Lancer Evolution III Intake Manifold

[Zex4g63]

So just to be certain, everyone that's switched says that this is worth it and a good upgrade for those wanting a "stockish" manifold w/o going to sheet metal correct?

I went from a smim to this manifold. Although my "stockish" manifold is far from stock inside.....

 

[pboglio]

Welllll.... what's considered "stock" because I went from a 6bolt intake to an evo3 intake/2g head.... I think the 2g intake manifold was a little shorter than the 1g intake.... or am I wrong.

Oh and btw, I did read all the pages on this thread before I ever posted in it . I just wanted to hear what people had to say, everyone just kinda... tapered off and didn't say much else besides "it rules"... I was kinda hoping for a little more technical data than that.... but measuring off the butt dyno is ok too I guess since that's the only dyno my car has ever been involved with and it seem to be kinda accurate (to me anyway ).

What kind of technical data are you looking for? If anyone is like me, they installed the manifold, datalogged the results before/after, raved about it for maybe 5 minutes on the forums, then moved on with life. I saw +20 h.p. average, then around +40 h.p. at redline and beyond.

That's cool... and I know not everyone will have the same results because of different other parts... but that's a decent gain just by switching to a manifold w/ shorter runners and a little straighter entry path to the head.

Thanks, I guess I don't have more questions... seems like everyone is satisfied with it.

Don't want to turn the thread into a "whoring out" but if anyone is looking for an Evo III intake or exhaust manifold, let me know.

Bit hard for me to answer that daren as I dumped all the egr stuff.That banjo bolt is just the end I used to fill the hole left, funny thing is all EGR's I have seen on Evo 3's the banjo bolt used for the EGR doesnt actually have any hole in it?? WTF

Heres another part of the extra EGR stuff that came on 3's only(I think)

The small canister on the right is what that extra vacuum nipple connects to.

After reading quite a bit about Evo anti-lag systems I believe that this may actually be what you are referring to not an EGR system. This quote was taken from page 3 if anyone wants to look at the surrounding posts for more context but it appears that the evo3 IM is set up for anti-lag that isn't used by the stock ecu (AFAIK). I was curious if anyone agreed with me that this setup looks something like that. From the evo 7/8/9 discussions the physical parts appear to be a branch off of an intercooler pipe, a canister, and a line running to the exhaust manifold. I also believe that the evo3 was the first evo to use anti-lag.

Now that we can use evo8 ecus and now that there is some disassembly going on of the anti-lag system in the ecu we may be able to convert our 2g DSMs to have anti-lag which IMO would be pretty cool. I know that DSMlink already does it but this actually controls lag between shifts in road conditions with considerably less wear on the turbo.

Just a thought, I would love some other input to see if we can put together some information on any of this and get a working anti-lag system going.

You might want to check out my thread here: True Anti-lag Systems. All the info I've been able to find on ALS is in there. That vacuum canister looks identical to the Evo ALS (SAS) system I have.

I just paid for my evo2 intake manifold and it's shipping from the UK. *Hopefully* i will be a member of this club soon

 

[underradar92]

Got mine a few months ago and due to my timing belt install faux pas, installing it and the 2g head will happen sooner than anticipated.

 

[redleader36]

yep. got the package today!
i am in the club now!

i cant wait to try it out!

 

[Rob10_99]

The real question is who's putting SMIM's on an evo2 in UK!

 

[jjrock5]

Well I installed mine during my march to june '09 build on my 97 GST, but never got around to posting pics, so here are some now.

I installed so many aftermarket parts in one shot that I couldnt tell wether the mani made THAT much of a difference. Its design says that it probably does... It's no SMIM but for the money, well worth it.

I installed mine yesterday. And I have to say, from 5000-7000 RPM, it's a whole new car. I also used a Magnus gasket. My top-end rips. I love it. And mid-throttle is so much crisper and responsive. I played with pre-3500 RPM for spool with awesome results.

For some reason my airflow dropped, though. Before and after boost leaks reveal throttle-body shaft-seals, so that's nothing new. I could hit about 35lbs/min and now my best was around 32lbs/min; however, the car is much faster. One thing I am noticing, my throttle cable feels a tad loose and it's pulled all the way. Sometimes, it gets stuck in WOT for a second. Not a good thing.

WOW JJRock, that gun powder gray color looks really slick. I like it a lot.

Excellent. That's exactly what I'm hoping to see once I get mine in hand and installed.

Those two things don't exactly seem to to reconcile, at least on paper. Is your peak airflow at a lower or higher rpm than before? Did you make the comparison logs on days where the temps were much different? I would expect the intake to have had the opposite effect on airflow, or at the very least to have held it constant. Intake pressure is another thing, though. Did your boost pressure change after the install? If so, did you 'reset' it to prior levels before logging airflow? I wouldn't think it would drop as much as adding cams would, but you are encouraging more flow at the top end, so I'm just curious.

The boost pressure stayed at 20. Peak airflow seems to be at lower RPMs. I do have logs of before and after. I can post them when I get home. I'm working the grave-yard shift tonight. The car can take more timing, and I rich-knock unless I'm around an 11.1-3 AFR. The intial torque when I go WOT at 4k hits so much harder. And it doesn't fall off anywhere. It feels like the power-band could cruise past 7k. I absolutely love this manifold.

I'm still excited about doing this swap, so pardon me if I sound like a dork, but the car is noticably faster and smoother! You'll love the part-throttle crisp-response, too. I can't wait to take it back to the track Tuesday. I used to have traction in 2nd, not so much now. I'm going to have to use my low-boost setting in 2nd gear from now on. And also, I used to have to be able to do a clean pull in 3rd, then knock in 4th. It just sails through 4th knock-free. You're going to love it.

Sorry if I'm not being technical enough, I'm not a very 'techy' guy. It's just that I've had my car for almost 8 years, so I know it well. I'm trying to give you as much driver-results as I can. Something you'll feel, not just observe on a log.

 

[matthewdesigns]

No worries about not being 'techy' . I'm just an empirical evidence kind of guy I appreciate the objective input for sure! I'd definitely like to see the logs if it's not too much of a PITA.

Good luck at the track...is the manifold the only thing you've changed since your last trip there?

 

[Dsmj89]

Where do you guys put the map sensor that used to be on top of the 2g intake mani now on the new evo3 intake mani ? I'm starting to get enticed to purchase an evo3 intake.

 

[jjrock5]

Many ppl just leave the sensor plugged in but hanging somewhere on top of the mani tucked in.

I basically made it 'functional' by buying a hose the diameter if the circular tip of the sensor, I believe like around 7/8'' ID, and teed into the brake booster hose behind the mani by the firewall. I used a beefy brass t-fitting that I bought at lowes. Simple little fix.

You and your evidence! :::shaking fist::: Hehe! Anywho, since that last time at the track, I did the manifold w/ a Magnus gasket, heat-wrap on the exhaust mani, and the heat-deflective tape on the j-pipe and IC pipes that are exposed to engine-heat. Of course, a new tune that I'm still working on.

I have DSMlink, so I did nothing with it. And since I haven't had an EGR for years, it was a no-brainer to just toss it aside.

Exactly what are the name/ part numbers, etc... of the grommets that go under the valve cover bolts

A local guy around here got an RVR motor and it had those grommets stuck on the valve cover...He pulled them off and I tried to put them on my stock 2g VC, They don't fit....I tried putting them on my spare valve cover, which is an EVO III/RVR valve cover not sure which has the 3 Diamonds and says Mitsubishi on the top and 16 valve on the bottom like in this pic...And they fit like a dream...I would think their used so if you do overtighten the bolts a tad it disperses the weight over an area.

[turbosax2]

The part number is MD327253. JNZ doesn't list them so I bet they're not available in the US.

 

[JFZERO ECLIPSE]

Damn, anyone from Europe able to get me some new gromments? Theres no US Mitsu Dealer that would happen to sell those would there be?

 

[90rslaser]

so why would you want a manifold with shorter runners? from my understanding, longer runners=more torque. and from my exoerience, dsm's kind of struggle making good torque numbers when getting more hp. someone correct me if im wrong about the runners. and im not trying to start a hissy fit in here
