First SSIM in a 6th gen
So I had time and urge to do the install today. I even skipped school to do it! 
The IM is held on by 3 bolts in front and 2 nuts on the sides...it's the f$#@ hoses/clamps, and harnesses behind the f$#@ thing that were a royal PITA!
Briefly put...behind the left side there are 2 hoses that need to be disconnected, 2 harnesses that need to be unclipped, and one 10mm or 12mm nut that needs to be taken off.
Right side=behind it there is a coolant line that you have to disconnect which is very tight! Then there are two more hoses in front of the TB and the TB harness to disconnect...and one more harness.
If someone does NOT already have the IM spacers from Aaron, then
on getting the elbow mounts off...two top bolts are easy, but bottom right is WOW tight.
Install went fairly well except for the coolant line, but it all ended up fine...I hope it stays that way. All bolts/nuts were put back on and clamps were tightened except for one and it's the one behind the left side of the IM and it's for blow-by...and it's on pretty tight, so I'll just check up on it once in a while...couldn't get pliers in there to tighten the thing.
I started the thing up and the idle was fine, but there was a SES light...car ran perfectly fine though...
Granite that it was a little wet out on the roads, the thing still broke loose like no other...and I have not felt such torque steer since the first day I had my car! Low-end had no noticeable loss for me...maybe it's because I also changed my plugs?
50mph 2nd gear=
80mph 3rd gear=
The thing kept pulling strong up top and I didn't even use my 7,100 redline

Look at the post above yours^^^
It guts the entire shelf out of the stock IM and smooths everything out...one can either do it them self, or pay someone to do it. I do not have the tools to do it and didn't want to spend the money on the tools needed, so I just paid someone to do it
You can use your IM, or buy a spare IM...service=roughly $100 just for gutting the thing out...this thing is the sleeper version and the proven version of the Kinetix IM

I tried doing the pedal reset for the idle...but my timing sucked and I had no patience for it, so I went to my Nissan tech and he did it with his computer within a minute free of charge

I want my b-pipe and then I should be on my way, since the headers aren't coming out any time soon.
Without headers I am hoping for 240-250whp...
I did not do the cutting myself because I did not want to buy the dremel just for this one job...KRRZ350 did it from the forums...

We will see once I get it done...either way...I am happy with what my motor puts out...it's just that I hate my suspension and steering, which both need gobs of grease slobbed onto them everywhere to stfu!
EDIT-I just looked at my old dyno sheet and I made 220whp/240wtq with only Fujita and TS ECU...so I would easily assume that SSIM, IMS, y-pipe/b-pipe and other miscellaneous performance mods would put me right around my target range...I know, I know...NO DYNO NO CARE, but those are my educated guesses

Agreed, what does SSIM stand for? 
and what does it do?
Is it the same thing as NWP intake manifold spacers just a different brand? If so then I understand, but are the differences in your opinion.
Not sure what this is either.

Plus prjctmax also has TS Re-flash, SSIM and new plugs.
He's good for at least 240 if I get 236.

What were the SAE values?

What have you done to your autotragic 4 speed to get 242? nnnnn what are SAE values? Sorry I dont have 20,000 posts worth of knowledge to know what SAE means. Unless it referrs to "Society of Automotive Engineers" values. But what values?

It is, Society of Automotive Engineer CF (CF = conversion factor) BTW: Post count doesn't mean knowledge.

you know I have been wanting to do this along with the TBS but I can't seem to figure a safe way to purge and remove the fuel line. Doesn't really give a step by step in the service manual. Please post a how to sticky on this one. thanx. Looks good and don't let anyone discourage you from achieving your goals. Ohh one thing I was wondering is why you didn't go inside further to remove more. I think this mod is awesome and creates somewhat of a venturi effect. Only thing I would think that would make this even better is a dual intake like the 350z.

The spacers are exactly that, spacers, whereas the SSIM is an entirely different mod
The picture is the IM with the SSIM done to it
What?

I will post a picture tomorrow with all the things needed to be removed circled in red.
I did not do the cutting myself, and the person that did was saying that he does this work better than anyone else...so ummm

I know you can also polish out the IM by using real fine sandpaper, a sponge and power drill. A bunch of guys on an altima site did it, said they had some gains and a couple of them posted some dynos I think. Over on Nissan club

I think you just lost low-end torque and mpg. The plenum is set that way to provide lots of torque and improve volumetric efficienty at the low end. Higher torque = better mpg in that rpm range.
Were you planning to port or polish the runners? Got 10-15% better air flow @6000 after I ported/polished mine.

How did you measure the 10-15% better flow?
The runners were supposed to be polished up quite nicely by the guy that did it, but ummm...as you can see, he didn't!
Either way, I know that there was a noticeable power gain, so me happy

MAF reading? Every one must / should also realize that !PrjctMax! should have Z33 CVTC maps & DOES have a 7100 rev limit.
If he's porting, then he's making things significantly larger to where he need to port match.
If he's polishing, he's taking off very little material, but smoothing it out, which shouldn't require much port matching if any at all.

Went out for a drive and here's some more feedback:
-I can definitely feel roughness in air flow around 3,500-high 4,000's...most likely due to the lack of smoothing the runners out?
-Low end has a noticeable lag to some extent...nothing horrible, but noticeable
-A few runs from 3rd gear from about 60mph at 3,500-6,500...lags a little and then picks up around 4,500...few times it felt like VTEC mode y0
-Gas mileage seems to be about the same if not slightly better...I know the carputer isn't accurate, but the miles that I have driven compared with the miles I have left are slightly more than before...and I've been womping on it quite a few times.
Overall I am happy with the mod so far considering it didn't cost an arm and a leg like the Kinetix, but I know that there is room for some improvement if I were to smooth everything out in the IM.
I'm sure that the ECU still has some adapting to do since I only put <100 miles on it.

I just dropped off my intake at a local machine shop to have the shelf removed.
Since I'm in a manual I hope I dont loose much bottom end tourqe because If i do someone will be getting a whicked trade for their stock UIM.
Plus 350z doesn't use VIAS and those things are quite peppy.

Completely different setup here. Not to mention the Z33's CVTC maps, ECU programming, etc. Just because the Z doesn't have a VIAS in the IM and is still 'peppy' doesn't mean anything in relation to yours.
A33B/A34 SSIM'd UIM ≠ Z33 plenum.

While the correlation between the SSIM mod and increased horsepower may be in doubt, I think I've found another correlation which can be backed up by objective evidence:

Care ≠ not me.
Because, once the SSIM is in I'll dyno the car and send the ECU to technosqare for a proper tune.
All im saying is I hope i dont loose a lot of low end TQ.
