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

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.

just the left one? :D

chdesign September-5th-2002 09:34 AM

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:

Sil_Pro5 September-5th-2002 02:47 PM

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?

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?

Patio September-5th-2002 05:09 PM

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.

if youre keeping the stock manifold, the main thing is to just clean up any casting marks, and gerenrally clean up flow. Its not until you hit the ports does it get REALLY complicated.

Basically, youre trying to keep a good volume of air going in, at good speed, and without too much turbulence. If you check out the Tech Article section, the stickies at the top about intake manifolds will give you some general ideas of the goals.

Thank you
