Contour Enthusiasts Group Archives Forums Modifications 3.0L Duratec New intake manfolds

Im starting work on the 3.0L mani soon with David Z just letting everyone know. The core should be in next week. The plan is a twin throttle body seperated plenium system. These will be for sale to everyone in the near future.

With oval port to??? Please

Im working on it. Im opening the 420A neon/eclipse engine, the 4g63 turbo eclipse, zetec contour/focus/escourt,supra 2jz-te and the earlier model NT head as well as 3.0L oval port all in the next couple of weeks. If someone in the mazda 6 community has a stock, complete, intake manifold core i can take some money off the price for them and begin work on these as well.

Is this a one piece setup , or two an upper and lower. When is expected time of completion and price for oval port 3.0?

Looking at 500 with shipping for a one piece intake manifold for the 3.0L. About 2 weeks id say we should be rolling hard on these.

Anything like these completed designs?

You may want to contact David to see if he has any dyno or flow data available for you. Depends on if he wants to make them, or will let you carry the ball.

Youv come across another david evidently. I have faith in computation itll be interesting to see how his setup compares. My trumpets are much improved over his valve seat cut plate for flow. Using fully rolled back intake trumpets cut to wave tuned length depending on clearence and what not.


The disign will be close to that but david is handling the linkages. Save the show polish unless he requests.

These will fit under the hood right?
