Hi there! So I just bought a 2007 MDX intake manifold from a J37. From what I see - the locals prefer the TL SH-AWD one, but they're almost impossible to come by in my country, so I've sourced an MDX one. Is there actually a point in doing this, in a J32A2 application? Or is it a waste of money? I'm going to port the inlet (I am already running a Skunk2 70 mil throttle body), however I'm not sure what to do with the variable intake geometry butterfly - should I just leave it in place? And if so, how do I get it running? Is it a matter of extending the old connector, or is there trickery involved? I'd appreciate any input, I did try to do a forum-search (I'm not lazy when it comes to these things), to no avail. Thank you and cheers from the Eastern European block

And while I'm at it - here's my whip - a 2001 JDM Honda Inspire UA4. Swapped to a J32A2, with bored intake manifold, P2R thermal gasket, Skunk2 70 mm TB, 3-inch CAI w/ K&N filter, custom headers (DC-Sports replica), butterfly valve delete, full straight-pipe exhaust (stock diameter, same as the collector pipe that came with my old DC-Sports headers), EGR breather mod, DEC6 manual transmission, Honda Avancier Nouvelle Vague front struts to get the front end down after putting in the manual, Accord Euro-R CL7 front brakes, and a variety of polyurethane bushings all around the suspension.

Nice!

You from the Russian Federation?

Yeah man, Moscow. I grew up in America, on the East Coast, but I've been in Russia for the past 19 years.

To try and answer your question in regards to the J37 IM. I believe it is supposed to do a better job with flowing air and allow one to use a larger throttle body. The Intake runner manifold control valve is driven electronically versus the cable actuated one original to the vehicles IM.
I don't think I have seen anyone get it to work on the older vehicles.

6spd swap?

As for the J37 MDX manifold, it has more similarities with the J35A8. The manifold off the 3.7 TL/RL has a bigger inlet for the 80mm throttle body & flows even better than the previous manifolds.

As Zeta mentioned, haven't seen anyone with the early J series motors getting the IMRC to work properly.

InspireJ32A

Thanks for the input. So I guess I'll just rip it out, I had it deleted from the stock manifold anyway. The question is whether the older 17160RYEA00 is that much worse than the 17160RK2A00 one, but I guess that's something I won't find out then )) So I reckon it's impossible then to maybe install the cable-driven quadrant from the J32A2 IM onto the J37 one to get the butterfly to work?
The inlet on the IM I've bought is 68 mil or something along those lines, which is less than the 75 mil on the TL, but a quick bore should remedy that. I found a post about this on an 8th gen Accord forum.

InspireJ32A

Yup, it's a six-speed from a later model Acura TL. I used to have it on my J-swapped Prelude.
Speaking of J35A8 - is there a difference between the J35A8 manifold and the MDX J37 one? I'm guessing it's a tad larger in volume, but that's a wild guess with no evidence to back it up. Does the J35A8 manifold do the J32A2 any good at all, has anyone tried it out?

Well you can try. You'd be the first one on the forum to attempt it, if that's any consolation.

The thread below is the best one I could find, in regards to the subject; however, the pictures are all gone. You may have already read it, as well, during your research.

InspireJ32A

Yeah, I've stumbled upon this thread, as well as a 20-something page long topic called "possible new mod" or something like that.
Let me put it this way, will there be any harm from deleting the butterfly all together from the J37 IM? Just the same story as with the stock manifold, i.e. a loss in low end torque?
BTW, I've spoken to P2R about the butteflies - I'll just post a quote:
"In our experience, you gain throughout the whole RPM band with them removed. The only area that you lose is partial throttle at low rpm. But at wide open throttle even at low rpm you will gain."
But then again, they are running a race-car, maybe things work differently for their application,

I'll see if I can find some manifold info I read a while back.

Essentially, there isn't much difference between the J35A8/J37A1 manifold. They both flow the same, same inlet/TB size & both are 2 piece magnesium.

There is definitely higher volume in the TL/RL 3.7 manifolds & were designed to boost torque in the lower RPMs, with a working IMRC.

InspireJ32A

Well that sucks...)) Could've gotten the J35A8 manifold for a bit less money...)) Whatever, on the bright side, if they're pretty much the same - I might be able to fit my Skunk2 TB without any sort of adapter (the J32A2 throttle apparently bolts on to the J35A8 manifold).

InspireJ32A

Used the TL/RL manifolds are impossible to come by, unfortunately (where I'm from). I've seen people bring in 3.7-liter Honda Legends from Japan and part them out, but they sold the engines together with the manifolds, so I couldn't get my hands on one...( New is super-expensive, with the current dollar-ruble exchange rate and shipping fees. Literally more expensive than a complete motor for my car.

Sorry, the best I can say is 'probably'. I only say that because I disconnected my IRMC cable from the buttery-fly back in 2005, on my CLS6, when the supercharger was installed and did not notice a difference, other than the difference in power the S/C'er enhanced.
So the mechanism is still there it just does not actuate when called upon by the ECM.

InspireJ32A

Well, I'm just gonna find everything out for myself then)) Thanks for the info, I'm glad to see that people here seem to be pretty friendly and outgoing.

There won't be any harm but you'll definitely feel a low end loss. It'll only be beneficial to remove it if you can have the car tuned.

I recently did a J35 swap on a 05' TL I picked up. The J35 out of the Odyssey doesn't have an IMRC & even with the J35, it didn't feel right. I ended up swapping a J35A8 manifold off of my RL I had laying around with a functioning IMRC & the whole driving experience changed, put the power down so much better.

zeta

iTrader: (1)

You are welcome.

Just an FYI. If you can find a J35A3 from an '01-02 MDX over there that's not cost prohibitive, it should bolt up to your tranny. Then you won't have to worry about a loss in 'low end torque'.

InspireJ32A

TBH, I really don't know what it feels like to have a working IMRC. My Prelude had it stuck... Em... Opened or closed, which ever one of them is the optimal top end power position. And I removed the butterfly completely when putting the J32A2 into my current car. So I've no idea how the car should behave with the system fully functional.

InspireJ32A

Is there really a point in a complete J35A3 swap? If I remember correctly, they're rated at less than the J32A2, 240-ish or something like that. I dynoed my old motor from my Prelude at 291.6 at the crank with essentially just a set of headers and a 2.5 inch exhaust. The current motor is making closer to 300 (I guess), so no lack of power. And the torque seems pretty ok as well, actually.

zeta

iTrader: (1)

Oh, hell yeah! If I burn a hole in a piston during a hard second-third gear pull, (because it's not tuned with a standalone) I'm going straight to a J35A3. Drop on the heads from the J32A2 and have a J35 Type-S 6-speed.

teh CL

iTrader: (1)

Oh there's a point. The torque completely transform how the car performs.

InspireJ32A

We actually have a guy here who's done something like that. He put a J35 from a Honda Lagreat into an S2000, with J32A2 heads and cams, a J35A8 intake, and a lot of other stuff. He couldn't figure out why VTEC wasn't working for a while, the issue turned out to be the VTEC solenoid oil-pressure sensor. Before finding that out he had it on a dyno, 260 horsepower without VTEC, so such a hybrid motor is pretty potent))

InspireJ32A

Well... I guess it makes sense for city driving, but I usually wring the nuts off of my motor anyway...)

I hear you, so do I but I can vouch for the J35.. definitely doesn't stop pulling

InspireJ32A

Have you ever been to a dyno with yours?

BTW, how did you figure out I was from Russia? I'm guessing it has to do with all the "suka-blyat" dashcam videos and seeing familiar looking plates on some of my photos)

Never, the TL is a beater so I never bothered. Would be interesting to see if a cheap local dyno day pops up this summer.

Ahhh, my friend, by your own hand. It's there on your forum profile page for the world to see. Coupled with your excellent English, I figured go ahead and ask.

I like common Russian people, the heads of your government, not so much. Perhaps you feel the same? So, when the chance presents itself I like to talk, if possible.

InspireJ32A

Right, that makes a bit more sense...)) In terms of foreign politics, well... There are a lot of misconceptions as to what Russia's geopolitical goals are in the world, but admittedly there is a lot of stupidity (not malicious intent, but stupidity) on behalf of our government going on. As for what I peronally make of our government - I'm not particularly fond of our powers that be, mostly from a car-enthusiast's point of view, with all the speed-cameras being implemented, and massive crackdowns on the tuning scene. I mean if a cop wants to get on your case for a supposedly "illegal" mod - he can label it "design alteration" and nullify your registration. For example, if you have an aftermarket exhaust, even if it fully complies with noise regulations. Of course, there are a lot of loopholes (for example, they need to prove that it wasn't that way from the factory, which is nearly impossible when it comes to a Japanese car imported to Russia, which was officially never sold in the country: they'd need official documentation to verify the vehicle specification, which is almost impossible to come by). We obviously do our best to use the holes in our legal system, but the fact that they can give you a hard time if they wanted to is a bit unnerving. Thankfully, they usually don't care, until some high-ranking official tells the police force to start a crackdown.
In summary, no, I'm not fond of the government. I mean, they do what they should in terms of utilities, cleaning the roads from snow and what not, but lots of corruption and stupidy. However, from what I see on YouTube, things aren't that much different in the States, lots of interesting stuff going on there as well.

In terms of '...mostly from a car-enthusiast's point of view...' I can only tell you from my personal experience, in the form of 'harrasment', by the police, it does not even compare.

The worst I have experienced was in regards to the 'Move over' law here in Florida. This law requires you to Move Over a lane — when you can safely do so — for stopped law enforcement, emergency, sanitation, utility service vehicles and tow trucks or wreckers. If you can’t move over — or when on a two-lane road — slow to a speed that is 20 mph less than the posted speed limit. Slow down to 5 mph when the posted speed limit is 20 mph or less. Violating the Move Over law will result in a fine, fees, and points on your driving record.

Well, one day I was on a two lane 55 mph road coming up on three Sheriff vehicles pulled well off the shoulder while they were dealing with some other poor SOB. Anyways, I stayed at 55mph mind you in my 'Arrest me Red' CL-S6 and knew right away, from the looks on the Deputies faces, as I passed by, that I should of 'slowed down', LOL. So, as I drove on, I kept an eye on the rear view mirror, and sure enough, lights flashing and sirens ablaze, here came the po-po crawling up my a*s like a irritated internal haemorrhoid. Before I knew it they had me pulled over to the side of the road. So I sat there with my hands on the top of the steering wheel, wallet in hand, as this shaved head gung-ho deputy saunters up to my drivers window, juiced on noradrenaline, sweat running down his face. Give me your drivers license/insurance, now boy! I comply and he walks back to his car, breathing all heavy, like he just got done 'pumping the neighbor's cat'.

After about 10 minutes or so, he comes back, hands me my documents and asked why I did not slow down, yadah,yadah. So I stated, calmly, that since the deputies cars had been pulled well off the shoulder of the road, I did not think there was reason to, as I determined at the time, that no hazard presented itself, and just kept going. He then looks at my A-pillar gauge pod and asks, What's the gauges for boy! With a wry 'shit-eating grin' on his face. I calmly answered, there for 'fun' officer. He then states his last 'dig' at me and says, I better not catch you having any 'fun' on my roads, boy. Or all hell will bust loose for you! I said, you don't have to worry about me, sir. He states, get the hell outta here, boy. So, I fire up my car and move on down the road. Now, to say the least, I 'slow down' whenever I come up on any emergency vehicles responding to a call.

InspireJ32A

That's quite a vivid story) no, I've never had a cop go hard on me like that, although I've had a couple of situations when the cops supposedly "clocked" me at a speed I wasn't going. They'd actually shoot a radar-gun at someone else, and if that person didn't pull over for some reason - they'd keep that speed in the radar-gun's memory for the next poor bastard to come along. It happened a couple of times, and after a lot of arguing they let me off the hook both times (if you go to court, a radar-gun reading without video isn't viable proof of speeding).

You see, InspireJ32A, that's the kind of systemic douch bagery / fuckery the po-po here has a little more difficulty getting away with. Has it been attempted? Probably; however, it is not systemically inherent, get what I'm saying. With all the flaws the U.S. legal system has, because, after all it is manufactured by humans it is, 'more of less', just for the citizenry. For example, If I had my license or registration revoked/suspended, for whatever reason, there are 'set' state fee's and test's that I would have to pay/meet and then I would get my privileges back, end of story. However, the one thing I don't have to BATTLE is some 'corrupt' f*ckboy clerk/government official sitting at the desk, looking for a bribe in order to just get the process 'started'. Forgive me for my harshness, it is not directed at you but the system.

InspireJ32A

Nah, man, I read you loud and clear, no worries You're right on the mark about our system, corruption is indeed a harsh reality where I'm from. Mind you, it's not ALL bad, we do have plenty of clerks looking for a bribe, but it's definitely not that way with everyone. In short, Russia is livable, and a lot of things here actually seem to be better than in the States (any sort of IT services here are pretty well thought out and convenient). That said, I have a couple of friends who moved to the States a year and a half ago - and they don't really want to come back )))

InspireJ32A

It is very true that the system in Russia is organized in such a manner so that any normal citizen can be held accountable (for something, doesn't matter). So that when it is needed some strings can be pulled and, well, the governing powers can get whatever they need from any given person. Sometimes it really gets absurd, I mean, people have literally been thrown in jail here for reposting shit on social media))

Personally, InspireJ32, it just boggles my mind and is unconscionable to try and even begin to 'wrap my arms' around understanding that sad reality. That gives indicative proof to how different our two 'peoples/cultures' are and why we have the unfortunate 'state of relations' between our countries.

With that said, It has been interesting to talk with you and hear your perspective. You will find pretty much all of your questions about Acura's here answered in 'some form or another' over the years, it just takes alot of searching/reading, as you already know.

InspireJ32A

It's not that bad, as long as you keep a low profile and on the bright side - it does help with our sense of humor, A LOT)) In any case, there are people in other parts of the world living in hellish conditions (much worse than where I'm from, at least we have roads, food, heating, auto repair shops, 4G mobile internet and a certain level of prosperity in big cities), and they're still keeping their chins up
Thanks, appreciate the feedback! I'll put some photos up once I get this new IM installed (I'll hopefully try to slap it on during the weekend).
