $20k if you have to have someone else work out the bugs.

How about the 4 liter VQ in the Nissan Pathfinder?

Same engine with a lot more displacement...

Is that really an efficient engine? I dunno to much about the 4.0 but I know it is only making like 270hp and 270tq or so? How much more power could we get out of that? Besides won't it be cheaper(and better?) let say to get the vq in our engine and bore it to the 3.7 like the rumors that are going around to the 4.3 that is out now?

That or just put better internals into a 4 liter block.

An LS1 would be nice too it may not be practical. It will be very interesting to see what happens with the LSX.

I looked into this awhile back I say definately, however wiring on any of these swaps is gonna be teh suck.... and then you'll need to spring for a standalone with all their little add-ons, and still won't have much more hp unless you add on money for internals and bolt-ons, blower, turbo, etc. In the end you'd have an easier, cheaper time with the vq35.

...now if we had a rotary in there, get the LS or VK swap!!!!

Unfortunately, the money for a turbo is not going to get you too close to a full motor swap.

Thought you were dead set on GTM and a turbo Shane??

I thought I was too.. I guess now that the time has come to make a real decision, not just talk about it, I'm getting a little nervous that I won't be satisfied in the long run. I'd like to hear from others experiences and exhaust all options.
