If you need step by step instructions, you are not capable of pulling off the project. Porting is very straightforward, just time consuming.

 

Yes but you must know when to stop. The 6 port housings have less cast then the 4port but im on a 6port porting project with my meckanic. Pics dont work here. Emial me and Ill show you how far mine are. Just took them today.

 

Yes Mazdatrix are gay lazy bastards. They say they do not have the money to spend on tuning a 6port ported housing when the two ports are made into one large one. My engine is almost done so I will let everyone know in a few weeks after break in period how much power it makes.

 

Von, did you actually read what they had to say about that port? The problem was with the power peak being beyong the limits of the engine. That port has roughly the same duration as a PP, but opens(and therfore closes) a good bit later. I hope you built your engine for 10K if you plan to use the powerband from that port...

 

I don't see why just making the two ports 'join up' with each other would raise the powerband much..
I would've though that only if you made it open later it would raise the powerband?

 

Why not just start grinding away however you wish? Since those people who have been doing mods for any number of years are not up to your standards, just grab your grinder and have at it. Let us know how it turns out.
