Intake Manifold for NA Applications

mokhan996

I've been searching for an Intake Manifold that would do well on a NA application. I see that most of these if not all aftermarket Manifolds are for FI purposes. Been reading about AAM and how horrible everyone's experience was at first when they launched 4 years ago. Was wondering if anyone has installed the AAM Intake Manifold on a NA setup and seen results on the dyno or in general. Was looking at the GTR conversion, expensive as balls but looking for power and it's obvious if I wanna make power I have no choice but to go FI. Kinda wanna see what power I can get out of my motor without boosting it. Any advice? Or is it FI or nothing :/

There isn't one. The stock manifold has proven itself over and over against a number of challengers.

Basically, the aftermarket manifolds are not worth the money for NA. The power gains are minimal (or negative). You'll need a lot more modifications to gain anything of note. But by the time you get there, you might as well have considered a basic SC or turbo kit.

modern injection moulding processes are very good at making intake manifolds. combined with the modeling software used by OEMs it's very difficult to improve on the design.

that's a good thing tho - nissan already included the best possible manifold, at no extra charge!

You could always order one of the motordyne manifolds or on of the z1 manifolds.

Yeah I figured haha. I'm looking into SC but honestly I dont see anything other than Stillen and I'm not sure how they are, since I haven't read or seen anyone with them besides one or two guys on Youtube. Sucks the NA class cant make decent power with bolt on mods and tune. I mean, maybe, but I'm looking at a range where it'd be cheaper to boost lol. 525-600whp range.

mokhan996

Yeah I was looking at those too, but how much more HP can you gain by porting a manifold?

Top gunz has an awesome SC Kit. Forget the Stillen. There’s an entire thread in the FI forum dedicated to his newest offering.

Just don’t get yours before I get mine!

More than be gained by switching to aam lol

I have no plans to go FI, so I decided on a Motordyne M370. Combined with my other mods, I like the power and responsiveness its added.

Granted, the two dynos were on different days, but the only parts difference was ported upper and lower manifolds and retune. Peak power and torque wasn't much but that mid-range gain the real deal.

Yeah I seen his thread. Didn't he swap out the Stillen manifold for the OEM one? Ayee you're gonna SC yours? Excited for you lol, I'm in a huge debate going back and forth if I should remain NA with a ton of bolt ons or SC.. decisions, decisions lol. I personally never wanted my car to be FI but lately I've been really into FI and wondering what it can be lol

mokhan996

That's what I've been hearing lol.

mokhan996

Yeah I was siding with AAM until I've read all the bs many people have gone through and the loss of power. If I don't go FI which I never had plans to either, it'd def be Motordyne or Z1 Ported Manifold. Did you tune/dyno yours to see how much whp you're making?

mokhan996

Nice!! That's not shabby for bolt ons honestly. Did you use TB spacers for your EPS TB's? And plenum spacers?
