Z1 ported intake, worth it??

Gelato_Z

Is it worth getting upt intake manifolds on a completely stock car?

Spooler

I would say no, get an exhaust first. If you are worried about your noise level, get a factory Nismo exhaust that someone has replaced.

Quicksilvers

I would say no it’s not worth it. To gain 8-14 whp for all the labor and coin spent to install the Z1 ported intake manifold is not really worth it from what I have seen. I agree with Spooler start with your exhaust first.

JLarson

It's actually pretty cheap/easy to install this part, personally I thought it was worth it - especially if you can get it on sale. Edit: Only applies to the Z1 mani, didn't think the M370 was worth the cost.

Can we stop derailing this thread? I have ported upper and lower and gained power through the whole power band.

Isn't it necessary to piece the intake manifold with the lower portion too, to see any real gains? I thought there is a second, lower manifold component available from Z1 to pair with their manifold. Sold separately, but really, should be together from what I gather.

Yeah, this thing:

They even say the following right in the ad:

I did the full Z1 kit, ported upper and lower, headers (which I ceramic coated), cat delete and the cold air intake. Had an ecuteck tune done by Jtran. Ended up with 326 hp at the wheels with stock NISMO exhaust Dyno chart attached.

Talk to ZGirl, she recently got the Z1 400hp kit installed on her Nismo and she can have some real life recent opinions of the install and performance gains.

I want mine on the top side (5-5500 & up)

Then you need to stay OEM.

The following link pretty well explains the advantages of the M370 (350HR) intake manifold.

Review: Motordyne M370 Manifold w/ Comparisons

I made a DIY 350HR and can definitely feel the extra area under the power curve when using the stock 7AT 7300rpm shift point. If you are revving higher to shift, the low rpm gains are less useful.

if you want top end power stay with OEM..the VQ35HR(m370) is great for mid-range if thats where you want it..seriously though if you can cut plastic with dremel you can save yourself a ton of money on the M370 and do it yourself.
everyone of my dynos i made more power on the top end with the stock plenum..

my buddy hand ports them. Friend of mine two different dyno made 360whp with PPe cbe and his manifold. I picked up 14whp in parts of the powerband untuned.
