They aren't all bad.......
 

Hello members. I am brand new to evolutionm, but I am not a noob with cars, aftermarket parts, and racing(two season championships in SCCA). Let me establish a few things right off the bat:
I will not be some another annoying moron who trolls around asking what’s the best part for ‘X’ application, or what’s your favorite catback. I may ask based only on performance numbers, because that’s the #1 thing on my list, performance. All go. I have been reading every thread possible on this site, because as a longtime car forum member at many different sites, I know how annoying it is to have people asking the same damn questions all the time. I will be purchasing an EVO IX, but have not decided between the RS and the MR. I have decided on my first round of mods to go with my first ECU reflash. They are as follows, and I have a couple initial questions to go along with the list. Any and all information will be greatly appreciated!

- Forge UNOS MBC (unless someone can sell me on an EBC that’s going to be a better overall value)
- TBE (I have initially begun to lean towards Buschur, but I have also read that the IX’s may have slight fitment issues while using the VIII’s exhaust systems. Of course, I won’t be getting my IX for a little while, so my options may open up before then.)
- Boost gauge (obviously)
- Walbro 255 (I have heard contradictory ideas about this, but the popular idea seems to be that I will not need a FPR or any other mod(lines) for the fuel system on the IX…..if someone could confirm….)
- ECU reflash. I’m undecided on who to send it to though. DynoFlash and Ecutek seem to be my two options as of now. Obviuosly, the mods for my first flash would be TBE, MBC, BOV, walbro, intake, and cams. I was wondering about the PSI that the reflash will use. I have read that the highest the IX’s BOV can take is about 21-22 PSI. With the upgrade to the Forge BOV, will there be anything else I’ll need to run 23-24 psi safely?
- Forge RS BOV (seems to be the way to go if I want to get my reflash set for over 21 PSI…not to mention that I’ll be running 93 octane all the time. 24/7/365….any info would be appreciated.)
- Cams. I’m totally undecided on the brand and the specs. The HKS 272’s look like they are the most popular, but I’ve also seen setups using 264 intake and 272 exhaust cams. Why? I am also hesitant about their ‘lopey’ idle. I would assume that the 280’s are clearly not very streetable….. confirm/deny? I would obviously want to go with maximum power, but as I won’t be racing the IX, I’ll go with comfort…a little. I don’t want my first post to have a “which brand is best” but which one has the best power yield?(HKS, Crower, GSC, BuddyClub, Invidia, ect.) Also, to go with the cams, what are the recommendations for replacing the head studs and/or the headgasket?
- I think that with the added torque, I’ll need a new clutch before too long, but I’m not sure if Mitsu changed the clutch/flywheel setup for the IX. At this point, I think I should wait to get the Exedy twin puck and lightweight flywheel until I research more and see some results from current IX owners. (I assume that’s the best clutch for my application…)
- Final thing: What is everyone’s ideas on an air intake? I have read many contradictory opinions on this. Would the $ spent be worth the extra top end power? Would the drain on low end power be worth it, for a vehicle that will primairly be a daily driver...? I would like to get a little extra out of this first round of mods, and would of course include the intake with instructions for my reflash. This is where I need the most help I suppose, with a freaking intake. Lol
- I will not be racing this vehicle. It’s just to be my daily driver. I’ll be racing an EF Civic in ’06 and ’07. Thanks for all the help, my experience with the VIII was strictly in stock classes in SCCA.

Thanks in advance to anyone and everyone who posts to say hi or to help me out. :beer:

What up.

Nada. You? :D

First welcome to the forum, and good luck on choosing on the RS or MR. Now, you can't get CAMS for the IX yet, you can only change the exhaust cam but not the intake cam (for now) because of the MIVEC system. The headgasket will be fine for the mods you are going for along with the flash. The headstuds are will also be ok, but if you want some added security, go with ARP. For the "BOV" you don't have to change the stock one because it is now a metal piece (JDM MR valve) and not a gimpy plastic one.

Thanks for the reply. :beer:

1. Did not know that about the cams, thanks.
2. ARP are the only headstuds that I'd consider.
3. I know that the IX is using a metal piece for the 'bov' valve, but per my first post, I think I should upgrade because I've read that it will not hold much more than 21 psi, and my initial goal is to go 23 or 24 psi. Please advise on the Forge based on my first post, and performance needs.

My question is...where have you read most of this false info regarding the following points:

1) Walbro - there aren't contradictory ideas, unless you mean 1 out of 100. You don't need to upgrade any other fuel-related items when running this. You also don't even need to upgrade it on the IX with pump gas on the stock turbo. It's an upgraded unit over the 8s.

2) Cams - man, come on, you have to know there are no cams for the IX yet. All it takes is a brief, quick search on here to see that the MIVEC makes it where you can't use the same cams (only the exhaust has been tried, but no gains have been seen).

3) BOV - where did you hear that it can only hold 21-22psi? We consistently say that it's good for up to 24-25psi. I personally went 12.000 on race gas pushing 24-25psi on mine in an 05 with stock cams. I upgraded to the Forge RS, because I now have alky and push anywhere from 26-28psi on a daily basis. Your stocker will be 100% sufficient on pump gas boost levels.

4) Intake? Blah, all those questions are just overboard. It's just an intake...it's not needed. We've discussed this thousands of times. Get one only if you care about sound and don't care much about your finances. The stock airbox is very good, because it sucks in only cold air from outside the engine bay, keeps a vaccuum seal, allows for non-turbulent airflow across the MAF, keeps noises to a minimum, and is not a restriction before 400whp.

5) The difference between an EcuTek (can get from Dynoflash and many other vendors) and a Dynoflash (techtom software) is anywhere from $200-400 depending on whether you get a custom Dynoflash or mail-in Dynoflash. The features are the same but with the Dynoflash having one extra: removal of fuel cut.

In conclusion, as I've already said many times, all you need are the 3 basics:

TBE, MBC, Dynoflash = 330whp = 12.0s on 93oct = <$1000

What a surprise post coming from you dude. :lol:


1. So you're saying that for 350whp/350wtq (give or take 10hp/tq either way) that the stock fuel pump is fine? As for where I got my contradictory information, I have only this site to reference. Sadly, your posts aren't the only ones I've read, Warr. ;) I read on here that the IX accepted the Walbro easier than the VIII, and didn't need some of the 'kit' that's needed on the VIII.

2. I don't have to know anything. There are many threads on this site discussing cams, and few of them mention anything about them in relation to the IX. That being said, I'll research the cam issue more, and post what I read. Keep in mind, these are not my ideas and opinions, they are 3rd hand information I got oof on an internet forum. Namely, this one.

3. BOV- again, on this site is where I read that the IX bov is good up to 21-22 psi. So you're telling me that it's safe to run up to 25 psi? Of is that not a safe 93 octane psi level?

4. I have read your opinions on the intake, and actually the question was to gather multiple member's opinions and impressions. I even agreed with you in another thread where some genius said that warmer air doesn't effect power. (lol)

5. To get a custom dyno flash, I'd need to live somewhere near a dyno, or go to one. Anything close to Charlotte? I haven't heard of anything closer than Atlanta.
What difference does the fuel cut make other than being able to go a higher top speed?

What are you basing your information for the IX on, Warr? I know you don't have one....... just trying to clarify, not starting rifts.

Also, say I wanted to step the TBE+MBC+flash to make more power on a IX without getting too crazy. What would you recommend after those big 3 mods you're always talking about?

Thanks.

*edit*- Where can I get a TBE for less than $700? Because if the flash is going to cost at least $250, and the MBC is what, a minumum of $50? I see you run the Megan one. Based on my Nissan experience with Megan, I would stay the hell away, but they seem to make ok stuff for the EVO. As posetd, I was leaning towards Buschur, as it seems to yield the most power. Thanks man.

Warr has the megan tbe exhaust and has some pretty amazing times for his mods so don't descredit megan.

If your on a budget get a stewart warner boost gauge with an autometer column mount, megan tbe exhaust, forge unos mbc, and buschur intake with a dynoflash mail in.

A recent member on evom.net down in FL ran a 12.XX @ 112 on PUMP gas with tbe exhaust, mbc, mail-in flash so the potential is there, be sure to check out the drag racing forum for more info and a vid.

(A mail in flash is when you take out your ecu send it to a tuner and he then flashes it for you based on what mods you have and then mails it back to you compared to a custom flash which is done on a dyno or the street)

I know what a mail in flash is. lol As I said, I'm not a noob to cars, brosepf. ;)
I also have been in the drag section a lot, but again, my car will not be raced. Not on the strip, not on the track, not on the street. I don't need 7000 rpm dumps ruining my clutch! I also know that Warr has the Megan TBE, I see it in his sig, and I posted that I knew he had it in my last post on this thread.
I'm not specifically on a budget, I was just questioning the < $1000 set of three mods that Warr talks about. And no doubt he runs great times.
My major questions are:

Is the Bushur exhaust the one that sees the most gains? Not just peak, but whole powerband?
Also, you mentioned to get the Buschur intake. Warr is adamant that it's not needed until 400whp. What is your opinion on the intake? Is is worth the $? Seems not to me......

I think most 3in TBE are nearly the same as far power gains, They all sound a little different depending on the exhaust but, it's not rocket science. You'r right about the intake, just get a drop-in, and there are hundred "cams for the IX?" threads

Be sure to hear any exhaust before you buy it because they all sound different. I personally would not buy the BR TBE because is loud and I am not a fan of its tone but then again I have not heard the revised BR tbe exhuast yet.

I would go to a local evo meet and hear the different exhausts and then buy what you liked most. Any 3 inch catback with no neckdowns and minimal bends will produce about all the same power, just be SURE it doesn't taper. Check out dynoflash's beer can test regarding exhausts.

Stock airbox works fine like Warr said but the BR intake is $80 bucks so you can't complain.

(Sorry about the mail-in-flash thing just being 100% sure you never know with evom{thumbup} )

The Buschur TBE is a great unit, but there's no proof that it makes more power than the MEgan or any other 3" pipe. It is designed to be very straight, it is PROVEN to be very light and PROVEn to always make great power, but trying to choose an exhaust based off which one makes the most power is mostly fruitless. Base it off which one fits, has a good value, is light, sounds ok to you, and looks ok to you. I always say to get the Megan first, but since it's not 100% certain that it will fit your IX, my top suggestion is Buschur. With the Buschur TBE, Forge UNOS MBC, pod+gauge, and mail-in flash, that would be like $1250. For a Megan+UNOS+Dynoflash+gauge/pod, it would be $985 with a little extra for shipping maybe (included on the Megan price from Zeus).


1) "I read on here that the IX accepted the Walbro easier than the VIII, and didn't need some of the 'kit' that's needed on the VIII" I don't know where all this crazy info is coming from - this is what is scaring me. Maybe I'm missing these strange posts somehow? The VIII doesn't need a kit either. The Walbro 255 fits right in with no extra parts and no hassle other than getting the retaining ring out, since it's about the same size as the opening. That's unrelated to the FP itself.

2) The last month or so has been full of threads talking about cams in IXs. We've had multiple tests to include a regular IX street car and a IX with stroker who both used the same exhaust cam. Regardless of testing or not, the fact that cams aren't available for the IX has been said countless times.

3) You keep saying you've read this stuff on the site, but I don't know where you're reading it or who is saying it. If I could find these inaccurate posts, I would respond and refute them. Like the fuel pump, maybe 1 in 100 people would say the JDM MR DV can only hold 21-22psi, but the vast majority of us know and state otherwise. However, don't mistake what the BOV can hold for what's safe to run on pump gas. Those are 2 completely unrelated aspects of boost. You shouldn't run more than 22psi on 93oct, and maybe even lower depending on your other mods. The stock IX DV will hold all the boost you can run on pump gas, but that doesn't mean you can run 25psi without damaging your engine...

5) I don't know why you think you'd need to live near a dyno or whatever. Al travels all over the country doing custom road tunes. A dyno is never needed, and frankly he prefers NOT to tune on a dyno - he prefers true road conditions. To answer your question, he has tuning trips to Atlanta, Raleigh, and Charleston (SC) coming up in the next 2 months. You can also just get a mail-in flash if 12.0s on pump are ok with you, but of course you won't even be racing the thing, so I don't know why I bother. I'm not sure why you think we are all out here doing 7k clutch dumps...it would be dumb to do that. Plus, that wouldn't hurt your clutch anyway, it would damage the drivetrain. You can launch right off the 5k limiter all day. If you don't ever launch, then you're not even making use of your biggest asset - AWD.

If you'll run a search using " cams IX " you'll see what I meant. Thanks for the info though.

As for the exhausts running the same power, I saw a thread by David Baschur when he had an EVO with some aftermarket exhaust parts that were his, and some were not. He changed the ones that were not his to the ones that were, and experienced more gains. Yes, I know that he went catless and ran with different psi settings, but I was overall convinced that his products are very quality. And agian, I have had some horrible personal experiences with Megan.

Thanks again man. I honestly like loud exhausts, but I honestly don't care too much about loudness or tone. May seem strange, but I like power, power, power. If there's really no difference, then I guess I'll go with the cheapest one, which seems to be Megan!
Damn, only $80 for the BR intake? That makes it more tempting. Warr, would you say that it might be a good investment? :D

Well, for whatever reason, no one can figure out the basic search features I guess. The very first time I tried to search for "cams IX" in the advanced search looking for topics with those words, I got 6 threads:

https://www.evolutionm.net/forums/se...archid=1994849

Then, when I did the same search with "cam ix," I got 3more, one of which is someone who tried the exhaust cam in his IX but with no noticable gains (in my opinion):
