350z intake manifold on 5.5gen, pics inside...
Finally got around to getting my welds done. i made it work with some modifications 
but i did it . no dyno as of yet but soon.... soon as i get some money. not sure if im the first but ill find out from the post below...

good job man! tune the sucka and dyno!
Which IMs did you get? regular or rev-up? (FYI to anyone that does not know, the two ARE different in the LIM and the lower clamshell AFAIK. Revup has shorter runners for better breathing up top)

Using the 350z LIM is not optional; it's a must. But even if the port spacing wasn't different (which it is), both the FWD and RWD LIM's are the same height so that wouldn't make any difference.
Using which LIM?
I'm gonna try this with my 3.0....I'm gonna try and use the revup lower and the kinetix top half.

i did have to modify the hood. took off the padding and cut out the support beams in the middle. i had to move the harness in the middle and take the bolts that hold the fuel rail to the firewall to flip the fuel dampener upside down so the throttle body would bolt up. once i got the upper plenum welded there was no turning back lol.
went to the track but wasn't satisfy with my times. but it is my fault. im too broke to afford a tune and new spark plugs before the deadline. but tax season is coming so that will be my last trip to the track N/A...

Did you have any issues rerouting/relocating the vacuum lines? Specifically, the EVAP canister solenoid line and the one line (can't remember) that used to go to the back of the elbow?

If I recall correctly, haven't the few people that have done this mod shown that without the 350Z cam timing maps, the 350Z IM is outperformed by the FWD IM (in particular with the SSIM mod)?

If you're referring to Meximax's dyno, he didn't have CVTC at all. The default cam timing that most 3.5 swaps run is good for mid-range power. This also happens to coincide with where the FWD VI is it's happiest. The OP's car actually has CVTC, so let's see what happens before drawing conclusions.

I was thinking he never thought the 350Z IM was all that great, but after some research I found he did see an improvement in his track times and grew to like the 350Z IM better.
He went from a 12.489 @ 109.34 with the 3.5 IM, to a 12.48 @ 111.09 with the 350Z IM. And then was able to do even better by adjusting the CVTC.
So theoretically there should be gains with the 350Z IM.

I installed a 350 intake on my 3.5 swap and on the dyno I went from 258 to 274Hp.Also gained a lot of torque but I can't remember the number of the top of my head. I had the kinetix intake on instead of the ssim though. I'll post my new dyno numbers later .One thing I did do with the 350 intake was I cut off where the 6 bolts in the middle of the intake were.I ground the inside of the top half of the intake smooth then welded up the holes.I did put the spacer on so I had to run around town like a redneck with my hood off and the intake pipe and filter sticking out.I did get into the 13's with this setup on street tires and a 250 lb. passenger with me the last time I was at the track.Only got to do 2 runs because it was so crowded so I did not get to test the new setup out any better. Car was very loud with this setup. Even with my exhaust cutout open you could hear the intake sucking air.

My graphs are on the dyno computer at the shop. Just need to load them to my computer and down load when i can remember.When I'm at the garage I'm turning wrenches from the time I get off work 6PM until way late in the morning so I don't think about posting my graphs unless I'm killing time surfing on the org.The 350 z intake made a huge difference from the kinetix.I wish I had a ssim manifold to install and compare 350 z manifold on the dyno.What surprised me is how much torque I gained. I expected to actually lose torque not gain it.Of course with dyno run files everyone thinks I'm talking out my butt so I'll have to make sure to get them up but this setup definitely flows a lot more air and worked very well with my cams and some tuning.My time slip is listed and I said I got into the 13 just but with an extra person,street tires spinning, and just figuring out the shift points on the car but that's for another section. i will say this that past 6600rpm I thought the 350 intake would pull like mad to red line but it had the same flat line to the 7200 rpm cutoff as the kinetix hence figuring out the shift points of the car and getting faster times at the track.I would love to see someone run boost with the 350 intake and I seriously thought about it but I've decided to move on to other projects and have started selling off parts of my car to other members on the org.
