What do you think or has it been done? After all why not try to go with na power and swap the old 4cyl 2.4 truck motor for the VQ40 V6 4.0 Frontier/ Pathfinder motor? The VQ40 is just a stroked VQ35 with a different intake setup. And the Fronteir has a 6spd transmission. Isn't that supposed to be the same transmission as the 350Z?

Just a thought

I looked into this a few months ago. This and VQ35/VQ40 frankensteins... There are some detailed research on a Maxima forum I found (thread started as a Maxima swap thread into a 240 swap thread... lol).

http://forums.maxima.org/all-m....html

I haven't found anything conclusive yet, though. But hell... people still don't have the VQ35 swap down smooth yet, so I dunno...

I've heard this place may be helpful, though...http://www.engineswaptech.com/default.aspx

Thanks simmode1, from what I gather is the block height is different than the VQ35, maybe. I still would like to try this or see it done, I think the VQ40 would make a powerful & reliable swap. May need a different hood tho.

There are a few VQ swaps that have been done on here. Most are VQ30 and VQ35. But the VQ40 is just a variation of this. Increased bore and different stroke.

I forget who, but someone is using a supercharged VQ. I think its a VQ35 with the VQ40 supercharger.

I have always wondered about a VQ40 with VQ30 heads on it. Possible high comp VQ motor. Maybe add nismo cams.

The stillen supercharger on the VQ40 in the 240 would be an absolute torque monster. I'd prob want to just go the n/a route. If the VQ40 can launch my 4800lb. SUV to 60 in just shy of 6.5sec it would be killer in a 2800lb. 240.

Well, The motor mounts would most likely be the same as the VQ35 mounts. The hight of the motor will be a problem because the VQ35 already has a hood clearance problem. Not much, but a little. The car will still need a custom driveshaft, exhaust. You will also have to shorten up the transmission. If its the 6-speed RWD transmission then yes, it is the Z transmission. If it is the AWD one, then it is obviously not the same as the Z. Once the motor is in and all setup the next and hardest part will be wiring it up. The throttle body wont be a problem because unlike the Z, the pathfinder isnt drive by wire, its a regular old cable throttle. But the car still is an OBDII and it also has the VVT. This creats many problems. If you stick with the stock ECU, your gona have a nightmare. You will need the key of the car that came with the motor along with the ignition switch. Also all the sensors need to be wiried up or the car wont start because of a secirity system nissan put in the ECU in 2000. If all the sensor arent hooked up, the car wont start. This as you can immagine would be a huge pain in the @ss. Now you could take road 2 and go with a stand alone. If you get an expensive one you shouldnt have much of a problem. If you go cheap like MS or MSII. Both of these dont control VVT so you can do it, but it will make you lose alot of power. If thats your choice, I wouldnt recomend doing the swap because of the ammount of power you would lose wouldnt make it worth it. If you wana do it the way I'm gona do my VQ35 swap, you call Jim Wolf Tech. They will ask you to buy a 96 Maxima ECU. Then you send it to them. For 5-600 bucks, they will reflash the ECU to work for any VQ motor. You tell them what you want they will do it. I asked them to reflash it to work for the VQ35 out of the Z. I wanted it to work with the VVT. That was it. No emmissions. No other BS. This way it would not need all the sensors. No security system. Nothing. Easy plug and play setup. You still need to run the wires but that shouldnt be a problem. They also have a wiring diagram on there website.

Feww... sorry that was alot but i did alot of research to do the VQ swap and because i have to wait to do my swap, I wanted to share.

^^^ Are you going to use VQSwap.com? Or are there other resources besides them yet? I've heard that other people are also working on better and more complete swap kits...

You mean VH45 or VK45, right?

Thanks for the input . I was thinking of getting the VQ40 & 6spd transmission out of a '05-up Frontier 2wd. And youre right it would def have to have a stand-alone ecu. The problem is the VQ40 in the Pathy, Xterra, and Fronteir are drive by wire (at lest I know my Pathy is). It seems like it would be too much of a PITA to make it work, but it sure would pay off if I got it to work right.

simmode1 - No, I don't plan on using VQSwap.com. Not only do I think they are way over priced, I also havent heard to many good things about them. Alot of people that have tried to use there swap have said there are some fitment problems. I was going to either make my own mounts, or there is a group buy for the mounts here on nico. Some guy will make em if there is enough people.

Salem240 - I tired looking for the site that I found that had alot of info on the VQ35 motor in all the different cars. But there are some VQ35 motors out there that are cable throttle. If you email Jim Wolf Tech. they will answer you but it will take a little while. If you call them you will get in right away and they are full of info. I called them and talked with them for a while. They specialize in the VQ motor because they build alot of dun-buggies and they are all powered with the VQ35 motor. Thats how they have the wiring diagram and all the ECU modification abilities. Awsome people and they are very nice.

^^^ Thanks for the info I'll have to give them a call or email. Hopefully I'll get enough input so I can see if I could make a swap like this work. Hell, if I can't than I can still just go with the VQ35, I thik it's a great motor. Either way I'd like to stick with n/a power, I like the predictable and linear power of the VQ .

This may help a little more. From what I can gather the VQ35HR and the VQ40DE have the same bell housing so I "think" that means you need the transmission out of an HR equipped Z/G?
