You don't need the EGR pipe. Mine didn't even fit. ILC did yours? I doubt that's why my CEL pops every 200 miles.

EGR pipe not needed.

I've put several hundred miles on the car with no CEL.

Can anyone confirm what size silicone coupler/reducer I need to mate the AEM V1 to the ZDX TB?

I measured the OD on the inlet of the ZDX TB and came up with a hair over 3.25", so 3.25 will work on that end. I looked under my hood and the reducer on there now steps down slightly from the intake to the stock TB. I'm guessing it's a 3.25-3.00".

I'm thinking I need a straight 3.25-3.25"??

WTH?! Wish i knew that sooner.....LOL. Also I'm going to have to break down and get another CAI. My present intake don't have the bung to relocate the IAT.

Sonnick

I have the V1 as well and it fits fine with my 3" to 3" reducer. My buddy just heated up one side and stretched it over the TL throttle body. The V1 is 3" OD, like 2.75 ID.

That bung is a pain to find. I've been searching for some time now and haven't found one.

yeah i didn't transfer any of that stuff over. Just bought the 3.7 manifold and plopped it in and it worked just fine, lol. I also just passed emissions the other day.

t0talacuratl

iTrader: (3)

so you didn't plug your IAT anywhere? I guess the 04-06 would get a CEL for not having the IAT screwed in. I got one when I over tighten it and had a slight leak.

anx1300c

iTrader: (2)

I measured the circumference on the AEM and got 10.25 which comes out to 3.25 OD. I'm guessing the reducer on there now is 3.25-3.00. I could probably make it work, but they're only around 10 bucks, so I'll just order one.

Ok, I'm confused on Maxbore's pricing:

TB boring price list



PLEASE CLICK ON "PLACE AN ORDER" AT THE TOP OF THE PAGE TO PAY USING PAYPAL

All the prices listed throughout the website include return shipping. what I list is what you pay.

CABLE OR DRIVE BY WIRE TBs, ALL BRANDS.

Stock TBs up to 70mm $125 Paypal or $120 Money Order(M/O) made out to Maxbore.

Stock TBs from 70mm and up $155 Paypal or $150 M/O made out to Maxbore.

HONDA/ACURA/SEADOO, CABLE ACTUATED TBs

$105 paypal or $100 M/O made out to Maxbore.



Is the $105 for only cable actuated Honda/Acura TB's (that's how I'm reading it) or all Honda/Acura TB's in general, including DBW? But, $105 is what I paid last year for my stock one. I measured the ZDX at 69mm, so do I Paypal him 105 or 125?

Sonnick

I gave him $150. I'll PM you an email Anx.

DomGSR-T

iTrader: (1)

the 70mm listed size must be the inside side (manifold) of the TB...

i_love_cars

iTrader: (1)

oh i definitely relocated the IAT. I just didn't have to do anything special because my aem v2 intake already had a bung for it that it threads right into.

anx1300c

iTrader: (2)

All the parts in bold are included in the cover assy, so you don't need them or #5 actuator assy.

Also you only need two of the 94050-08080 and two 95701-08060-08. There are two studs, 92900-08050-3B that go into the manifold, then the two nuts above secure the TB to those studs, and the two bolts above take care of the other two holes.

Also, way better prices here with half price shipping. I forgot the damn code though for 1/2 shipping:

I completed the install yesterday. I also install my new AEM V2 with a bung for the IAT. After the initial start up, I got a CEL. But after a day of driving, it went away. Didn't notice much yesterday, but today.....OMG! My butt dyno felt a difference; especially mid to top end. Thanks i_love_cars and Sonnick; very satisfied with this mod!

BTW I'm going to the dyno shop next week.

i_love_cars

iTrader: (1)

nice man, yeah the CEL is always possible initially - I had one for a very short while before I had my bored TB on there, it was for the IAT. Once the ECU figured it all out, it's been fine. I've probably got 600 miles without a CEL now.

and yes, mid to top-end gains quite a bit from this.

Did you ever get the JnR ecu hooked up?

Ok sorry for the late post. Got my dyno last Wed on a Dynojet. I’m having issues posting my actual dyno sheet, but the following is the data from the before dyno with the PnP stock IM and the after dyno with the 4G IM/ZDX TB.

Dyno run 06 Jan 12: First run - 252HP/224TQ
Second run – 251HP/225TQ
Third run – 251HP/226TQ
Air/fuel - 14
Air temp - 72
Humidity - 8
Pressure - 30

Dyno run 14 Nov 12: First run – 253HP/222TQ
Second run – 255HP/224TQ
Third run – 253HP/224TQ
Air/fuel -10
Air temp - 51
Humidity - 35
Pressure -31

According to the dynos, I only got a 3hp gain, but 2tq lost. So the swap wasn't much different from the PnP don't on my stock IM. With that being said, I still love the swap for three reasons. The weight lost, looks better and cooler IM due to the magnesium.

DomGSR-T

iTrader: (1)

Thanks for the results, so what was your TB size on the before runs? I know your stock IM was PnP but what about the TB? and what about the stock runners? Thanks for your time

t0talacuratl

iTrader: (3)

My TB and runners were untouched. The IM was PnP to match the TB.

anx1300c

iTrader: (2)

Damn. $650-700 (rough cost if not having TB ported) is a shit ton of money for a 10 lb lighter, prettier manifold.

3gstealth

iTrader: (2)

I weighed everything together at the same time to get the true weight savings. Each mani was weighed With cover and TB bolted on and the difference was only 5.5lbs. At first the 3.7 mani seems a ton lighter because the butterflies are not in it, they are located in the cover so the cover on the 3.7 is much heavier which negates some of the weight savings. To make it a fair comparison everything replaced must be weighed.

anx1300c

iTrader: (2)

Interesting. I was planning to weigh everything like you said, with everything installed on the manifold.

Sonnick

Total, look at the difference in your AFR. That's crazy. That's your issue right there. If you can post your dyno that would be great. The AFR change seems extreme. What are your mods? I think you need to do the ported runners as well, that may help.

Were the correction factors the same? Is it the same dyno? What kind of dyno? Like I said, my manifold was ported as well and I still gained 15whp. I also have the ported runners, gasket matched manifold, and bored TB as well.

anx1300c

iTrader: (2)

Good catch, Sonnick. That's pig rich, which is odd, considering this mod should lean things out, if anything.

Has anything wierd been going on with the car, Total? Wondering if something else is up.

Ok finally able to post up my dyno's.

Here is the before dyno. Disregard the 016 run; the shop did not compare the highest numbers.



Run 015 is the highest run prior to stock TB, PnP IM, stock runners...



Here is the run after the swap....ZDX TB, 4G IM, stock runners



2004 Acura TL 6MT, 160,000 miles
Mod list as follows: AEM CAI V2, 4G Intake Manifold, ZDX Throttle body, RV6 Precat Deletes V3, RV6 V3 J-pipe, Custom Catback (Greddy piping, Magnaflow/Vibrant resonators, and Borla mufflers), Outlaw Intake Manifold Spacer, Clutch Masters Stage 3 w/Lightweight Flywheel, Check Valve Delete, HT-Spec Version 2.0 Type-II Coilovers, Innovative Motor Mounts.

iTrader: (3)

Ok got ahead of myself here; the numbers below is the stock TB, PnP IM, stock runners.

Dyno run 06 Jan 12: First run - 252HP/224TQ
Second run – 251HP/225TQ
Third run – 251HP/226TQ
Air/fuel - 14
Air temp - 72
Humidity - 8
Pressure - 30

I was sent a zip file of all of my runs by the shop, but can't figure out the program to download and open them. Sonnick, I can send you the files if you can take a look at them.

anx1300c

iTrader: (2)

So you went from 239 to low 250's with the only mod being porting the stock manifold? IIRC, didn't you do a lighter flywheel during that time frame as well? That may have freed up a few of those extra horses, but the porting was probably responsible for the majority of it. Also, I bet the Outlaw spacer is hurting your top end. I remember reading that P2R said once you start porting/polishing the manifold/runners/TB, the addition of the MDX spacer would hurt top end power if you also had PCD's. I don't know the size of the Outlaw (don't think it's as thick as the MDX), but it still might be hurting the top end with the freer flowing manifold/TB.

Sonnick

That spacer is definitely hurting your top end a bit. Also, not taking anything away from the V3 pipe because it's a great piece, but I think the primaries are just too long once you mix them with the PCDs. I think a shorter primary length is optimal once you incorporate the PCDs into the equation. This is just my opinion though.

Btw, the AFR looks pretty similar between the 2 runs with the exception of 6500 to redline. What happened in the last graph with the blue line?

DomGSR-T

iTrader: (1)

Where do they plug the O2 on the car when they run it on the dyno? is the wideband O2 really inside the muffler like 6-8inches deep or just near the tips? The AF seems too flat/perfect? and also too lean for a oem ecu?

t0talacuratl

iTrader: (3)

Man I can't believe I forgot to mention that. You're so right about the clutch replacement. It definitely made a big difference. I can't remember how thick the Outlaw spacer is, but it's a little skinner than the P2R IM spacer. When I did the MDX spacer install with the PnP stock IM, it didn't perform well. But as soon as I swap the MDX with the Outlaw one, it was so much better! So I can testify to that. I can also try removing the spacer and dyno it, but do you think it will be that much of a difference?

Did not know that about the j-pipe. I had the XLR8 V1 on before the RV6 V3j-pipe. I do admit that I had more low end with the XLR8. But it was a clearance issue for me. But I thought the longer the primaries the better? If I were to go to a shorter primary, the ATLP V2 would be the best choice. Also my custom exhaust isn't the best, but hopefully I can get it corrected today.

As far as the AFR, not sure what happened there. I could ask the shop what's going on there.

I can't say for sure man; I wasn't in the bay during the run. They just had the monitor to watch the analog/digital gauges in the waiting room.

Sonnick

Like I said it's not a fact, it's just what I think. That's why we need some dyno's of 1 car with the different Jpipes and PCDs. That would explain it all.

OP, any updates?

Sheeee's a big one!

81mm inlet/71-72 outlet. Got the P2R gasket and coupler and clamps. Fed Ex tried to drop off the manifold and everything else today, but I was gone. They'll be back Friday, so I should be able to do the swap then.
