just throwing this out there

:yum:

LSx swap would be better imo.

yeah and i said F the LS.

Definitely the LS would be worlds better, but it is kind of cool fitting a Nissan V8 in the Z.

Very cool just like Forsberg's 370 in formula d

I think you are being a bit conservative on the additional cr@p, but who knows until someone does it.
Would love to see a Nissan V8 instead of another LSx build, but the fitting the Nissan is going to be tough.

Anything besides a Nissan motor is sacrilegious

Yeah. Unless you value your time at zero.

I agree 100% as far the coolness factor, keeping it Nissan etc. Sh!t, y'all know how much of a nissan fan I am. STILL, if performance is your goal, the LSx swap makes worlds more sense. If you are just trying to be cool and have a "one off" type car, then absolutely, the nissan V8 is the way to go.

Either way will result in one bad *** Z regardless. :tup:

Yup!

All that work and money for what? Get a turbo

I think of it less as a performance improvement and more of a car improvement(like buying a nismo)

all that work and money is for a motor that would be much more reliable with a closed deck block and a proven performer that is normally coupled to crappy automatic which is why you don't see huge titan power levels and why the stillen supercharger puts out "only" 440hp and 450ftlbs (over 400 from 3300-5300). the factory motor can push more than that (and well over 1khp with new pistons,rods, and headwork) when coupled to a tougher tranny, that won't smoke every clutch in it after 10,000miles like the slushbox does.

Menard racing pumps 790hp NATURALLY ASPIRATED out of a stock block vk56

The REAL NISMO JGTC cars used the the vk56 as well as the JGTC GTR's with flatplane crankshafts and rotating assemblies

They sound BITCHIN

as for the LS swap people it is not just for the NISSAN factor, a cammed VK56 can make as much power as an LS2 while making more torque in the process

Also no more PITA nissan ecu compents you could probably save more than the 80lb weight difference between motors just by getting rid of the damn computers and factory boxes the aem unit replaces. I would end up re wiring the car so that no "ice-mode" "throttle delay" "power cuts" "limp modes" and other "worst idea nissan ever had" 's would ever come up.

Sounds interesting! Hope you build it!

LS3 or LSX > vk56 all day I do not believe in Japanese v8's never did never will

Yeah, awesome at the next emission scan...

None of these solutions will pass emissions without some palm greasing.

of course there are states that dont care....

25k trade in on a 370z, used gtr 60k, much quicker and less painless

like where i live? we don't give a **** about emissions, i used to have a firebird with just headers and i got a fix it ticket all i had to do was put on mufflers to make it quieter no cat's signed off with no palm greasing required

also F'n haters

You seem very angry.

hopefully i'm going to have the motor next month, want to start tear down and refresh what i can for now, super limited budget so we'll see. Looking like a full strip and rewire for the entire car everything will go, abs isn't useful to me so its out, going to see if we can't pull a mile of wiring out of the car (real goal here) will be using aftermarket traction control, going megasquirt 3 with ms3x expansion for full sequential fuel and timing, hand built headers and mounts, neo garage adapter plate+clutch or make my own, new guage cluster using analog style gauges, gps 200mph speedo, diy manifold maybe itb's we'll see. going to use an 04-06 non cvtc engine, custom trigger wheels, use the factory coil on plug setup, need two ignition modules to fir them from the ecu, going to soldier up an in dash knock light/headphone jack for tuning. Going to focus on getting it running by next spring if i can get all the parts in by fall. going custom oil pan for now unless something happens where i can get my hands on a drysump. hopefully i can keep ac, might need the room for something else. going to call it project "simple" I'll break down all my costs as they come up knowing i may not be able to make this happen quickly so don't hold your breath. once i get the motor in i'll fire up a journal thread. hp goal right away is to not make any less than a stock z, down the road gonna shoot for 600. If all goes well maybea build and cams, a turbo or two since the ecu is built for it, fuel-cell/return system, a small cage hidden behind a hand layed carbon replacement interior to lighten things up a bit, move the battery to the back, 4 or 5 point harnesses, then the really expensive task brakes, suspension, and custom bits like active brake cooling. i want to be able to drive it to work, have it unique and functional, hand built but not cheap looking, and something i can keep working on for years. If i don't have a motor by march just forget about it.

Edit: oh yeah the goal is to get the motor in and be able to drive car for under $6000/ i realize i said going 8 times.

:iagree:

Event tho it will be a an awesome build! good luck!

yeah but much cheaper, paid in cash

Ambitious and very cool project -- good luck! Keep us posted :tup:

this still happen?

Hopefully you document this well!

This idea sounds interesting.........sub'd

Youre my hero, i allways wanted to do that even before Cris Furenswhaever got his monster. I am definetly following this one plzplzplz post progress.

For a moment, I had a flashback to NICOClub. LSx this and SR20 that, lol. You typed what I was thinking

<on-topic>

A VK build is exactly what the doctor ordered. Now we just need to find the right manual transmission to mate it with. Then hope that it lines up at least close to right......

i will be using the factory 6 speed just ignoring the synchro rev sensors(unless i can pull something off in ms3). They make adapter plates for them to bolt to vk's it's like $700 otherwise i'll make my own and spend that 700 elsewhere. Filing taxes tomorrow then going motor shopping.

Edit: also this would be the 3rd time. Chris Forsbergs mechanics, Ryan Kado's mechanics, me(iff), i say mechanics cuz they did'n do sh!t

:barf:

i swear i'm gonna pistol whip the next person that stuffs an ls into another car. i think its time we start looking forward in the customizing world when we want power instead of using the default "shove an ls in it"

But that's the American way shove America in it and it's 10 times better...

I always laugh at the ls projects cause as soon as it's done it's up for sale!

there's a guy in australia building a 2500hp vk56 slingshot ls's aren't some god king of the v8's, theres just a lot more of them, factory installed in sports cars, without truck manifolds and cams. the tech in an ls is 60yrs old at least ford finally went DOHC

Edit: will be buying motor in next couple weeks have money set aside so its a go. found a replacement for the intelligent key/ keyless start to rewire the door locks and add a nice alarm even remote start should i dare install one on a manual. the main boxes will be ms3, viper 5701 + custom built relay and diode board for doors and push start, racelogic traction control, standalone gauges, and painless or junkyard re-purposed fuse/relay/breaker box. I might wire 4 switches together as a simple 4-bit key combo on dash to start car too, as in flip the four switches to certain positions in order to power start button.

The wheel.
It needs to be re-invented why?

and you think this is because it has an American engine? I have seen FI 370Z's change hands so fast on this board that someone accused the seller of trying to sell someone else's car, lmao

Cool story and all that, but the LS7 is still king of the NA V8 motors under $40-50K in price. Mercedes has one in their AMG car that makes about 50-75hp more IIRC ...and costs about 300% more.

DOHC isn't all it's cracked up to be. The 5.0 Coyote is a great engine, but it weighs about the same as the LS7 and produces far less power, especially at lower rpms.

GM experimented with DOHC designs and stuck with cam-in-block for a reason. These reasons have been detailed again and again and again, but suffice it to say when you have a 450# motor complete from manifold to oil-pan that will make over 500 horsepower and pass emissions, you have a winner. Now consider that it will produce over 500 horses at the TIRES with exhaust and a mild cam and a tune.

Technology is great, and I am sure someday it will bring us an engine lighter than the LS-series that can produce more horsepower, but so far it has failed to do so within 2-300% of the cost of the most expensive LS-engines available.

One of the reasons the LSx is so popular is, easy/cheap power, it fits any almost any engine bay, and did I say cheap/easy power?

True...

The LS swap is awesome, but the VK would be cool to see. Personally would wonder if the GT-R powertrain can be shoehorned into the Z like they did with the Juke-R.

Anything is possible, with money, but the main issue with that in a Z is you will have to prep the front end for the power. Since the car is designed for RWD you could potentially twist the front.

Then you add in the light weight and it is a no brainer. A ~400lb engine does a lot less to upset balance than a 500+ lbs monster.

I would love to see this. Not really familiar with an 7 engine swaps.
