How to tell apart 350z/G motor from the other lower performance VQ's ??

Postby redsx13 » Wed Aug 12, 2009 10:32 pm

I just blew the motor in my 350, so I'm in the market for a new motor. The question for my fellow Nico members is when I find a new motor how can I ensure I'm buying one out of a 350z, and not a detuned version out of another one of nissans cars? (engine vin maybe) The last thing I want to do is rock a Nissan quest motor in my z. haha. My second more envolved question (not that I expect anyone to know for sure)is, is the HR a straight swap into a non-hr z, plug and play? I'm guessing it's not, but it doesn't hurt to ask.

On checking out the differences in motors, I would look for one with the "Z" plastic cover that goes over the intake manifold. That's about all I know on checking out the differences lol. Maybe also engine mount locations to make sure it is not a FWD VQ.

And no the HR would not directly swap into your Z. You would have to get the HR wiring harness and ECU.

Engines don't have a VIN number, they have a serial number. If there's a "serial number decoder" similar to a vin decoder/key I've never seen it. That doesn't mean its not out there though.

If you're looking specifically for an HR you should be able to spot one compared to a normal VQ almost instantly.

And I'm wondering, how did you blow the original VQ?

YHmm, there has to be another way to tell the VQs apart. most of the engines I have seen for sale don't have an engine cover anymore. I know the FWD vq's have a different plenum, and might have different exhaust manifolds, but I'm not sure. But I have no idea how to tell apart say an Infiniti g35 coupe (293hp) and a g35 sedan (265hp).

My original motor bent a valve which broke off and fell into the cylinder

You can spot the difference between a VQ35DE and the VQ35DE Revup by the front timing cover. The Rev Up has variable cam timing on the exhaust and intake, whereas the non-rev has variable cam timing on the intake only.

I appraciate the responce, but maybe you misunderstood my question, I'm not talking about the vq35hr vs the vq35de, I'm talking about how to spot the differences in the 2003-2005 (06 maybe) vq's, pre rev-up, motors.

If the person selling the engine can't honestly tell you what vehicle it came out of... I would find a different seller.

I was trying to warn you against buying a RevUp. They had oil consumption issues from the factory and can typically be had for dirt cheap. Lots of folks buy a RevUp not knowing they can't transplant it into their '03-'05 without swapping all the electronics/wiring.

I think the issue is whether a VQ35DE non revup from a FWD Nissan is the same as a VQ35DE non revup from an early G/Z/FX.

or could just skip the hassle all together and get a vette engine. you could get an ls1 pretty cheap, prolly and ls2 as well. or go all out and get an ls7 which is a powerhouse of a motor if you were interested in doing some type of swap like that

I'd get a shop to swap in the VQ35HR and turbo that B!*** if money weren't an object.

Sure they can tell me what it came out of, but it doesn't mean they are telling the truth. If u have no way to identify, then you will never know for sure.

Guys, I appraciate all the input, but some of your comments don't answer the question a all. If I have the time and resources I would swap in an LS2, but I don't. A turbo will come later down the road, but for now I just need a reliable VQ

Get a hold of SteveTheTech or Poyzinous here on the forums and ask them. They're both Infiniti Techs and should be able to tell you what if any difference exist.

GTM in Rancho Cucamonga is working on a DE to HR swap in a 350Z. I'm sure they can steer you in the right direction

I have an idea. How about screw the VQ and you get a VG30DETT instead? Does 700hp on stock internals sound good to you?

I have a better idea. Keep your replies on topic so I don't delete your posts.
