TSX Intake Manifold DIY / Q & A

[Asim]

How do you tell apart an 04-05 IM from 06-08?

I found someone on K20a for an IM but he hasn't a clue which one it is

here are the pics:

I have this one that i pulled off my k24.. if your interested let me know what it is worth to you.

It comes with fuel rail but no injectors.

also comes with the throttle body.

Part # should be stamped on the IM

For 2003-2005 Accords:

TSX Intake Manifold - 17110-RBB-000

For 06+ Accords:

TSX Intake Manifold - 17110-RBB-A00

That's not a TSX IM.  It has a cable TB.  All TSX TB's are DBW.

Turns out that had part number RAA

Hey guys I just installed my TSX IM yesterday and I can tell theres a power difference but did you guys do anything else...what i mean is do I need to change the injector base at all or is it the same on both cars? The only difference I can tell is that when I'm driving and take off from a rolling start it has more power other than that nothing else really changed.

You don't need to change the base. Just swap IMs and keep on rockin...

cool thanx

How do you tell apart an 04-05 IM from 06-08?

By the book:
The 04-05 IM throttle opening has a diameter of 60mm.
The 06-08 IM throttle opening has a diameter of 64mm.

I don't think that will make a difference in performance for the Accord, unless you've bored out your Throttle Body to match the diameter.  

A more obvious difference is that the throttle body openings are different between the two.  
The 04-05 IM throttle opening has somewhat of a rectangular shape routed out, making it key shaped.
The 06-08 IM throttle opening is a circle.  

My question is, what purpose does that key shape on the 04-05 IM serve?  I've noticed this design on the stock Accord IM's, and gaskets as well.  

PS.  More info and pics can be found here:  http://www.tsxclub.com/forums/1st-gen-engine/42435-tsx-intake-manifold-mods-4.html#post632040
(The IM with the Throttle body studs is the 04-05, and is in fact, the one that Tim sold me.  You can't tell how clean it is, but heck, that IM's getting famous, Tim!)

The reason for the "key" shaped hole is because the Accord uses an IACV on the TB.  The TSX doesn't use that, so that's why there is a mystery about it being on the TSX IM.  How is the IM famous?

Might be another option that I just found.

Holy fucking expensive batman. Would it fit in our bays? That one just goes straight out instead of going down like ours. I think I remember reading somewhere that those Skunk2 intake manifolds are no good for low end torque, and the only increase you can get is past the RPM range our cars can handle. I would take a $60 TSX IM over a $500 Skunk2 IM any day, haha.

Tim, I'd also like to point out that the part number for the 06-07 Accord throttle body gasket is 16176-RTA-004, and the 03 sealing cap is 90634-PA0-000. That part of the guide hasn't been updated.

If anyone's around the Winter Haven / Lakeland area in FL, I'd be more than willing to help you out. I've still got an extra 03-05 throttle body gasket because the one on my car stayed intact.

[Paulius005]

Oh I would take the OEM one over that too, but if people are looking for the most gains possible that may be an option. Plus, I'm curious to see if it would fit .

[CrackerTeg]

It would bolt on/ fit without a problem but with our stock engines, you'd lose power and not be able to use that manifold to its potential. That maniold is designed for high RPM performance where our stock k24a4/8 engines fall flat on their face. Now, others that swapped their heads/ engines out (Tim, Skip, Blinx) would benefit from this if they were sticking with an NA setup. If Tim were to ever hand his SC over to me, this would be a good NA upgrade for him.

[timot_one]

If you think the Skunk2 is expensive, then don't look at the IPS intake manifold.

Does anyone know where i can get a tsx intake manifold?
