TSX IM on its way!

So this is the intake manifold I ordered off EBay. Only $95 w/free shipping!
Can anyone's confirm that this is the right intake? I've seen this stamp say a couple different things on different intakes.

Thinking About Doing This Swap

I drive the 2007 Accord, and I am a bit curious as to what the "attached resonator box" (aka chamber assembly) actually does?

It does what all resonator's do... tones down noise.

The resonance chamber increases midrange torque, this is partly why the K24A8 makes more torque and at a lower rpm than the K24A4.

Thank you!

I wonder if it is pointless to do the TSX IM swap (in 7th gen Accords with the resonator box) then?

 

[outersquare]

I am just guessing at this point, but I suspect it might still help. The TSX manifold still has a bigger plenum, whereas the stock K24A8 plenum still seems small. The torque increasing resonator chamber seems targeted for a specific RPM range for midrange improvement.

Additionally for the 06-07 K24A8 you should use the 06+ TSX IM and the larger throttle body that comes with it. However this might drive the need to replace the intake since I am not sure if the stock snorkel will fit the larger TSX TB.

Interesting. Gonna do the swap soon, I'll let you know if I "feel" a difference...

 

[JimmyFL]

Did the swap!

Well after 8 years and 130k miles, my starter went out...so since I would have to remove the IM anyways, I decided to replace the starter and do the swap.

With the new manifold, be it placebo or not, I feel a difference. There's an increase in acceleration and throttle response--well worth it.

On a side note, I'm sure most of you know this, but Autozone gives a lifetime warranty with their starters!

 

[waldo1324]

hi do we have the part numbers for these TSX manifolds?

the larger TB one and the 'regular' one

 

[outersquare]

The part numbers can be pulled from an online catalog such as acuraautomotiveparts.org

The early one (~2004 TSX) is suitable for the cable linkage accords (03-05) and later (~2006) is suitable for electronic throttle accords (06-07).

Here you go, but you should always double check other people's work;

2006 TSX IM
17110-RBB-A00

2004 TSX IM
17110-RBB-000

does anyone know if it would be a good idea to use the lower tsx intake manifold?

 

[kenshin]

does anyone know if it would be a good idea to use the lower tsx intake manifold?

it would fit since it's the same unit as the intake manifold. but i heard someone here tried it and it threw an engine code and he ended up put the accord lower part back in to get rid off the code.

DO NOT use the TSX injector base !!! Get a spare Accord version for your year and port it to match the TSX intake manifold. Experience talking ...

Planning on doing this mod. Found a 2006 tsx manifold plus throttle body about $80 shipped. I want the throttle body attached to the tsx manifold, because I don’t want to go through the trouble of removing the accord throttle body and scraping old gasket and cleaning mating surfaces, etc. Also, since the tsx throttle body is 4mm larger than the accord’s I’m planning on getting a CAI that fits the tsx. Looking at pictures the tsx and accord intakes seem to be routed the same way. The one question I have is, which intake manifold gasket should I use? The 2006 tsx or the 2007 accord?

It’s a 2007 accord 2.4L 5MT Sedan

I used the Acura gasket, only because it was easier to get from my friend who worked there before I started.

That member was @povy if I remember correctly ... his experience was exactly why I port and polished a spare Accord unit.

I port matched using the TSX gasket's as reference ... the gasket between the TSX intake manifold and Accord injector base, and then used the TSX gasket between the injector base and the head. *the gaskets may be the same part number ?

 

[ahmadamir]

Did you also port match the head?

 

[bobbo]

Did you also port match the head?

I port matched the injector base to the head yes.

So for clarity, I used the TSX intake manifold gasket to port match both the intake manifold and injector base flanges, and then used the TSX injector base gasket to port match the injector base for the head openings. I did not touch the openings on the head itself.

I installed a (used) TSX intake manifold/throttle body and now I am having an issue where the car almost dies when hitting the gas more than a little bit from a stop. If I take off gently it has no issue but if I give it a fair amount of gas from a stop it almost stalls and then accelerates. I did install a short ram intake at the same time but ruled it out as the issue persisted with the factory airbox. I did connect the small vacuum line the the back of the manifold.

I have disconnected the battery, done the idle relearn twice, took the manifold back off and cleaned the mating surfaces, checked for vacuum leaks with starting fluid, and tried some random Honda TB relearn but nothing has worked so far. I am away from the vehicle until tomorrow but ill check the live data for AFR and fuel trim, see if its spiking lean or if something else is weird there.

Should I just keep driving it and see if it gets better? It seems to not be as bad after some driving but still very much there. I know the ECU adjusts itself but this seems like too big of an issue to compensate for. I put about 10-15 miles on it after disconnecting the battery, I will drive it more tomorrow night and see if it continues to improve. Is there some sort of specific throttle body procedure I need to do? The one I did was just found in a google search.

I gotta say the torque increase is fantastic, you can actually accelerate fairly quickly under 2k rpm and it doesn't work nearly as hard at medium throttle to reach highway speeds. Its almost silent under normal acceleration but is pretty loud when flooring it. I just wish it didn't almost stall every time I take off from a stop.

Edit: The short ram intake was the majority of the issue. It sent the long term fuel trim to 18% and would spike to 22:1 when you stabbed the gas. I (regretfully) removed it and its much better now. Still does it a bit but not bad. Dont buy cheap ebay parts.

I got an 07 Accord 2.4 manual. I did a TB coolant bypass. I installed the tsx throttle body and intake manifold. Plugged all sensors, connected all hoses, and plugged that small nipple. I'm getting a pretty iradic idle and it dies. I received code p0108 for the MAP sensor. I tried trading the tsx and Accord map sensors, didn't change anything. I read a good amount of this thread, but found nothing. Any help??
