Nothing for us VQ30 folks?

 

unfortunately we're not as popular as the vq35 folk.
its a nice lookin spacer kit tho.

 

There was a spacer interest thread posted in the 4th gen forum, but it fizzled out. But regardless, I do plan on helping you guys out and conduct some testing to determine if a spacer will help the VQ30DE.

 

although the gains might not be as much for us (vq30de-k) will the spacers fit????

 

If the ports are the same, then it might fit. You could still see some gains even though you have a plastic IM.

 

anyone know if the ports are the same????

 

I don't think they are identical, but I think they are close enough to make it work. I'm not exactly sure what must be done in order to swap in the 00vi into the VQ30DE 4th gen motor.

 

hey aaron, long time no talk too has NC been? well anyways not to thread hijack i am also interested in the spacers for a 5th gen de-k, so would a few other people down here.

 

There does seem to be a little bit of demand for the DEK. I will have to do some testing before I make these spacers. Your intake manifold is made of a plastic composite and is not effected as much by extreme intake manifold temps. But it's possible you could still benefit from the other properties of my spacers besides the fact that they insulate so well.

They are port matched and NOT gasket matched. All gaskets have ports that are oversized. When companies make spacers that are gasket matched, that is a bad thing and it hurts airflow even worse than stock. But the Nissan Works spacers are port matched, which means a better transition from one manifold to another.

Also, you won't have to change intake gaskets again since it eliminates the need for OEM gaskets. The spacers should last you a lifetime since they are made of a VERY durable phenolic laminate that can withstand up to 300 degrees easily.

So, once I conduct some dyno testing on the 00 and 01 Maxima, I will be able to determine if spacing the runners on the IM would be beneficial.

 

please let us know if it will fit the 4th gen or not, there are a lot of us out here that need this mod

 

This particular kit is for the VQ35DE. It will not fit the 4th gen Maxima with the VQ30DE motor.

But don't worry, the 4th gen kit is currently in the works!

 

Not to sound like a di$$ but isnt $215 plus shipping regular price? I thought it was a group buy special. I just bought a couple of things and want this to be my next mod but wont rush if its regular price. I liked what I read about this product and have actaully link your product to other sites.

 

Thank you for your support. I strive to offer the absolute best customer service and product quality! I always appreciate it when my customers post links and reviews.

I'm sorry, but the price is $225 plus $10 shipping. This is not a group deal. I just posted this thread as a sponsor.

Please let me know if you have any more questions. I'm more than happy to help.

 

Thanks, will have to next month and will be my next mod!

 

I was thinking about purchasing this product for my 03 Max but I am having doubts. I was looking over the instructions and it seems they might be a little over my head. I asked around in the Northeast section, if there were any installers in my area that could do this install but got no response.

Aaron, do you think if I can’t find a car enthusiast shop, that a regular shop would install these. Also, about how much would they charge in your opinion?

Thanks for the info,
Jesse

 

Any reports on how this fits 4.5gens in terms of hood clearance?

 

Yes, a normal shop should be able to install these no problem. All you have to do is tell them that you have special intake gaskets that need to be installed. The estimated labor time is 2 to 3 hours. If they try to charge you for more than 3 hours, then they either don't know what they are doing or are trying to overcharge you. It takes many mechanics under 2 hours to do this job if it's their first time. Just make absolutely sure that they read over the instructions. Tell them that RTV has to be applied to both sides of every spacer. And also make sure they know that the bracket on the backside of the Elbow has to be removed from the vehicle entirely or the manifold will not bolt back into place.

I have sold the spacer kit to a couple VQ35 4th gens. I believe one has already installed it. As far as hood clearance is concerned, if you want to be sure, then you can measure it. The spacers raise the UIM by exactly 3/16" since you are installing a 1/4" UIM spacer and removing a 1/16" metal gasket. Also, the Elbow will now be 1/4" closer to the firewall. That may effect clearance if you have a FSTB.

But even on the 6th gens, where the clearance is VERY tight, there are no major problems even if you have a FSTB.

 

just making sure i thought i had read it in the cattman sale but these will fit with the kinetix IM?

 

Yes, they will fit with the Kinetix IM. The only part you won't be able to use is the Elbow Spacer since the Kinetix IM eliminates the need for one.

A few people on this forum have already installed these spacers along with the Kinetix IM with good results.

Let me know if you have any more questions.

 

Thanks Aaron for the speedy shipping of the kit. I will try to install it sometime this week or next. Will try to post some thoughts after the installation.

 

Your welcome. I'm looking forward to your thoughts. Hope the install goes smoothly!

 

any fitment issues on an 3.5 altima?

 

Nope, not at all. These spacers have been installed on several 3.5 Altimas, including the SE-Rs. They will fit without any problems on the 02-06 Altima 3.5L.

 

any update on the de-k's?

 

No, sorry. I'm still working on the 4th gen spacer kit. Once I get that out of the way, I can look into the DEK. If I can get my hands on a 5th gen 3L, I'll do some initial testing in the meantime. It could very well benefit from lengthened intake runners. I'll just have to make a prototype and do some dyno runs to see if there is a gain to be had with the variable intake.

 

NissanWorks has changed it's name to NWP Engineering. Same management, same great products, and definitely the same great service!

If anybody has any concerns or product questions, please do not hesitate to contact me.

 

Did this maxima have anything else done to it besides the spacers??

 

Well I finally got the kit installed by Kev at Goodwin Motorsports. He did a very good job. I got it done last Sun. and just rode around these past few days trying to decide how well this modification did.

From the butt dyno, I definitely can tell a difference when getting on the highway and also doing 4th gear pulls on the highway. It seems there is more power all thru the power band. It feels nice!

Also after driving around, the manifold cover is a lot cooler then normal, usually I would get burned if I touched it but not now. Wow, I seriously recommend this product to anyone that can get it. Quality product with quality service from Aaron!

Now I can finally get the VAFC II tuned…

 

Nope, there were 3 dynos done before and 3 dynos done after the installation of the spacers. The dyno sessions were done on the same day, same weather, and same exact conditions, except for the addition of the spacers.

The car already had an intake and catback exhaust prior to any testing. I'm not sure what you meant by your question. But that should answer it either way.

Let me know if you have any more questions. I'm more than happy to answer them.

Awesome! It is amazing how well these spacers insulate the intake manifold! Thank you for posting that review!

 

Had them installed by a fellow .orger last week.

I didn't post before so that I could get a feel of the car's performance.

There definately is a peak in power through out the RPM range and accelerates smoothly. Made my exhaust note a bit deeper.

One thing I really wanted to input was that I had a NASTY rattle at around 2500 rpms from my Y-pipe + exhaust. Now it's basically GONE! I can cruise at around 2300 rpms and usually you'd hear it rattling around slightly and now nothing at all!

Big plus. I don't know why, but the spacers helped!

Another thing is that. Yes...if you have a Stillen FSTB for 2k2 or 2k3 you will either need washers or grind off the top of the manifold that is hitting the bar. That's what it says in the Stillen instructions in the first place, but I didn't need it until now. The manifold hits the FSTB while in reverse. Will need to fix that while I'm off this week.

One question is that when accelerating you hear something sucking in air. Before it would only do it after installing the Injen at around 3k or 4k rpms. Now it always does it while accelerating no matter what rpm you're at. Is this normal or are one of my hoses loose?

Haven't done the touch method yet, but haven't noticed much of a change inside reading the temp gauge. Will try that when it's not so rainy out.


Thanks for a GREAT transaction Aaron


Will post back on anything else!

 

The spacers will definitely change your intake tone. In many cases, a whistling noise can be heard at certain rpms. I think you are fine.

Also, the stock coolant temp gauge in your car will not show any change by installing these spacers. Phenolic Intake Spacers do not change coolant termperature. They only change the temperature of the intake manifold and intake tubing.

 

Anything on the fourth gen, I need to change the rear valve cover gasket, and this would be a great time to install the spacer!

 

I'm sorry, we do not currently have the 4th gen spacer kit ready for sale. It is in the works as we speak. We hope to have it available within the next couple months.

 

Couple of months! You need to get the team of DE's on that!!! Which is probably you and a couple of friends doing all this, Well, keep us updated! and thanks for the reply, you have a website? any other products?

 

Actually, it's just me. I do all the design and developing myself from scratch. So if you ever need technical assistance, you talk to the guy who started it all.

I don't have any products for the 4th gen. But other than the spacers, I have several other ideas for the 4th gen that will help improve track times.

Cool, I'll check out the site, if you have them on there?

One man band huh, Well maybe someday then,

 

Bump... Plenty of kits left in stock! Ready for immediate shipping!

If you have any questions, feel free to post. Thanks.

 

think of it as a GD w/ no limit or no wait to order.
