because with a 9k rev limit, the gearset in the 6-speed gearbox is about perfect. It's basically for fexibility.
I was originally planning a VQ30DET, but I like the fact that the VQ35 heads flow better, and have VTC, not to mention the option of upgrading to VQHR heads later.

It's been proven larger journals although being stronger can consume more friction. Friction equals HP loss. Us KA guy's are looking into reducing journal size from the cranks to increase rev.
Just like NISMO does with there fully counter weighed cranks.

Here is some use full educational material on how cranks are designed to increase HP.

PoorMans180SX · 04-15-2007, 09:09 PM

True, but are we gonna worry about that minute amount of friction loss on the street? Not really. I guess it's your preference.

KA's are totally different compared to VQ30's, which can rev to 9k.

Rev-up engines were short lived. The New 2007 350z VQ is a whole redesign. Reinforced and strengthened block, lengthened stroke to square up the bore and stroke for higher revs i.e.7500 rpm redline. Symetrical dual intake and exhaust. 309 hp stock. The jury is out on the oil burning issue from previous engines which actually was 2005-2006 engines. The current engines are so new they have not had data back yet, the engine has only been out since January. On paper the New VQ is sick and primed and ready for Turbo or Supercharger.

I don't know to much about the new VQ, is it adaptable and easier to boost from variable compression????.
My boy Dave blew up his 2005 350z when he twin turboed the damn thing (that compression wasn't meant for boost), it blew up before it hit the freeway....He's just lucky to be a fleet manager at one of the nissan dealerships.

twofortyrida1388 · 04-15-2007, 11:24 PM

Thanks for all the info. When I started this thread I was very curious about this swap but now I really want to do it. I have always loved my 4 cyl's but to me it makes more sense for this engine, its light, can rev higher, shorter length and height, more torque and new technology. The VQ as sad as it is to say it has surpassed the RB26 and 2JZ in max hp. The damn thing has hit 1800hp and still rising. 350z's are fast but imagine taking a 1000 pounds off it and then compare. There is a reason the 350z has been named import car of the year. On average how much do you think this swap would be if me and some fellow 240 lovers did the labor and just bought the parts? I know it all depends on luck and pateince but just an estimate.

BigVinnie · 04-16-2007, 12:03 AM

If you and friend did it the swap will cost around $5500. Theres a guy on NICO that just did the swap he charges $7500.....It's not a cheap swap. It's also a lot harder than you think. You have to change out the speedo/cluster, and also program the electric TB, and add an electric foot pedal. You alsohave to retrofit the transmission for the shifter. It's not an easy swap, and unless you are a Nissan tech you won't have all the rite equipment to finish the job.

twofortyrida1388 · 04-16-2007, 12:20 AM

Thanks man. My freinds are the electrical and tuning experts and I'm pretty good with the mechanical. Welding, measuring, a wrench. It won't be soon but I am def going with this swap. I would love to be pushing around 7lbs of boost on it too.

Emp123 · 04-16-2007, 02:48 AM

About how legal is this swap? I know it will pass smog, as its sold in the US, but what are the laws on throwing an engine in a car that is from the same manufacturer and newer? Is there a law (or part of one) that states that the engine had to be sold in the model its being put into for it to be completely legal? (Im in Cali if that matters, and it probably does)

The law states any engine sold in the U.S. that is newer with all its smog equipment is a legal swap. That is California law.

its actually not as hard or expensive as you're making it out to be...
VQ's can be had for next to nothing. i've seen maxima VQ's go for extremely cheap... if you got the interest and drive to do the swap, i say go for it.

the easiest way to get a VQ into a s13/14 is:

standalone engine mgmt
convert to mechanical throttle body
weld bellhousing from vq tranny to sr/ka tranny and bolt to VQ
bolt in engine using 33 GTR engine mounts
convert speedo: http://www.engineswaptech.com/forums/post/744.aspx

i can understand wanting to run the 6sp, especially since they can be had for only a couple hundred bucks, but it does require shifter linkage modification, custom driveshaft, and tranny mount, which complicates things a bit.
KA 5spds are plentiful and cheap. it probably wont last that long, depending how you drive it, but you can always swap another and it makes the swap alot less expensive.

twofortyrida1388 · 04-16-2007, 12:06 PM

If you are from Cali with their crazy emissions I understand but here in NC nothing is a problem. We are basically givin inspection stickers.

But wont it like not pass the visual inspection? Or are they just checking to see if there are any turbos/all the emissions stuff is there?

Emp123 · 04-16-2007, 02:35 PM

The more I look into this, the more I want to do it.

PoorMans180SX · 04-16-2007, 03:01 PM

Heck yeah man, it's such a sweet option that everyone overlooks. For a budget swap you can use a VQ30 out of a Maxima, with it's easier-to-tune ECU and mechanical throttle body. Look up Broaner, he has the first VQ(30) powered coupe in the States. I'm surprised he hasn't chimed in already.

O.k so what engine management would he need to run that isn't over a grand, it would make the build more expensive, than using all the existing OEM equipment and ecu.....

FYI here is the the entire build Spec D racing has done....
It's finished now..

If you care to argue pricing and standalones, open a new thread for that. This thread is being posted to show how to do the swap with the Z ecu, make it run, and do it without a dyno. For 99% of the those reading this....this would be the way they would/will do it.

Again, your input is never unnappriciated, all input is good to show others different prespectives.

Emp123 · 04-16-2007, 08:11 PM

This swap looks much more complicated than a SR swap, but the power gained is crazy.....if only this swap brought a smile to my face like the RB25DET/RB26DETT swap does.

twofortyrida1388 · 04-16-2007, 09:33 PM

I love the RB's and all the 4's but this motor will get eaisier and easier the more it is done. Shit it is just as light as the KA but makes twice the power. The RB26DETT is godly and a beast but the VQ35 is lighter and makes just about the same power N/A (05' and up 350z,G35). You do a basic turbo setup and you got a beast. The center of gravity and 50/50 weight ratio with VQ35 will be better than RB25 and 26 because it sits lower and further back. There are some people already making a custom linkage for 6MT to sit where the KA's does. Thanks for all the input it makes me glad I started this thing.

twofortyrida1388 I totally agree, but theres something about having a Skyline engine that makes me really happy. Despite this, Ill probably go for the VQ. Awesome power, awesome weight, awesome price.

Still isn't cheaper than an OEM ecu for $100. Plus like the man said that did the swap. OEM is gauranteed to make the power with no dyno tuning, you can start adding up the cost if you like. OEM is the cheapest route.....

brainfood · 04-16-2007, 11:13 PM

Couple missconceptions in this thread that should be clarified.

VQ will not give you a 50/50 wieght distribution. If it wieghs a little more than a ka and we know the 6sp wieghs more than a ka trans. Even if it lower and pushed back slightly ka cars are usually 58/42 Even sr cars are only 54/46 most of the time or at most 52/48. If it keeps getting repeated in this thread that going VQ will give you 50/50 then it will go down as the word of god on internet forums even though it is a false statement. (if someone has a vq powered s14 and wants to prove me wrong please put it on the scales I am dieing to see it)

Also using a ka or sr 5sp is not a better option than using the 6sp. If you have to cut and weld a custom bellhousing how is that easier than cutting and modifing the linkage. The modifications that I have seen done on already swapped cars with z33 6sp doesnt look that bad, I would lots rather do that than Cutting and welding a new bellhousing.

Drive by wire should be eliminated for this swap into an schassis, there may be running drive by wire cars out there but its overcomplicating the swap. Just get a tb that is cable driven and make a custom bracket its pretty easy. Other than that awesome swap and anyone has done it I aplaud because its a pretty badass swap. I cant wait to see a built vq32 n/a monster locally so I can drive it

Kyosuke · 04-16-2007, 11:17 PM

Emp123 · 04-17-2007, 01:57 AM

I saw a video of that thing revving, it didnt sound to good, which is surprising because the engine sounds really clean in the G35/350z

no doubt it cheaper... but is it worth the hassle installing the NATS system and associated immob bullshit? can you say wiring nightmare? good luck getting it all going without a Consult II. I'd rather just spend a couple hundred more for a fully programmable system and bypass all the bullshit.

no, the 5sp is not the better option, but it IS the easier one. using the 5sp allows the VQ to bolt right in. meaning no custom engine mounts, no custom tranny mount, no custom drive shaft, and no modification to the shifter position.

found these guys the other day: http://vqswap.com/index.html
they make kits that address all the problems above and are also working on a plug and play ecu solution

PoorMans180SX · 04-17-2007, 10:04 AM

sick link bro! posi! I'm pretty darn sure you'll still have to use custom engine mounts with the 5spd though.

PoorMans180SX · 04-17-2007, 11:03 AM

Pics of their swap they sent me. I think I'll mount mine a little farther rearward, but looks pretty good.
