My N/A Intake Manifold

[Mazda_Powered]

I was asked to post some pics of my manifold. Here's what i've done;

Bottom 1/2 was 'cut', fully honed, ported, and lightly polished.
Top 1/2 was 'cut', ported, knife edged and polished.

Should flow alright.

The pics for the top 1/2 turned out worse than ****. So you all can use your imagination, plus i dont wanna give away the cut manifold secret

Lookin good jack. Not a fan of how shinny it looks but that's just me. Let me know how it feels with the new power gains.

nice jpb, but still needs work

you could remove the "scaring marks" from when it was bored/honed out

be supprised how much that can slow the air speed down
you want the inlet mani nice and smooth...but the head to have a "rough spot" so the air can start to tumble into the cyc

nice paint job

my N/A one needs a paint now...

How mutch would that do to the power?
And how much did you port out of there?

why is the cut manifold mod a secret?!

its for people with deep pockets

[smoke187]

i think its because ryan wants it to be a secret

it's a CP service, i'm now allowed to tell anyone about it. I believe if you're a paying member you can view the how-to? im not 100% sure on that one though.

got the intake manifold off the car tonight, only took me an hour and i didn't even jack the car up! go me!

Paying members can see the how-to and pics. I did mine a couple of weeks ago. We shall see if it makes any difference. The idea is that it allows air to flow better during the opening of the VICS butterflies so that you don't have the (I think it is ~5hp) drop while they open. Mine is shinier (inside)! I was going to paint mine too, but got lazy. That MAZDA logo fits perfectly, where did you get it?

yep although i knew about how to do it before i became a paying member although i did buy a cut mani off of ryan so....


dang that last pic it looks shiny in there!!!

[Mazda_Powered]

that's what i'll be going for with the one i'll be working on, just won't be tonight...super dead from the new job.

the mazda sticker is off the same year rx-7 that has the B code VAF we can use. the sticker is on the airbox, i had to trim it a lot. full metal sticker ftw!

started the cutting process today, stupid rotary tool is acting up though. so it's taking its time. bottom 1/2 took me about 20 mins, top is probably going to take over an hour.

well i finally finished it today!!! just have to finish cleaning it up, and give it one last wipe down with zippo fluid (works amazing). i'll borrow my sisters camera tomorrow and snap some pics

...needless to say, this being my 3rd intake manifold...that this had to be the worst one to port match. at the lower section (non vics part) the one 1/2 of the manifold was overlapping by about 1/4"...which is horrible! so now its all fixed and ported, polished, cut and port matched...didn't hone it though. not enough $$$
