Z1 headers + Motordyne Manifold

Megan370z

Not too surprise on the intake manifold.

they probably went a bit light on the production intake manifd porting since they made a piece for their shop car.....

If anybody search more deeply into this. They will discorver the first pictures of that intake manifold had a lot of porting done to it by the runner entry vs some production unit that some guys showed picture which had barely any porting sign as in comparison of their first one.

Dont get me wrong they are probably doing it by safety of not scrapping the unit by making a hole it it and having to do some repair after....

hey Black_, from first hand knowledge the trick to these motors is getting cool clean air in & out as quickly & efficiently as possible. There seems to be a wide variety of opinions on headers. It seems headers will sacrifice low end power and you will loose some off the line ummff for top end performance. That's why I went with stock manifolds and the HFC's to the Stillen exhaust. Across the board everyone seems to agree (rare for any forum) the stillen G3 is the best intake and will give you good hp gains for the $$ spent. As far as the exhaust I liked the sound of the Stillen and the fact they add some weight in the *** end made sense since many people say the car is a bit light in the rear.
I went for the Z1 intake kinda blind as this my first go round with a plastic intake. I'm way more familiar with aluminum that has an e on it. If you don't know what your doing and start hacking away on your intake you can wind up going backwards and decreasing the air flow and power output. Unless you have gobs of experience or a flow bench that can measure air flow you just guessing. I figured what the hell for the $$ it's way cheaper than a motodyne & better than taking a stab in the plasitc.
