Evo 3 DSM Intake Manifold yay or nay!??

[talonkid]

im wondering ...some local shop around here is selling a evo 3 intake manifold...saying its better flowing than stock eclipse turbo intake manifold...i have a 98 eclipse gsx...and i got oem intake manifold...im wondering if its a good upgrade to go wth the evo 3 or not? also is it bolt on ? they said yes...but i would rather make sure...also would i need to get a bigger throttle body or stock is ok or what? if anyone can help ### do so thanks

Should be direct bolt on like the exhaust manifold. 4g63 heads haven't changed bolt patterns but I don't know about runner size or placement.

 

[psi4mymitsu]

Are you talking about the cyclone intake manifold.

 

[95blackGsTurbo]

No he is refering to an intake manfold from a EVO 3. It is a direct bolt on.

 

[Stapl3]

The runners on that manifold will be bigger than the openings on your 2g head. Basically the air will be going from a big hole to a small hole and not smoothly, the air will be hitting a "wall". This is a poor idea and will probably result in loss of power.

 

[talon96tsi]

Anyone have pics of the evo 3 intake manifold? Or maybe a link?

 

[95redgsx]

I have an entire evo 3 motor in my car , it will bolt right up no difference in port size the only real difference I can see is that there is no provision for an egr valve other than that , its direct bolt on

 

[CanadianTSi]

I would think the Evo 3 Intake Manifold would be nearly the same as a 1G, which if just bolted on, as already stated would result in a loss of power.

Evo III manifold flows way better than a 1g specially if you have a PnP head.

Stage V port & polish head
Crower retainers & springs
1mm oversized valves
Evo III Intake manifold

This is my 2g head setup. This alone gave me about 45whp on a mustang dyno. I could of gain 60+whp with some good tuning. I was pretty happy with those numbers, gain a good amount.

I'd say a intake manifold would depend on the setup you have. I believe that my Evo 3 Intake manifold works great with my head setup so I don't need to upgrade to a SMIM. Plus is looks very stock.

Plus the Evo III Manifolds are very rare. I believe I'm the only one that has one in the bay area, I bought mine also through a DSM shop owner. He had it on his super fast 1g awd. Not even Ebay has it, do a search and only manifolds come up haha

now the question remains because you are the only one in this thread to have done it. Did you have to port your 2g head out to fit it like you would to fit a 1g intake manifold? If so the original poster would lose serious power from the ports being in different spots and angles.

Call up DEVO! Adam him self will tell you some evo III parts are better


I know for a fact the Cams,intake manifold, and a few other things flow a bit better

But for the Head, I dont know anything abou tthat

 

[staticbrainwash]

Though it may prove more losses than gains on a stock 2g head, how much modification would be needed on a 1g since they already have the larger runners?

I'm not trying to hack the thread, just asking so all the bases are covered.

 

[JOEY A]

I dont know about the diff in the heads, that im not sure on


But cams,manifolds, and a few other tid bits are better, I dont know about the head somone chime in on this

 

[JOEY A]

Anyone selling a EVOIII intake manifold?

Im looking to find one and have it Honed out

Post a Wanted Ad in the classifieds. No need to have this tech thread get cluttered up with classifieds talk.

I very curious. Did you do all the head work and the intake manifold at one time to achieve 40+ whp or did you Do the head work first and then threw on the intake manifold.

In other words, did the combo give you the power or did the manifold alone do it?

 

[DSMunknown]

One year later....


My guess is the combo. I would be very surprised (and very, very happy ) if it was the IM alone.

Motoman says that smaller intake ports are better.

Here read:

http://mototuneusa.com/think_fast_intake_porting.htm

Now argue amongst yourselves... he also says that port and polishing is an old school billy bob way of thinking... it's in there somewhere if you look for it.

 

[paper_clip_boy]

MotoMan is most like talking about NA Engines.

The principle in an NA engine is the the engine must TAKE/SUCK IN the air, thus in an NA engine VELOCITY is the objective. Smaller Port = Velocity, Smooth as a Baby's Ass Intake ports = Velocity.
Larger size will also help in an NA engine but in moderation, Im not talking about hogging out the whole.

Boosted Applications are the Reverse. Volume is the overall goal, although some polish is a good thing but again in Moderation. On the Intake side of things, Velocity will hurt overall Top end power. Perfect example is the 1G to 2G head comparison.

Less area to fill, the quicker the turbo will spool. Same size turbo with more area to fill will result in slower spool.

1G Head - Large ports, this will help in top end power.
2G Head - Smaller Ports, Will help with spool but Top end Power or pull will not be as good.
1G Cyclone - Smaller ports initially to help spool, boost start coming on, seconf runners are opened up to give a larger area to fill per engine revolution, more top end power with reduced spool time.

Ever Notice when you look at a ported head, the intake side is rough and the exhaust side is like a mirror? The reason for this is because we want that exhaust out of the cylinder as fast as possible. Also Turbo Cams are designed with a certain amount of overlap. Overlap is when both valves (intake/exhaust) are open at the same time. The reaon for this is because the incoming pressurized air pushes the exhaust out of the cylinder.

Best way I can explain it is the most detailed way. Able to visualize it?

The Evo3 intake runners are sized to a 2G head. The runners themselves are 3 inches shorter than a DSM intake and the plenum is matched to a 60mm TB like those on 1G's. There is no provision for an EGR or any other emissions related vacuum sources. Here is a pic of one on my car.

PS: 2G and Evo3 heads are indentical. The cams and manifolds were the difference.

I have a 1g and 2g head. The intakes are different not the exhaust ports. A 2g exhaust manifold is a direct bolt on and upgrade for a 1g. An Evo III exhaust manifold is an upgrade for a 1g or 2g. But I don't know about the intakes.

Have you actually measured the intake ports on the 2G head? In this post and this post, Siral3x believes the 2G head and Evo III head are in fact different. He does not, however, have any experience with 2Gs, which is why I expect you to know.

Do you also have an Evo III coil pack, or a modified 2G? What about the TB?

 

[sd_ff22]

hey Anthony,

forgot to tell you I have a stock 2g head in the garage!
I'll measure the ports before tonight to see the no BS answer.
the coil pack in the picture is an evo 2-3 Coil Pack.

I'll let you guys know.

Dan

I really wish my hdd hadn't crashed. I had side by side pics of both in which you could clearly see they were identical except for the EGR provision. That is not an Evo3 coil pack, it is an Evo3 bracket with my stock 2G coils. One interesting benefit of that was it swapped my firing order to match my 1G CAS, my wires go the properly labeled coil. The plenum is sized for a 60mm TB so I run a normal 1G TB.
