I'm sorry. We don't currently have plans to conduct this type of testing. But without a doubt, the MEVI will benefit from the lower intake manifold temps.

 

is it possible to buy individual parts of the kit? also is the TB spacer thick enough for a nitrous nozzle?

I sure it will benefit from the lower temps but I just want to see if a mevi will see upper rpms gains and if there is enough gain in the midrange to makeup the loss from the usim to mevi convert

 

The 1/4" TB Spacer is not thick enough to tap for a nitrous nozzle. But if there is demand, I can design a kit that willl include a TB Spacer thick enough for a nitrous nozzle, lengthened TB bolts, and a TB cable relocation adapter plate. The spacer can be already tapped for your needs if you prefer. It just will be made of billet aluminum instead of the type of phenolic we use.

And I'm sorry, the 4th gen kit will only be sold as a complete kit just like the VQ35DE, VE30DE, and VG30E Kit.

 

Are there any updates on the release of the spacers?

 

Yes. The 4th gen Thermal Intake Spacer Kit is expected to be released this week.

The price has been set at $215 plus $10 shipping. I have also chosen to include a Titanium Nitride Coated Step Drill Bit for an extra $10. This will help when enlarging the bolt holes in the stock EGR tube.

We should have full pictures available on our website by this Thursday.

 

Great. The price seems reasonable. Again great work aaron!

 

Update: The VQ30DE 4th gen Maxima Thermal Intake Spacer Kit is now available for immediate shipment. The price has been set at $215 plus $10.00 with the option to purchase a Titanium Nitride Coated Six Step Drill Bit to easily enlarge the bolt holes on the stock EGR Tube.

Installation instructions have been added to the NWP Engineering website in PDF format.





Thank you for everyone's patience and support!

Nice. I have a question, I know temps may not be an issue on the 00vi but I noticed you also have the LIM gaskets. Would this be an option for the DE-k?

 

^^ yeah that's what I'm wondering...I wish I could get only the LIM spacers

 

i'm still curious if the whole setup would be beneficial to the VI. I know the heat isn't an issue but with the LIM gaskets, and the extra volume with the UIM spacer...wouldn't it still be beneficial?

 

If the LIM is exactly the same, yes, this is an option for the DEK engine. These Thermal Intake Spacers are perfectly port matched to the stock intake ports. So if the LIM is even slightly different, it will not match up.

Within the next couple months, it's possible we can sell the LIM spacers by themselves if there is a demand for it, especially if we decide not to make a full DEK kit.

We had this delima with the VQ35DE Maxima/Altima Kit. We thought about offering different stages of the kits. But honestly, the full kit is what was tested to show the HP increase. The full kit is what the customers got. We didn't want to offer a particular spacer by itself when we felt this would not provide any noticeable HP increase.

I assume you are referring to the VI from a 00-01 Maxima. You're right, heat really isn't a problem. I don't think heat soak is a problem either when racing. The LIM Spacers alone could help in theory. They did surprisingly decrease the temperatures of the LIM itself by 43 degrees! On the VQ35DE Maxima, they only decreased the LIM temps by 30 degrees. I was surprised that the VQ30DE engine intake temps are so high compared to other Nissan engines. Even with the thick rubber intake gasket, the UIM still gets MUCH hotter than any other engine we've tested. As soon as I did the preliminary testing, I knew the VQ30DE would benefit from the decreased intake manifold temps.

But the LIM Spacers are only 1/16" thick, so they don't shift the power band at all. If you also went with a 1/4" UIM Spacer, it could possibly help. It would probably shift the torque band slightly lower and would improve airflow slightly since you are eliminating the stock gaskets. But without a major decrease in intake manifold temperatures you could still possibly lose a little top end power. At this point, I don't know if we will conduct any testing on the 00vi. If someone would like to volunteer their time and would pay dyno costs, I would be willing to work out a deal with a prototype kit for the DEK.

 

hey i dunno wher the other post went, maybe it got deleted, but my question was do these spacers replace the both rear and front valve cover gaskets? Im gettin a oil leak and needa replace the valve cover gaskets, will buying these spacer replace having to do that, or would i still needa do that?

 

I don't think the kit has anything to do with the front valve cover.

 

Valve cover gaskets are completely separate from intake manifold gaskets (or spacers). But if you are going to replace your valve cover gasket, now is the perfect time to install these Thermal Intake Spacers!

Please let me know if you have any more questions.
