no disrespect but I came acroos these gaskets on ebay http://cgi.ebay.com/ebaymotors/02-04...9816QQtcZphoto

how much better quality is yours compared to these. Is it just the thickness?

Those look more like head gaskets, not IM gaskets.

*knight_yyz* · 03-06-2007, 09:50 AM

those gaskets go under the lower IM, you will also want the ones which go between the upper and lower IM. www. Nipponpower.com may still sell them, They did a few months ago any way.

NisMax03 met me this past week in order for me to design the kit for the 3.5L. He has a set of these installed on his car right now.

They are made of 1/16" thick soft plastic (I believe Nylon 6) which is not rated for more than 230 degrees. My material is rated close to 300 degrees and is MUCH MUCH MUCH harder!

These spacers on the eBay auction are meant to be installed below the lower IM. They can't be any thicker than the stock gaskets b/c of the slant of the intake ports on the heads. It won't match up if it's a 1/4" thick.

Also, according to NisMax03, the gaskets were poorly matched to the intake ports on the heads. Most likely, they were just a scanned copy of the stock gasket. He said they didn't line up correctly to the ports and overhung the edge of the port, obstructing the airflow.

My spacers will be a perfect replica of the actual design of the intake manifold itself. I don't copy gaskets. Stock OEM intake gaskets are never port matched. My spacers are designed to line up with your intake ports perfectly for optimal airflow.

The VQ35DE Spacer kit should consist of two 1/16" thick lower IM spacers, a 1/4" upper IM spacer, 1/4" elbow spacer, and a 1/4" throttle body spacer.

Epacy, about the FSTB. That is something I noticed with NisMax03's car. He has a FSTB and it's already touching the top of his elbow collector where it meets the upper IM. He had to add some washers to raise the bar up.

So the only way to make it fit still would be to raise the bar up 1/4" somehow. I've determined with NisMax03's FSTB, it will still clear the hood if it's raised a 1/4". The only problem now is not being able to lengthen the strut studs that the bar mounts to. So maybe new ET style nuts will be needed along with the FSTB spacer for the nuts to be able to thread on. In the future, if there is demand for it, I can add this as an optional kit.

What do you guys think? Anybody got some other ideas to solve the FSTB issue?

*Derrick2k2SE* · 03-06-2007, 09:22 PM

I'v got a good inch or so between my bar and the elbow. I do have the ES motor mounts that lower the motor a bit though. There seems to be some room to grind the elbow down some to make it clear. It's not like it's a stressed part.

I'd just make it clear that it may interfere with some strut tower bars and let us figure it out as we go. We could grind a little and shim the STB with some washers to make it work. That's part of moding any way. Offering an optional kit to raise the bar seems like a good idea too.

*knight_yyz* · 03-06-2007, 09:30 PM

I don't think raising the FSTB with washers is a great idea. Unless you want to screw up the threads on the bolts there. You should put nuts underneath then washers then use nuts on top again... IMHO

That's why ET style nuts would be needed. But they may be a little difficult to find. It's just an idea I'm throwing out.

Step one is to get these spacers developed!

Derrick, I looked closely at the elbow and I don't see how you can grind down more than an 1/8" of material without damaging the threads used to hold the elbow to the Upper IM. Regardless, grinding should be a last resort. Most people want to make their engine bay look pretty.

Sounds good. I'm definitely interested. I'll keep my eye to see when you start selling them or pm me.

*Epacy* · 03-07-2007, 07:07 PM

Also, just grinding down, however far you can, while the car is sitting there turned off isn't going to exactly solve your problem, as the engine will move/shift during operation.
The idea about spacing up the FSTB has been mentioned before. I could see it working, don't know if there would be possible negative side-effects.
Not sure if aftermarket struts have longer studs than OEM. What kind of struts were you working with Aaron92SE?

*maxspeed96CT* · 03-07-2007, 08:11 PM

Since these should be done soon, whats the estimated price ?

The struts that NisMax03 has are the adjustable Illimunas.

I still have not completed the design of these spacers. So at this time, I have not gotten CNC price quotes. The pricing will be solely dependant on the CNC pricing since they are 90% of the costs.

I have the parts I need on their way as we speak. As soon as I get the manifolds from another org member, I will develop the CAD drawings. Once that is complete, it shouldn't be more than 10-14 days to get the first run in my posession for testing. Then my very eager test vehicle volunteer will drive to my shop and we will do all the testing and dyno runs in one long day. Then within a day or two, the product should be available for sale if everything goes smoothly.

I hope you guys can hang on a little longer. I am working all day, every single day to get these made!

***blackmaxx96*** · 03-07-2007, 09:55 PM

Oh yes i'm eager

2002AltimateV6 · 03-07-2007, 10:22 PM

VERY excited to get this up and going. Curious to see how these will work with nitrous.

Should be fun!

Waiting, but hopeful! Thanks for the effort you are putting forth for the community, it doesn't go unnoticed.

Update: Who has an OEM lower IM gasket laying around that they can accurately measure the thickness of?

A vernier caliper will probably be needed to satisfy my perfectionist quality. If I can get this measurement, it will speed things up a bit since I won't have to order one from the dealership. Thank you!

*knight_yyz* · 03-10-2007, 03:14 AM

3.00 mm or .118" measured with a micrometer because I'm a toolmaker who is pickier than you

Aaron, I found my old lower IM gaskets. I can send them to you if you still need them. Let me know.

If that is the case, then an 1/8" spacer could be used for this. 3mm seems VERY thick for this type of gasket, though. Were these the original OEM Nissan gasket? Or were they an aftermarket gasket from the parts store? Is it solid metal or is it metal with rubber inserts around each port like the upper IM gasket has?

NisMax03 is sending me his original OEM gaskets just so I can get my hands on a set in order to base my designs off of.

Thank you for the measurement!

*knight_yyz* · 03-10-2007, 03:05 PM

Sorry I forgot to mention, the gasket I have is nextgear lower IM gasket. I figured if theirs fit no problem then 3mm is a good starting point. I don't see a problem with going 1/8"

*maxspeed96CT* · 03-10-2007, 06:19 PM

keep us posted on everything youdo, im waiting around like a hawk
