VQ swap/2jz swap

[myl3s]

Hey guys i just bought my first s13 after selling my rx7just trying to figure out what i wana do with it/ wat i can affordI know the 2jz should cost about 7gsBut anyone know the price on a VQ swap?

[AZ89two4Tsx]

I'm gonna save you here by not flaming.

Check out the Hybrids forum on here, there's stuff in there. There's also a few threads about both swaps herein 240gen that go into quite a bit of detail. Just use the search button at the top of your screen, you'll find it.

If that doesn't give you enough info, shoot one of those guys doing the swap an e-mail. I'm sure they'd be more than welcome to help you out a little.

Anyways, I'm being nice. Most others would be ripping you a new one right now. Welcome to NICO, and use that search button. Making a thread should come last.

Hi, I'm here to rip you a new one! Nah just kidding, that was the old me. The new me gives free hugs!

Glad to hear that you're considering a VQ swap. It's the future of the 240sx, IMO. Yeah, it's not as strong as a 2jz or RB26, but it is capable of 400hp on stock internals and thats plenty of power. Plus the VQ is super light weight compared to those motors.

Irax and NismoNegro were able to get their VQ35 swaps running for around $5k.

thats for the help, and understanding...hahahah5Gs for the VQ swap isnt so bad i thought it was gana be more

Slow down there, young buck. It was cheap for those guys because they knew what they were doing. I.E. They swapped in FWD VQ35's instead of RWD VQ35's.

Why would they do this? Go search ebay to see the price difference between a Nissan Quest/Maxima/Altima motor versus a 350Z/G coupe/G sedan motor.

A FWD VQ35 costs about as much as an old KA. A RWD VQ35 will have your bank acount thinking you just bought an RB26...

The VQ is a definably the "IN" motor to swap right now. Cheap and plentiful for a newer motor. The transmission is the only thing that will make you dig into your pockets.I'd rock it.

[SR24DET]

I dont know what a 2JZ will cost to put in, but Im thinking it will cost you at least 7g's. Thats if you do it yourself. Now as far as the VQ goes, I can shed some light on that. If you want to use a Z engine. It will cost alot! I almost never find them for less then 2.5k. And thats just the engine. But if you do reseach on the VQ35, you will notice it almost comes in every nissan in the 2000's. So then if you look at there HP ratings, you will notice that the maxima makes the second best HP and you can get those engines for $500. The Z engine is rated at 280hp. The maxima is rated at 270hp. Pretty close if you ask me. But the more you look into them the more different those engines are. The interals on the block are the same. The blocks are actually different. You can still buy a Z transmission and bolt it up, but your motor mount locations will be a little bit more forward then normal. The heads are also different, but you can swap em, or build the maxima head if you want. The Z has a much better intake manifold. I recomend swapping that. Theres alot more to it yet but im not gona go on any longer because this is already a long post. If you want to run a Z motor im gona say it will cost alot. If you do a Maxima swap you will save alot =)

[simmode1]

That is precisely what I was alluding to. I'n terms of power, I've heard that the only differnces between the Maxima VQ and the Altima/Quest VQ's are the cams/intake manifold and the ecu tuning. That makes it easy to match the Maxima's and Z's power. However, the mounting locations for your accessories is different between the FWD and RWD motors. You'll need to fabricate some things, but where there's a will, there's a way!

I plan a VQ swap for my s13 in the distant future as well. If the market is still the way it is now, here's what my plan will be:

-Buy a FWD VQ mount kit (some are available now and some more are still in devepment.)-Buy a FWD VQ for under $700 and a RWD VQ transmission for ~$600.-Swap the heads with a 350Z/G35 coupe Rev-up heads-Use a Cosworth or Injected Performance Intake manifold since you can't use the FWD manifold anyways. Actually, I eventually want to switch to Extrabody ITB's...-Get it wired up and reflash the ECU to operate without NATS.

That's it... in a overly simplified nutshell...

[myl3s]

so wat you guys are saying is that the 5gs does or doesnt include the intake manifold, mounts, etc.?how much do u think the average shop would do it for?Cus i had my rx7 ls1 swap put in for 500...not including motor...obviusly

No, the 5g's does include that stuff. But it's only going to be in the range of ~$5g's if the use the cheaper FWD motor. The RWD motor will cost much more.

Here's what you need to use the FWD motor:

ok so what is required to do this swap you ask?

FWD VQ engineRWD intake manifoldRWD exhaustRWD upper and lower oil panEngine/dash wiring harness from the VQ car you got the ecu and bcm fromNVIS or NATS with key from the fermentationed car My mounts which use the 300zx motor mounts and trans bushinga drive shaftRWD vq35de transmission revup or non revup doesnt matter just needs to be the same generation of VQ since HR,DE,and VR trans are not interchangeable. RWD waterpipesGreffin RadiatorMy shift linkage kit or the guy from vq240z.com's kit he is selling on hybridz.org. A custom exhaustAn ABS source IE an ABS diff or abs spindle to get a Speed signalDakota Digital Converter to convert ABS pulse into speed pulse. To 'smog' the car or ref it and get it BAR approved you will need the catalytic converters from a RWD plat formSmog equipment from the car you took the ecu/bcm/nats/key fromyou may need an IPDM depending on the ecu you use. You will need to upgrade the fuel pump to a 300zx or Q45 or a walboro 255lhrYou will need an aftermarket FPR preferebly a nismo or aeromotiveyou can use a FPR off of a VQ30 but you will need to modify to fitYou need a DBW gas pedal obviously if you use a DBW VQ ECUthe one from the z33 and the 5.5 gen and 6th gen maxima work

LS1 FTW

Sorry I had to say it becasue the LS1 pwns all other swaps.

I don't agree. Engine choice is a pretty personal decision IMO and what makes you happy may not do it for the next guy. The LS1 is great and all, but the motor and transmission are both pretty heavy. And the swap is a shoehorn job.

VQ35 strengths:-some ppl don't like interbrand swaps, -more displacement than CA, SR, KA, RB and 2jz-6spd transmission sourced with ease.-Good horsepower/torque in stock form-less wieght than KA, RB, 2JZ, and LSx (we're talking like, 200 lbs here )

LSx is great. But peak HP numbers don't matter to some ppl. 350hp with good power under the curve is enough for me and is easily within the VQ abilities. Plus I wouldn't want to increase the wieght in the front of my car trying to accomodate an LSx, which is overkill most ppl.

The LS1 only weighs like 200 pounds more over the stock KA and your getting double the cylinders.

From experience i say got with he 2JZ.Ive rode in a 350Z and have a RB25'd vert and the 2JZ pwns all.Like others have said,your gonna pay alot for it but i guarantee you,you wont be disappointed.Heck do a 1JZ swap.There cheaper,and share alot of the same parts as the 2J.

[K3Fallout]

Is the VQ pretty much the only smog legal engine you can put in a 240sx? I only ask because.. well, you can see where I'm from.

[simmode1]

KA = 375-380 lbsVQ = 330 lbsLSx = 450+RB/2JZ = around 500lbs

And the LSx transmission is notoriously heavy. I'm not hating on the LSx. I'm just saying that writing off an award winning motor like the VQ is silly.

And i agree with that as well.One should consider all options,pro/cons before dropping that kind of money on anything.Also if your haveing to worry about emissions then pretty much the VQ is your only choice really.

[GODCHSR]

I love them all... 2JZ has my import heart but the reality is that the LS1 is more bang for the buck and has way more capabilities in stock form.

I'm not saying the others don't have merit, they do but they'll never touch the LS1.

[simmode1]

I am seriously getting sick of hearing about LSx swaps. Not everybody wants that. The OP has already been there and done that. He even had an LS1 in his RX7 and didn't even care to ask about it. GTFO with the LS1 talk...
