Hey guys just giving an update. I've got most of the generic materials, and the runners are being custom made by a shop down in Nascar land with a mandrel bender. I should have some real progress in the next week or so, depending on the mandrel shop and on my own.

There were alot of issues with the kinitix that were kind of lost in the translation. There were basically alot of design cues that could have been taken built upon and made huge power. THey jumped into it without going past sticking a stock sized box on a set of runners and that was it.
1- Key differences will be that this will have internal velocity stacks on each individual runner to assist in airflow within the manifold.
2-Plenum volume will be approximately double the size allowing for more air into the motor, which in turn allows for more fuel to be added, which in turn with the proper tuning equipment will allow for alot of headway to be made in NA/Boost/Nitrous applications. As long as you can increase the volume of air evenly across all 6 cylinders, and tune for that increased volume your going to be in alot better position.
3-Allows the addition of a larger throttle body- 75mm is what im going with currently, upon adding cams, may look at going up to the 90mm, but for daily driveability, ive run a larger plenum manifold and tb in the past on an old chrysler 2.4 and it was a monster addition. WHen i added my crane race cams, it was exemplified.
4-Runner length can be customized to extend your powerband to 8k by or keep you in the neighborhood of lets say 7200 or just stock. This build allows you to target whatever range you want.
5-Custom options for nitrous plumbing afford you alot of options
6-Lastly it Reworks the archaic elbow design that plagues every ssim, and flows more off the top. Mine is going from a 3.5 inch intergrated intake/maf tube to the 75mm tb with the 3.5 elbow to keep flow up going into the cylinders
Im sure there are some basics i may have missed but these are the reasons I wouldnt touch the kinetix.
Do i expect that I will see gains of 50whp at peak? No. Im pretty sure i wont as i have a pretty good ssim setup. But I full well expect that this will be the last hump to get me to my goal of 280hp~ auto prior to going with cams this spring/summer.
A big restriction is in the intake path to the heads. Its been shown with many setups.

Thank you, doug! Nail on the head.
Only other major problem with the Kinetix is that the LIM ports are so mismatched as to be a complete joke. The Kinetix runners are 100% round, while our LIM has oval ports.
edit: to you guys hoping for an update, I still don't have any pictures yet. I've started making the Flanges which will be the most time consuming part of this project while helping the guy letting me use his shop to get his last project out the door. He's going to be out of town half of next week, so progress will be a bit slow.

Thermal dispersant, thermal barrier... Lots of choices. The prices would not be mine, since I would just be handing it over to a coating shop to do it just like you would. I'll try to call a few shops around here and get a quote.

Sorry for this going slower than intended guys. The guy who I am working with to build these is behind on a big project that needs to be moved out to start working on these IMs in earnest, so I am working 6 days a week helping him out.

Sparks, Have you ever read this thread? http://my350z.com/forum/intake-exhau...-de-motor.html
Out of curiosity what do you think made this intake fail? The sharp 90 bend in the elbow?
Also, have you gotten my Gmail Emails? I am definitely going to go with the enlarged elbow to 90mm, to ls2 flange, to adapter, to stock tb flange.

When it comes to that IM, there are just too many variables to try and figure out what issue there is, if any. The guy who said it didn't make power didn't post any evidence either.

Sorry to keep everybody waiting so long, this job is quite a nightmare but once it's done the shop is 100% free to get these IMs pumped out.
Keep on it sparks, and for anyone concerned about the EGR, toss it. Being staic, its quite easy to trick the sensor with a resistor to prevent the dreaded CEL. Also if anyone is interested, lmk if you want your IM powder coated...UNLESS sparks will offer this. Oh and for the record, C9's are about the limit. You surely dont want to try to run them on anything less than a piggyback, standalone is better, but I couldnt be happier. I did have to modify the under sides of the valve covers for added lobe clearance, but hey sacrifices.

Fountain installation is done. Dominic (shop owner) is finishing up the electronics and typing up loose ends at the Hotel so we can get started on the IMs when he's back in town.
Relying on someone else to get work like this done is a real drag... thanks for being patient guys.
