Lancer Evolution III Intake Manifold

[FIBA M - EC17PSE]

No from the first pic I uploaded it's been filled in and welded and smoothed out. Doesn't look like yours.

oh ok sorry i didnt click on it and was on my phone viewing so not the best of pics any how, looking at your other pics not I am on a comp you have the nipple on the right near the core plug so it is an evo 3 manifold and someone has filled it in on the EGR, makes it easier to cap off,

Well, I guess the mystery is solved. Either way, there is no port for the egr valve.

 

[Type1DSMr]

Yup mystery solved. Thanks gentleman.

 

[FIBA M - EC17PSE]

the Gang of the mystery incorporated solved the case again!! hehe

mine has the threaded port for an EGR valve so I guess it's a true EVO III manifold. What size (thread type) plug do I need to block it off?

I used an M16 with a 1.50 thread pitch. I could not find one short enough, so Put a nut on and cut off what I didn't need. Removing the nut cleaned up the end. I used thread locker and a washer for install.

So I have question. Would a bored out 57mm 2g throttle body work fine with the 60mm Evo 3 manifold or does the 3mm make that much of a difference? If I have to get a 1g throttle body, what would I need for the throttle elbow besides the coupler to fit a 2g vrsf intercooler kit?

 

[2gmitsueclipse]

You can mount the smaller throttle body without ill effect. It is an issue when you mount a larger bored throttle body to a smaller intake manifold inlet.

 

[FIBA M - EC17PSE]

^^^^^^ exactly right. If you was to go the otherway around some taper porting will be needed but using a 57mm on a 60mm hole is fine and wont cause any issues

 

[Type1DSMr]

Well unfortunately, Steve from throttlebodys.com doesn't do the 57mm upgrade, however, he made me a great deal on a rebuilt 1g tb I might take. So if I go that route what do I need to make it work with a vrsf intercooler kit? Could I just cut off the flange in the throttle elbow to hook into the coupler? I would like to keep use of it because I have my iat in there.

 

[2gmitsueclipse]

Does the kit require the 2g intake elbow?
If so, you can taper the flange section to open up to 60mm. You can use the supplied gasket from Steve to mark how much you need to open up the elbow. Do this only at the flange, as there is not enough meat to taper/port past the flange.

Sounds good I can do that. I thinking of the NT tb that use the coupler not an elbow.
So the 1g and 2g elbows have the same bolt pattern but just different in the size of the openings and angles, correct?

Yes, direct swap.

 

[Canadian_CD9A]

Are Evo TBs really that hard to find?

 

[2gmitsueclipse]

Well, in the states, they are not as common as 1g or 2g throttle bodies.

 

[Type1DSMr]

So do you guys use an oem 2g intake gasket or a heat barrier gasket for your Evo manifold?

 

[2gmitsueclipse]

An OE gasket is fine. The thermoplastic ones don't perform all that well. A phenolic spacer/gasket would be fine, but can be pricey.

 

[FIBA M - EC17PSE]

they have been known to leak or break and some even last 1 time! a normal gasket is just fine

 

[Type1DSMr]

Where did you guys bolt your noise capacitor from the 2g manifold? The Evo manifold doesn't have a spot on the side for it.

 

[1990TSIAWDTALON]

Put it on the top 10mm bolt closest to the drivers side. Just a note for anyone using a EVO3 intake, the 1990 TB won't seal correctly so use a 91+. Mine is blended and I use a '91 model TB with some adaptor harnesses for my TPS and AIC. Pulls great to 8500+.

Here is the plug that I bought for my Evo 3 Manifold EGR port, and with a little RTV is works great!

I just had a plug welded in mine. Also has the custom mount for bolt on install of the omni 4 bar.

I'ver been using my evo3 intake manifold for quite some time now (~3 years). It works really well and looks great. This is with an FP HTA88 and Water to Air intercooler. I managed to get lucky and get the factory bracket for the coil pack also. I will say that if you have the factory bracket, the types of coils that fit in there are "odd".... the screw holes don't line up with most of the coils I have in the garage but I had the set that came with the bracket too.... anyway, I highly recommend this mod and it appeals to the sleeper look since it doesn't appear to be anything other than a stock manifold to those uninformed.

has anyone switched from 2g intake to an evo intake and notice a tq loss in the 2000-3000rpm range? I ask as I am running an a/t rvr engine. I am seeking ways to boost the drivability a bit. considering swapping in the 2g mani to see if I like it better.

arnt the rvr intakes smaller anyway in bore size, ive not done the swap yet but i believe they are more for better top then then lower down on the power range
