Should I: Gut my 00' intake?
 

Alright guys simple question here. I have read a lot on gutting the 99/00' intakes and never got a straight answer (unless I missed it somewhere), but should I attempt to gut and port/polish my intake and throttle body? I want to remove all the emissions crap from my car and want to gain some top end with this new build.

I have a spare intake and TB from when I bought the spare 99 for my 93 car. Well after selling out and buying a 2000 SE I now have a spare intake and TB to play with.

Can someone lead me in the right direction if I am missing a post that sums everything up. I want to completely gut both the top and bottom, and weld the rest of the crap to make an open intake.

Some of the threads i'v read and have gotten no answers:

https://www.miataturbo.net/general-m...testing-66901/
https://www.miataturbo.net/engine-pe...anifold-38809/

I have never seen this topic summed up so it would be nice to finally get answers on this. Any help is appreciated, thanks!

I would do it after seeing the Gutted IM Testing thread you posted. I think most people will suggest the Honda intake.

If you can source a honda mani and splice the two together for not too much money (welding is usually about 200-300, and a used blox is about 100) I'd go that route.
If you want to stay low budget and try the gutting go for it since you have a spare.

The reason you've seen inconclusive results is because that's what they are. We have a handful of people that posted their testing, but many of them either had too many variables, or were unable to consistently repeat the gains on the dyno, or actually recorded a loss in midrange with negligent gains up top. Its still a hit and miss IMHO.

Why don't you try the dual runner setup that some were going to try, but no one has yet (that we know of)

Yeah, I think there was a noob, Pinky or something, that was going to try it.

I want to see how that works vs gutting the entire thing.

You should just utilize the VICs until someone actually dynos the dual chamber mod; that has potential.

otherwise gutting makes zero sense and has proven to provide losses, not gains.

It's was horrible gutting the thing and takes forever. Unless you're just ridiculously bored I wouldn't do it again.

What's the advantages of a honda intake or old begi intake vs a stock intake with vics? I can easily weld another intake on to the existing runners, sourcing another intake is the question, but why honda or begi vs a gutted intake?

Dude, check the manifold thread.

Stock IM has a giant bottleneck right behind the tb, and more restrictive runners and stock tb. When you gut it, you're just addressing like 1/4 or less of the "problem".

Honda mani the plenum is better, the runners are straighter, there is no crazy bottleneck, etc.

Older begi is not bad and similar but IMO the honda has a better/smoother design.

Get a blox or skunk2, splice together like everyone else, run 65mm tb and profit.

Guess I missed that thread

My buddy has a b series intake ( a skunk2 knock off) he will give me for free, would that be a good investment?

LOLOL redundant question is redundant

Easy killer I know nothing on these intakes lol

So read that excellent thread about those intakes.

https://www.miataturbo.net/engine-pe...anifold-43103/

Lets see:

- you have a spare stocker to hack up for free
- you have a spare honda to hack up for free
- you can weld it yourself for the cost of wire/gas
- ????
- The answer is......



....no definitely don't do it:giggle:

Question is about the b series intake, is it equally as good as a skunk or blox? Now that im off for lunch I can get off this dam phone and research lol

hahaha. doooooo iiiitt!

junk2 is a knockoff. blox is a knockoff of that. etc etc etc

Who cares. Its all still superior and an upgrade from our IM's.

DO EEET

the skunk2 and blox are just replicas of the ITR IM.

Here is said intakes I can haz, fo fwee, so you guys be the judge yay or nay?

https://www.miataturbo.net/attachmen...ine=1363713442

yay or nay? I'll give you an ARRRRRrrrrrrRrrrrrr

You know I don't speak spanish, in english please

im not even mad, im impressed.

So yes on this intake? Looks nothing like the others.

P.s. I could go all day with anchorman quotes, brain.

its the pants!

do me on it.

Works 60% of the time, everytime

I love lamp

Where'd you get those suits.. at tha... toilet.. store?

You have a massive erection.

Bears can smell the menstruation.

I immediately regret this decision.

they named it San Diego, which of course in German means a whale's vagina.

About that intake

I'm not a baby, I am a man. I am an anchorman.

boy, that escalated quickly

I stabbed a man in the heart.

Agreed. I'm answerless yet amused at the same time.

Also its cold in Moscow, you may need a coat

:laugh: @ all of them

How does it feel
When you're alone
And you're cold inside

Here abandoned in my fame
Armageddon of the brain
KGB was doggin' me
Take my name and just let me be
Then a begger boy called my name
Happy days will drown the pain
On and on and on it came
And again, and again, and again...
Take my name and just let me be

I can see it in your eyes,
I can see it in your smile.

You're all I ever wanted,
And my arms are open wide!

And you know just whay to say,
And you know just what to dooo

I have to tell you somethin....
How about that intake?

get a room already you two

Tuned in to see 40 post thread on intake manifolds blow up in a day.

Anticipated similar results.

Was not disappointed.

There's room for more, Vlad

I really have no idea about the intake but I will give you my ignorant opinion since you can't seem to get anyone else too.....
Best I can tell that is a stock B18 intake which will work, and prolly be an inprovement over the Mazda IM. IF you read the Honda intake post you will see people are using a Blox or Skunks2 IM which really looks nothing like the one you can get for free.....
SKUNK2 Intake Manifold 68mm Blox Tuner Throttle Body B18C1 94 01 Integra GSR | eBay is the SKunks
Blox Intake Manifold Acura Integra Type R B18C5 DOHC vtec Bxim 20100 | eBay Blox
94 01 Acura Integra B20 B18A B Big 70mm Air Intake Manifold Cast Aluminum JDM | eBay what I bought....
If I were you I would, actually I did, Buy the cheap IM for the B18 and weld the flange from the NB IM to it JUST LIKE EVERYONE ELSE IN THE HONDA INTAKE MANIFOLD THREAD DID........seems to be a good idea to me?

Hey now, no reason to raise your voice up in here. I know they look completely different that's why I wanted feedback on it.

LOL......sorry

Thats my main concern about it. If I wasn't currently pulling my engine I'd be researching lol someone help out here!

With zero visual cross-referrencing on my part, I think the Honda manifold you have is a 1994-2001 B18B1 intake (140 hp Integra LS non-VTEC).

It would be a slight improvement over the 99-00 Miata I.M., but not worth the work IMHO.

Like 18psi said, source a ~$100 Skunk2/BLOX/AEBS/OEM ITR etc B-Series Honda intake and splice your 99-00 manifold for great success.

That's exactly the intake he has, he just told me. Now time to source used or man up and buy that skunk2 and TB combo.
