Intake Manifold - Port & Polish
 

anyone know how much HP increase i should expect? Im getting my throttle body bored too.


I'll have a spare Ported & Polished Intake Manifold & Bored Throttle Body once Im done with this ;)

How much are you paying for the port and polish?

How bout you do your P&P and I will make my own custom sheet metal manifold and we will compare gains....along with a direct port Nitrous system and my High Compression Pistons.

I may be tearing mine off shortly to take a look at something. After looking at the dynos from the the FM turbo project and MP3 ECU graph, I'm thinking that part of the power difference between the cars is in the intake. The only thing different between the manifolds is the lack of VTC on the MP3. I may just remove the shaft and the butterflies from the VTC and plug the shaft holes. That might be worth 5 HP or so judging by the differences that the ECU makes. It's just a restriction that's not neccessary anyway since all it does is make noise when cold and get in the way once the engine is warm. It won't throw a CEL as long as you leave the solenoid hooked up. It will definately throw a CEL if you disconnect the solenoid.

how about, nobody cares about what youre going to do? :confused:

yeah, we'll compare specs when i have that Rotary RWD RX7 layout done :rolleyes:


thanks for the info Pseudo :D Im hopeing to get this done soon, i got the cash, just waiting for that new job to line up

OK jackass how bout you lick my left nut

What the hell is your problem? He's just trying to pinpoint how to get the most HP gains and you're telling him to go screw himself.
:rolleyes:

just the left one? :D

As far as I'm concerned he can lick my ass while he's at it. He goes and brags about his setup all the time on here then when someone proposes the idea of someone having a better setup than him he gets a corn cobb up his ass and has to get all huffy about it.....and where the hell did the RWD RX-7 thing come up from When I was talking about a sheet metal intake, High Compression and direct port I'm wasn't joking I'm doing that...does he think i'm incapable of making my own intake do I need to remind him I made my own turbo kit for my car and I've made sheet metal intakes before for 1.5L british Leyland motors???? I mean come on Patio wooo hooo you hav ea 75 wet shot we all know this but you know what else ANYBODY can slap a N2O kit on and go around and say you can't beat me i've got NAWZ!!!! Now I can say that hardly anyone anymore will come up to you and say hey man I can beat you on the spray with me ALL MOTOR. Get ready boy cause the all motor 1.8L Is comin to whip up on your Nitrous ass.

Of all the people on this board that I have met, only a few do I respect. And although these few may make some smart ass comments now and again, for the majority they KNOW their junk!

They also offer critiques when needed and try to paint two sides to every story (like ANY logical and educated person SHOULD). But, when people become hostile towards another member just because that person is offering another side to consider, that hostile person looses credibility.

Again, there are very few on this board that I respect for their knowledge and although I have had difference due to their personality, I still respect them highly. They are: PseudoRealityX (We really should get together sometime, since we both live near Atlanta, Georgia.); Traveller; Chdesign; TheMan and many others that I cant mention because my 5mos. little girl is going bannanas(sic?)!

These people are very knowledgeable and usually try to offer another side to consider, even if its just to play the devil's advocate, or, so to speak...

What Im saying is this: Before you jump, at least have something to jump at-cool? Chdesign, in no way came across as a jerk or cocky in any way. Nor was he trying to 'down' you. He just offered another side to consider.

Please everyone, I know we cant like each other all the time but, we can atleast RESPECT each other ALL the time, or until someone deserves to lose that respect.

Sorry all for the rant....but just to add.......I have always thought (esp. after looking at the TB the other day) that the intake system was the largest and most glaring problem we have w/ the FS-DE motor. By intake system I mean, ALL of it. the MAnifold to the filter. Lets keep the idea goin' guys!!!

LOL, since when did i brag about my set up? its a VERY COMMON SETUP FOR ANY CAR!!:o

all motor? have fun in the 15-16 second class ;), youre gonna be there alot longer than you'd like to think, hahaha

the problem is, everything you do to your motor... guess what! I can do to mine, except for those minor mods where i have my motor set-up for spray! :o oh no, did you ever think of that?! :eek:

Im having a Mild P&P done for 100 bucks, most likely ALOT less, it helps knowing alot of people in the scene ;)

would you like it if you posted something and only had a question and I came in and said "youre shit sucks, youre a fucking moron, just wait til my set-up is out, ill show you, you fucking idiot" would you now?

Im glad i pissed you off, hahahhaha, cuz truthfully i dont give a fuck:rofl::laugh:

Some P&P jobs get really expensive. Its really a matter of what you need done to it ( i.e. How much to remove, etc...). However, A bored out TB w/ a new plate runs around $150 for Honduh's. That with you sending yours in and etc.

I would think that a cheaper alternative is to get an FS-ZE intake manifold and see if the TB comes w/ it. I think I saw that corksport has one for sale w/ a TB for $500 USD. Whether thats a good price or not, i dont know. But i would think that if you could get one w/out a TB attached that it would be allot cheaper. (& I have been thinking of doing this myself recently).

Lastly, so long as you are careful, you shouldnt have any problem doing the port and polish yourself.

Does anyone know, exactly, how much larger the ports are on the FS-ZE manifold, compared to those on the FS-DE? What about the intake and exhaust ports ont he FS-DE head compared to the FS-ZE head?

c/j

I am not very familiar with the process of port and polishing. What exactly is done? do you make the runners themselves wider? and then polish the casted metal to allow the air to rush through the intake manifold easier?

I didnt start it, but this isnt 4th grade, I aplogize for the crap Ive put on yalls forum. I was just trying to get some info.

Thank you

Actually dude yeah you did start it and I'm going to drop it at that. As far as you can do what I can do. Well thats great but I've said it before ANYONE can slap on a Nitrous kit but how much good is your N2O in the twistys?????????

OK OK I'm sucking it up :red: and i'm dropping it now :squint fi

Patio- Are they going to put it on a bench and test the intake before and after? I'd be interested in the flow numbers the intake makes..

And home porters.. it's not rocket science, but if you get greedy or don't measure twice, cut once, you can end up screwing things up royally.. Uneven flow, etc..

And chdesign.. don't worry, it'll rain in Houston again soon, and we'll be back for Chapter 3 of the story.. ;)

You guys are funny:fight: :rofl:

Dont we have a flame tread around here somewhere. If not we should make one. I like reading peolpe bickering.

I haven't seen any exterior differences other than there are no holes drilled for the VTC on the MP3 manifold. I think you're thinking about the variable intake control. I'm talking about the variable tumble control that's right next to the ports on our cars. The MP3 only has one control soleniod and no VTC or any holes for it. It's attached to the upper intake right next to the intake ports on the head. It's what makes our motors sound like a diesel when cold.

I'm thinking about removing it, tapping and plugging the holes, and seeing what happens on the dyno. It's a restriction in the intake right before the head. I would think that I would gain power everywhere since I'd be removing a restriction. It remains to be seen. I'll take it apart soon and see what I think. I may take a pic or two when I do. I still have to put my Greddy e-manage on. I just got switched from working M-F to Tues.-Sat. so I won't be able to do it until Monday probably. Good news is that I got hold of Greddy and they said to ignore the hook up drawing that came with the support tool set. We DO NOT need a limiting resistor on the MAF circuit. That was just for J-spec cars. Also, I have the rotary switch settings if anyone else decides to go this route.

Just a pointer for you Patio if you do get a Port and Polish make sure that the Flow test it. If one cylinder flows more than another you will most likely end up with one cylinder lean and if you are spraying this is especially bad.....Fuel Injectred Port and Polish isn't like a carb 4 banger where you can pretty much whip out the dremel tool and go at it.....to do it right you HAVE to have a flow bench in order to match every port which is one of the purposes of P&P.......oh yeah 100 bucks you must really know someone well it cost me close to 600 for mine but that was also with a 3 angle valve job.

here is a picture of the tumblers found on the 2001+ miata intake. i would suspect that the protege manifold is similar.

Hey, wait a sec.... those plates look as if they are screwed on w/ two screws and if so, then why not just unscrew them and take-em' off? I know there will still be a rod or something on which they swivel that is "impeding" the airflow but......would it REALLY be that significant? I mean, unless one is really changing the size of the ports, it really wouldnt matter-or am i wrong here?

I just think that it would be much easier to only have to remove those plates rather than tapp and plug holes and the such.

c/j

sounds good to me.

I think I remember seeing SCC mag try that on a project miata and they ended up losing a lot of low and mid range torque.

was it the VTC or the VICS? they are two completely different things.

Here's the link to the article.

yeah, thier project miata is a 99, which only has the VICS system on it. mazda put the VTS on the 01+ miata intake manifolds. the VTS is a totally different animal compared to the VICS.

It needs to go. I'll have to see about taking the manifold off and plugging the holes.
