Take a close look at the photos below. These photos are specifically taken to show the shape of the ends of the runners. The end of the runners are completely flat for the last 2.5-2.75 inches before the air enters the head.

In this first photo you can see how short the runner is. Very comparable to the Evo III IM. As you have seen in a few of the above photos, runner #1 jets out quite a bit. You can see more of this below.

This next photo is very interesting. The Evo III runners do something similar, but certainly not as drastic nor in order. Also, the plenum throat measures 61mm (again, completely untouched), compared to the 60.5mm measurement taken on the Evo III IM.

And here is the Evo 8 TB. Notice that there are only two nipples on the top instead of the usual three.

The beginning of the TB measures at 67mm, while the rear of the TB (right at the mouth of the plenum) measures at roughly 60.5mm. I did a test-fit onto the Evo III IM and it bolted right up. I do not know if I will even be able to use this TB. A primitive search did not yield anything. It does look very similar to the NT TBs some DSMers utilize. The only thing I worry about is if the TPS and ISC sensors are able to be used/spliced into the DSM.

I don't plan on keeping the Evo 8 manifold around for too long. If anyone would like me to take any other measurements, just let me know. I'm not sure whether I'll be keeping the TB as well. If it serves me well to do so, then I will. If not, then it will leave the nest too.

I've noticed that runners 1 and 3 are a little offset from thoe other 2 on the evo3 IM. That evo8 IM looks very simmilar to the evo3. there are differences, but I can see the evolution(haha, joke!) of the design.

Makes me think of the thing going on right now about the SMIMs. that they dont work as good as the stock evo8,9 IM. but SMIMs showed a big gain on DSMs. so if I follow that means that by us replacing our IMs with the Evo3 Im we should be golden!

Not true. Marco showed a dyno graph of an EVO equipped with his manifold picking up power starting at 6000 rpms on a stock turbo. Spoolup looks to have been decreased by
200 rpms. Power gains on a DSM would be huge, which already has been proven time and time again. An EVO manifold would be a nice midrange compromise, but I'd take a short runner manifold if it was cast.
 
To attempt to give an answer to my TB questions in post #188, I posted up this.
 
Are there any advantages to using the Evo III coils besides that they bolt to the manifold?

Also, I am looking forward to when someone can produce solid before-and-after results on the 2g to Evo III intake swap. Perhaps the reverse could be tested.;):);)
 
No there is no benefit to the evo coilpack. iI just looks a lot better than trying to use your coilpack flipped over.

Not to mention that the evo coilpack is already wired to be in the right firing order facing coils out where as if you use your coil and flip it over you have to replace your wires backwards....

That sounds really confusing now that I read it...

cliff notes:
It is easier to use the evo 1-3 coil packs.

You do know that these only work with the 7bolt head right?
I just notice that your profile is for a 93.

Correct. I am just following the thread because of interest of knowledge, not so much for personal benefit. Plus, if it's good enough us 1g guys may convert to the 2g head/Evo III mani setup.:thumb:

That would probably be a wise swap anyhow, even without the EVO III mani. Of course there seems to be much debate regarding this, but IMO... the 2g head in combo with a 6 bolt block is the ideal pair to have.

Patience, little one, patience. It's in the works. ;)
 
Alright guys, if its in here, I must have missed it but for the guys that already have this mani installed are any using the factory 2g coils & if so what did you have to do to get them to fit? (not able to compare, to see what will work at this time) Also what are you running for plug wires? I'm running the Magnecors & it looks like they'll probably end up being abit too short for the new coil location on the plenum. It appears that the wores for a 1g may be abit longer & the solution?
 
I am using NGK wires and when I mocked them up to the location the evo3 coil pack will be in they seam to have enough length.
I've noticed something strange about my coil pack though. from the pictures that Anthony put up it looks like my coils are wired opposite his. meaning that his has the blue wires at the "top" of the pack, where mine has the red wires in this location.
strange.
also, I need to get a hold of a matching mount for my Ignitor.
Mine will be installed as soon as I can find a place to do a baseline run with AWD.

For the NGK wires, here are the lengths:

For the 1G:
Wire Length No. 1 419mm or 16.5 inches
Wire Length No. 2 579mm or 22.8 inches
Wire Length No. 3 719mm or 28.31 inches
Wire Length No. 4 659mm or 25.94 inches

For the 2G:
Wire Length No. 1 339mm or 13.35 inches
Wire Length No. 2 459mm or 18.07 inches
Wire Length No. 3 539mm or 21.22 inches
Wire Length No. 4 599mm or 23.58 inches

You can always make a custom set of wires and cut them to the length of your liking. It's not too difficult. ;)

The pictures I posted up sucked. I'll get some better ones up tomorrow.
 
Thanks for the input Anthony, so looks like if I'm short I can go with 1g wires. The Magnecors seem to be abit shorter then most other 2g wires, which is why I'm thinking I may be short. I really like these wires & just bought them last year so would like to stick to the brand. Not sure if they sell a "universal kit" to make your own custom length, I have done this before in the past but I prefer to buy a set thats already pre terminated from the factory.
 
Holy Hell Did I have a great valentines day!
Ok, where to begin!?
So I've been waiting to get a baseline dyno done so I can see what types of gains the evo3 intake manifold can give us right? Well I went to RRE last night to hit up their new dyno, and this was the first holy $hiter of the night. I walk around back to the dyno bay and they already have an evoX dynoing. yeah, came out 2 weeks ago and they are already working on parts for it. so that was cool.
comes time for me to get my runs in. and before I tell my story let me say that mike Welch is a very cool guy, but damn, he's like a devil on your shoulder!

So I started my runs at 15psi because that is what I usually run. I had been expecting 180hp and the first run came back at 178 so that was a good guess for me. We do another pull with more ducting to the side mount and I pull 183. Third run was 185!!
Ok, so I'm doing BETTER than I had expected already but here comes mike "hey, I bet you can get 190"
...
so I start upping the boost a little and get a little closer, like 187, 188.
He's completely joking, but here he comes again "you know I had a guy in here with all the same stuff and he couldn't do it, but I bet you can"

After a few runs to set the boost to 17 with out spiking too badly, I pull 190.3!
Every run was logged with narrow o2 and timing. During the "higher" boost runs we started seeing the timing get pulled a bit.
It doesn't sound like too big a hp number, but if our cars come stock with 210hp, think 25-30% parasitic drive train loss with AWD. So if I follow that number and put down 190 to the wheels, that could be 250-260hp flywheel! All mods are current in profile.
Another awesome thing is that there was no one scheduled after me, so I paid for 3 runs and ended up doing 13!

something wierd though. you always hear people say that the stock smic can handle(at low boost) even a 16g? Mike would hold his hand behind my side mount to see how much air was coming through, and he said out of nowhere it would get so hot he couldn't hold his hand near it!
hmm, my little t25 hits 190 and heat soaks an intercooler that "should" be able to handle the airflow and cooling easily?
Oh well. I'll put my FMIC in someday.
SO now that I have a baseline All that holding me back is wanting to make it EGR functional. I know Anthony, But I DO live in California. Oh and mike gave me an evo8s EGR valve to make a mount off of.

Oh and Anthony, While I was there I picked up and evos Throttle body. I was surprised by how light it was!

So, again RRE comes through and makes it a much better night than I thought It was going to be!

P.S.
Sorry, but I had to rant somewhere and I thought you guys would be interested:cool:
