Those #'s sound about right. I'll be doing the rbc swap maybe this summer. Bad news with Flashpro - does not support the 2014 ilx yet. Doug at Hondata said he'll fix this week, so i will be waiting a few more days for the tune

aomechmarine

damn that sux… its all good tho, waiting on other parts development, and it's not like most of us have the cash to just tune our car "overnight" anyway. Its more of a long, fun, ongoing process throughout ownership right?

OSUBeaver

Exactly, almost never ending. Every time I say "this will complete this car" I find myself scouring 9th gen forums for more ideas.

Oh yeah as for the TB spacer, a lot of mixed reviews out there. I'm not convinced it will add any horsepower on my set up. Once the RBC goes on I'll do a big bore TB with a built in spacer and switch to a true CAI.

With new injectors we should be sitting somewhere between 205-220hp at wheels. I'd be very pleased with that

Triscuit

What are the offset specs of your wheels? Running a 15mm spacer and a 19mm spacer makes it look flush. I like it a lot!

OSUBeaver

They are pretty solid. Could have stretched 18/23 (approx) but oh well
believe they are +45.

OSUBeaver

Newest Beta version of Flashpro does not support the 2014 ILX 2.4L at this point. I was hoping Hondata would get it fixed asap but they said it will be fixed during the next release in April - Just an FYI if anyone is considering buying one soon

usdmJON

Wouldnt the 2.4 civic si be the same thing?

OSUBeaver

You would think so - the code on the ECU is different for every make/model and year. Every specific code has to be programmed in the Flashpro before you can use....and in this case it was not

usdmJON

So any updates on the exhaust? You liking it?

Im still looking at a rear section of 2.25 Not much else is made for the r18.
My downpipe is already 2.25 as well.

In the future I am going to put some 2.5 mid section piping in and if I can find a downpipe that is 2.5 Ill jump on it.

As for the rear, I dont need anything over 2.25. My integra had a huge exhaust and I dont want to get that look on my ILX.

OSUBeaver

The Ultra Quiet Resonator coupled with the Hushmat in the trunk did help quite a bit. But overall still too loud. I will be replacing the actual muffler here in a month or so. Working on getting the exhaust tip to show from the rear now. Cutting the bumper up in a few weeks,

usdmJON

Nice. Cant wait to see it.

Im ordering up my exhaust here in the next few days... maybe today.
Im relatively confident the exhaust will fit but be rubbing on the button of the bumper. So some extended hangers should clear it no problem. Just a matter of if it looks funny.

OSUBeaver

Thought I'd share this with everyone - After almost 2,500 miles the 2.4L is averaging right around 30MPG. I've done the actual math by hand 3-4 times and was just over 30 each time. No bad considering Acura claims the 2.4L gets 31mpg highway! I'm about 75% Highway

Flightwriter

Nice! I've also found my 2.0L/Auto to be acceptably close to the EPA highway estimate, according to both the trip computer (surprisingly accurate, in my experience) and my own calculations. My city MPGs are a few shy of the EPA rating.

usdmJON

on what octane gas?

Flightwriter

Premium (91 octane, and sadly with ethanol) for mine.

OSUBeaver

I use 92 Octane out here in OR

same - w/Ethanol

aomechmarine

Damn - I will be super happy to see those MPG numbers once I get my exhaust, intake and maybe a downpipe. I'm gonna pass on the RBC swap… Right now my MPG numbers are consistently 27.6, a lot of city tho. And it gets a little better 28.5 when i take the 2 hour drive to San Diego, but there is a lot of hills on the way, and i drive 80mph 80-90% of the way (if its empty I might drive 90ish, over 100mph is a felony). I never use cruise control. I think if I was driving conservatively, I might get better but, meh…. How 'bout anybody else?

aomechmarine

Not proud to admit this because it was really stupid, but when I had my 2001 civic em2, on IHE, with brian crower cam shafts, It was lowered on tein, all kinds of suspension bars, and performance wheels and tires I once hit 150 mph on the freeway. I made the 2 hour drive in just over an hour. I could literally see my gas gauge going down, my foot was mashed to the floor, and it took FOREVER to get up to that speed. From 60 to 120, not too bad, 120 to 135 140 slow, 140-150 super slow climb. Anyway, I wrecked that car later on, on the street. I wasn't even driving crazy and it happened like a 3 minute drive off base, and that car was DONE. I learned my lesson. I'm just very lucky I didn't kill myself or hurt other people. I'm not gonna lie tho, it was an incredible rush. It was like a wednesday morning at like 2-3am. That car only had like 135whp too. Before you judge me, I had just got back from deployment. Ask around, car wrecks, speeding, DUI's, getting into fights with people, and just bad news and acting out often happens when we come back.

aomechmarine

still passed smog too. And I was getting 35 mpg all day. except when I would drive like a dumbass.

usdmJON

Yeah I see more like 25mpg average. Pretty much nothing but city driving. Everyday before work is 15 minutes of city driving and 5 freeway.

OSUBeaver

Getting some extra cash here in a few weeks. Already made some appts and dialing down pricing but here's what's on the docket for April and May:

Slotted and Dimpled Rotors (just for looks)
Cutting the Bumper for the Exhaust Tip
More Clear Bra on the roof, trunk, Gas tank Door
Full RBC swap - PRL CAI, Big Bore TB, Injectors, ETC
Already paid for Flashpro+Dyno Tuning but will do that after the swap - no reason to do it twice.
Lower Tie Rods
Rear Sway Bar

usdmJON

Fuck yeah. Wish I lived around Oregon to see her rolling.

I have so many friends that want to live there. hahaha Portland seems to be some fort of retreat for retired california Gen Yers.

OSUBeaver

Where the young people come retire buddy

usdmJON

hahaha Seems like a fun place to live. My friend says I would love it. My ex moved there for school and Im pretty sure she plans on staying. Another girl friend of mine went to visit not long ago and she loved it. She showed me the show Portlandia when she got back and said its literally California in the 90s... kinda sparked my interest. lol The 90s were fun.

aomechmarine

Damn I guess youre getting a good price for your RBC swap. Plus you don't have to deal with smog… think it makes sense for you over a supercharger.

OSUBeaver

Not sure how people are seeing prices for a full RBC kit (PRL CAI, Injectors, Battery relo, etc) that are THAT much different than what I'm getting. No special discounts/rebates and I can find the whole shabang for just over $1200. Can install myself if necessary. CT SC costs a little over $4,000 with no rebates/discounts. That's over 3x more $$.

Here's a link http://stores.axionind.com/2012-hond...-kit-race-cai/

I'll even tack on another $400 for some other parts/upgrades and your still well under $2000 for the entire kit. My budget for the kit is $2000 and I can not only do that but add on a couple of upgrades (better injectors, TB or TB Spacer, etc)

aomechmarine

Yeah there is different "levels" of the RBC swap. I was specifically talking about the most power producing version. To produce the most power from the RBC, you have to get the biggest injectors, which requires machining to work. You also have to switch to E85, which obviously requires using Hondata Flashpro (I'm going off of what was done to the axion industries 2012 civic SI). So; injectors, machining, E85 swap, flashpro, and a couple smaller things too ($$$). You will make more power with the RBC, but I was specifically talking about the Cali carb legal supercharger vs that top level RBC setup, as they produce similar power output. Since you're doing the solid basic RBC swap, it's less involved then this crazier setup. The supercharger will still put out more power then your setup, and way more if you don't set it up to pass CARB, which would be of no concern to someone that doesn't live in California. In the end it's pay more get more

aomechmarine

You already bought Flashpro so you weren't including that in your price. So basically add your $2000 RBC + flashpro ($800) + machining($200) + E85 swap ($500) + labor (??? could do yourself if mechanic). Anyway numbers are rounded for simplicity. Lets say it is $3500 flat tho. In California, its all illegal. $3500 illegal setup that ALL has to be reversed (to pass smog) VS. a $4500 legal setup that is "set it and forget it" - does not ever have to be reversed, AND produces more power. Unless you are doing the work yourself, (the highest trim) RBC will be a much more expensive setup to have in the long run (in California). And even if you do the labor yourself (setup and reversal, and then reinstall), think of the time that eats out of your life. For you - great - set and forget. Cali residents - HELLLLLL NAH! Maybe the setup you're getting is worth it tho for some in Cali. It's a significant power gain, but not as much reverse work involved, as well as no machining involved (right?). And like you said - 1/3 of the price of the supercharger. Sorry for the long explanation and threadjack. Just trying to fully explain. Anybody else's thoughts?

OSUBeaver

Yeah I agree - I would definitely go with the SC if I lived down there.

As far as the Flashpro goes - you're going to need one of those with just about any set up so I didn't include the price.

Will be pulling the trigger as soon as Hondata's next beta release. Here's the final cost break down with upgrades/details.


Manifold - $220
ZDX Throttle Body Adapter (no charge)
ZDX Throttle Body - $220
Port Matched for 70mm ZDX Throttle Body - $100
RDX 410cc Injectors Plug n Play - $220 (stock are 310cc)
PRL CAI with Battery Relo Kit - $350

That's only $1,125 with the larger injectors/Throttle Body/CAI - no other machining necessary. I think this kit used to require machining for injectors such as the RDX 410cc but not anymore.

That's just not a bad price point at all, if Hondata had already released the next beta I would already have installed this. Not very patient with these sorts of things!

aomechmarine

Man once you throw on the RBC - I think its not reaching too far to say that you will have the most powerful ILX on the street (that we know of). And the only truely "tuned" one. Can't wait to see dyno numbers. Does acurazine have a page for that (WHP leaders)? I'll dig around, I only really check out the ILX section. Sometimes I'll look up random stuff tho. Anyway, pretty sure you will be number 1 on that board.

OSUBeaver

Maybe, gotta think someone out there has thrown on a CT-E Supercharger but not in this forum. Only thing I'm worried about is the downpipe sizing I chose to put on - 2.5". Vit has told me a couple times the K series reacts really well to 3" exhaust systems. If I do everything and I don't break 210hp then I think I'll have to consider forking out some more cash. At least someone on here can get a very slightly used RV6 Catted Downpipe for a bargain....

9th Gen Forum has plenty of guys with the EXACT set up (but with 3" pipes) getting 215hp-225hp. I'll keep people posted - these are the things I wish I knew before hand. I didn't think the 3" would add much (If anything) w/o a SC or turbo set-up. We'll see

OSUBeaver

RBC install with dyno tune happening on May 3rd. All in cost about $1350 with install costs (Vit).

Will post dyno charts, pics, reviews when done. Weekend after that will be cutting the bumper for the exhaust tip.

Cheers

usdmJON

Yesssss. Can't wait. Want to see shots of the bay and a video.

OSUBeaver

Well the RBC set-up may not happen now. I've heard chatter on the 9th gen forums about losing mid range TQ with it but never saw a dyno to prove/disprove. Vit just sent me this:

OSUBeaver

Might just do the dyno tune and start saving for the SC. Could buy it now but can't really afford to Re-Do the entire exhaust/downpipe set-up I just put money into

OSUBeaver

For anyone that has thought of the RBC set-up - here's some background/info from my 9th gen post

Sorry for the long email here man but here’s what I got:

Link below is the Dyno that stopped me in my tracks. A little background on it: This was the 1st and only real dyno (non-edyno) That Vit has ever seen truly comparing the Stock IM to the RBC IM. The comparison was done on the same day, same dyno, same car with both tuned (by vit I believe) for optimal power. Again, this isn’t coming from someone who doesn’t enjoy making $$$ off RBC re-tunes and installs so there shouldn’t be a hidden agenda here. He said there are A LOT of guys claiming 220-230whp with the RBC set-up but in almost every case it’s either an e-dyno or an infamous high-reading dyno. And in every case no one did a dyno before and after (with a full tune) showing the gains from just the RBC. This is the only one we know of. To be honest I always thought it sounded too good to be true, 37% whp gain from a few bolt-ons, RBC IM and a tune? Seems really high to me. Vit showed me a couple recent 9th gen dynos with full bolt-ons (minus the RBC) and whp was about 190-195. 20-40hp gain with the RBC seems crazy when you consider a stage 1 SC gives you a little more for 3x as much $$. Just my thoughts. Notice only peak peak HP saw gains with the RBC and the massive TQ dif from 3000-4800 rpms (which is were a lot of us do most of our driving)

I believe Slaamed ILX is going to be doing an RBC swap... first to do it? That kid is vague about stuff. I just got a free cold air intake. First 500 miles or so I'd say my MPG went up, from 27.6 to almost 30 mpg. However, at some point, I believe the computer adapted, and fought and adjusted for these MPG gains. In fact, they are now slightly down ( I was driving kind of fast on long highway trips). I believe with a tune, this would change a lot of things. The cold air sounds great (personal preference) because it is not too loud and can be easily heard at WOT, however, is not super loud. I did however notice a power gain. It is only noticeable to me at WOT or by buttdyno. Basically just climbs RPM's quicker. Nothing crazy. I am eager to get my free exhaust soon and see how they work in conjunction. Gotta say, I believe the RBC stuff you are saying man. I think its one of those hyped up gains. Most of the cars seeing all those "gains" had all other supporting mods available/ possible. Basically - its not JUST the RBC making all that power. Its why I am talking about the cold air. I think people get butthurt they spent money on parts that don't necessarily deliver on what all was promised, and they don't/won't admit it. I DO believe there is definite gains, just not as much as "advertised" purely on the RBC by itself.

OSUBeaver

The question is does the rbc set-up kill midrange TQ as much as it looks. Top end horsepower does not justify losing that much mid range. I would tell anyone looking at doing the RBC swap to ask yourself in what rpm range do you do most of your driving. For me it's exactly where that loss is coming from. Even if I gained 15 hp at the highest RPM range and lost 5 ft lbs of TQ in the mid range it still wouldn't be worth it to me

aomechmarine

I get what you are saying. I mean most people are not WOT all day. i think midrange is where its at for most.

OSUBeaver

Just got back from a 3 hour dyno session with vit. Baseline whp is 165ish on a bone stock 2.4l. Before tuning I was at 177whp. After tuning 191whp and 165 ft lbs. stock torque at the wheels is low 150's.

Rev hang gone, throttle response much much better. Best mod so far.
