hmmm... why does the part where the water neck attaches to look the same as a 1g head?

 

[99dsmGST]

Ok since I couldn't find any more Evo3 IMs, who is willing to sell me his or hers? I have a 1g IM, currently a 2g IM (still on motor). So if I can get my hands on a Evo III, I would post some pics and actual sices to compare all three.

after reading 9 pages....
i think i have found what i want to buy next, thanks for the info guys.

 

[95CarbonEclipse]

Anyone here that got the EVO TB with their mani going to rebuild it to make sure that it is free of leaks? If so, what all are you planning on doing to rebuild it?

Ok guys.
So this weekend I finally have time to install my intake manifold. All steps will be documented with pictures. For anyone who is LAZY and not interested in reading the prior 9 pages (you really should) I will be installing all the things that you would think would be installed with one of these manifolds. Please remember that when I reference locations under the hood, they are on a 99.
Going in will be:

Evo1-3/RVR intake manifold,
1G throttle body(rebuilt, shaft seals replaced, and painted),
hondata heatshield spacer.

I will then do another dyno at RRE as soon as I can and we will see what the gains are.

A few notes before I begin and any last minute comments if I forgot anything.
One of my main goals was to not throw CELs even though the car will run fine, I don't want to look at them. After figuring out the routing on a friends 2g intake manifold, Ive discovered that I SHOULD be able to run all emissions equipment, while tricking the EGR into thinking it is doing its job.

The EVAP purge solenoid(drivers side under the coilpack) will be mounted to a similar location on the new manifold. The stock 2g igniter mount will be mounted off a bolt hole on the EVO coil pack.

These items will be driven by a T off the throttle body E port:
EVAP purge solenoid VAC/PRES
MDP(with vac line running to it)
and the EGR vavle will have a block off plate installed and a line run to the side that WOULD see VAC/PRES.
The EGR valve will be mounted from the rear brace, pointing inward to look as though it is connected and functioning.
The stock 2G rear brace will be modified to work with the new intake manifold(holes 1/4 inch wider, +/- 2 inch spacers and longer bolts) I am not using the EVO/RVR rear brace because it is made for that block which seams to have a different mounting location from the pictures I can find. (someone give me one and I'll find out for sure)

By sending the same Boost and vaccum signal that the EGR would be fighting against and using as a reference to the solenoid, there SHOULD be no change in CELs or drive-ability.

The 2g TB elbow will be ported to match the 1G TB.


So, that's the plan as of now. I have 4/5 days to scrounge(or make) the last of the items I need to finish this project.
wish me luck guys!!

Goodluck! I can't wait to read the write up AND see the Dyno results!

Dan, I thought you were going to make the EGR system operational, what changed your mind?

Well I finally started to work on my mani, I don't have any before pics but it basically looked like all the others, well used & oxidized, etc. I will be getting it hot tanked to clean it all up internally but want to fab up a working EGR system first, which I will be sure to post up pics & details of. Mine is the evoI/II/RVR mani so I ported the inlet to match the 60mm 1g TB gasket & then got a little carried away & removed all the external casting flash between the runners to clean it up (even though you can't see it when installed ) I will more then likely remove any internal runner casting flash once I get it cleaned & can get a better look at it. I just finished glass bead blasting the mani & can say am very impressed with the finish it left (first time using this type of blasting media). Its supposed to be a satin finish & it came out as shiny if not more shiny then when new, I think it looks great, on to the pics:

PS: If anyone has an evoIII coil pack there looking to sell, shoot me a PM, I'm still in need of one!

 

[95CarbonEclipse]

^^^WOW! That thing looks gorgeous. That's just having it bead blasted, no paint or anything? It looks amazing!

 

[sd_ff22]

What changed my mind was the un-nerving idea of punching holes(and possible boost leaks) into the plenum. I figure if I can fool the EGR system, then I'll just do that.
your manifold does look great! It will probably dull out though due to air exposure. I bead blasted my old 14b compressor side cover and it looked great for about a week.

Yes, thats just bead blasting it. Am thinking I may get it powder coated in clear to protect it & keep it looking this way

The manifold looks great! Did you use fine or medium glass beads? Particular brand?

 

[95CarbonEclipse]

Does anybody know if the coil pack off of a GVR4 Cyclone manifold will bolt onto our EVO III mani's??

 

[95CarbonEclipse]

Okay... here's another question.

How hard would it be to modify the OEM 2g bracket to fit the EVO III mani?

 

[sd_ff22]

not hard.
there are two ways to do it from what I've found. one way is to use a pair of spacers at the back of the IM(brace needs to be widened by +/- 1/2 inch) or you could use something to raise the lower mounting point(on the block) about an inch.

I will see what will be easier on Saturday!

Sorry... I meant the coil pack bracket.

But it only fits in a right hand drive
Is it an RVR or EvoIII?

 

[NB4G63T]

That intake on ebay is on my car and it's not right hand drive.

 

[99dsmGST]

60 buck for shipping FTL!!!

 

[99dsmGST]

Here is a link to a cheap cyclone intake.

Cyclone intake

Hopefully a nice Evo 3 intake will come up on ebay any time soon. Been looking for one but no luck yet.

 

[sd_ff22]

That is an RVR manifold.
If you have read this thread you will know that it is practically the same part.
Why give us a link to a cyclone IM? I think its been proven 11ty billion times that they are not worth the trouble to hook up right.
AND we are not talking about a 6 bolt compatable intake manifold anyway.

 

[NB4G63T]

Ya sorry I didn't read the 9 pages prior to posting, but the one I have is a real one. They do look very similar until you see the tb inlet. Very informative thread as I've been wondering about the IM, I just purchased this car and i was unfamiliar with them before this post.
