Im listening

:bowrofl::roflpuke2: right!!!
It's one is the techs car. He works on it every Saturday so keeps making small progress all the time. I will let ya know when I stop to check on the car in a few weeks. But seriously it looks like it belongs in there. So.......beefy no homo

Oh a little off topic but Lohit was awesome to deal with on the fenders and hoping to have them test fitted on the Z by the time I go check :tup:

So are they (GTM) making a kit or what? Lohit will take care of you for sure. Dont forget to post pics when complete :happydance:

i've seen a pic of said 370z with a vk in it. looks sexy as hell :excited:

i would say this video makes GTM's plans clear.

I like it!

:excited:

i would love to see a true Z34 with the vk56 in it, not just the shell of one chris forsberg is driving in the drifting circuit

Looks like a Haas VF8 CNC from the inside view on the video.. Nice.

that's definitely sweet for sure

well I had things come up and I need to sell my DD and drive the z for a while so I'm gonna slap a pepped up 6 back in there and call it a day for now until i can take it back apart again. Oh and the current status of it before i stopped was motor in, accessories figured out, mounts and exhaust done, just down to intake manifold, wiring, fuel, oil pan, forced induction, and then all the finishing work.

Dude no! Buy a beater to DD!!!!

:iagree:

any pics of the progress before putting the 6 back in?

agree

I'm bringing this thread back from the grave. Definitely interested in pics of everything as well as info on the custom work done.

Shoot me a PM if you've got time. Kinda considering this swap.

Nice bump this started to slip my mind.

We can't let the thread disappear forever. Once we get the swaps started it will catch on

It came down to cut up the firewall, or make a shorter upper manifold, neither of which i have time or money for right now. The project isn't dead but it is close. Right now I dropped the car off and I'm having the v6 fixed up and put back in, and working on some of the support stuff. Getting the head gaskets changed and doing some exhaust work, last i checked it is right around 320hp@6700 and 280tq@4500-5900 and still needs to have cams, heads, exhaust, e85, and tune done. Suspension, clutch, brakes, body, aero, maybe seats, possibly cutting weight, drysump, surgetank, crazy ****, all of it is on the list to get done, or is already done, so once I finally put everything together it is gonna be nukin futs v8 or not.

I was jumping in the office when I saw the thread bump. DOH! sub'd for the long haul :excited:

That sounds like a crazy setup. When I was reading through everything it sounded like you were going to hold off on the v8 idea but go with some sort of FI (I could be incorrect about that). If I'm not wrong is that still in the works until you get everything squared away with the vk engine??

Fi is not out of the question, i have been thinking about a little something, maybe a small insta boost turbo for 450-500hp

the heads are probably going to get worked over, port polish, jun stage 2's maybe a little something xtra ;)

The idea of the small single turbo is a great idea. One idea that seemed like something I'd consider would be a twin turbo setup with 2 different sized turbos. One small for that instant boost and another larger one for big power up top

:yum: that's gonna be sweet

just like the BMW and Audi bi-turbos lol

Yeah exactly. I wonder how a twin charger setup would work in the Z

not sure. you'd probably need the input of someone with more boost knowledge than myself lol

Sequential twins would be pretty sweet. That would be an interesting take on FI for the VQ.

Sequential's are kind of a pain in the **** because there is a lot more to it than just putting two different sized turbo's on it. you end up needing to add in exhaust valves and intake valves, and a way to control them so that when say number 1 turbo is spooling up the air isnt just blowing through the larger number two turbo's compresser housing backwards.

It's called compound turbo charging and is done all the time in the diesel performance world. It has also been done on OTR heavy haul truck engines. Cat has a setup like this. There is also tripple compound turbo charging. Turbo sizing is key to keep each charger in it's map.

Or you can buy one of Porsche's variable turbine geometry turbo's and call it a day.

Yeah no... I dont really care anyway anything past 500hp is worthless to me at this point. And vgt turbos have reiability issues

I'm just jumping in here, but this conversation got pretty interesting. I am looking into possibly swapping a VK56 into a Y34, but for the Z guys, why not the VK45 instead of the 56? Seems like it might be a bit easier and should still make plenty power.

no compound or series charging is when one turbo FEEDS the other turbo. They use it in the diesel world because by doing so you stack pressure ratios. so if one turbo can efficiently compress the air to 39psi absolute it feeds that charge into the second turbo that can push it up to 109psi while still in it's efficiency island. Diesels love having more compression so by doing this even if the turbos are relatively small it allows the engine to run at a much higher dynamic compression ratio.

Edit: the key in sizing doing that is just to match the pressure ratio's and efficiencies of the two turbo to get the target boost pressure, and to make sure that the intake turbo can flow enough compressed air to supply the second turbo

The VH45 is no bigger than a stroked vq so by going vk5.6 you have enough extra displacement to really make a crazy build worth it. the vh is good engine, revs higher than a vk stock but it is a little small to justify it.

You're correct, but I'm referring to the VK45, not the VH45.

same deal. since vk45 and the vk56 are basically the same engine but one is bigger, cheaper, and more available the choice is easy.

Subd for later!

Well the platform changed a bit but same swap. its going in the 260z now hahaha. got the motor for 1500 with low miles, picked up a freshly rebuilt vortech v1 s-trim for 300 dollas and the trans came from the donor car for the 350z subframes. Still need a clutch and flywheel.

also the vk to de trans adapter is done already just need some more dowel pins and then get a vq35de flywheel and clutch so i can check the engagement of the friction disk and starter and make a block to use the vq starter mount to the trans.

That is going to be absolutely beautiful... Wish you nothing but an easy install!

Almost 5 years later and its finally coming together huh?

Well i started the first time in the 370 but the project floundered when it was at gtm so i ended up switch to doing the full NA build on the v6 which made 371rwhp and then sold that car chaned jobs settled down a bit and now im restarting with the 260z which is a pre smog year so it just makes more sense anyway.

Glad your project isnt totally dead, rusting away in some garage. I'll be excited to see it in the 260. You could get some badges made up that say 560z lol.

Let the dreams come alive!
