![Question](https://www.rx7club.com/images/icons/icon5.gif)
I have been looking all over for info on this. I have already Ported both of my side housings & my exhaust ports. But I have been confused by multiple web pages I have read... some talk about porting the intermediate housing ... is this correct? I have not touched my intermediate housing ... the template I have looks huge lined up to intermediate housing port.
Is this common practice to port both side of the intermediate housing? Or am I way to tired to be thinking about this? Is it the drugs?
Thanks

"It depends..."
For all out power, port all the ports.  People leave the intermediate ports alone for better idle, although my experience has been the opposite - I find porting the primary ports have no bearing on idle quality.

So, I have a racing beat street port template I used for my side housings.. Is it safe to use that same template for the intermediate housing? They don't sell a intermediate housing template .. so I assume its the same? I just looks darn big I am going to be cutting alot of metal... is this right?

no you dont want to port the mid housing with the same template you used for the front and rear. The intermediate ports must remain smaller than the F&B..When i had MAZDATRIX port my new housings they slightly port and polished the intermediate ports..

I think if you read the Maxdatrix porting page it mentions there is not alot of material around the 2nd gen NA intermediate housings ports. Be very careful if you do port those.

Ya, thats what I thought... the picture makes it look really bad. I think its cause it was in a dark garage with the flash on ... the flash just refleced those groves alot. It looks nowhere near that bad in person .. they meet the specs acording to Atkins Rotary's rebuild video.

I don't know about TII intermediate housings as I have no experience engine porting yet. I just know what Mazdatrix wrote about the NA 6 port intermediate housings; they didn't write anything about TII ones.
(edit) you can email Mr Lemon at Mazdatrix. Despite what people have said in the past, he has always been helpful and courteous to me. Be brief and specific, I'm sure he is a busy guy.

I would at least extend the top part of the primary port to match the secondary port for big power applications.  All my port jobs, I usually port the primaries as big as the secondaries though - it doesn't hurt.
