Swap A Vq25Dd For A Vq35De


Recommended Posts

Hey Guys, probably sick and tired of my questions, I’ve got a mate that’s just totalled his 350GT, engine bay was untouched and al is in working order, he will give me the engine for 300 dollars, which seems like a pretty good engine, he’s only done like 60K so far so it sounds pretty good. I know the installation will be a large cost but will there be many complications, I know the ECU will need to be swapped out, but is everything else in the car fairly similar? if anyone has done this before let me know.

Cheers.

You'll have to replace and splice the loom and plugs with it. It's not as easy as swapping the motor in.

The you have the issue of the 4spd tranny vs the 35 which runs a 5spd, which might mean headaches.

All in all, it's better off to sell up, and buy a real vq35, it's going to be cheaper too.

Lots of headaches. You would need to swap every ecu in the car along with the 5 speed auto. Better off going 6spd manual and a Haltech with the 3.5 conversion imo.

There are more differences than you would expect.

You clearly didnt do your research before buying and it shows by the posts you make.

if the OPs post is correct, he hasn't bought anything yet. He is doing his research..

No purchases have been made, just asking, I’m not a mechanic, so I don’t think it’s unreasonable to ask questions. Obviously I’m just curious and if cost outweigh benefit than I will not continue to look into this. I don’t see a problem with being curious, and as I mentioned I AM NOT A MECHANIC! If I was then I wouldn’t be here would I?? Just something to think about before hurling your abuse at me. I have little to no car knowledge, hence why I am asking questions so I can learn and hopefully help others one day.

I bid you good day Sirs.

As far as this thread goes, there has been no abuse hurled, what's your damn problem? We were only offering advice like you asked for... And it has all been asked before.

I AM NOT A MECHANIC!

I fix these cars for a living, and yet here I am, helping an ungrateful V35 owner yet again...

    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!  
    • As far as I know, Infiniti stopped importing vehicles before 2020, even though they were still selling their stock for at least a year or 2 after that, they were older build years, therefore, you can import a 2020 400R, because you couldn't buy an AuDM 2020 built Q50 RS. As for insurance, you might need to go through one of the enthusiast insurance companies, they tend to insure a lot more grey import models than the mainstream insurers as Duncan mentioned.
    • loved seeing the zenvo on the a1 just after the hatfield tunnel i was the guy in the white van trying to egg you on it sounded awesome and those exhausts glowing red inside insane cheers for the thumbs up tim and tom.
    • So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.
    • Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.
