Installing Ported Upper & Lower Intake Manifolds on The Z

Рет қаралды 120,885

To make more power while staying NA, the flow of air going to and from the engine needs to be optimized. Most auto manufacturers produce cars to work well, however they are okay with having an adequate final inspection. That somewhat poor quality control means there are many aspects of the car that can be improved on without reinventing the wheel. In a previous video, I removed the imperfections and casting marks from the upper and lower intake manifolds on my 370Z (kzfaq.info/get/bejne/oM5yZ8mFzbGzhXk.html). In this video, I’ll be going through the complete installation with torque specs. You can find the products that were featured in this video below by clicking on the sponsored links below.

Arm chair analysis: smooth ports promote flow therefore air velocity...rough ports promote turbulence... turbulence is good for fuel mixture. So it's a matter of determining what engine likes what more...in this case we got fuel injectors so I think the whole mixing might not be as important

You are better off getting a 3" intake and bigger throttle body's on the plastic intake models. The Japanese are very smart and knew what they were doing when that designed the smaller ports due to Bernoulli's principle. Also a quality exhaust is a huge plus on Z's and the G's

Awesome video the upper intake and lower intake ported nice the one thing to help it breath better upgrade the throttle to bigger size and port the heads and port the exhaust as well and upgrade the intake valves to go with the ported heads on the cold side and hot side It's sounds crazy and money to do all of that u will see more power and worth it depends on the individual but I would

I hope you measured the head ports. While this may help slightly and I mean slightly .... no point in more air coming in if the actual head ports are smaller and basically creates a bottle neck effect.

Love the video and the project. Props to all of us DIY guys. Question though: doing it manually at home by hand... my concern is that you'd end up with slightly different sized ports just due to human error and "eye-balling it". I wonder if there is any way to measure each port to make sure they're as close to identical as possible?

This is a good mod on the vq35de as well. If you take the time and do it right. Research it. You can find a lot of info and pics of ways people have tried if you are willing to google a lot. Also something else to look at is the performance shops and their ported parts to base your port job on.

Interesting video, however most tuning specialists I've heard of usually re-profile the intake and exhaust camshaft to accompany gas flowing (porting) the intake manifolds. Otherwise even after a "tune" the gains are minimal.

@v36vhr Жыл бұрын

I didn't make any power with upper and lower ported manifolds, dyno proven unfortunately. I went with a knock off company lol. Even with a tune it made no power. Maybe it depends on who does the porting and if it's done right? The upper and lower manifold should be port matched with one another. NoTrigga and z1 are the best on the market.
