If anyone out there has tried this; How hard is it to fit an EVO V Intercoler, and how much of a difference did it make?
 
Has anyone put a stock evo 8 fmic on their 2g? I found one local for $200 with only 500 miles on it, looks brand new. I'm curious on how well it fits and how much pipes would cost. I live in macon and there's no one around here that does custom intercooler pipes. Thanks.


P.S. is it even worth it?
 
sounds like a good plan, i would love to know if that would work, it also a pretty decent size intercooler.
 
From what iuve heard the evo 8 FMIC is pretty thin and has very few INNER fins, so it doesen dissipate heat as good..
 
200 is pretty good....its getting the rest of the piping fabricated that'll own your check book, but it'll still end up being cheaper than a greddy setup
 
well you could just buy some mandrel bends, its not a total PITA then, and NAPA sells couplers for not too much.. maby... 325-375 total assuming not TOO much 3rd party welding is involved
 
those things are trash trash trash. just like the starion and srt4.

ive noticed a trend lately from manufactures: put a fmic on the car and ricers rave about them and people eat them up.

the fmic is strictly a selling point. do your car a favor and dont put that shit on it.
 
is that why the norsk* designs evo ran high 11's with the stock turbo and intercooler as well as stock fuel system?

fuel system and turbo of use is irrelevant. exceptions to the rules are pointless. phil beers is .05 away from making the same claim with a stock 1g smic. i guess you can put the evo8 fmic and 1g smic in the 11 sec intercooler group then.

like leet said, theyre shit. im gonna go out on a limb here and say it was pruven that tested theirs about half a year ago only to laugh at it.
 
well the evo 8 ic might be "junk" but the starion is also called "junk" and i think the evo has bigger pipe inlets and outlets?? i'm not sure but for 200 grab it and if u can't do anything w/ it the civic kids will eat it up on ebay, however it does handle 275 stock HP and the starion handles liek what 190-180 hp stock? so i'd pick up the evo myself. good luck

$200 is a good deal, but you can find a lot better cores for just a little more. I have seen spearco cores on ebay for like $300-400 and street imports fmic (i have one on) for about the same, if not less. Save a little more and get a decent FMIC, you dont have to dump out a bunch of cash and go with a Greddy or Apexi, or similar.
 
exactly it's definatly worth picking up for 200 selling it will probably pay for a good fmic like a griffin or something (i'm not to keen on FMIc pprices or whats a good one and what isn't). good luck

Just completed installing an EVO III 16G, RNR O2 Elim. exhaust, FMIC, and all is well. No boost creep either thanks to removing most of the wall between the waste gate and turbo outlets on the turbo exhaust housing. Full boost by 3300 rpm (15 psig), and rock steady all the way to redline. Car is running great and hasn't even been tuned yet. Many thanks to this website and it's users. Couldn't have done it without you. :thumb:
 
congrats on the successful install. how bad is wheel spin with FWD. i am debating between 16g and 20g. there is only a 50$ difference. let us know when you get it to the track. :thumb:

Removing the wall between the wastegate and the turbine outlets works to eliminate boost creep because it kills the turbine's flow, not because you increased wastegate flow. Most turbocharger books tell you to keep the two streams apart for as long as possible for the best efficiency.

Then why are some turbos designed that way?

Because it is cheaper? Packaging reasons? Who knows. But it is a bad design. Yes, the PTE turbos that have that wall machined away are a bad design. It is a hack to get rid of boost creep.

Also how would it kill flow, it's after the exhaust gases have already gone through the turbine wheel? It might even increase flow because of less restriction.

It won't increase flow, sorry. The flow of exhaust gasses out of a turbine is nice and smooth. But the wastegate dumping into the turbine exit disrupts the smooth flow.

Think of it in terms of a highway. You have a highway packed full of cars, but flowing along at 65mph. But up ahead is an on-ramp. And those cars need to get onto the highway, so they just start merging in. So the traffic on the highway has to slow down. But the highway traffic doesn't just slow down AFTER the on-ramp, it has to slow down before the on-ramp, too because of the extra volume of cars on the highway up ahead.

I thought about adding a toll booth as a turbine, but the analogy started going bad.

You want the on ramp to be where the car volume is the least.

As exhaust gas cools, the volume of the exhaust goes down, and the molecules bounce around less as they travel. The smaller space between molecules means that a given cross-sectional area can carry more exhaust molecules. Ideally, you wouldn't want the wastegate gasses to merge back in at all, but to cause the least disruption to the turbine flow, try to get the wastegate merge point as far away from the turbine as possible. But cutting the wall out between the wastegate and the turbine exit puts it just about as CLOSE as possible to the turbine. Bad news.

You asked me earlier "Then why are some turbos designed that way?"

I could have just as easily asked you "why do you think that wall is there on Mitsubishi turbochargers?" Give it some thought.
 
Apparently the wall is there to cause boost creep, because that's what it does. There must be some kind of flaw in that design also, because of creep problems that it causes. You can eliminate creep some other ways with internal waste gated turbos, but they all increase waste gate flow into the exhaust system in some way. I must be getting pretty good flow if I'm reaching full boost by 3300 rpm without even having tuned the car yet.
 
I have zero boost creep with my car with a larger 2.5" tubular O2 housing on it. And my Evo III 16G isn't ported at all.

It is currently the fastest and quickest Evo III 16G on a DSM.

Sorry you didn't like what I said, but it is true.
