Topic worth discussing.

[muscles]

Alright after searching through the site i have been trying to do some research on our intake manifolds. Mainly because i feel like there is some real potential for our engines "n/a". I was talking to my mechanic about some dream swaps/ conversions to do to my engine when he recommended throwing on a skunk intake manifold on the engine. After going to there site; surprise, surprise they do not make one for our cars. But for someone that is a little more mechanically inclined and more experienced than I spot one of there products off a lancer that may bolt up?

So far the only progress our platform has seen has been trying to fit the lancer/galant intake manifolds onto our engines. http://club4g.org/board/4g-eclipse-gs-se-specific/20200-4g69-intake-manifold-variations.html How ever there is a loss in hp and a gain in torque.

The other option is to PNP our oem stock manifold. How ever there is not a lot of feed back concerning this and no dynos showing the increase. http://club4g.org/board/4g-eclipse-gs-se-specific/6480-ported-polish-intake-manifold.html So basically just a lot of speculation unless i missed a thread showing otherwise.

So mainly the focus of this thread is to reach out to the board and post up on anything that y'all have done concerning our intake manifolds. Ha at least this isn't another "which intake is better?" thread

Trevroar did a write up on a lancer im swap pretty sweet he confirmed that you lose hp but gained a sufficient amount if torque! He is still running it if I'm not mistaken

yea i have read up on that thread as well. Not to much feed back on it though. Id like to see Skunk make us a IM to bolt onto our cars. From what i hear all around we would see a lot of power and engine response.

skunk will make it if they see a demand for it. weapon r makes nice sheet metal intakes too

thats what i figured. I tried emailing them but kept getting an error everytime. Ill check out weapon r.

[dsm2mivec]

I'd love one if it was affordable

yea that would be the key word "affordable" lol But over time i could definitely see a company like skunk to make a nice bit of profit from fabbing these up. I mean they have been around for quite some time.

Yea, check into it, I'm In-- CHOP

Plan on it. Ill post what they say. Feel like everyone should send an email. Might spark there interest.

What's wrong with the Lancer RA ported/polished manifolds from RRM?

RRM MIVEC Engine Ported/Polished Intake Manifold [RRM Intake Manifold Ralliart] - $379.00 : Road Race Motorsports, Mitsubishi Suzuki Fiat Hyundia Performance Parts

If porting an RA manifold leads to increase in HP, it probably means that the Eclipse manifold holds more volume.

there is a thread on that im and people have tried however they said that it wont fit. We have one more sensor on our manifold apparently so i am not sure as to how much that would come into play for our ecu.

If they will make it, then ill buy it

Hi Ross,



Thank you very much for the inquiry.



We are always interested in new product suggestions.



We are just barely starting to branch out from the Honda/Acura scene and start looking at different makes of car.



What I will do is forward this request on to the guys in R&D. If they decide at some point that there is enough demand for something like this we will look into developing it.



At this time I can tell you we are up to our eyebrows in new product development so if we DO decide to do something like this we would not even consider starting until sometime next year.



Keep an eye on Skunk2.com for new product information to see if this idea made its way into production.



If you have any questions let me know.



Thanks again for the suggestion Ross!

Theres also a site that sells the flange for the 4g69 to make headers, think we could get something like that to make an IM?

Shoot, why not pnp an eclipse IM and see the gains? If i had the cash, id have done it

[Gravey]

no need to polish just get the manifold extrude honed and port matched. polishing is good for heads but "dirty" air in the intake runners leads to better fuel atomization.

Send them an email. And let us know what they say.

For the members who have pnp an eclipses im they haven't posted or had a dyno afterwards showing the gains. Eventually if nothing comes from this thread ill go the pnp wayy.

[clipse4gs]

nice muscles, im digging this thread!

[akley88]

im getting my im port matched when i do the head and cam

Sick are you doing all of those mods at once? Or one at a time because i would be interested on how pnp the im would feel. Either way let us know what you think man after you got it done.

ha thanks man. Tired of seeing other threads that arent really motivated to expanding knowledge/availability for other parts.

[clipse4gs]

4real! lol this was def worth discussing, now to find the right people to make it happen!!! have you contacted weapon r or just skunk?

[muscles]

just skunk so far.

[clipse4gs]

word, im not sure about how i feel about weapon r though, seeing that their intakes for our car were pretty shitty lol wish we could get skunk to jump on this shit...preferably sooner than later but you know how that goes lol

[muscles]

the only way to speed that up would be to mass email them and show a lot of interest in these being made.

[clipse4gs]

agreed

[muscles]

So was talking to my mechanic and I am gonna see if his friend will be able to fab up an IM. But to check back in with em today and I'll post back any good news. If this falls through then going back with pnping the oem one. :/

[mrgibs121]

unfortunately intakes arent as easy as headers... theres lots of fiddly stuff to think about with proper airflow, runner length, overall volume and so on.... if youre thinking about trying to have one made, make sure it is close to the same volume and runner length... honestly tho unless its really really well done you probably wont gain anything... im looking into getting my head ported and polished and decompressed while the car is off the road this winter... i think a great idea for the NA guys would be to get the head port/polished and shaved to bring the compression up to like 10.5:1... that would be a whole different engine right there

[FeaRlezZ]

^ i agree go with head work that is well worth the money. working with the manifold will b extremely tedious and u will probably not achieve any difference from the lancer manifold.

I agree with you too, head work is most likely going to be much more important for us to see gains. However, where will you go when you have already finished doing what you want to do with the head? It's the whole little bits add up thing. If we had a manifold that cost a few hundred, and gave us like 9 or 10 hp&tq, i think we are all dumb enough to waste our money on it

[mrgibs121]

^ dude i completely agree with that lol but its going to have to be from some actual aftermarket company that can design and test one for flow numbers, resonance problems, proper air inlet speed, sensor location to prevent throwing codes, all that kind of crap... its a big deal to do the R&D for this particular component of the car... that being said if one becomes available ill be all over it lol, especially a long runner high velocity style one because i think it would take MIVEC to a whole new level

Also, as already noted the intake manifold stuff is something that will take a little more "know how" then simply fabrication. You need to consider runner length, diameter, plenum volume, and TB opening just for starters.

From the work we have done with the V6 platform we know the longer runners have been showing excellent increase in torque within the upper low to mid range RPMs. The OEM 6g75 intake manifolds have actually been shown to improve about 15whp on the 3rd Gen Eclipse platform whereas the Diamante and GTS manifolds show less HP and torque. The 75's manifold design is also a bit different since they angled the throttle body flange instead of a 90* position to the intake runners. This is something you will want to implement if possible.



The Xcessive intake manifold that was made for Bj's (boostzealot) 6g75 swapped Galant to use the Infinity Q45 TB. We have been running both the 6g75 intake manifold and the Xcessive manifold. The 75 has way more torque in the low mid-range RPMs, whereas the Xcessive has more upper mid-range to high end response.

This is because of a couple things, the Xcessive intake manifold has intake runners that are approximately 10" in length, and the 75 has intake runners that are approximately 12" in length. Now before you say "it's because of the bigger throttle body," we prepared for that as well and had an adapter flange made for the 75 manifold to have the Q45 TB bolt up to it.



Now since many of you would not be able to, nor really need to run that large of a TB, you still have the benefit of using the GT throttle body to improve the GS's restriction point on the manifold. Keep that in mind for your plenum's TB flange.



If you have any more questions, I will try to answer them and maybe help point you in the right direction for some other key pieces of this puzzle

[mrgibs121]

guys check this out:
EVO VIII intake manifold on a N/A 4G69 - evolutionm.net

if anyone is crazy enough to try that shit id love to see it... maybe i will be the guinea pig in a few months who knows.

[muscles]

this is what my mechanic told me thus far.

"were gonna have to decide on dimensions. THe central plenum volume needs to at least equal the overal liters of the engine and the runner length determines throttle response and torque. Longer runners make mroe torque at the expense of some throttle response."

I trust my mechanic he knows what hes doing. Ill keep yall updated of course. I rather give it a try and maybe get these brought to the community once i have dyno'd and all. Be cool to be able to bring something to the club.
