RVR vs EVO lll Manifold

[Aproductions]

I need to know what the differences are between the 2 intake manifolds..


everything from TB sizes, head sizes, and like how many vacuum sources they each have.




and sorry but I'm not paging through that insanely long thread that I know everyone will tell me to search.


please and thank you.

I have compared side by side the genuine evo 1-3 with the same manifold from unknown vehicle. The unknown vehicle had 54mm TB . I couldnt find any difference in the manifold itself. I dont know who started this roomer the RVR mani was different from evo 3. My bet is its exact same casting.

 

[Colt4G63 also]

I've installed one of those JDM RVR engines in a 2g before. The manifold didn't have a MAP port, so I put the original 99 GST manifold on the JDM engine. I would have to assume the EVO 1-3 manifold has the big ports because it's a 6 bolt right? The RVR one that I saw was a 2g style with the narrow intake runners.

I think the only main difference is the RVR has a 52mm tb opening, while the EvoIII has a 60mm. Neither have an EGR provision.

The Evo 3s were 7 bolt motors, so both manifolds fit 2g heads.

You are too good to waste your time reading information and would rather be fed.

-RVR intake manifold has smaller TB opening (2g TB) vs EVO has opening for 1g TB
-RVR has 4 vacuum ports IIRC vs EVO III has 5

Also be aware that there is an EVO I/II manifold too that is slightly different. The I/II has the larger TB inlet, 4 vacuum ports and no EGR.

I have both manifolds and they both have 4 vacuum ports.

I also measured the volume of both of them. They are the same. As stated the Evo III has 60mm TB and RVR is 54mm. Both of mine have no EGR but there are pics of them with EGR.

I wonder why I start threads to help others out....

BTW, certain manifolds do have "EGR provisions", just not what we're used to seeing.

 

[eeeewidner]

The JDM 6bolt I have has provisions for an egr.... The tb has 4 vacuum ports.

How much are these worth nowadays?

 

[95eclipser]

How much are these worth nowadays?

About $140-$200 depending (Evo 3 60MM)

-Ebay is usually $150 shipped for evo 3. But most of the time it doesn't come with coil pack brackets.
-I found my evo 3 used with brackets for $180 delivered. The brackets tend to be expensive, so people either tuck the coil pack away, or make their own.

Evo III manifold had provision for EGR, but was plugged from the factory via a banjo fitting w/o holes. Design-wise, the RVR and Evo III identical with the exception of the TB opening as others have stated.

My Evo manifold doesn't have that banjo bolt, could it be a Evo I or II?

All evo versions had the 60mm TB opening in the plenum so if you have a unported opening then yes. Besides the EGR it's the same thing although I believe there are a possible difference in the number of the small vacuum ports.

I have sold 1-2 RVR intakes with the TB inlet opened up to 60mm. They do not feature the EGR provision. I have also seen a couple EGR provisions welded closed as well.

Evo 1 and 2 have no EGR, evo 3 does because of the year released, japan and europe required cats and emissions then so it had to have it,

No different between all 3 apart from evo 3 having egr and 1 extra nipple port on the far side of the intake plenum

Totally no offense to anyone.
The hole on EVO3 intake manifold was not for EGR. It was a part of that year's antilag system for WRC. Mitsubishi had to put it on EVO3 because the WRC regulation but never activated the function commercially.
As mentioned above, EVO3 intake manifold has one more small vacuum port on the timing belt side. just right next the freeze plug, 5 vacuum ports in total . EVO1-2 has 4 ports in total .
EVO1 and EVO2 intake manifold are the same, have the same part number.
JDM Eclipse also don't have the EGR, neither the MDP sensor. because exhaust gas regulation is different in Japan. Even no holes for those on intake manifold. ECU still has pins #6 and #73 for those but wires are deleted from harness by Mitsubishi.

P.S. I have an EVO2 intake manifold for sale, if someone is looking for.

one the later evos, these ports were called the SAS - secondary air solenoids, which they used for misfire/als/"pops n' bangs"

Right. I think I wrote it in another thread before. In Japan, people call it second air system.

Exactly correct. The banjo bolt on true Evo3 manifolds was not for an EGR, but for a Secondary Air System--a primitive antilag system. To meet homologation rules, Evo3s came from the factory with all of the necessary provisions for the antilag system Mitsubishi used for WRC, but it was disabled from the factory (the banjo bolt on the manifold only had one hole, blocking off the port, and the software control in the ECU was deactivated).

Besides, the SAS port, the only appreciable differences between a true Evo3 manifold and an RVR manifold is that the TB opening is 60mm vs 54mm on an RVR, and there is an extra vacuum nipple on the driver's side of the manifold. Evo1-2 manifolds have the 60mm throttle body opening, but no SAS.
