It might be easier then you think... the Eclipse has one, their intake and exhaust ports are alot like ours, you might have to drill out the holes a bit wider. I havn't checked the intake, but I know the exhaust ports line up with a bit of modification to the stud holes.

Show me some proof to your theory.</div>

here for you
http://www.velocity-of-sound.com/velocity_...calculator2.htm

it will calculate for you the runner length with the spec of your cam , your choise of induction wave ( the first or second or third ) , the Desired Optimum RPM and your Diameter of Intake Runners

here you will find some explanation of induction wave and alot more fing02.gif

I've already got book marks full of calculators + files upon files on tuning intake manifolds and heads.

Thanks for the additional information anyhow smile.gif

 

No i was at the DB campus.

And if you want an idea of what mine will look like, cross a plenum intake with an itb setup and you kind of get the picture.
