I just got back from Aarons couple of minutes ago.
Temps went WAYYYYY down, but i'll let him post the full results.
Took over 7 hours of testing/install to get it finished.
Fitment is UNMATCHED. Seriously, these things look almost like Nissan made them for the car.

First Impressions:
I can definitely feel the difference. Low end torque is increased, and my 0-60 speed feels better... Can't wait to see the actual results from the Dyno tests that were taken.

The only issues at this point is that I have to go through that whole process for the pedal on/off setting or whatever.
That, and the idle is a little high... so we're going to try to figure out the culprit...
Most likely I just need to let the ECU relearn everything and what not.

You don't know the results off the top of your head?

 

^^ ya what he said , you dynoed but don't know the #'s?


Hurry aaron and let me know how much to send and were to send to.

 

yeah man, i wanna see a friggin dyno.... im expecting 10hp 10 tq throughout the band baby!!! btw, soonerfan, you have a33 emblem?? that looks awesome.

 

im in for them if they give 10hp!

 

It wasn't a dyno jet.
He's having to enter in all the info for my car.. weight, gear ratio, clean up the actual runs themselves, etc etc...
It'll be up in a day or so.

 

Sweet can't wait to see.

 

You must not know the equation for HP ...

This type dyno was used.

My money is on a vac line not reconnected properly. I also doubt you need to reset the fuel trims, although it can't hurt to do it.

 

OMG Low-End heaven for me!!! In for a batch now.

Puppetmaster - Do you know how to install these? In for a meet.

 

its should be pretty easy

 

is this thing easy to install? how much will it be?
will the seller ship to Canada?

 

read the whole thread

read the whole thread

 

Yeah, I haven't done either of these yet:
"Throttle Valve Closed Position" procedure must be done every time the TB is unplugged, along with the Throttle Released procedure so it knows WHEN you have released the pedal."
I'm going to change the oil, re-check all torque settings/vacuum lines, and do those two procedures tomorrow morning.
The manifold was nice and cooooool after some city traffic on my way home from work.

 

I just wanted to let you guys know I am not ignoring you. I am still compiling all the data before I release official results.

Plus, me and Blackmaxx96 are working on a minor issue. I am pretty sure his ECU has to relearn a few things since we disconnected the battery terminal during the install process. Also, we need to make sure the ECU learns the Idle Air Volume by doing that learning procedure.

But let me just say this, so far, the power gains are about what I expected. Which is a good thing!

Also, the upper intake manifold temps dropped by over 40 degrees on average! The lower intake manifold, elbow, and TB temps all dropped by over 30 degrees on average, which is amazing! I'm really happy the lower intake manifold temps saw a decrease that large out of 1/16" thick spacers. The rest of the kit has 1/4" thick spacers.

maxximaa, before I release a price, I need to finish all the testing. But the install process isn't too bad. The estimated labor time is 2-3 hours. It's much easier than doing it on the 3rd gen Maxima. And yes, I ship anywhere in the world!

 

I dont know about that minor isuse. Sounds like it has something to do with has vacum or something, dont see how the spacers would mess with idel and etc. Could be something else not related to it.

Good luck and keep us updated

 

I know you just finished these, but any word on a set for 6th gens with the EGR.

 

I agree. There is just no way it could be due to the spacers as long as there are no vacuum leaks. I won't release the product until everything is perfect.

Yeah, there is a thread about the 6th gen spacers in the 6th gen forum. Feel free to post any questions there. I plan to solve the EGR problem on the 6th gen just as soon as these 5.5 gen spacers are ready.

 

Take it to the top! I'm still very interested!

 

Aaron,
im hoping i can get these before moving away from the area in about a month...any chance?
Jason

 

UPDATE:
The car runs perfectly..... exxxcept for the the fact that my #1 coil pack is going to poo, and my idle is slowly getting worse and worse... not to mention the car is slowly losing power
I just needed to do all that stupid ECU stuff to fix all the throttle/idle issues.

Trust me, you guys will be amazed once you see these things in person. Aaron was so absolutely meticulous about design... They look like something Nissan would've made!

 

I'm just curious, but to remove the lower intake manifold, did that require the removal of the fuel rail?

 

This sounds promising.

did you guys get to do any dyno runs?

 

no, the intake manifold connects between the cylinders and the fuel rails or underneath connected to the cylinder heads.

this is the IM removed...you can see the fuel rails

 

damm, It looks like you DO have to remove the rails to take off the lower manifold...........

Any one know for sure?

 

You do NOT have to remove the fuel rails, injectors or anything.
You take off the LIM all in one unit with everything bolted on.
When aaron posts the pictures we took you'll see.

Mike

 

hm any idea if this will work on the 02-06 Altimas? i know the 05-06 have the EGR tube/valve...

 

From what I remeber it looks exactly the same to me.

Should work.

 

This should work great on the 3.5L Altima w/o EGR. After this kit is ready for sale, I will make a kit for the 6th gen (04+) Maxima which does have an EGR tube. The newer Altimas should be the same. If they aren't, I will design a kit for the newer Altimas if there is demand.

We did do dyno testing. Since this was done with Home Dyno, I still have some cleaning up to do on the run files. I hope to release dyno numbers in the next few days. I don't want to release ANY numbers until I have everything compiled and have full testing results.

Yes! There is a very good chance these will be ready for sale before the end of April.

And just to let everyone know. Blackmaxx96 is right. You do NOT need to remove the fuel rails! This makes the install process MUCH easier! Leave the fuel rails connected and raise the lower IM upward with everything attached. There should be plenty of slack in the fuel hose to have room to set the lower IM aside while you clean up the ports and install the spacers.

 

Gotta love return less setups!!!

 

Subscribing....

 

anxiously awaiting dyno charts...!!

 

Something in the works for other models?

 

Yes, see what I said 4 posts above yours.

 

Every time you post i get excited. ^

 

Ill take one asap !!!!....just polish my spare upper and lower IM ....waiting for this to do the install !!!

PM sent !!!

 

yes...anxiously awaiting a paypal address....

 

Just as soon as they are ready for sale, I will add this item to my website. There, you can purchase the spacers via Paypal.

 

Can we at least get some teaser pics

 

or do you mean on a VQ35?
